Bilateral Hypertrophy of Abductor Digiti Minimi Simulating a Localized Soft Tissue Mass: A Case Report

Abstract

Soft tissue tumors of the foot have a low incidence rate, and most of them are symptom free, thus it is difficult to diagnose accurately. Herein, we report a 15-year-old male patient who had swelling without pain on the lateral margin of both feet. We performed excisional biopsy of the abductor digiti minimi via subtotal resection, following radiograph and magnetic resonance imaging. According to the histological analysis, hypertrophy of abductor digiti minimi was positive, and other soft tissue tumors were negative. Six months after the operation, normal appearance of both feet was maintained and the patient was satisfied with the result.

Idiopathic Hypertrophy of Abductor Digiti Minimi Muscle: A Case Report

“…The patient needed a complete excision of the remnant muscle and partial excision of the exor digiti minimi brevis muscle with no recurrence. The other case was described by Jung et al in 2017 10 . They described a 15-year-old male who had swelling without pain in the lateral margin of both feet.…”
