6. Comment First described by Hermann Pinkus in 1953.
It is a rare variation of basal cell carcinoma with very indolent
clinical course.
Unlike other histologic types of basal cell carcinoma, the tumor occurs commonly on the sun-protected skin of trunk, especially back.
Presents as a slowly enlarging, fleshy, raised or pedunculated papilloma or achrochordon with a broad base on the trunk or the extremities.
Age: Older adults, M=F
Histology: Fibroepithelioma of Pinkus shows long, thin, branching and anastomosing strands of basal cell carcinoma within in a fibrovascular stroma. Many strands show a connection with the epidermis. The basaloid strands show two types of cells: a lighter staining cell comprising the bulk of the strand and peripheral, small darker cells showing palisading pattern.
