- BACKGROUND
Granulomatous mastitis (GM) is a rare chronic inflammatory condition that clinically mimics a carcinoma.
The diagnosis of idiopathic GM depends on the exclusion of other granulomatous inflammations. The purpose of this study is to correlate the clinicopathological features of GM with etiologies.
METHODS
We reviewed the clinical records of 58 cases that were histologically diagnosed as GM. We performed special stains for microorganisms such as Ziehl-Neelsen, periodic acid Schiff and gram stains, and polymerase chain reaction (PCR) for Mycobacterium tuberculosis (TB PCR).
RESULTS
The mean age of patients was 35.3 years. Most patients were parous except three. Seven patients (12.1%) were related with pregnancy or lactation. TB PCR was positive in nine patients (15.5%). Five patients (8.6%) had gram positive bacilli that were recognizable as coryneform bacteria. Culture study demonstrated Staphylococcus aureus in only one case. Infectious GM had a greater tendency to form abscesses. Fat necrosis was more likely to be present in idiopathic GM, but other histological features were similar to each other. Twenty-two cases (37.9%) showed recurrence.
CONCLUSIONS
We suggest that TB PCR and gram stain are essential tests for the differential diagnosis of GM, because the histologic features considerably overlap irrespective of the various etiologies.

- In diagnosing a brain tumor, it is essential to obtain samples from many areas of the tumor. Although there are reports about the suitability of material obtained by cavitron ultrasonic surgical aspirator(CUSA), there is a paucity of reports regarding conventional intraoperative suction. This study was performed to evaluate the usefulness of the suction fluid and the effect of different hemolytic fixatives. Intraoperative suction fluid was obtained from 2 pituitary adenomas and 2 choroid plexus carcinomas. In two cases of mixed astro-oligodendroglioma, one of glioblastoma multiforme and 3 of meningioma, the fluid was collected by CUSA. Each sample was divided into four bottles for the different fixatives such as 0.1N HCl, 10% acetic acid, 95% alcohol, and no additive. All cases were evaluated by the both cytologic smear and cell block preparations, and were reviewed with concomitant histologic diagnosis. The result showed a good correlation between the cytologic study and the histologic diagnosis and 95% alcohol was found to be superior to other fixatives in cell preservation.

- Dieulafoy's vascular malformation is a rare cause of massive gastrointestinal bleeding.
Most often it occurs in stomach within 6 cm from the gastroesophageal junction. Only a few cases have been reported to occur in the small intestine and colon. Occasionally, Dieulafoy's lesion of small intestine is difficult to recognize because of rarity, a paucity of symptoms and negative findings on barium studies.
Therefore, this lesion needs to be considered in a patient with massive lower gastrointestinal bleeding. We report a case of Dieulafoy's vascular malformation in ileum 2 m proximal to ileocecal value in a 41-year-old woman who visited emergency clinic because of hematemesis, dizziness and vomiting. Small intestine revealed a wide-caliber artery within the submucosa showing intimal thickening, medial muscular hypertrophy and thrombosis.

- Status of margins and the size of the lesion are independent prognostic factors of ductal carcinoma in situ (DCIS). Histologic grading of DCIS and expression of biologic marker also appear to act as prognostic factors. However, DNA ploidy analysis using flow cytometry in the DCIS and atypical ductal hyperplasia (ADH) has been rarely reported, and the biologic behavior of ADH is unknown. We performed immunohistochemical staining and DNA ploidy analysis using flow cytometry on 45 cases of pure DCIS without microinvasion and 34 cases of ADH to compare the expression of biologic markers and DNA ploidy patterns according to the histologic grade of DCIS, to evaluate the usefulness of the Van Nuys classification, and to investigate the biologic behavior of ADH and low grade DCIS.
A total of 41.9% of DCIS and 32.1% of ADH were detected mammographically in asymptomatic patients. The most common subtype of the high grade DCIS was comedo type (56.3%), while the low and intermediate grade DCIS were cribriform type. Expression of ER, c-erbB-2 and Ki-67 proliferative index (PI) was significantly associated with nuclear grade and histologic grade of DCIS. Expression of c-erbB-2 was also significantly correlated with presence of necrosis. In low grade DCIS, Ki-67 PI was significantly higher than ADH. A total of 63.6% of DCIS and 70% of ADH were diploidy and 15.9% of DCIS was aneuploidy. There was no aneuploidy in ADH. No significant association was noted between DNA ploidy and histologic grade or nuclear grade. However, in high grade DCIS, the frequency of aneuploidy was high. In conclusion, histologic grading of DCIS employing nuclear grade and necrosis is a useful tool accounting for biologic behavior.
High grade DCIS and comedo DCIS impart aggressive biologic behavior and suggest a higher possibility of local recurrence or progression to invasive carcinoma. In the differential diagnosis of ADH and low grade DCIS, the use of Ki-67 PI and DNA ploidy analysis by flow cytometry will be helpful for accurate diagnosis and prediction of biologic behavior.

