Verrucous Carcinoma of the Vulva Presenting with Urinary Retention in a Young Female: A Rare Case Report

Verrucous carcinoma of the vulva is a rare, well-differentiated variant of squamous cell carcinoma, characterized by slow growth, local invasiveness, and a low risk of metastasis. It most commonly affects postmenopausal women and is seldom reported in younger individuals. We report a rare case of a 37-year-old Asian woman who presented with a 6-month history of a progressively enlarging exophytic vulvar lesion, associated with foul-smelling discharge and urinary retention. The lesion’s deceptively benign appearance initially mimicked common vulvar conditions, creating a diagnostic dilemma and contributing to delayed diagnosis. Clinical examination revealed a large, friable, cauliflower-like growth on the left vulvar region. Imaging studies, including contrast-enhanced computed tomography and magnetic resonance imaging, confirmed a locally advanced vulvar mass involving adjacent structures. Histopathological examination diagnosed it as verrucous carcinoma, without lymphovascular or perineural invasion. The patient underwent a radical vulvectomy with myocutaneous flap reconstruction. The postoperative recovery was uneventful; however, the patient failed to return for follow-up. This case highlights an uncommon presentation of verrucous vulvar carcinoma in a young woman, emphasizing the importance of early diagnosis and aggressive surgical management to prevent morbidity.
