Introduction:

Porocarcinoma is a strange neoplasm of the skin, which develops in the sweat glands at the intradermal ductal portion.

Case Report:

We describe the case of a 65-year-old Mexican patient with a long clinical history of skin lesion, which was successfully treated with surgical treatment, and a 3-year recurrence-free interval.

Discussion:

This tumor represents from 0.005% to 0.01% of skin tumors and is the most frequent of the eccrine malignant tumors. It predominantly affects people in the fifth and eighth decade of life; the most commonly affected areas are the lower limbs. The treatment of choice is still the wide surgical resection with Mohs micrographic surgery, whose cure rate ranges from 70% to 80%.

Conclusions:

Although porocarcinoma incidence rate is very low, its biological behavior turns it aggressive when the disease spreads. In spite of its low frequency, it is still a diagnose challenge.
