Glandular inclusions in inguinal hernial sacs and spermatic cords. Müllerian-like remnants confused with functional reproductive structures.
Small, glandular inclusions are present in approximately 6% of hernial sacs from prepubertal males. Identical structures may be present in the spermatic cord. Histologically, these are composed of ciliated, low columnar epithelium with eosinophilic cytoplasm and basal nuclei. A mantle of fibrous tissue surrounds each gland-like structure. These epithelial inclusions may be confused with reproductive ducts of functional importance; however, specific histologic features allow ready distinction. The origin of these structures is uncertain, but it is most probable that they are remnants of Müllerian ducts.
