A case of porocarcinoma from pre-existing hidroacanthoma simplex: need of early excision for hidroacanthoma simplex?
BACKGROUND
Hidroacanthoma simplex (HAS) is an uncommon eccrine neoplasm of the skin. It is a benign neoplasm, but some cases of malignant change were reported in the literature.


OBJECTIVE
To describe a rare case of porocarcinoma in a relatively short period from pre-existing HAS on the abdomen.


METHODS
Wide local excision was performed on this neoplasm.


RESULTS
There was no recurrence for 72 months after wide excision. CONCLUSION. : We recommend an early excision and careful attention in the case of HAS because of its potential malignant change.
