AbstractAbstract PDF
Apocrine carcinoma arising from the apocrine sweat glands is a rare cutaneous malignant tumor which occurs predominantly in the axilla of elderly individuals. The typical histologic features of apocrine carcinoma is within a well developed glandular lumina with abundant eosinophilic cytoplasm and evidence of decapitation secretion. In rare instances, predominant signet ring cell features in apocrine carcinoma has been reported. We experienced a case that occured in the right axilla of a 59-year-old. Histopathologic examination showed a solid tumor that extended from the upper dermis into the subcutis, with a delicate infiltrate of epithelial cells. The cells had granular amphophilic cytoplasm, predominantly showed distinct signet ring cell morphology, and were strongly positive for epithelial mucin. Both lysozyme and gross cystic disease fluid protein-15 were identified in the tumor cells. We diagnosed this to be a case of primary signet ring cell apocrine carcinoma of the axilla after several immunohistochemical and clinical evaluations.

AbstractAbstract PDF
DNA prevalence and type distribution of human papillomavirus (HPV) varies geographically. We investigated HPV prevalence and type distribution in Korean women using the MyHPV DNA chip testing. Methods: A total of 2,368 women from five regions of the country underwent Pap smear examination and MyHPV chip testing. Results: Overall HPV positivity was 15.8% and 78.4% in women with normal and abnormal cytology, respectively. High-risk HPV infection was strongly correlated with cytological atypia. In women with abnormal cytology, the five most common HPV types were 16, 58, 18, 52, and 56/53, and HPV16 was significantly the most common type in most geographical regions. After HPV16, HPV58, and 52 were the next most frequently detected types. Women with normal cytology, in contrast, showed heterogeneity in HPV type distribution. High-grade intraepithelial lesions infected with HPV16, 18, 31 or 45 are more likely to progress to carcinoma. Conclusions: The HPV chip test can provide useful data regarding HPV positivity and type. The most common HPV type in Korean women with abnormal cytology is HPV16, with HPV58 and 52 being frequently present. Our data may have important implications for vaccination programs and the development of cervical screening.

AbstractAbstract PDF
ras gene mutations have been described in various human malignancies, suggesting that their activation may play a role in oncogenesis. However, there are few reports concerning ras gene alterations in malignant fibrous histiocytomas. We therefore designed a study to determine the prevalence and type of mutations in the first exons of H-ras and K-ras genes in these tumors.
Twenty-seven malignant fibrous histiocytomas were investigated by direct sequencing analysis with the automated DNA sequencing of polymerase chain reaction-amplified ras sequences.
Twenty-four mutations were found in 18 (67%) of the tumors: GGC to GAC transition mutations at codon 13 of K-ras (coding for aspartic acid instead of glycine) in 18 of the samples and GGC to GTC transversions at codon 12 of H-ras (coding for valine instead of glycine) in six of the lesions.
Our data suggest an involvement of the ras gene mutation in conjunction with other yet unknown events in the tumorigenesis and/or progression of malignant fibrous histiocytomas. The K-ras gene activation predominated in these tumors by a mutation at codon 13. It is noteworthy that H-ras mutations were detected only in association with the lesions containing K-ras mutated genes, the significance of which remains to be determined.

AbstractAbstract PDF
Altered cell cycle regulation may underlie the development and/or progression of human malignancies. The purpose of this study is to determine if the oncogenesis of soft tissue sarcomas could be better explained by examining the components involved in G1 phase progression.
Sixty-seven soft tissue sarcomas were studied for the immunohistochemical expression of cdk4, cyclin D1, retinoblastoma (Rb) and p16 proteins. For Rb and p16, samples showing either negative or heterogeneous (<80% of tumor cells) staining were considered to be altered.
The cdk4 protein was observed in 64 cases (95.5%). Cyclin D1 was expressed in 14 cases (20.9%). The Rb expression was altered in 48 (71.6%). Sixty-three (94%) sarcomas demonstrated altered p16 expressions. All of the samples displayed altered expressions of either Rb or p16. A high percentage of the tumors with altered Rb were observed in relapsed patients (p<0.05).
Disturbance in the cell cycle regulatory system involving the Rb/p16/cdk4/cyclin D1 pathway appears to be relatively frequent in soft tissue sarcomas and may play an important role in the tumorigenesis of these tumors. It is noteworthy that the reduced Rb expression correlates with tumor relapse, suggesting its prognostic significance.

AbstractAbstract PDF
Acinic cell carcinoma(ACC) is the third common malignancy in major salivary gland. Fine needle aspiration cytology is a useful tool for the diagnosis of salivary gland lesions. However, some low grade malignancies, such as ACC and mucoepidermoid carcinoma show relatively high false negative rate, mainly due to deceptively benign cytomorphologic appearance. We experienced a papillary-cystic variant of ACC, having different cytopathologic features compared with those of classic ACC. Our case showed monolayered sheets and papillary clusters without any acinic structures or naked nuclei of the tumor cells. Foamy proteinaceous material was seen in the background. The tumor cells had a large amount of granular cytoplasm and eccentric nuclei. Many vacuolated or clear cells were also noted.

