RESUMO
Causes of cervical ulceration include infection, collagen disease, malignant tumors and external stimuli. Cervical ulceration during pregnancy is rare. We present a case of cervical ulceration caused by group C streptococcal infection during pregnancy. A 36-year-old woman (gravida 1, para 0) complained of metrorrhagia, and a circular cervical ulcer of about 1.5 cm in diameter was detected on her cervix at 37 weeks' gestation. A biopsy and a cultivation test of the ulcer were performed, and pathological diagnosis was made as suppurative inflammation, and group C streptococcal infection was detected by the cultivation test. The ulcer had expanded to about 3 cm in diameter at the onset of labor at 40 weeks' gestation. An emergency cesarean section was performed because of failed induction of labor, and she was delivered of a male baby. The ulcer became gradually smaller after delivery, and completely disappeared on the 35th day after delivery.
