Lymphangioma Circumscriptum Managed by Intralesional Radiofrequency Ablation: A Case Report

Lymphangioma circumscriptum is a benign lymphatic tumor resulting from a malformation in the lymphatic vasculature during the embryonic period, which can present most commonly over the neck or upper trunk. Here, we present a case of a 22-year-old male who came with complaints of multiple grouped papules and fluid-filled vesicles over the right axilla and the right side of the chest since birth. Biopsy and MRI confirmed the clinical diagnosis of lymphangioma circumscriptum. Initially, surgical excision was attempted as a curative option; however, recurrent lesions were observed, prompting consideration of intralesional radiofrequency ablation using the Megasurg Derma India radiofrequency device (Derma India, Chennai, India) as an alternative approach. Four sessions of intralesional radiofrequency ablation were completed. After completion of the sessions, topical 1% sirolimus ointment application was started to prevent recurrence. An excellent response with a 75% reduction in the number of lesions was observed with minimal recurrence. Hence, intralesional radiofrequency ablation may offer a more effective alternative to conventional surgical intervention.
