Vulvar Lymphangiectasia After Therapy for Cervical Cancer: A Case Report and Literature Review

Background: Vulvar lymphangiectasia (VLA) is a rare condition characterized by the abnormal dilation of lymphatic vessels in the vulvar region, often secondary to surgery or radiation therapy for malignancies. Its clinical presentation closely resembles other dermatological conditions, posing challenges for accurate diagnosis and appropriate management. This study aims to present a rare case of VLA occurring decades after cervical carcinoma surgery, contributing to the limited literature on this condition and offering insights into its differential diagnosis and management. Methods: A 70-year-old female patient presented with multiple fluid-filled vesicles in the vulvar region appearing 36 years after undergoing radical hysterectomy with pelvic lymphadenectomy for cervical carcinoma. The lesions were biopsied, and histopathological and immunohistochemical analyses were performed to confirm the diagnosis. A review of the existing literature on VLA was conducted to contextualize this case. Results: A histopathological examination revealed papillomatous lesions with hyper-keratosis, dilated lymphatic vessels, and no signs of atypia, consistent with VLA. An immunohistochemical analysis confirmed the lymphatic nature of the lesions. Due to the patient's comorbidities, asymptomatic presentation, and lesion stability, conservative management with regular follow-up was chosen. No progression or complications were observed during the 12-month follow-up period. Conclusions: This case highlights the importance of considering VLA in patients presenting with vulvar vesicles, especially those with a history of lymphatic disruption. An accurate diagnosis through histopathological and immunohistochemical techniques is essential to distinguish VLA from other conditions. Conservative management may be appropriate for asymptomatic cases, but tailored therapeutic strategies are needed to address symptomatic or disfiguring lesions.
