Keywords: Eccrine porocarcinoma, Scalp

Objective: Eccrine porocarcinoma is a rare malignant tumor of eccrine sweat glands. It may arise de novo, but it usually develops in pre-existing eccrine poroma. Here we report a case of eccrine porocarcinoma in the grafted area on the scalp of a male patient who had recurrent basal cell carcinoma of the scalp, with clinical, histopathological and, immunohistochemical features.

Case: We report a case of eccrine porocarcinoma in 78-year-old male patient who had recurrent basal cell carcinoma of the scalp. The tumor was polypoid, granular and heterogenous colored. Microscopic examination revealed a tumor composed of basaloid-poroid neoplastic cells in the dermis which showed solid and cystic areas. Focal clear cell change, and atypical and frequent mitoses were also observed. Neoplastic cells were diffusely positive with pankeratin. There was focal positivity with EMA and CEA.

Conclusion: Eccrine porocarcinoma is a rare tumor. There are no large series that evaluate the diagnosis, monitoring and treatment of these tumors. In addition, this entity has to be kept in mind in the differential diagnosis of epidermal and skin appendix tumors.
