Lichenoid granulomatous dermatitis (LGD) is a histopathologic pattern with a band‐like lymphocytic infiltrate, typical of lichenoid dermatitis, combined with dermal histiocytes and granulomatous inflammation. Prior reports have described cases of LGD caused by non‐tuberculous mycobacteria, with evidence of intralesional acid‐fast bacilli or mycobacterial DNA. Herein, we report a patient with pulmonary and extrapulmonary Mycobacterium tuberculosis infection who developed LGD. No evidence of M. tuberculosis was detected within the cutaneous lesions, suggesting a potential delayed‐type hypersensitivity reaction to tuberculosis.
