Abstract:
Malignant eccrine poroma is a rare malignant cutaneous tumor arising from intraepithelial eccrine duct and it may develop either spontaneously or from a long standing eccrine poroma. We report a case of malignant eccrine poroma on the antihelix of the right ear in a 37-year-old female, previously diagnosed as a benign eccrine poroma with shave biopsy specimens. Histological findings are well-defined tumor cell nests disseminated in dermis. Each cell has a large, hyperchromatic atypical nuclus. The atypical mitoses, dyskeratoses, intracytoplasmic vacuolations and duct-like structures are observed. She was treated with wide surgical excision and local skin flaps.
