Giant epidermoid cyst of the vulvo-perineal region during pregnancy

Excerpt

A 27-year-old woman (G-2, P-1) in the 22nd week of pregnancy was admitted with painless vulvo-perineal swelling, which was gradually increasing in size over the previous few weeks. The mass was present during the first year following vaginal delivery and increased in size during pregnancy. Physical examination revealed a subcutaneous, relative mobile, elastic mass in the right vulvo-perianal region with normal overlying skin, measuring approximately 10 × 10 cm (Fig. 1A). Perineal ultrasound demonstrated a well-demarcated oval-shaped mass with internal debris in a surrounding rim and no Doppler flow (Fig. 1B). Under general anesthesia, the patient underwent an en bloc surgical excision of the vulvo-perineal mass together with the overlying skin and followed by primary closure of the wound (Fig. 1C). The histopathologic examination confirmed the diagnosis of epidermoid cyst (Fig. 1D). The remaining antepartum course was uneventful and the patient delivered via caesarean section a healthy baby at 40 weeks of pregnancy. The surgical patient experienced no complications and was asymptomatic with no recurrence at 2 years.
