Clear cell sarcoma presenting as an interdigital neuroma.
The incidence of malignant soft-tissue sarcomas in the general population is approximately 1.4 per 100,000. Approximately 2% of all cancer deaths are attributable to these tumors. Presented is a case history of a soft-tissue malignant neoplasm that was originally thought to be an interdigital neuroma and that eventually required a modified Chopart's amputation. A review of the literature is presented on other soft-tissue malignant tumors that have an affinity for the foot and ankle. The intention of presenting this case is to caution physicians that malignant lesions can simulate a benign process and should always be considered in the differential diagnosis of any foot mass.
