We report the case of a 50-year-old male with a rare combination: pulmonary tuberculosis and cutaneous leukocytoclastic vasculitis. The
patient sought emergency treatment presenting with headache, arthralgia, cutaneous rash, and weight loss (4 kg) in the last 20 days. A chest
X-ray, performed in a previous outpatient visit, revealed cavitation in the middle and upper lobes of the right lung, as confirmed by computed
tomography. Sputum smear microscopy (Ziehl-Neelsen staining) was positive in three consecutive samples, and the result of the skin lesion
biopsy was consistent with cutaneous leukocytoclastic vasculitis. The patient was therefore diagnosed with cutaneous leukocytoclastic
vasculitis accompanied by pulmonary tuberculosis. Our objective was to describe a combination rarely reported in the medical literature and
to discuss the possible pathogenic mechanisms of this combination.
