Modified Mohs micrographic surgery for the treatment of five cases of eccrine porocarcinoma / 中华皮肤科杂志

ABSTRACT

Objective:To investigate the efficacy of modified Mohs micrographic surgery in the treatment of eccrine porocarcinoma.Methods:Clinical data were collected from 5 patients with eccrine porocarcinoma, who treated with modified Mohs micrographic surgery in Department of Dermatology, Wuhan No.1 Hospital from 2016 to 2020, and retrospectively analyzed.Results:Among the 5 patients, 2 were males and 3 were females, their age ranged from 52 to 80 years, and the course of disease ranged from 1 to 50 years. Skin lesions were located on the scalp, face, abdomen, thighs and feet, with diameters ranging from 1 to 6 cm. Tumor excision was performed with 1-cm margins, and was deep to the superficial fascial layers. For histopathologically negative surgical margins, the defects were closed with skin flaps or grafts; for histopathologically positive margins, the excision margin continued to be widened until it was clean. The 5 patients were followed up for 1 - 5 years without recurrence, and 1 died 2 years later due to liver cancer metastasis.Conclusion:Modified Mohs micrographic surgery can ensure clean resection margins and reduce the loss of normal tissues in the treatment of eccrine porocarcinoma.
