## Abstract

Small bone involvement caused by Mycobacterium tuberculosis infection is an uncommon clinical entity. Usually, the condition is linked to the spread of bacteria from the lungs. It is rather uncommon for people without pulmonary seeding, trauma, or a history of tuberculosis to experience isolated episodes of spina ventosa. We describe a rare case of an immunocompetent Indian woman, aged 25, who complained of swelling in her left thumb. The diagnosis of primary tubercular dactylitis of the thumb was made after a thorough clinical and laboratory workup, and she received conservative treatment.
