Acquired Lymphangioma Circumscriptum of the Scrotum: A Case Report

Abstract

Lymphangioma circumscriptum (LC) is an uncommon malformation affecting the skin and subcutaneous tissue. This report documents a case of LC that developed in the scrotum of a 35-year-old male. Upon examination, numerous clusters of clear vesicles were found on the scrotum's surface. The patient had no previous exposure to infections, trauma, surgery, or radiation treatment. A skin biopsy revealed enlarged lymphatic channels in the dermis, aligning with a diagnosis of LC. The patient was treated with cryotherapy using liquid nitrogen, specifically targeting the translucent yellowish vesicles. The cryotherapy was administered in a series of eight sessions, each involving double freeze-thaw cycles, spaced out at two-week intervals. Following treatment, the patient's lesions regressed, indicating a favorable therapeutic outcome. The patient was followed up for nearly one year, during which no new lesions developed, suggesting the treatment's effectiveness in preventing recurrence. The complete resolution of lesions and absence of recurrence during follow-up indicate a good prognosis and successful response to cryotherapy. Scrotal LC, particularly the acquired form in adults without any precipitating factors, is extremely rare. This case underlines the need to include acquired LC in the diagnostic considerations when adult patients present with vesicular lesions on the scrotum, to ensure accurate diagnosis and subsequent proper treatment.
