ABSTRACT
Mohs' micrographic surgery is an approach to selected skin cancer removal that aims to achieve the best prospect of total tumor excision simultaneously with maximal functional and cosmetic preservation. The advantage of the technique is that 100% of the surgical margin of the specimen, including the periphery and deep surface, can be examined intraoperatively by horizontally oriented frozen sections. This method offers cure rates significantly higher than conventional excision or other modalities. Mohs' micrographic surgery is the method of choice for removal of large, recurrent or incompletely excised skin cancers or for tumors located in functional and aesthetic relevant anatomic regions. The authors present a case of a 75-year-old man with a second time recurrent plantar invasive malignant melanoma successfully treated with Mohs' micrographic surgery technique and an immediate reconstruction using split-thickness skin graft.
