The authors report a case of mucinous carcinoma of the male breast firstly diagnosed as a mucinous carcinoma of the skin. The immunohistochemical results of this tumor were as follows: cytokeratin7 (-), gross cystic disease fluid protein 15 (-), p63 (-), estrogen receptor (+), and progesterone receptor (+) for the primary nodule; cytokeratin7 (-), thyroid transcription factor-1 (-), gross cysti...
Clear cell tumor of the lung (CCTL) is an extremely rare neoplasm with about 50 cases reported in the literature so far. CCTL belongs to a family arising from putative perivascular epithelioid cells and is otherwise named as "sugar tumor" due to its high cellular glycogen concentration. Due to its rarity, diagnostic features of this entity are not widely known and this usually leads to misdiagn...
Cytological examination of body fluids is important for the diagnosis, staging and assessment of prognosis in malignant lesions. Based on morphologic features alone, cytological differentiation of reactive mesothelial cells from adenocarcinoma is found to be difficult. Therefore, ancillary studies often are performed to assist in the differential diagnosis. We have done this study to evaluate t...
Epithelioid angiosarcoma of the parotid gland is rare, and may pose a great diagnostic challenge. We report a case of primary epithelioid angiosarcoma in a 64-year-old male without history of radiation. The histopathological findings demonstrated a high grade epithelioid neoplasm. Immunostaining showed that the tumor was positive for the pan-cytokeratin, p63, cytokeratin18, Vimentin and vascula...
Intestinal type of lung adenocarcinoma (ILADC) was initially described by Tsao and Fraser in 1991. Morphology and immunophenotype of ILADC are the same as in colorectal adenocarcinoma. Rectocolonoscopy must be performed to exclude colorectal origin of adenocarcinoma. Colorectal adenocarcinoma claimed to be genetically similar to an ILADC. Patients. We describe 24- and 26-year-old patients of bo...
Background & Objective: The role of synchronized expression pattern of cytokeratin (CK) 7 and CK20 in the prognosis of colon adenocarcinoma is unclear. The current study aimed at determining the relationship between the expression of cytokeratins 7 and 20 and prognostic factors in colon adenocarcinoma. Methods: In the current cr...
