Eccrine Porocarcinoma on the Lateral Nose Wall: A Rare Case Report

Eccrine porocarcinoma (EPC) is an uncommon malignant tumor derived from the eccrine sweat glands. We present a case of EPC on the lateral nose wall, in which the tumor was excised, and the resultant defect was reconstructed using a nasolabial flap. A 66-year-old female was referred to the Department...

Sumario:Eccrine porocarcinoma (EPC) is an uncommon malignant tumor derived from the eccrine sweat glands. We present a case of EPC on the lateral nose wall, in which the tumor was excised, and the resultant defect was reconstructed using a nasolabial flap. A 66-year-old female was referred to the Department of Plastic and Reconstructive Surgery to receive treatment for a cutaneous tumor on her right lateral nose wall, which had been growing rapidly for 3 months. Histological analysis of a biopsy specimen of the tumor suggested that it was a squamous cell carcinoma. Surgical excision was performed with a 3-mm margin. The tumor was histologically diagnosed as an EPC. EPC exhibits various pathological features; therefore, it is often confused with other malignant cutaneous tumors. We consider that histologically examining surgical specimens obtained via total resection, rather than incisional biopsy specimens, is important for correctly diagnosing EPC.
