[Squamous cell carcinoma of the leg in an octogenarian woman]

An octogenarian woman developed lesions of the leg suggesting the diagnosis of cutaneous cancer at the dermatological examination. A biopsy revealed the carcinomatous nature of the neoplasm. An additional immunohistochemical examination was performed for scientific purposes. The neoplastic structures were not surrounded by a basement membrane and its framework of collagen IV. The dermal dendrocytes were abundant in the peritumoral stroma. This situation was previously interpreted as a favourable prognostic factor.
