Abstract
Fibro-osseous pseudotumour of the digit (FOPT) is a rare, benign lesion of proliferating spindled myofibroblasts found in the soft tissue of the distal aspect of the digits. Misdiagnosis as malignant neoplasms such as osteosarcomas results in needlessly aggressive surgery and hinders reconstruction. We report the case of a 6-year-old girl presenting with an enlarging lesion of the left hallux for over a year, causing elevation of the medial nail fold of the left big toe over the distal phalanx. An incisional biopsy was undertaken revealing a lesion histopathologically consistent with a diagnosis of fibro-osseous pseudotumour. Accurate diagnosis through clinical reasoning and histopathology prevented digit amputation.