AbstractAbstract PDF
Trichoblastic fibroma is a benign trichogenic tumor that has both epithelial and mesenchymal components and exhibits partial follicular induction. We studied 4 cases of trichoblastic fibroma and reviewed their clinical and histologic features. Two tumors were present in the face. The remaining two were in the vulva and perianal area, respectively. The age of the patients ranged from 53 to 68 years, with an average age of 62. All were female. Histologically, the lesions showed a well circumscribed mass, located at dermo-subcutaneous junction in three patients and subcutaneous in one. They demonstrated mesenchymal induction evidenced by hair germ-like structure and perifollicular sheath. There was no connection between the tumor and epidermis. Differentiation toward hair structure led to the formation of the infundibulum through inner root sheath. Trichoblastic fibroma may be confused clinically and/or histologically with basal cell carcinoma. Identification of the mixed epithelial and mesenchymal components, and the absence of epidermal connection and cleft within the stroma are important in differentiating this benign neoplasm from basal cell carcinoma.

AbstractAbstract PDF
Matrix metalloproteinases (MMPs) and their inhibitors (tissue inhibitors of matrix metalloproteinases, TIMPs) play essential roles in the remodelling of the extracellular matrix. The balance between MMPs and TIMPs is altered in neoplasia, contributing to the invasive and metastatic properties of malignant tumors. Although MMP and TIMP are believed to play an important role in invasion and metastasis in malignant solid tumors, little is known about their involvement in malignant lymphoma. Immunohistochemical stains for MMP-1, MMP-2, MMP-9, TIMP-1 and TIMP-2 were performed using 56 paraffin blocks of the malignant lymphoma and the results were analyzed by using the tumor grade by Working Formulation. The expression of MMP-9 was noted in 45.5% of low grade, 86.1% of intermediate grade, and 100% of high grade malignant lymphoma. The incidence of MMP-9 expression in tumor cells was positively correlated with the grade of the malignant lymphoma (P<0.025). In nodal lymphomas, the incidence of the MMP-9 expression of the tumor cells was higher in malignant lymphoma with extracapsular invasion than those without extracapsular invasion (P=0.008). The incidence of TIMP-1 expression in the tumor cells and fibroblasts was positively correlated with the grade of the malignant lymphoma (P<0.025). In nodal lymphoma, the incidence of the TIMP-1 expression of the tumor cells was higher in malignant lymphoma with extracapsular invasion than those without extracapsular invasion (P=0.009). The incidences of the MMP-1, MMP-2, and TIMP-2 expression in malignant lymphoma were neither increased in the malignant lymphoma with extracapsular tumor invasion nor correlated with the grade by working formulation. There was no significant difference in the expression rate of MMP-1, MMP-2, MMP-9, TIMP-1, and TIMP-2 in nodal- and extra-nodal malignant lymphoma. The above results suggest that the expressions of MMP-9 and TIMP-1 are positively correlated with the grade and the presence of extranodal tumor invasion in malignant lymphomas.

AbstractAbstract PDF
We report a case of necrotizing arteritis involving the gallbladder. This case was clinically diagnosed as cholelithiasis with cholecystitis, and necrotizing arteritis was found in the surgically resected specimen. Vascular changes were similar to those seen in classic polyarteritis nodosa, involving medium-sized muscular arteries and characterized by fibrinoid necrosis and panarterial and periarterial inflammation varying from active to resolving stages. Acute cholecystitis is a rare initial clinical manifestation of the systemic vasculitis. If acute cholecystitis is found in the absence of obvious cause, careful examination is essential. Since steroid therapy improves the prognosis in the systemic vasculitis, clinicians and pathologists should be aware of this unusual lesion.

The clinical and pathological features of warty dyskeratoma are presented. Warty dyskeratoma is a rarely encountered, solitary, benign cutaneous tumor occurring most often on the head and neck and to our knowledge, no cases associated with cutaneous horn have been published in western literature. We experienced a case of warty dyskeratoma with a cutaneous horn occurring in a 70-year-old male, who had a 1.3 cm-sized and slowly growing nodule on his neck. A brief review of the literature, was made especially in relation to the pathological findings and histogenesis of warty dyskeratoma.

Paneth cell-rich carcinoma is essentially an adenocarcinoma with a predominance of Paneth cells. A 60-year-old male patient was admitted with a history of abdominal distension for several months. Endoscopic examination revealed a large ulceroinfiltrative tumor involving most of the areas of the stomach. The biopsy of the lesion confirmed poorly differentiated adenocarcinoma and total gastrectomy was followed. The submitted total stomach contained a diffuse infiltrative Borrmann type IV mass with ulceration, 8.0 3.5 cm, at the body along the lesser curvature. Microscopically, it was composed of Paneth cell differentiated cancer cells and poorly differentiated tubular adenocarcinoma cells. The Paneth cell differentiation was characterized by cytoplasmic coarse eosinophilic granules, which were PAS-positive and positive reaction for lysozyme. Electron microscopic examination showed numerous, spherical, electron-dense, homogeneous granules corresponding to those in Paneth cells as well as mucin granules in the signet-ring cells, and various intermediate forms in some cancer cells, which might be immature in the Paneth cell lineage.

AbstractAbstract PDF
Intracystic papillary carcinoma(IPC) of the breast is a distinctive and very rare variant of intrductal carcinoma. The cytologic features of IPC have been rarely reported, and there are difficulties in distinguishing between benign and malignant papillary breast lesions. Herein we report a IPC of the breast in a 80 year-old female. Fine needle aspiration cytology revealed monotonous cuboidal epithelial cells in small clusters and individually scattered on bloody background. The tumor cells did not show overt cytologic atypia. With the histologic features of this case and review of the literature, the cytologic differential points are discussed.
