Diagnostic Serendipity - A Rare Case Report Of Vulvar Myoma Masquerading As Bartholin’s Cyst

Objective: To present a case of vulvar myoma which was initially diagnosed as Bartholin’s cyst and to learn the differentiating factors between vulvar myoma and Bartholin's cyst. Case report: A 30-year-old woman presented with a swelling over the right labia majora. Pelvic examination  showed swelling and redness of the right labia majora. A 5x4 cm swelling with cystic consistency was found near the right labia majora. There was no inguinal lymphadenopathy. Bartholin's cyst was suggested and oral doxycycline 100mg bd , metronidazole 400mg tds, pantoprazole 40mg bd was prescribed for 1 week, but no improvement was seen. Therefore, she underwent excision of the swelling. Pathology revealed it to be a benign vulvar myoma. The patient recovered well, and no recurrence was noted after 6 months of follow-up. Conclusion: Vulvar myoma is rare. Sexual history, firm consistency, and imaging are helpful, but the final diagnosis of vulvar myoma is usually made following surgical excision and histopathological analysis.
