Ectopic scrotum

Abnormal scrotum position

HP:0030275

What it means

Scrotum in a position other than the usual position inferior to the base of the penis.

This term is distinguished from Accessory scrotum, as there is no significant scrotal tissue in the normal position in ectopic scrotum. This definition excludes the finding of Penoscrotal transposition or Overriding scrotum. Usually the scrotum is split and there is unilateral ectopia. The ectopic scrotum is typically located supra-inguinally, but may be located elsewhere such as on the upper thigh. A testis is commonly present in the ectopic scrotum. Ectopic scrotum can be accompanied by Chordee or Bifid penis, which should be coded separately, and by renal and non-urogenital malformations.
