Ovarian primary malignant melanoma is very uncommon with only 44 reported cases in the literature. A 71-year-old woman with an ovarian mass and multiple nodules in the liver presented to our hospital. She was treated with bilateral salpingo-oophorectomy, and malignant melanoma was found in the mature cystic teratoma of the ovary. Malignant melanoma cells were also found in the ascitic fluid. She died 5 months later. Here we report a very uncommon case of malignant melanoma arising in an ovarian mature cystic teratoma with a review of the literature.

Abstract PDF

BACKGROUND
The epidermal growth factor receptor (EGFR) is known to be involved in many tumor promoting activities. EGFR inhibition has been tried as a therapeutic modality in many human malignancies.
METHODS
The expression of EGFR protein and the gene copy number changes were studied in 135 clear cell carcinomas and 16 papillary renal cell carcinomas (RCCs), and these tumors were diagnosed between 1995 and 1997.
RESULTS
An EGFR protein expression (2+ and 3+) was found in 54.1% of the clear cell RCCs and in 43.8% of the papillary RCCs. In the clear cell RCCs, its expression was associated with male gender, the tumor size (> or =4 cm) and high T stages (T2 and T3), with statistical significance. Trisomy and polysomy of the EGFR gene were found in 27 (25.7%) and 40 (38.1%) of 105 clear cell RCCs, respectively. Trisomy and polysomy were correlated with an EGFR protein expression and a high clinical T stage, with statistical significance. Among 15 papillary RCCs, 13 tumors showed trisomy (86.7%) and one showed polysomy (6.7%). Amplification was not found in both the clear cell and papillary type RCCs.
CONCLUSIONS
A considerable numbers of RCCs showed an overexpression of EGFR protein and increased EGFR gene copy numbers, yet the clinical significance of conducting a FISH study in RCC patients seems to be limited.

Extramedullary B Lymphoblastic Crisis of CML, Presenting as a Leptomeningeal Tumor: A Case Report.: Hoiseon Jeong, Bongkyung Shin, Sook Young Bae, Sangho Lee, Youngjune Ryu, Hankyeom Kim, Insun Kim; Korean J Pathol. 2009;43(5):482-488.; DOI: https://doi.org/10.4132/KoreanJPathol.2009.43.5.482

Abstract PDF: We report here on a rare case of a patient who presented with an extramedullary B lymphoblastic crisis as an initial manifestation of chronic myelogenous leukemia (CML). A 71-year-old man visited the emergency room due to suddenly developed dysarthria and right side weakness. Emergency craniotomy was done under the presumptive diagnosis of subdural hemorrhage. During the operation, a poorly demarcated firm mass was identified in the leptomeningeal space. Microscopically, the majority of the tumor was composed of monotonous immature cells with blast morphology, and these cells were immunoreactive for TdT, CD34, CD10 and CD20, indicating the precursor B-cell phenotype. The peripheral area of the tumor consisted of myeloid cells in various stages of maturation, and these cells were reactive for myeloperoxidase, chloroacetate esterase, CD43 and CD15. FISH analysis using the LSI bcr-abl dual color probe showed gene fusion signals in both the B-lymphoblasts and myeloid cells. The peripheral blood and bone marrow findings were consistent with CML with no evidence of a blast crisis. Cytogenetic study of the bone marrow demonstrated the 46, XY, t(9;22)(q34;q11) chromosome. A diagnosis of extramedullary B lymphoblastic blast crisis in a patient with Philadelphia chromosome-positive CML was made. Despite treatment, the patient died 3 months after he was diagnosed.

Pathological Characteristics of 20 Cases of Langerhans Cell Histiocytosis and Specificity of Immunohistochemical Stain of Langerin (CD207).: Youngjoon Ryu, Hyunjoo Lee, Sangho Lee, Hoiseon Jeong, Bongkyung Shin, Aeree Kim, Hankyeom Kim, Insun Kim; Korean J Pathol. 2009;43(2):113-119.; DOI: https://doi.org/10.4132/KoreanJPathol.2009.43.2.113

Abstract PDF

BACKGROUND
Langerhans cell histiocytosis (LCH) is a well-known neoplastic disorder of Langerhans cells which has characteristic findings, however, LCH has not been adequately studied in Korea.
METHODS
We analyzed the clinicopathologic features of 20 patients with LCH who were diagnosed between 1997 and 2006 at the Korea University Guro and Anam Hospitals.
RESULTS
The M:F ratio was 3:1 and the age ranged from 2-60 years (mean, 23.8 years [4 in 1st decade, 6 in 2nd decade, 2 in 3rd decade, 5 in 4th decade and 3> or =40 years of age). The cases were classified as unifocal unisystemic in 13 patients, multifocal unisystemic in 4 patients, and multifocal multisystemic in 3 patients. The bone was the most commonly involved organ (14), followed by lymph node (5), lung (2), skin (2) and ureter (1). The Langerhans cells were immunohistochemically stained with Langerin, CD1a, S-100 protein, and CD68. Langerin and CD1a were specific for Langerhans cells.
CONCLUSIONS
The distribution of the involved organs in patients with LCH was similar to the distribution in Western countries, but lymph node involvement was more frequent, whereas lung involvement was less common. Langerin is considered to be a specific marker for Langerhans cells.

Abstract PDF: Uterine adenomyoma is a neoplasm that is composed of endometrial glands and smooth muscle, and this is found in the uterine corpus; however, the glandular component is occasionally of mucin-secreting endocervical type. We describe here a case of uterine adenomyoma of the endocervical type, and this presented in a 38-year-old pregnant woman.
