Two Cases of Lymphangioma in Genitourinary System / 대한비뇨기과학회지

ABSTRACT

Lymphangiomas are uncommon tumors that are believed to result from abnormal communication between large dermal lymphatic channels and central lymphatic system. Predilection sites are the chest, neck, axilla, buttock and thigh but may occur on almost any area of skin. Retroperitoneum is very uncommon site of lymphangiomas. They show the highest incidence of onset in infancy, the majority are present by age 5 years. Three types are distinguishable 1) superficial lymphangioma circumscriptum and 2) deep lymphangioma cavernosum and 3) cystic lymphangioma (hygroma). We report two cases of cavernosal type of lymphangiomas with asymptomatic abdominal mass in 4-year-old female and perineal mass in 2l-year-old male patient.
