Delayed presentation of a non-resorbing postpartum vulvar hematoma: A case report

Vulvar hematomas are more common in the obstetric population, and usually present within 24 h of delivery. Small, nonexpanding vulvar hematomas will often resolve with conservative management. In a rural setting in the USA, a 35-year-old woman, G3P3, presented to clinic 26 days after a home vaginal delivery attended by a midwife, which was complicated by postpartum hemorrhage secondary to retained placenta. Ten days after her delivery she developed intense pressure in her inferior right vulva. On examination a 4–5 cm well defined right vulvar mass was observed. Incision and drainage were performed and the mass was determined to be a hematoma that had not resorbed. Four days later, the patient returned to clinic as the mass had reformed. Computerized tomography did not show extravasation of contrast. As examination showed the mass was now 1 cm smaller, no intervention was undertaken and after one month the hematoma had completely resolved. This case provides a rare example of the delayed development of a vulvar hematoma. In the literature, the vast majority are reported to present within 24 h of delivery. Smaller hematomas, such as this one, which was 4-5 cm, are treated conservatively, as they typically absorb. This hematoma was present for approximately two weeks without resorbing. •A 35-year-old parous woman developed a 4–5 cm vulvar hematoma 10 days after a home vaginal delivery attended by a midwife.•She presented approximately two weeks later as the hematoma had not resorbed.•In the literature, the vast majority of vulvar hematomas are reported to develop within 24 h of delivery.
