1766upus vulgaris (LV) is the most common, post-primary; highly destructive form of cutaneous tuberculosis in a patient with intact immunity. Women are twice as likely to be affected as men. LV may appear at sites of inoculation, in scrofuloderma scars, after Bacille CalmetteGuerin (BCG) vaccination, or most commonly at distant sites from the initial infectious focus. LV is associated with moderately high immunity to tuberculosis; most patients will have a positive tuberculin test. In approximately 90% of the patients, the head and neck are involved. It usually presents as a solitary lesion. In very rare instances, LV may present with multiple lesions.1-6 Here, we describe a case of multifocal lupus vulgaris.
Multifocal Lupus Vulgaris: Case ReportA AB BS ST TR RA AC CT T Cutaneous tuberculosis is a rare form of extrapulmonary tuberculosis and primarily seen in the developing countries. Lupus vulgaris is a chronic progressive form of cutaneous tuberculosis that occurs in individuals with a moderate to high degree of immunity, and usually presents as a solitary lesion on the head and the neck. In this paper, lupus vulgaris is reported in a 29-yearold woman who had a 7-year history of plaques first beginning on her left arm and then spreading to her trunk, back and left retroauricular area. The diagnosis of lupus vulgaris was based on clinical, histopathological findings and purified protein derivative (PPD) positivity. No acid-fast bacilli were detected by Ziehl-Neelsen staining. Culture of biopsy specimens and polymerase chain reaction were negative for M. tuberculosis. She had antituberculous therapy with three drugs and her lesions responded rapidly to this therapy.
