A rare case of schwannoma on the foot: diagnostic challenges and clinical management

Year: 2025

Type: article

Abstract: Schwannomas are benign peripheral nerve sheath tumors commonly found on the head, neck, and extremities, but they rarely occur on the feet and toes. Here, we present a case report of a 70-year-old woman with an ulcerated tender mass with an uncommon location on the lateral aspect of the left fifth toe. The tumor was initially misdiagnosed as hyperkeratosis, delaying correct treatment. Histological reassessment confirmed the diagnosis, schwannoma, highlighting the clinical challenges with diagnosing schwannomas due to their nonspecific appearance, and in this case, unusual presentation on the toe.
