Wide Local Excision for Eccrine Porocarcinoma of the Forearm

Eccrine porocarcinoma is a rare and aggressive cutaneous malignancy that develops in the seventh and eight decades of life. We present a 76-year-old male with eccrine porocarcinoma developing from a long standing previously benign lesion who underwent successful treatment with wide local excision. It can also develop de novo, presenting most commonly as a mass or nodule. Tissue biopsy with histopathology is required to confirm the diagnosis. Wide local excision is recommended for local disease. Radiation and chemotherapy can be used as adjuncts in advanced and metastatic disease. Given its rarity, there are no guidelines to direct therapy for locally advance or metastatic disease and for follow-up. Further studies are needed to better understand and guide management of this entity.
