Gonococcal tysonitis, a rare local complication of gonorrhea: a clinical study of 15 cases.

To investigate the incidence, clinical manifestations, and treatments of gonococcal tysonitis in men. We enrolled men with gonococcal tysonitis and men with gonococcal urethritis from January 2000 to December 2020. Demographic data, interval from non-marital sexual contact to the onset of symptoms of gonococcal tysonitis, occurrence sites, and manifestations were recorded for all patients. Ceftriaxone (1 g) was injected intramuscularly once daily for 5 days in patients with lesions comprising abscesses or nodules. A single dose of ceftriaxone (1 g) was injected intramuscularly in patients with sinus-like lesions. Incision and drainage were performed in patients with non-ruptured abscesses. Fifteen patients with gonococcal tysonitis (0.29%; 95% confidence interval: 0.15–0.44%) were observed among 5087 patients with gonococcal urethritis. The mean age was 38.64 years (range, 17–74 years). The mean gonococcal tysonitis incubation period was 6.02 ± 1.37 days (range, 2–11 days). Lesions were present in the right side of the preputial frenulum in seven patients (46.67%), in the left side of the preputial frenulum in six patients (40%), and in both sides of preputial frenulum in two patients (13.33%). The lesions manifested as abscesses in 7 patients (46.67%), nodules in six patients (40%), and sinus-like lesions in two patients (13.33%); all lesions exhibited tenderness. All 15 patients were cured after treatment. Gonococcal tysonitis is a rare local complication of gonorrhea. Gonococcal urethritis with concurrent gonococcal tysonitis was less common than gonococcal urethritis with concurrent paraurethral gonococcal infection or gonococcal urethritis with concurrent gonococcal epididymitis. Gonococcal tysonitis lesions manifest as abscesses, nodules, and sinus-like lesions. Treatment with ceftriaxone is effective for gonococcal tysonitis. [ABSTRACT FROM AUTHOR]
