Abstract
PDF - Glycogen-rich clear cell carcinoma of the breast is an unusual variant of carcinoma with a recorded incidence of 1.4-3% of breast carcinomas. The cytologic characteristics have not been well described. We report two cases of glycogen-rich clear cell carcinoma with corresponding fine needle aspiration(FNA) cytologic findings and compare them to infiltrating ductal carcinoma and other clear cell malignancies with a review of literature. One was a 62-year-old woman exhibiting a palpable mass of the right breast. The smears showed atypical tight cell clusters and individually scattered single cells containing foamy or clear abundant cytoplasm with well defined cytoplasmic margins. Mild to moderate nuclear pleomorphism and a prominent nucleolus were present. The other was a 42-year-old woman who was admitted with a right breast mass. The smears showed moderately cellular, tightly cohesive tumor cells. The cytoplasmic outline was generally well demarcated. The tumor cells contained foamy to clear abundant cytoplasm with large and small vacuoles. The nuclear pleomorphism was marked. Both tumors resected by modified radical mastectomy, were diagnosed as glycogen-rich clear cell carcinoma. Histologically, the clear cell nature of tumor cells were not characteristic enough to predict this type of the tumor. Some cytologic features can be distinguished other clear cell breast cancer from glycogen-rich carcinoma. Recognition of these unusual patterns in a breast FNAC should raise the suspicion of a clear cell carcinoma including glycogen-rich subtype. Cytological localization of glycogen using PAS and D-PAS staining may permit the correct identification and differential diagnosis of this tumor.

Abstract
- Glycogen-rich clear cell carcinoma of the breast is very rare(l -3% of breast cancer). It is defined as a tumor composed of more than 50% of optically clear, neoplastic cells, characterized by centrally located nuclei and abundant cytoplasm, being positive for periodic acid Schiff(PAS) and negative for periodic acid Schiff after diastase(D-PAS) treatment. In the absence of intraductal or in situ lobular carcinoma component, metastatic clear cell carcinomas of other organs should be considered as diagnostic possibilities. We report a case of glycogen-rich clear cell carcinoma arisen in a 62-year-old woman. The tumor revealed both solid and papillary pattern with intraductal component. The neoplastic cells had clear cytoplasm, which were PAS positive, D-PAS negative, mucicarmine negative and oil red 0 negative. More than 90% of tumor cells exhibited moderate staining for anti-estrogen receptor monoclonal antibody. Flow cytometric DNA analysis revealed diploid DNA content.

Abstract
PDF
- Oxyphilic clear cell carcinoma of the ovary is a variant of clear cell carcinoma with abundant eosinophilic cytoplasm described by Young & Scully in 1987. Thorough samplin is needed to identify typical foci of clear cell carcinoma for the differential diagnoses from a variety of ovarian tumors with oxyphilic cells. We report a case of oxyphilic clear cell carcinoma in a 65-year-old female patient who presented with vaginal spotting and lower abdominal discomfort. The excised mass was a 10x8x7cm sized, well circumscribe yellowish white solid ovarian tumor. Microscopically, the tumor showed glandular, papillary and alveolar growth patterns composed of cuboidal or hobnail-shaped oxyphilic cells.