Abstract

- Diabetic mastopathy is a clinicopathologic entity which was first described as a dense fibrous breast mass in insulin-dependent diabetes mellitus. The purpose of this article was to document diabetic mastopathy histologically which had been diagnosed as fibrocystic disease and to avoid unnecessary surgical procedures in breast mass simulating malignancy in diabetic patients. We examined eight excisional breast biopsies from seven patients. Three diabetic patients with type I insulin-dependent diabetes mellitus presented with bilateral (2 patients) or unilateral (1 patient) rapidly growing palpable breast masses. Four patients with type II noninsulin-dependent diabetes mellitus presented with bilateral (2 patients) or unilateral breast mass (1 patient). One patient had no symptoms. All of them had late complications of diabetes mellitus such as nephropathy, neuropathy and retinopathy. Mammographic findings such as ill- defined mass density and asymmetric increased density suggested malignancy. However, all of them had been diagnosed as fibrocystic disease. On review, the most consistent pathologic finding was keloid-like stromal fibrosis. Others were ductitis or ductulitis, thickening of basement membrane of ducts or ductules, mononuclear perivasculitis and lobulitis. Six of eight breast satisfied all five criteria for diabetic mastopathy.

- DNA ploidy analysis using flow cytometry was performed on sixty six cases of phyllodes tumor of the breast including benign, low grade and high grade malignant phyllodes tumor. The rate of aneuploidy was 41.2% in high grade malignant phyllodes tumor and 4.8% in benign phyllodes tumor. No aneuploidy was noted in low grade malignant phyllodes tumor. The recurrence rate according to DNA ploidy pattern revealed 16.7% of aneuploidy and 7.7% of diploidy. In the aneuploid cases, the DNA index of high grade malignant phyllodes tumor was higher than benign phyllodes tumor.
Morever, in diploid cases, %SG2M were significantly higher in high grade malignant phyllodes tumor. Therefore, we conclude that DNA ploidy analysis as well as histologic characteristics such as cellularity, pleomorphism of stromal cells and mitoses is useful parameters in the diagnosis, recurrence and prognostic predictors of phyllodes tumor.

- A 58-year-old female with an episode of gross hematuria two months before and fever and chill for the past three days presented oliguric acute renal failure. She has taken NSAID intermittently for 18 years due to rheumatoid arthritis, and herb medicine for one week two months ago when gross hematuria developed. Physical examination revealed mild tenderness on costovertebral angles. Her blood pressure was 170/100 mmHg, the urinalysis showed >300 mg protein with many RBCs and 10-20 WBCs and the serum creatinine was 5.8 mg/dl. A renal biopsy performed on the 4th hospital day showed that it was overwhelmed by severe tubular lesions which reveal intratubular obstruction by massive erythrocyte casts and tubular necrosis. The glomeruli showed focal minimal crescents with many red blood cells entrapped in the crescents and in the capillaries. Immune deposits were not present. A renal failure resolved spontaneously and the patient was discharged three weeks later with creatinine of 2.4 mg/dl. In this patient, acute renal failure was considered to be due to a tubular lesion related to the glomerular bleeding from focal glomerulonephritis revealing minimal crescents.

- Subcutaneous fat necrosis is manifested by erythematous tender nodules on the legs, buttock or trunk and is associated with pancreatic disease including acute and chronic pancreatitis, pancreatic carcinoma, pseudocyst, pancreatic stone and other diseases. Its histologic findings are pathognomonic and reveal foci of subcutaneous fat necrosis with "ghost-like" anucleated cells with thick "shadowy wall" and surrounding inflammatory infiltrate consisting of polymorphonuclear cells, eosinophils, lymphocytes, histiocytes, foam cells and foreign body giant cells. We experienced a case of subcutaneous fat necrosis associated with pancreatic adenocarcinoma manifested by subcutaneous nodules in the buttock and lower extremities and by arthralgia of the left knee in a 67-year-old woman.
Therefore, we are reporting to emphasize the importance of the skin findings of the internal disease.

- Angiosarcoma of the bone is rare with an incidence of 0.13%.
It may be solitary or multiple. Its cytologic findings by FNA have rarely been reported. We report a case of angiosarcoma of the rib in a 66 year-old man. FNA revealed single or clusters of round to oval shaped cells in a hemorrhagic and myxoid background. The large central nuclei had irregular nuclear membrane, chromatin clumping and prominent nucleoli. The cytoplasm was scanty with an eosinophilic distinct cytoplasmic border.
Erythrophagocytosis by malignant cells was also found.
Histopathologic examination confirmed the diagnosis of angiosarcoma revealing irregular and com- plex anastomosing vascular channels lined by malignant round tumor cells, protruding into the lumen. Immunohistochemical staining revealed diffuse strong positive reaction to factor VIII-related antigen and CD31.
