PURPOSE: We report 7 cases of scrotal cystic lymphangioma and review the literature on this unusual lesion, which is often misdiagnosed as other conditions and treated incorrectly. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 7 patients with scrotal cystic lymphangioma treated from 1984 to 1996 at 5 institutions. RESULTS: Mean patient age at presentation was 3 years and painless scrotal swelling was the most common symptom. Physical examination demonstrated an unusual cystic scrotal mass with a normal testis and cord in most patients, and ultrasound in 4 showed a complex septated cystic mass. Preoperative misdiagnosis in all 7 patients included hernia, hydrocele, hematocele, varicocele and possible torsion. In 6 children the lesions were more extensive than expected with deep perineal and/or inguinal involvement, including 2 who also had pelvic and retroperitoneal extension. Incomplete excision led to recurrence in 4 patients. CONCLUSIONS: Scrotal cystic lymphangioma presents as an unusual cystic scrotal mass. Although misdiagnosis has been common, awareness of the characteristic features of this lesion should lead to the correct preoperative diagnosis. When lymphangioma is suspected, imaging of the adjacent inguinal, perineal and pelvic regions should be performed. Complete excision is mandatory to prevent recurrence.
