Cutaneous papillary squamous cell carcinoma. Report of three new cases and review of the literature.
Squamous cell carcinoma is one of the most common malignant cutaneous tumors. Several histological variants have been described; the papillary subtype is one of the most infrequent, with only four cases having being reported previously. We report three new cases of this unusual variant of cutaneous squamous cell carcinoma, review the literature and consider the main differential diagnoses. Polymerase chain reaction performed in our three cases did not demonstrate human papilloma virus infection.
