title: Rhabdoid phenotype in squamous carcinoma. A report of two cases.
abstract: We report two cases of squamous carcinoma in which a prominent rhabdoid phenotype was seen. The tumors which occurred in the buccal mucosa of a 70 year old man and the skin of a 85 year old man were positive for cytokeratin and epithelial membrane antigen indicating their epithelial nature. Co-expression of vimentin was also noted. The aggressive nature of the rhabdoid component is confirmed by the fact that the cervical lymph node metastasis in case I was also rhabdoid.
