Giant Lipoma of the Hallux: A Rare Clinical Presentation about a Case Report

Tumors of the soft parts of the foot are rare lesions. The main inconvenience of these lesions is the difficulty or impossibility of putting on a shoe, which becomes very disabling in the case of a giant lipoma. We report the case of a 59-year-old patient who presented with a giant lipoma of the hallux. Clinical examination revealed a painless, mobile mass measuring 9 cm × 6 cm, soft, and circumferential throughout the metatarsophalangeal joint of the hallux; it extended dorsally and continued in a palmar region involving the first commissure. A magnetic resonance imaging of the right foot confirmed a large oval mass, fairly well limited, in T1 and T2 hypersignal, erased on the STIR sequences. An excisional biopsy was indicated and performed, leading to the conclusion of a lipoma of the right hallux with no sign of malignancy. The evolution was marked by partial skin necrosis treated by managed healing. After 12 months, there was good skin healing, no sign of clinical recurrence, and the patient was satisfied and had begun wearing shoes again. Lipomas are benign tumors which develop slowly and painlessly. They rarely occur in the foot. Large tumors can be uncomfortable because of the conflict they can cause when putting on shoes.
