This work reports the incidence and structure of testicular appendices (TAs) in patients with cryptorchidism, comparing their incidence with epididymal anomalies and patency of the vaginal process. We studied 55 patients (72 testes) with cryptorchidism and 8 testes as controls (6 with hydroceles and 2 with torsion). We analyzed the relations among the testis, epididymis and patency of the vaginal process and prevalence and histology of the TAs. Smooth muscle cells (SMCs), connective tissue (CT) and elastic system fibers (ESFs) were studied by histochemical and immunolabeling methods. Of the 72 testes with cryptorchidism, 20 (27.77%) presented epididymal anomalies, 41 (56.9%) had patent vaginal processes and 44 (61.1%) had TAs. Of the 44 testes with cryptorchidism and appendices, 30 (68.18%) presented patent vaginal processes and 11 (25%) presented epididymal anomalies. There was no apparent alteration of the epithelium in the appendices of patients with cryptorchidism and in the control group. Stereological analysis documented the prevalence of ESFs (mean of 1.48%), prevalence of veins (mean of 10.11%) and decrease (p=0.14) of SMCs in the TAs of patients with cryptorchidism (mean = 4.93%). Collagen III prevailed in the TAs of patients with cryptorchidism. There was no alteration in the incidence of anatomical anomalies associated with the testes with TAs. The testicular appendices presented significant structural alteration in the patients with cryptorchidism, indicating that TAs present a significant structural remodeling in patients with cryptorchidism.
