Introduction. Lymphangioma (lymphatic malformation) is a congenital malformation of lymphatic vessels. According to the classification of the International Society for the Study of the Vascular Anomalies, there are macrocystic, microcystic and mixed types of lymphatic malformations. The typical location of the lymphangiomas is the area of large lymphatic collectors (head, neck, axillary areas), while the scrotum is not frequently affected.
Aim. To present a rare clinical case of lymphatic malformation of the scrotum with successful minimally invasive treatment (sclerotherapy).
Materials and methods. A clinical observation of a 12-year-old child with a diagnosis of «Lymphatic malformation of the scrotum» is presented. From the age of 4, there was a large lesion in the left half of the scrotum. In other clinic, a surgical removal with a diagnosis of «left-sided inguinal hernia», «spermatic cord hydrocele», «isolated left-sided hydrocele» was performed. However, there was a recurrence after the procedure. When contacting the Clinic of pediatrics and pediatric surgery, scrotal lymphangioma was suspected. The diagnosis was confirmed by magnetic resonance imaging. The patient underwent minimally invasive sclerotherapy using the drug «Haemoblock». After 6 months of follow-up, no relapse was seen.
Conclusion. Lymphangioma (lymphatic malformation) of the scrotum is a rare urological pathology that requires specific diagnosis, in-depth differential diagnosis and treatment by a multidisciplinary team of doctors, including a specialist in the treatment of vascular pathology.
