1/201. life-threatening germ cell tumor arising in cryptorchidism: a case report.We report a case of life-threatening germ cell tumor in abdominal cryptorchidism. A 32-year-old man presented with a three-month history of dyspnea, loss of appetite, general weakness and a large abdominal mass. physical examination revealed vacancy of the right scrotal contents. Chest radiograph showed massive left pleural effusion. Abdominal ultrasound revealed ascites, right hydronephrosis and the presence of an 18 x 15-cm heterogeneous echogenic mass in the upper abdomen and right iliac fossa. Abdominal computerized tomography (CT) revealed the presence of a large heterogeneous tumor and an enlarged (4 x 4-cm) retroperitoneal lymph node. Sonoguided needle biopsy of the abdominal mass demonstrated malignant cells of an uncertain type and origin. serum alpha-fetoprotein (AFP) and beta-human chorionic gonadotropin (beta-HCG) concentrations were elevated. Under the diagnosis of metastatic nonseminomatous germ cell tumor in abdominal cryptorchidism, the patient received three cycles of cisplatin-based combination chemotherapy followed by resection of the abdominal residual cryptorchid tumor. Histologically, the tumor showed marked necrosis without viable cancer. The patient had remained free of disease for seven months following surgery.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
2/201. Long arm deletion of chromosome 10 in a boy with monorchidism.We report on a boy with long-arm deletion of chromosome 10 and compare this case to 10 previously reported patients. He had right cryptorchidism and absence of the left testis, but the size of his penis was normal. cytogenetic analysis of the case showed the deficiency of 10q26.1-26.3 and the presence of 10qter. Four of 10 previously reported patients had an intersex phenotype, and all others had combinations of cryptorchidism, micropenis and hypospadias. These facts indicate that the terminal of chromosome 10q is strongly associated with abnormal male development.- - - - - - - - - - ranking = 3833.138981459keywords = testis (Clic here for more details about this article) |

4/201. seminoma associated with bilateral cryptorchidism in Down's syndrome: a case report.BACKGROUND: A case of testicular typical seminoma associated with bilateral undescended testes in Down's syndrome is reported. A 42-year-old institutionalized male patient developed left testicular seminoma with retroperitoneal metastasis. methods/RESULTS: Neither adjuvant chemotherapy nor radiotherapy were performed due to his severe mental retardation. He died as a result of the cancer 2 years after a left radical orchiectomy and an autopsy was carried out. DISCUSSION: Recently an increase in the incidence of the association of testicular tumors and Down's syndrome has been repeatedly documented. Thirty-six cases of testicular tumors associated with Down's syndrome have been reported and of these 17.1% had cryptorchidism. This is a much lower percentage considering the high risk of cryptorchidism in males with Down's syndrome. The relationship between testicular germ cell tumors associated with cryptorchidism and Down's syndrome is discussed.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
5/201. Testicular adrenal rests: evidence for luteinizing hormone receptors and for distinct types of testicular nodules differing for their autonomization.We report one patient with 21-hydroxylase deficiency and associated bilateral macro-orchidism caused by nodular hyperplasia of testicular adrenal rests (TAR). The boy, referred to us when 10 years old, was born with bilateral cryptorchidism that was treated unsuccessfully with i.m. injections of human chorionic gonadotropin (hCG) and later on with orchidopexy. He was treated with oral dexamethasone (0.625 mg per day) for the following 13 years. After one year, there was a marked reduction in steroid hormone levels (17-hydroxyprogesterone (17-OH P) from 27.2 to 1.2 nmol/l, testosterone from >104 to 4.8 nmol/l, estradiol (E(2)) from 481 to 33 pmol/l). After the same period of time, both testicular volume and nodularity decreased: from 45 to 18 ml and from numerous to four nodules in the right testis, and from 40 to 13 ml and from numerous to three nodules in the left testis. At the third year, there were transient increases in serum gonadotropins, testicular volume (right testis = 25 ml, left testis = 20 ml) and steroid hormones, including cortisol (serum ACTH and dehydroepiandrosterone sulfate remained suppressed). At the fourth year of follow-up, there were still four nodules in the right testis and three in the left testis. The LH-dependency (which implies possession of LH/hCG receptors) of these nodules was also substantiated by their steroidogenic response to an acute i.m. hCG test. An exogenous ACTH stimulation test increased serum 17-OH P and cortisol. Since these nodules, unlike the majority of those present initially, were not suppressed by the corticosteroid therapy and since they were not detected when the patient returned for control at 23 years of age, they had partial autonomy from ACTH. At 23 years of age, the patient had a single nodule in the right testis (right testis volume = 13 ml, left testis volume = 10 ml), which should have accounted for the consistent difference in size between the two gonads. serum LH was about 7 mU/l and FSH about 23 mU/l. The responsiveness of plasma steroid hormones to hCG had changed