What is Fibro-osseous Pseudotumor of the Hand: a Case Report of a 22-Year-old Young Woman about?

We present a case of a 22-year-old patient with an important expansive neoformation of the soft tissues near the proximal phalanx of the fourth finger of the right hand. There was no evidence of past direct traumas, wounds, or local infections. The Rx, CT scan and MRI exams showed a lesion of the soft tissues measured around 3 × 2 × 2.8 cm, without hinting at a connection with the bone structure with a hypointense signal in T1 and an isointense signal in T2. First diagnostic speculations pointed at a giant cell tumor of the tendon sheath (GCTTS). Since there seemed to be no indication of a malignant tumor, it was decided to execute an excisional biopsy on the patient, rather than an eco-guided core needle. The imaging studies of the histological characteristics showed spindle-shaped elements with low-grade atypia, fibromyxoid and osseous stroma in different maturity stages, and always delimited by osteoblast cells. Osteoclastic giant cells were also found, as well as foci of osseous metaplasia peripherally aligned around proliferating cell aggregates. Considering all the following data, the final diagnosis clearly indicated a fibro-osseous pseudotumor of digits (FOPD). At the last
