Özet

Keratotic basal cell carcinoma may not only clinically but also histologically share more or less the same features with giant solitary trichoepithelioma. It can be difficult to distinguish these two entities from each other, even for an experienced dermatopathologist. We present an unusual case of inguinal keratotic basal cell carcinoma mimicking giant solitary trichoepithelioma in a 56-year-old woman with a finger-like tumor of 20 years duration. The patient presented with an asymptomatic, skin colored, firm, nonulcerative, nodular lesion. Scanty mitotic activity and apoptotic cells were the histopathologic findings against basal cell carcinoma, whereas absence of papillary mesenchymal bodies, presence of peritumoral lacunae detected only around the solid areas, and accumulation of amyloid-like hyalinized material were the findings in favor of basal cell carcinoma. This case illustrates that keratotic basal cell carcinoma must be taken into account in the differential diagnosis of inguinally located solitary, polypoid masses, especially giant solitary trichoepithelioma.
