Lymphography of the Skin of the Scrotum and of the Penis in a Case of Lymphangioma circumscriptum cysticum

Abstract

The skin of the scrotum possesses a surprisingly dense network of subepidermal
lymphatics (2) which probably serves the function of thermoregulation of this organ.
The lymph drainage of the skin of the penis and of the scrotum flows to the homolateral
and also to the contralateral lymphonodi inguinales sup. superficiales, and then continues
on to the lymphonodi iliaci externi mediales (3, 4).
Circumscribed lymphangioma is a benign tumor of the skin lymphatics, present at
birth or since early childhood at a specific location; its grouping to the skin naevi is under
discussion (5).
Histological examination reveals cystically dilated lymph vessels and lymph channels
of various sizes in the corium, the larger epidermis-covered cysts bulging tumor-like
above the surface of the skin. This clinical picture can be complicated by the great
mechanical friability of the cysts, by lymphorrhea, by phlegmonous changes.
