Structural analysis of gubernaculum testis in cryptorchid patients submitted to treatment with human chorionic gonadotrophin.
OBJECTIVES To make a histological and stereological analysis of gubernaculum testis elastic system fibers, collagen and striated muscle cells in patients with cryptorchidism treated with human chorionic gonadotrophin (hCG). MATERIALS AND METHODS Gubernacula tissue samples were obtained from 12 patients with cryptorchidism. Patients' ages ranged from 1 to 3 years (mean 1.8). Of the 12 patients...
متن کاملImpaired estrogen production by Leydig cells of the naturally retained testis in unilaterally cryptorchid boars and stallions.
Estrogen production in vitro was compared for Leydig cells from cryptorchid and scrotal testes in boars and stallions. Animals with natural and experimental cryptorchidism were used. Purified Leydig cells were prepared from testes of mature animals by collagenase treatment and Percoll density gradients. After incubation for 3 hours (1 X 10(6) cells), estrone sulfate and estrone in the media wer...
متن کاملEmbryonal Carcinoma in Cryptorchid Abdominal Testis of an Infant
Cryptorchidism is a known predisposing factor for the development of testicular tumors in adults. Age of patient at the time of treatment of undescended testes has some bearing on the risk of neoplasia. Testicular neoplasia at the time of primary surgery for cryptorchidism has been reported rarely in prepubertal period. We report a case where embryonal carcinoma was detected in a cryptorchid te...
متن کاملRecurrence of acute myeloid leukemia in cryptorchid testis: case report
A 23-year-old male with a history of bone marrow transplant for acute myeloid leukemia. He presented a large mass in the right inguinal region 5 years ago. Upon physical examination, right-sided cryptorchidism was observed. The tumor markers alpha-fetoprotein and beta-HCG were within normalcy range and lactate dehydrogenase was raised. Computed tomography of the abdomen and pelvis revealed righ...
متن کاملHydronephrosis secondary to a seminoma in abdominal cryptorchid testis.
The incidence of testicular cancer in cryptorchidism is 30 to 50 times higher than in general population. We present a case of hydronephrosis caused by a seminoma in an abdominal cryptorchid testis. A 22 years old male presented abdominal and right flank pain, and haematuria. Despite the fact that he could not feel right testis since he was 7 years old, he had never looked for treatment. A huge...
