This case report highlights the importance of a wide differential diagnosis in transgender patients. A 77-year-old transgender (female-to-male) with recurrent urinary tract infections (UTI) and obstructive voiding difficulties presented with a perineal cyst. Further examinations, including computed tomography (CT) and puncture, revealed that the patient had a symptomatic Bartholin gland cyst, a phenomenon that normally only affects women. In his gender confirmation surgery (GCS) 30 years before, the patient's female labia minora and Bartholin glands were used to lengthen the urethra for the phalloplasty. This explains the unusual location and the prolonged time to the correct diagnose. We decided to perform an incision of the fluid collection from perineal. A follow-up sonography after one month revealed a remaining cyst size of 6 mL, which was assumed to be residual fluid or newly produced liquid; however, the patient has not had any UTIs since the incision of the cyst. Our case seems to be the first description of a symptomatic Bartholin gland cyst in a trans man. This stresses the importance of an expanded understanding of sex/gender concepts, and underlines one of the many possible diagnostic pitfalls when treating trans people.
