Infection of Tyson's glands is not a common complication of gonorrhoea. Its incidence is not known, and neither the Center for Disease Control of the Public Health Service nor national statistical compilations of diseases can give details. Reports from urological services of university hospitals confirm that it is rare by such remarks as, 'I saw a case six years ago' etc. However, Bavidge (1976) reported two cases of gonococcal tysonitis with urethritis and one case of gonococcal tysonitis without urethritis in 1975 at the Newcastle General Hospital. I have had two cases in Massachusetts during the fiscal year 1976 from a total of 60 000 visits in our venereal diseases clinics. Tyson's glands are a pair of sebaceous glands located near the coronal sulcus, one on either side of the frenum; they produce smegma. When infected with the gonococcus, the glands manifest unilateral or bilateral tender swelling and on moderate pressure, pus may be expressed from ducts opening on either sides of the frenum. Usually the infection responds to antibiotics and the swelling subsides. If not, incision and drainage of the glands will be necessary followed by another course of antibiotics. Patients who also have a tight prepuce should be circumcised to prevent reinfection of these glands, should the patient contract another infection with the gonococcus.
