| Abstrakt | | Diagnosis of lymphangioma circumscriptum was made in a 21-year-old patient with several, clearly demarcated skin lesions, with the diameter of 2 - 8 mm, on scrotum, penis and pubic area as well as on upper medial parts of thighs. Skin alterations appeared clinically as warty lesions and vesicles. The first skin changes appeared when he was 17. When he was 5, he was submitted to the surgery for bilateral cryptorchidism. There was a sporadic outflow of transparent liquid in the affected areas. Histopathological examination showed dilated lymph vessels in papillary and reticular dermis. In some segments the dilated lymphatics extended to the epidermis that was atrophic in these areas. Radioisotopic lymphography of the affected area revealed a superficial lymphedema where the outtlow was extremely slowed down. A communication between skin lesions and lymphatic vessels of pelvic and inguinal area was noticed. Lymphangioma circumscriptum shows highest incidence in infancy, usually it is present by the age of 5, but it may appear in adolescence and adult life. However, acquired lymphangiomas appear years after the occurrence of predisposing factors, such as surgical procedures, keloids, infections, scleroderma and radiotherapy. The question to which extent the operation of cryptorchidism played a role in the pathogenesis of lymphangioma in our patient remains open. The patient left the hospital immediately after the diagnostic procedures were done.
