[Swelling of the pectoralis muscle revealing isolated muscular tuberculosis]. / Tuméfaction du muscle pectoral révélant une tuberculose musculaire isolée.

Soft tissue tuberculosis is one of the rare forms of extrapulmonary tuberculosis. Furthermore, isolated muscular tuberculosis is exceptional. We here report the original case of a young immunocompetent patient with isolated muscular tuberculosis involving major pectoralis muscle. The diagnosis was mainly based on histology. The patient was successfully treated with anti bacterial therapy only. This rare case study has been combined with a literature review.