quantitatively and qualitatively. Secretion of cortisol was absent, secretion of 17-OH P and testosterone was reduced, and secretion of E(2) was much increased. The ACTH stimulation test showed that serum cortisol did not respond, while the other steroids responded in the order of 17-OH P>E(2)> testosterone. We conclude that there were three different groups of TAR when the patient was already 10 years old: (i) ACTH-sensitive (the majority), (ii) partially ACTH-insensitive but LH/hCG-sensitive (three nodules in the left testis and three in the right testis), (iii) almost entirely ACTH-insensitive and partially hCG-insensitive (a single nodule in the right testis). Probably, the never suppressed gonadotropin levels (presumably due to the bilateral testicular damage subsequent to the cryptorchid state) and the hCG therapy were major etiological factors for the appearance of the second and third population of TAR.- - - - - - - - - - ranking = 45997.667777509keywords = testis (Clic here for more details about this article) |
6/201. cryptorchidism as a result of burn injury.Thermal injury of the genitalia usually occurs as part of larger body surface burns. The most common sequelae of burns of the penoscrotal region are contractures of penile shaft, but we did not encounter any reported cases in English literature with cryptorchidism as a sequel of burn injury. A 7 year old boy with cryptorchidism as a component of extensive perineal and inguinal burn deformity is reported to indicate the role of burn injury in cryptorchidism. cryptorchidism as a component of perineal burn injury may be caused by the attachment of the cremaster muscle or fascia to the abdominal wall during the process of wound healing. As healing process of wounds on inguinal region by contraction may cause testis entrapment and cryptorchidism, a careful genital examination bears a great importance in inguinal burn deformities in order not to miss any trapped testis and replace it as early as possible before degenerative changes begin.- - - - - - - - - - ranking = 7666.2779629181keywords = testis (Clic here for more details about this article) |
7/201. Fanconi's anemia with solitary crossed renal ectopia, vesicoureteric reflux, and genital abnormalities.Fanconi's anemia is an autosomal recessive disease, the main feature being pancytopenia secondary to bone-marrow hypoplasia. However, multiple congenital abnormalities may be encountered, urogenital malformations being common. We describe a patient with solitary crossed renal ectopia, vesicoureteric reflux, hypospadias, and unilateral undescended testis with absent vas deferens.- - - - - - - - - - ranking = 3833.138981459keywords = testis (Clic here for more details about this article) |
8/201. Two brothers with distal arthrogryposis, peculiar facial appearance, cleft palate, short stature, hydronephrosis, retentio testis, and normal intelligence: a new type of distal arthrogryposis?We report on two brothers, a 22-month-old boy and a 7-month-old boy, with multiple distal arthrogryposis (DA), peculiar facial appearance, cleft palate, short stature, hydronephrosis, retentio testis, and normal intelligence and karyotypes. The parents were cousins once removed. The combination of the clinical manifestations in the patients and the lack of involvement in their parents are incompatible with any known types of DA, and suggest a new type of DA. The parental consanguinity in the family suggests that the disorder is an autosomal recessive condition, although X-linked inheritance is not ruled out.- - - - - - - - - - ranking = 19165.694907295keywords = testis (Clic here for more details about this article) |
9/201. Congenital spigelian hernia and cryptorchidism: cause or coincidence?Congenital spigelian hernia (SH) is very rare in the pediatric age group. This is a report of two cases of SH in 1-week and 3-month-old male infants. A review of the literature revealed only 35 cases of SH in children younger than 17 years of age, bringing the total including our 2 cases to 37. There were 25 males and 12 females, a ratio of 2.1:1. Their ages ranged from 6 days to 17 years (mean 4.52 years). The hernia was situated on the right side in 13, the left side in 19, and was bilateral in 4. In one case the side of the hernia was not mentioned. In 29 cases the hernia was spontaneous while in 5 it was caused by trauma. In 3 children the hernia developed postoperatively, in 2 following repair of a congenital diaphragmatic hernia and in 1 following excision of a mediastinal neuroblastoma. Two children presented with a strangulated SH. Eleven of the 35 previously reported children had associated conditions; in 5 there was an ipsilateral undescended testis (UDT). Our two infants with SH also had an ipsilateral UDT. The significance of this association is discussed.- - - - - - - - - - ranking = 3833.138981459keywords = testis (Clic here for more details about this article) |
10/201. Two cases of perineal ectopic testis.PURPOSE: Perineal ectopic testis is seen very rarely and here we report on two patients with perineal ectopic testis. methods/RESULTS: We experienced two cases of perineal ectopic testis on which orchiopexies to the corresponding hemiscrotums were performed. CONCLUSIONS: On surgical exploration, the gubernaculum testes were found to lie fixed to the perineum.- - - - - - - - - - ranking = 26831.972870213keywords = testis (Clic here for more details about this article) |
