The accessory navicular bone (ANB) is one of the most common accessory ossicles of the foot. Fewer than 1% of ANBs are symptomatic, and most of the symptomatic ANBs are type II ANBs. Avascular necrosis of the type II ANB is an uncommon cause of symptomatic accessory navicular syndrome and also a rarely reported condition in the podiatric medical literature. This rare disorder must be distinguished from other painful conditions of the ANB and should be considered in differential diagnoses. We present a case of avascular necrosis of the type II ANB with sclerosis on radiographs and magnetic resonance images in a 46-year-old woman.
Osteoid osteoma is a benign tumor originating from osteoblasts, and it is mostly seen in long bones of lower limbs. The distal phalanx of the foot is an atypical location for an osteoid osteoma, and lesions occurring in this location may be a diagnostic challenge. A 22-year-old man presented with a complaint of severe pain on the second distal phalanx of his right foot. An osteoid osteoma was suspected after radiologic evaluation. The lesion was surgically excised and removed completely by curettage. Histopathologic evaluation confirmed the diagnosis of an osteoid osteoma. The patient was followed-up for a 9-month period without any symptoms or recurrence.
An osteochondroma or exostosis is the most common benign bone tumor, and it is commonly localized in the metaphyses of the long tubular bones. Lesions are rarely localized around the ankle. We present a case series with osteochondroma around the ankle. All of the patients presented with a mass around the ankle. In these three cases, the masses were symptomatic, and in one patient it caused a deformity. Osteochondroma was suspected after physical examination and radiologic evaluation. After preoperative work-up, diagnosis, and exhaustion of conservative care, a plan for surgical excision was presented to each patient. Histopathologic evaluations confirmed the diagnosis of osteochondroma. The patients have been discharged without any complications or symptoms during clinical follow-up.
