Background

Although chemotherapy-related hepatic injury has been reported in colorectal cancer liver metastasis (CRLM) patients, the morphologic changes caused by chemotherapeutic agents and the effect of chemotherapy on postoperative outcome remain ill-defined. A comprehensive review of the morphologic changes in the post-chemotherapy non-neoplastic liver was performed and the clinical effect of preoperative chemotherapy in CRLM patients was analyzed.

Methods

Hematoxylin-eosin, Masson's trichrome and reticulin-stained slides from non-neoplastic livers obtained from 89 CRLM patients were analyzed, and the clinicopathologic features were correlated with the status of chemotherapy exposure.

Results

Histopathologic features of sinusoidal injury (sinusoidal dilatation, centrilobular perivenular fibrosis, parenchymal extinction lesions, small vessel obliteration, and hepatocyte plate disruption) were significantly more frequent in oxaliplatin-exposed livers (p<0.05). The extent of sinusoidal dilatation was positively correlated with increasing numbers of chemotherapy cycles (p=0.022). Abnormal preoperative liver function tests were more frequently seen (p<0.05) and postoperative total bilirubin was higher in the chemotherapy group (p=0.008). Postoperative morbidity was more common in the chemotherapy group (p=0.044).

Conclusions

Sinusoidal injury is frequently seen in oxaliplatin-treated livers, and its presence, especially when extensive, should be documented in surgical pathology practice. The recognition of sinusoidal injury may provide helpful guidelines for surgeons in deciding the extent of hepatic resection.

Abstract PDF: Two cases of giant cell tumor of bone diagnosed by fine needle aspiration cytology are described. Case 1 was a 28-year -old male who had pain sense for one year at the right distal thigh. His radiologic finding revealed a destructive cortical lesion with soft tissue extension at medial side of epiphysis of the distal femur. Case 2 was a 21-year-old female complaining pain at left distal forearm for eight months and showed a well-demarcated expansile osteolytic lesion with multisepatation, and cortical destruction at epiphysis and metaphysis of the left distal radius on the X-ray. Fine needle aspiration of each lesion was performed. The aspirate of the case 1 reveated moderate cellularity, which was composed of scattered giant cells of osteoclastic type and small round to oval monotonous stromal cells in large areas. Giant cells were evenly distributed in single or small groups and had irregular but abundant cytoplasms with 10 to 20 nuclei in the center. The nuclei showed ovoid shape, fine granular chromatin, and a small but conspicuous nucleolus, Stromal cells were dispersed in isolated pattern or sometimes aggregated in clusters and showed the same nuclei as those of giant cells and scanty cytoplasms, Comparing to case 1, case 2 had a more translucent abundant cytoplasm in the giant cells and more spindled stromal cells, All two cases revealed neither nuclear atypism nor increased abnormal mitoses in both giant and stromal cells, suggesting no evidence of malignancy. Thereafter the lesions were treated with excision and curettage and histologically confirmed as giant cell tumors of the bone.

Abstract PDF: So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells having predominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei. The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchiotoalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.

Abstract PDF: We report a case of malignant tumor of the stomach showing both carcinoma and sarcoma components in a 47 year-old woman. The resected stomach revealed two tumors which were in different location. The one mass was a 2 x I cm, poorly demarcated tumor at the body, along the lesser curvature and the other was a 6 x 7 cm, well demarcated polypoid tumor with a central depression at cardia of the posterior stomach wall. The tumor at the body was a poorly differentiated adenocarcinoma which showed strong reactivity for CEA. The tumor at the cardia was composed of epithelioid or spindle shaped cells with abundant eosinophilic cytoplasm and revealed 5-6 mitoses per ten high power field. The tumor at the cardia was diagnosed as epithelioid leiomyosarcoma and showed reactivity for vimentin but none for actin, desmin,keratin, and CEA. This is different from the usual carcinosarcoma.

Abstract: This paper describes a student-centered case study program concerning the tumor pathology course for first year students in medical school under the traditional curricular structure. A traditional, discipline-oriented, lecture-laboratory approach was partly modified by introducing a tutuorial session using a modified case matrix format during the laboratory hours without altering the general scheme of the existing system. Small group tutorial sessions were set with the development of learning objectives emphasizing clinicopathologic reasoning and early exposure to future practical presentation which was followed by the large class session; each tutorial was supplied with a short clinical history, gross kodachrome slides, and microslides. The session for problem identification was replaced by proving a series of instructor-designed questions for both pathology and interdisciplinary correlation during which pedagogical implication was stressed the most. Student's active participation, development of self learning skill and vigorous teaching-learning process among students, and motivation/relevance for forthcoming pathology study were among the benefits conferred by this modification. We conclude that this approach is an interim step to meet the advantages of problem-based learning even in a traditional curricular structure.

