Abstract

Failure of the testicle to reach its proper destination in the scrotum is the commonest important anomaly of the spermatic tract. As a rule the improperly descended testicle is located at some point along the normal course of descent (abdominal, inguinal or high scrotal) but in some instances the organ is ectopic or aberrant. The ectopic gland may be (a) interstitial (lying anterior to the aponeurosis of the external oblique muscle), (b) femoral or crural (lying in Scarpa's triangle), (c) penile (overlying the pubic bone), (d) perineal and (e) transverse (fig. 1). In the last instance the two testes descend through the same inguinal canal. The present discussion concerns only perineal ectopia; three instances recently observed in children are reported. ETIOLOGY Incidence.— Perineal testicular ectopy is an unusual observation. Although the reported incidence of improperly descended testicle varies from 1.02 per cent in 108,000 men¹ to 3 per cent
