El linfangioma cavernoso de los genitales externos

PURPOSE

Fluctuating tumours of the scrotal and penile basis can be caused by benign lymphangiomas. These rare malformations can preferently be seen in children.

CASE REPORT

We report about a 10 year old boy, who was presented in our department with a bluish, indolent, 4x2 cm sized, fluctuating tumor of the scrotum and penile basis. Magnetic resonance imaging could demonstrate the whole anatomic extension of the sonographically hypoechoic lesion. Operative removal of the tumour was performed without complication. Histologically, the specimen was diagnosed as cavernous lymphangioma. To date, there is no sign of recurrence (follow-up period: 6 months).

CONCLUSION

A cavernous lymphangioma of the scrotum or penis is very uncommon. We report, to the best of our knowledge, the 2nd case reported in literature. Even lymphangiomas with other histological features rarely affect this region. Lymphangiomas are benign tumours of lymphatic vessels. The surrounding tissue sometimes shows a perifocal inflammation and scarification. About 50% of the cases are considered congenital. 9/10 lymphangiomas become obvious during the first 2 postnatal years. Therapy of choice is the complete excision.

Surgical management of penoscrotal lymphangioma circumscriptum

Lymphangioma circumscriptum of the penis and scrotum is an unusual entity that may be indistinguishable from genital warts. After confirmation of the diagnosis, a treatment plan consisting of wide excision should be outlined. To lower the chance of recurrence, not only the affected skin but all the subjacent subcutaneous tissue, including the deeper components of the lymphatic malformation just above the deep fascia, should be removed.

Lymphangioma of scrotum

A case of lymphangioma of the scrotum is reported. The presenting symptoms of this unusual tumor are an increase in size of the lesion with tenderness or persistent lymphorrhea. Total surgical excision is the definitive treatment.
