ABSTRACT

Cutaneous tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis. Nodular tuberculid of the face, also known as Lewandowsky’s rosacea-like tuberculid, is a rare variant of cutaneous tuberculosis, accounting for less than 1% of all cases. We present a 47-year-old immunocompetent male with a dermatosis characterized by papular and some nodular lesions in the central facial region. Initially misdiagnosed as rosacea due to inadequate response to standard treatment, a subsequent histopathological study revealed tuberculoid granuloma formation. This prompted a purified protein derivative (PPD) test, which was positive at 72 hours, confirming the diagnosis of Lewandowsky’s rosacea- like tuberculid. A search for systemic tuberculosis yielded no evidence of extracutaneous involvement. The patient responded favorably to anti-tuberculosis treatment.
