Slow Mohs Micrographic Surgery and Reconstruction With Artificial Dermis for Atrophic Dermatofibrosarcoma Protuberans: A Case Report

This case report describes the utility of artificial dermis in reconstruction for atrophic dermatofibrosarcoma protuberans (DFSP) after slow Mohs micrographic surgery (MMS). A 34-year-old man presented as a slowly growing nodule from an atrophic scar on his right chest for over 10 years. The pathology report confirmed the diagnosis of atrophic DFSP. Further magnetic resonance imaging (MRI) revealed a 9.3 cm x 6.5 cm cutaneous-subcutaneous lesion with close contact with the pectoralis major muscle. The patient underwent a slow MMS, and we utilized a rotational flap in combination with synthetic xenogeneic artificial dermis to reconstruct the final 13 cm x 12 cm defect.
