Tuberculosis of the Cuboid: A Case Report.

Tuberculosis (TB) is a major global health concern, with skeletal TB representing a small fraction of total cases. Foot involvement is relatively uncommon in skeletal TB, and infections of the cuboid bone are especially rare. This case report describes an 18-year-old male who presented with pain and swelling in the dorsolateral left midfoot. A CT-guided biopsy and histopathological examination confirmed necrotizing granulomatous inflammation due to Mycobacterium tuberculosis. The patient was treated with a six-month course of anti-tubercular therapy (ATT) and strict non-weight-bearing protocols, leading to significant symptom improvement. This report emphasizes the importance of histopathological confirmation in diagnosing rare forms of TB and supports existing treatment protocols.
