초록

Basaloid squamous cel carcinoma is an unusual variant of squamous cel carcinoma that mostly arises in the upper aerodigestive ly aggressive, and is often presented at advanced stages with lymph node or distant metastasis. It most commonly occurs in the larynx, hypopharynx and the base of the tongue. Histologicaly, basaloid squamous cel carcinoma is characterized by a basaloid pattern often intimately asociated with focal squamous diferentiation, comedonecrosis, and stromal hyalinization. This tumor ern, but is usually distinguishable in routine hematoxylin and eosin stained sections, or in rare cases, with the aid of imunohisto-chemical studies. We report a case of basaloid squamous cel carcinoma that ocurred in the right palatopharygeal fold of the oropharynx, which is a distinctly unusual location.
