چکیده
Merkel cell carcinomas (MCCs) are uncommon, highly malignant skin tumors that develop in sun-exposed areas of the skin. Most of the MCCs are CK 20-positive and CK 7-negative such as our case. About 80% of Merkel cell carcinoma is associated with Merkel cell polyomavirus.

The author reports a very rare case of spindle cell carcinoma (SpCC) of the urinary bladder progressed from ordinary papillary transitional cell carcinoma (TCC). A 63-year-old man complained of hematuria. A transurethral endoscopic examination revealed a papillary tumor, and transuthetral resection of bladder tumor (TUR-BT) was performed and was diagnosed as ordinary papillary urothelial TCC. S...
متن کاملThe overexpression of salivary cytokeratins as potential diagnostic biomarkers in head and neck squamous cell carcinomas
BACKGROUND Cytokeratin (CK) intermediate filaments are demonstrated to have enormous potential in regulating cellular motility and cancer progression. There are more than 20 divergent CKs that have been identified, of which CK 8, 17, 18 and 19 are reported to be elevated in the tumour biopsies of head and neck cancer squamous cell carcinoma (HNSCC) patients. However, CK expression profiles in t...
