Abstract
Desmoplastic fibroma is a particularly rare, benign but locally aggressive, primary bone tumor. Owing to previously published reports stating high recurrence rates following curettage, the recommended primary treatment for desmoplastic fibroma is a marginal to wide tumor resection. In the current report, the case of an athlete with desmoplastic fibroma of the distal femur who was treated with extended curettage, heat ablation and artificial bone grafting is described. The postoperative course was uneventful and no recurrence has been observed during the 12-year follow-up period. The patient is able to sit on his heels with a straight back, without pain and is able run a complete marathon.
Highlights
Desmoplastic fibroma is a benign bone tumor, which is composed of spindle cells with minimal cytological atypia and abundant collagen production [1] that was initially described by Jaffe in 1958 [2]
Desmoplastic fibroma of the bone is a benign, non‐metastatic, but locally aggressive tumor, which often occurs in adolescents and young adults
Surgical experience is limited owing to the rarity of the disease; desmoplastic fibroma only accounts for ~0.1% of all primary bone tumors [9]
Summary
Desmoplastic fibroma is a benign bone tumor, which is composed of spindle cells with minimal cytological atypia and abundant collagen production [1] that was initially described by Jaffe in 1958 [2]. It is a rare tumor with ~200 cases reported in the English literature to date [3,4]. A standard treatment protocol for desmoplastic fibroma has not been established owing to the rarity of the disease, marginal or wide excision of tumors occurring in large bones is often advocated for the initial treatment due to the high recurrence rates following curettage. Written informed consent was obtained from the patient for publication of this case report and the accompanying images
