ORPHA:457083Morphological anomaly
Also called SGF
What it is
A rare, non-syndromic visceral malformation characterized by an abnormal, continuous or discontinuous attachment of the spleen to the gonad, epididymis or vas. Continuous type has a direct connection between spleen and the gonad, whereas discontinuous type indicates gonadal tissue fused with an accessory spleen or ectopic spleen tissue without connection to the principal spleen. Males typically present with a scrotal mass or as an incidental finding during the management of cryptorchidism, testicular tumors or inguinal hernia. In females this is usually an incidental finding during laparotomy.

ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
