Introduction: Osteoblastoma is a benign tumor which constitutes around 1% of primary bone tumors. The incidence of an osteblastoma of the calcaneum is <0.8% among all.

Case Report: We report a 17-year-old boy who presented with unremitting heel pain of 4 months’ duration associated with a swelling which was clinically and radiologically diagnosed as either an aneurysmal bone cyst or giant-cell tumor. The patient was treated with an extended curettage and cementing of cavity. The final diagnosis of an osteoblastoma of calcaneum was established post-operatively following histopathological examination of biopsy.

Discussion: The prevalence and behavior of calcaneal osteoblastomas are yet to be reported in the Indian population. Lack of clinician familiarity and a rare incidence translate into a delay in the diagnosis of tumors and tumor-like lesions of the calcaneum, as seen in our case. Their recognition is imperative to avoid mistaking the condition for an aneurysmal bone cyst, giant-cell tumor, or even an osteogenic sarcoma and be managed more aggressively than required.

Conclusion: An adolescent presenting with chronic unremitting heel pain should undergo early and detailed radiographic evaluation. A high index of suspicion is needed to diagnose this condition early. Outcome largely depends on early diagnosis and prompt surgical intervention.
