Vulvar ulcerative cutaneous tuberculosis secondary to genital tract tuberculosis

Tuberculosis is a chronic infectious disease that gradually poses a certain threat to public health and economic growth. Tuberculosis typically affects the lungs, pleura, and lymph nodes and rarely the skin. Cutaneous tuberculosis manifesting as ulcerated lesions is also rare and often misdiagnosed and missed by clinicians. Here, the authors report a 29-year-old female patient presenting a vulvar ulcer for 10 months, accompanied by irregular menstruation and increased vaginal secretions. After a skin biopsy and endometrial PCR testing, it was finally diagnosed as vulvar ulcerative cutaneous tuberculosis secondary to genital tuberculosis. Anti-tuberculosis treatment was effective. Cutaneous tuberculosis is called a great imitator. In order to facilitate the diagnosis and treatment of tuberculosis by clinicians, the authors systematically reviewed this disease as well.
