Multiple metachronus proliferative fasciitis occurring in different anatomic regions: a case report and review of the literature

Proliferative fasciitis is a benign lesion that usually has a self-limited course and rarely recurs after excision. In the literature, the multifocal occurrence of PF in different anatomic sites has not been reported so far. In this report, we describe the clinical case of a 30-year-old woman with two metachronous proliferative fasciitis occurring firstly in the orbit and, after 18 months, in the forearm; we also review the available literature on this topic, outlining guidelines for therapy and the follow-up of these patients.
