Plantar Fibromatosis and Other Fibroblastic and Fibrohistiocytic Soft Tissue Tumors of the Foot

Plantar fibromatosis, also known as Ledderhose’s disease, is a benign fibroblastic disorder of plantar aponeurosis, more specifically the medial side of the foot arch. Magnetic resonance imaging (MRI) has an important role in the diagnosis, staging, and determining the deep extension found in advanced, aggressive forms of plantar fibromatosis, thereby guiding appropriate clinical and surgical management. This case report aims to provide radiologists and clinicians with simple guidelines for the differential diagnosis of the fibroblastic and fibrohistiocytic soft tissue tumors of the foot with the emphasis on the MRI findings.
