Malignant aneuploid spindle-cell transformation in a proliferating trichilemmal tumour.

A case of spindle-cell carcinoma developed on a proliferating trichilemmal tumour (PTT) is presented. The tumour on the scalp of an 84-year-old white woman was excised and histological examination showed typical features of PTT, but with a coexistent malignant spindle-cell tumour with a sarcomatoid appearance. There were some areas of transition between squamous trichilemmal epithelium and the neoplastic mass composed of atypical spindle-shaped cells.
