The abdominal type of cryptorchism was modeled on random-bred albino rats by replacing both testes from the scrotum into the abdominal cavity for 3 weeks; thereupon they were manipulated into the scrotum. In control rats, no additional surgery was performed. In experimental rats, the testicular
A case of mesothelioma of the right tunica vaginalis testis in a 32-year-old man is reported. Trans-scrotal ultrasonography revealed hydrocele and multiple nodular masses measuring 1.0-4.5 cm in size attached to the parietal vaginal layer. Magnetic resonance imaging demonstrated more clearly nodular
The case of a 63-year-old man with malignant mesothelioma of the tunica vaginalis testis confirmed by electron microscopy is presented. The tumor recurred in the scrotal skin and subsequently metastasized to the inguinal and retroperitoneal lymph nodes. Four and a half years after the original
A 62-year-old man with advanced gastric cancer was admitted with a swelling of the left scrotum. He had undergone subtotal and total gastrectomies 10 and 5 years earlier, respectively. A hard mass was palpated along the left spermatic cord associated with hydrocele testis. A left high orhiectomy was
Benign multicystic mesothelioma is an extremely rare neoplasm usually arising from the visceral mesothelium of the peritoneal cavity typically presenting in young to middle-aged women. It has been deemed an indolent tumour with a possible heritable nature, but also a possible reactive neoplasm
OBJECTIVE
The communicating hydrocele is caused by the failure of the processus vaginalis closure. After the patent processus vaginalis is closed, the hydrocele can subside spontaneously, but the mechanism responsible for the drainage of hydrocele has not been expounded. Former studies showed that
A seven-month-old purebred Nelore calf was diagnosed with a bilateral finger-shaped swelling although more prominent at the left side of the scrotum, located longitudinal and parallel to epididymis corpus. The finding was present from 7 months of age up to castration (performed at 25 months of age).
Lymphatic stomata are small openings of lymphatic capillaries on the surface of the mesothelium that lines the serous cavity and have the function of active absorption. They play an important role in physiological and pathological conditions. The cavity of the tunica vaginalis is a typical serous
Malignant pleural mesotheliomas are rare malignancies associated with asbestos exposure and these tumors are infamous for their poor prognosis. Mesotheliomas in other body areas are much rarer. They may occur in the abdominal cavity and also in the inguinal region. In the latter area they are
The tunica vaginalis is an embryologically derived mesothelium-lined outpouching of the peritoneal cavity, which may develop neoplastic mesothelial proliferations similar to, although much less commonly than, pleural or peritoneal surfaces. We herein report our experience with 12 cases of florid
The transcriptional programs that regulate blood vessel formation are largely unknown. In this paper, we examine the role of the zinc finger transcription factor LKLF in murine blood vessel morphogenesis and homeostasis. By in situ hybridization and immunohistochemistry, we show that LKLF is
A 12-year-old Scottish terrier had a scrotal mass which was diagnosed as a malignant mesothelioma of the tunica vaginalis. The tumour resulted in a rapidly fatal clinical course with direct extension into the peritoneal cavity via the inguinal canal; there were no haematogenous or lymphatic