Abstract PDF: The assessment of epithelial changes in gastric mucosal biopsies has been one of the major problems caused by inconsistencies in and disagreements about nomenclature and interpretation. To resolve these issues, members of the Study Group for Pathology of Digestive Diseases reviewed microslides of 50 gastric lesions showing varying degrees of mucosal abnormality and reached the following consensus; 1) the proliferating gastric epithelium can be divided into hyperplastic and neoplastic; 2) the term "dysplasia" is reserved for the microscopic epithelial changes that are unequivocally neoplastic; 3) Biopsy specimens can be categorized as regenerative(negative for dysplasia), indefinite(questionable dysplasia), positive(positive for dysplasia) and overt carcinoma; 4) The positive category can be divided into two subgroups, high grade dysplasia and low grade dysplasia. Criteria for each grade are presented and discussed. We offer these guidelines for establishing the correct diagnosis of the gastric mucosal biopsy specimens and for prospective studies.

Abstract PDF: Hepatoblastoma is a rare malignant liver tumor found in children. Its biological characteristics and prognostic factors have not been well known. We investigated 29 cases of hepatoblastoma, registered in university hospitals in Seoul from 1984 to 1996. By the immunohistochemical method, p53, Waf-1 (p21), bcl-2, heat shock protein 70 (hsp70), c-jun, transforming growth factor-alpha (TGF-alpha) expressions were studied. Those data were compared with clinico-pathologic features; age, sex, tumor size, tumor stage and histologic subtypes. Expression of p53 and bcl-2 were each observed separately in single cases. Expression of c-jun was more frequently noted in patients at higher stages. Expression of TGF-alpha decreased in the order of pure fetal, mixed, embryonal and small cell anaplastic subtypes. Cumulative survival rate was lower in females than in males and in patients with a higher tumor stage. According to histologic subtypes, survival rates decreased in the order of pure fetal, mixed, embryonal and small cell anaplastic subtypes. Survival rate was lower in patients with c-jun expression. Group of TGF-alpha labelling index under 19 showed a lower survival rate than that over 19. In conclusion, we found that tumor associated proteins, c-jun and TGF-alpha, are closely related to the prognosis of hepatoblastoma but p53 and bcl-2 may not be related to it.

Abstract: Gastrointestinal polyposis (GIP) is a rare disease characterized by formation of the numerous polyps in the gastrointestinal tract and presenting several extraintestinal manifestations. Most of the diseases are transmitted in an autosomal dominant pattern. In Korea, the epidemiological study as well as the pathological analysis of the GIP is not well established. We therefore analysed 38 items of GIP using surgically resected specimens. The materials in this study were collected from the 12 institutions and case reports in Korean literature between 1980 and 1991. The clinicopathologic findings were reevaluated by several members of the study group for gastrointestinal pathology. The results are as follows: (1) A total of 112 cases were included in this study: 83 cases were collected from 12 institutions and 29 cases were collected from Korean literature. The cases were classified as familial adenomatous polyposis (FAP), 59 cases; Gardner's syndrome, 3 cases; juvenile polyposis, 12 cases; Peutz-Jeghers syndrome, 35 cases; multiple colonic adenomas, 3 cases. (2) Among 59 cases of FAP, the range of age at operation was 14 to 61 years, and a family history was positive in 25 cases. The number of polyps in colorectum was 100~8,000. Of the 37 cases in which the examination of polyp density was available, 16 cases (43%) showed the highest density in the rectum and the sigmoid colon. The carcinomatous change within polyp(s) was present in 18 cases (31%), and associated advanced single or multiple colonic carcinomas existed in 37 cases (63%). Twenty-six (45%) tumors out of total 58 carcinomas were in the rectum. Twenty-five patients were evaluated for the upper gastrointestinal lesions, and 11 patients (44%) had pathologic lesions; multiple fundic gland polyps in 3 cases (12%), gastric and duodenal adenomas in 2 cases (8%), gastric adenomas in 2 cases (8%), duodenal adenomas in 2 cases (8%), gastric carcinoma and adenoma in 1 case (4%), gastric carcinoma in 1 case (4%). (3) Among 3 cases of Gardner's syndrome, the range of age at operation was 25 to 31 years, a family history was identified in 2 cases. One case was associated with an advanced colonic carcinoma and carcinomatous change within polyp. Extra gastrointestinal lesions were sebaceous cyst, epidermal cyst, osteoma and desmoid tumor. (4) Among 12 juvenile polyposis, the range of age at operation was 8 to 51 years and 5 patients had a family history. The carcinomatous change within polyp was found in 2 cases (17%) and associated advanced colonic carcinoma was in 4 cases (33%). The associated different type of polyps was tubular adenomas in 9 cases (75%), hyperplastic polyps in 4 cases (33%) and villous adenomas in 2 cases (17%). (5) Among 35 Peutz-Jeghers syndrome, the range of age at first operation was 6 to 42 years, family history was positive in 11 cases. The carcinomatous change within polyp was found in 1 case (3%), and associated advanced colonic carcinoma in 1 case (3%). The epithelial misplacement was observed in 4 cases (11%), and tubular or villous adenomatous feature in 4 cases (11%). In summary, the most frequent GIP for the surgical resection in Korea is FAP and the FAP is associated with high incidence of coexisting advanced and intramucosal carcinomas. Hamartomatous polyposis syndromes, such as juvenile polyposis and Peutz-Jeghers syndrome are another frequent disease for the surgical resection and are also associated with an increased risk of cancer.

