Lichenoid granulomatous dermatitis as a tuberculid in association with spondylitis due to Mycobacterium tuberculosis.
Sarah WilliamsonJena AuerbachKiran MotaparthiPublished in: Journal of cutaneous pathology (2020)
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.
