[Soft tissue chondromatosis of the foot: diagnosis and therapy]

Chondromas of the soft tissue are uncommon, benign tumors. They are most frequently found adjacent to periarticular tissues or tenosynovium with a predilection for the hands and feet. We report a case of a patient with a large, increasing tumor of the left foot. Because of subjective complaints and mechanical irritation the patient was scheduled for surgery. The preoperative radiological work-up showed popcorn like clusters of calcifications around the dorsum of the foot. The tumor mass was reduced using several incisions. Histology showed soft tissue chondromatosis of the foot without malignancy. Following the operative procedure, the patient was free of pain and able to wear normal shoes. This case illustrates the clinical and radiological characteristics as well as the surgical treatment of progressive soft tissue chondromatosis.
