Penile tuberculosis

The incidence of penile tuberculosis accounts for 4% of the incidence of genitourinary tuberculosis. The disease can occur on the surface of the penis skin, in the cavernous body of the penis, or in the penile urethra. Mycobacterium tuberculosis can be transmitted by urinary tuberculosis, and it can also be transmitted through sexual intercourse or exposure to contaminated clothing. Whether it is transmitted by blood is still controversial. After the onset, a little red tuberculosis nodules appeared at the head of the penis, the penis, or the outer mouth of the urethra. Later, the nodules in the center of the nodules became ulcerated, the surrounding tissues became hard, and caseous necrosis appeared at the bottom of the ulcer. Increasingly, the inguinal lymph nodes are enlarged.
