Desmoid fibromatosis of the cruris: A rare case report

Desmoid Fibromatosis (DF) is a locally aggressive connective tissue neoplasm that arises within the musculoaponeurotic structures. It is also referred to by various terms, including aggressive fibromatosis, deep fibromatosis, musculoaponeurotic fibromatosis, and desmoid tumor. DF is a rare tumor, with a reported incidence of 2-4 cases per million population, accounting for approximately 0.03% of all neoplasms. It most commonly occurs between the ages of 15 and 60 years and tends to be more prevalent in females. Although DF can develop in various anatomical locations, it is most frequently observed in the extremities, abdominal wall, and intra-abdominal mesentery. Despite lacking metastatic potential, DF has a high propensity for local recurrence. Due to these biological characteristics, DF is currently classified as an "intermediate, locally aggressive" tumor according to the World Health Organization (WHO) classification of soft tissue tumors. This report presents a clinical case of desmoid fibromatosis.
