Osteoid osteoma of the sesamoid bone: An unusual localization

Abstract

Osteoid osteoma is the most common benign bone tumor because it accounts for 10e12% of all these tumors. Localized most often with long bones (75% of cases), especially in the tibia and femur, osteoid osteoma can evoke other etiologies, especially when it is juxta-articular. We report the case of an osteoid osteoma of the sesamoid in a 23-year-old patient with no particular history who presented pain at the root of his hallux evolving for 6 months. The clinical examination was without abnormalities. Standard Xrays found no lesions. The tomodensitometry of the foot showed an image "cockade" with a peripheral sclera ring. The patient underwent surgical excision with simple operative follow-up and disappearance of pain at one year of follow-up. The histopathological study confirmed the diagnosis. The osteoid osteoma of the sesamoid bone is exceptional. The diagnosis may be delayed due to misleading "articular" symptomatology.

Osteoid Osteoma of the Proximal Phalanx of the Great Toe in a 13-Year-Old Female Patient

“…Table 1 summarizes the available literature on OOs occurring in the great toe in a chronological order, where its primary treatment modality was surgical excision in all cases. 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 In addition to surgical excision of the OO, radiofrequency ablation (RFA) has shown clinically equivalent treatment results with advantages of a minimally invasive procedure, negligible postprocedural complications, low recurrence rates, and a shorter recovery time. 23 Intraoperative navigation-assisted or CT-assisted RFA is also an excellent noninvasive modality to accurately localize and ablate medullary OOs.…”
