A SURGEON'S SURPRISE TO VERRUCOUS GROWTH OVER CHEEK - CASE REPORT ON MALIGNANT ECCRINE POROMA

Abstract

Malignant eccrine poroma is a rare malignancy of eccrine glands , whose diagnosis is an index of high suspicion and challenging to a clinician. A case of 67 year old female with swelling over left cheek since 20 years with no radiation exposure and no comorbidities , was investigated and wide local excision with 5mm margins from the tumor was performed , and specimen sent for biopsy - which revealed tumor cells arranged in lobules with peripheral palisading , ductal and squamous differentiation - suggestive of Porocarcinoma.Wide surgical excision is the mainstay of treatment, resulting in cure rates of 70–80% when the margins are clear. Some studies also reported good outcomes with Mohs micrographic surgery, and this technique could also be considered 1. Other treatments such as chemotherapy and radiotherapy have also been reported in the literature without clear standard guidelines.
