Exploring trichoblastic carcinoma of scalp through immunohistochemistry and histopathology

Trichoblastic carcinoma is a rare malignancy. Here, we present the case of a man in his mid-40s with a recurrent ulcer. Histological findings are positive for trichoblastic carcinoma. The patient completed radiotherapy and is currently on chemotherapy. Trichoblastic carcinomas have no retraction clefts or peripheral palisade. Immunohistochemistry (IHC) was done to narrow the diagnosis further, showing CD-10 positivity. Since their management methods vary, we emphasise differentiating basal cell carcinoma from trichoblastic carcinoma.
