Fibro-Osseous Pseudotumour of the Digit: An Illustrative Case and Review of the Literature.

Fibro-osseous pseudotumour is a rare, benign ossifying tumour of soft tissue that should be considered in the differential diagnosis of any tumour affecting the digits. Clinical diagnosis is difficult and fibro-osseous pseudotumour is often mistaken for malignancy, leading to inappropriate treatment. Knowledge of its clinical and histopathological features thus allows for appropriate primary treatment, sparing the patient from unnecessary radical surgery associated with presumed malignancy. We present the case of a 48-year-old male with fibro-osseous pseudotumour affecting the right ring finger, successfully treated with local excision. This is the second reported Australian case of fibro-osseous pseudotumour, and we present an extensive review of the literature relating to the diagnosis and management of this rare tumour.
