A case of fibro-osseous pseudotumor of the digit

Fibro-osseous pseudotumor is an unusual ossifying fibro-proliferative lesion. Typically, this lesion affects the young adults, mainly women, and presents as a painful, localized, fusiform, and often erythematous swelling in the soft tissue of the fingers, especially the region of the proximal phalange. We present a case of fibro-osseous pseudotumor on the left index finger of a 22-year-old woman. Diagnosis was confirmed by histopathologic features, followed by complete excision of the lesion. At the 7-month follow-up, there was no recurrence. We suggest that fibro-osseous pseudotumor should be considered in the differential diagnosis of any digital mass.
