Chronic Tuberculous Osteomyelitis of Cuboid: A Case Report

Introduction: Tuberculous (TB) osteomyelitis of the foot is a rare entity, often leading to diagnostic challenges due to its atypical presentation and similarity to other foot pathologies.

Case report: A 19-year-old male presented with persistent pain and discharge in the left foot for 9 months. Despite previous incision and drainage, the condition progressed. Clinical examination revealed a 1 × 1 cm swelling with indurated margins and a discharging sinus. Diagnostic imaging suggested osteomyelitis, confirmed as TB in nature through histopathological examination, revealing caseous necrosis and langerhans giant cells.

Conclusion: This case illustrates the importance of considering TB osteomyelitis in differential diagnoses of chronic foot lesions and highlights the effectiveness of combined surgical and medical management.
