Further studies of intestinal heterotopia in urethral caruncle.

Colonic mucosa-like intestinal heterotopia in a urethral caruncle is reported in a 2 yr 7 mth old girl and three women; 55, 71 and 78 yrs old. The occurrence of the anomaly in a child supports the first two author's earlier suggestion that the condition is congenital in nature. In princip this could also be the case in post-menopausal women, although the possibility of metaplasia must also be considered. Perhaps the condition could be a precursor of some adenocarcinomas of the distal urethra.