Abstract: This study outlines the current status of the autopsy practice and the medical records for autopsies at the Department of Pathology, Seoul National University Hospital. Total number of autopsy cases from 1954 to 1995 was 3,131. Adults aged over 17 were 371 cases and children were 2,515 cases. The demographic data in 245 cases was not available. The number of adult autopsies and its proportion among total number of autopsies during 10-year periods decreased from 144 cases (40%) during the 10-year-period from 1956 to 52 cases (3%) during the 10-year-period from 1986. The number of children cases during the same period groups increased slightly from 210 cases (58%) to 393 cases (25%). But the number of fetal cases increased rapidly from 7 cases (2%) to 1,146 cases (72%). Among fetal autopsies the proportion of fetuses died earlier than 24 weeks of gestation increased and this figure exceeds that of fetuses that died later than 24 weeks of gestation from 1992. Forty percent of the cases were submitted from the clinical departments of the Seoul National University Hospital but the remainders were referred from 73 hospitals. Final autopsy diagnoses were analysed according to the Korean Standard Classification of Disease (KCD)-3 coding system and by searching key words for all cases. Common diagnoses as coded among cases from 1990 were P9, P0, P2, Q2 and Q0. Common diseases by key words for adult cases were liver disease, tuberculosis and pneumonia. Common diseases for children cases were pneumonia, hyaline membrane disease, meningitis and tuberculosis. Through this study we could show the importance of autopsy services for fetuses. We could also establish a regular registration system for autopsies at general hospitals.

Abstract PDF: The terms chronic active hepatitis (CAH), chronic persistent hepatitis (CPH), and chronic lobular hepatitis (CLH) should be discontinued in favor of etiologic terminology. The activity of necro-inflammation and the degree of fibrosis should be evaluated for grading the severity and for the stage of disease. Members of the Korean Study Group for the Pathology of Digestive Diseases reviewed 30 cases of chronic hepatitis and reached the following consensus: 1) The pathology report of the biopsy samples with features of chronic hepatitis should include the etiology, grade and stage. 2) Grade and stage should be semiquantitatively evaluated as none, minimal, mild, moderate and severe. 3) For grading, lobular activity and periportal activity should be evaluated, separately. 4) To avoid confusion with other grading systems, simple report using descriptive terms rather than numerical records is recommended in daily practice. Criteria for each grade and stage should be presented and discussed. Histologic grading and staging of chronic hepatitis by new standardized guidelines will give more information about the prognosis as well as the present status of hepatitis. The terms CAH, CPH and CLH may be used in parentheses to facilitate relearning.

Abstract PDF: Leiomyosarcoma of the soft tissue is a well-defined and characteristic entity histologically, but cytomorphological studes are lacking. A correlative cytological study of 2 cases of leiomyosarcoma is presented. The smears from case 1 were rich in tumor cells and most cells were arranged in large sheets or clusters. The cells showed round to oval nuclei containing fine chromatin and small prominent nucleoli. The smears from case 2 were moderate in cellularity with loose clusters or isolated cells. The characteristic blunt-ended and cigar-shaped nuclei containing coarse chromatin and prominent nucleoli were identified in case 2. Nuclear atypia, prominent nucleoli and high cellularity permit diagnosis of malignancy, although the atypia is generally less pronounced than in the histology. The cytological diagnosis of leiomyosarcoma may be auxiliary in the diagnosis of recurrence or metastasis in the patients with alleged leiomyosarcoma.

Abstract PDF: A 70-year-old female who was diagnosed as myxoid chondrosarcoma by fine needle aspiration of a pleural mass is described. She presented with left chest discomfort of 4 months' duration and aggravating dyspnea and chest pain for 2 months. Chest X-ray and CT scan revealed a large lobulated low density mass invading chest wall at the left pleural cavity and massive pleural fluid. Fine needle aspiration was done under the impression of mesothelioma or metastatic cancer. The aspirates from the mass were very cellular and composed of isolated or clustered forms of large plump cells. Abundant cytoplasm was bluish opaque and the margin was rounded in the isolated cells, whereas clustered cells show ill-defined cell borders and aggregating tendency. The nuclei were eccentric, round to ovoid, and had fine chromatin pattern and multiple small nucleoli. Cellular pleomorphism or mitotic figure was not definite. These findings were consistent with cytologic features of chondrosarcoma. Final diagnosis was confirmed as myxoid chondrosarcoma by mediastinoscopic biopsy and the tumor showed strong positivity for S-100 protein.
