Abstract
- Hidroacanthoma simplex is a benign tumor believed to arise from the uppermost segment of the intradermal eccrine duct and the acrosyringium, and histologically shows intraepidermal focal growth. A malignant counterpart to this tumor is rare and named malignant hidroacanthoma simplex or porocarcinoma in situ. We report a case of atypical hidroacanthoma simplex, which is considered to be a malignant transformation of benign hidroacanthoma simplex in a 83- year-old female.
