Desmoplastic fibroma (desmoid) of the femur: 2 cases

Desmoplastic fibroma (extra-abdominal desmoid) was first identified as an independent nosological form in 1958 by H.L. Jaffe [6]. This tumor differs significantly in its course from the desmoid of the abdominal wall. It has a pronounced ability to infiltrate the surrounding tissues, there are frequent cases of tumor spread to the vessels and nerves. The disease usually affects soft tissues. Extra-abdominal desmoids often occur in the area of ​​the shoulder, chest wall, back, and scapula [1, 6]. Desmoplastic bone fibromas are extremely rare. So, R. Buhm et al. [5] described two cases of this tumor affecting the tibia. According to their data, by 1996 only a few dozen cases of bone lesions were presented in the literature. N.P. Petrovichev [3] described the case of femoral desmoid. In the book by S.T. Zatsepin "Saved surgery for bone tumors" [2] reports on operations on the forearm in two patients with recurrence of desmoplastic fibroma. Surgical interventions were accompanied by resection of the bones of the forearm. The observations are interesting, but in neither case are there any clinical or radiological data that could indicate damage to the bones of the forearm by desmoid, and the author himself does not indicate this. We did not find other publications on desmoplastic bone fibroma in the domestic literature. According to N.N. Petrovichev with reference to the work of H.J. Spjut, published in 1971, only 6 cases of femoral injury were described in the literature by that time.
