1/39. Papillary serous carcinoma of the tunica vaginalis testis.This is a case report of a testicular papillary serous carcinoma of ovarian type (PSCOT) diagnosed in a 50-year-old man. The tumor presented in the form of multiple papillary exophytic excrescencies on the visceral tunica vaginalis testis lining the inner surface of a hydrocele sac. The tumor was histologically a papillary serous carcinoma with numerous psammoma bodies, indistinguishable from similar tumors arising on the surface of the ovary. Following the tumor's surgical removal, the patient was treated with the same drugs used to treat ovarian serous carcinomas, and he is alive two years after the initial diagnosis. PSCOT must be distinguished from mesothelioma of the tunica vaginalis testis, a tumor with a most unfavorable prognosis. As shown here, immunohistochemical findings can be useful for formulating the correct diagnosis of PSCOT.- - - - - - - - - - ranking = 1keywords = testis (Clic here for more details about this article) |
2/39. Metastatic tumour of the tunica vaginalis testis from carcinoma of the stomach.A 50-year-old man with advanced inoperable gastric adenocarcinoma and diffuse peritoneal metastasis received six cycles of palliative chemotherapy and responded clinically with weight gain. Two months after the completion of chemotherapy, however, he developed a left hydrocele. Aspiration yielded 70 ml of yellowish hydrocele fluid, which contained metastatic adenocarcinoma cells, consistent with a gastric primary tumour. A diagnosis of malignant hydrocele was made. Two weeks later, he developed a painful recurrent left hydrocele with increasing pain and swelling. Left orchidectomy was performed. Tiny white mural nodules measuring 1 mm in size were noted on the tunica vaginalis. No focal lesion was noted in the testis. On microscopic examination, the tunica vaginalis showed reactive mesothelial hyperplasia and extensive lymphatic permeation by poorly differentiated adenocarcinoma, consistent with a gastric primary tumour.- - - - - - - - - - ranking = 0.83333333333333keywords = testis (Clic here for more details about this article) |
3/39. Primary testicular plasmacytoma with hydrocele of the testis.A case of primary testicular plasmacytoma complicated with hydrocele of the testis is reported. An 86-year-old man presented with hydrocele of the right testis. High inguinal orchiectomy was performed as the preoperative aspiration cytology of the hydrocele fluid showed atypical cells. Immunohistochemical study of the right testis revealed testicular plasmacytoma positive for IgG. He remained well 9 months after the orchiectomy. This is the second reported case where the preoperative diagnosis of testicular plasmacytoma was made based on the hydrocele fluid cytology.- - - - - - - - - - ranking = 1.1666666666667keywords = testis (Clic here for more details about this article) |
4/39. Prenatal testicular torsion: sonographic appearance in the newborn infant.The prenatal diagnosis of spermatic cord torsion is often really difficult and the diagnosis is usually retrospective. Herein, we report a case of a male newborn baby who presented at delivery with an enlarged, swollen and tender scrotum. US showed an enlarged right testis, with dishomogeneous texture, fluid collection between the testis and the tunica vaginalis and large hydrocele. Differential diagnosis included hydrocele complicated by infection or hemorrhage, testicular tumor or postnatal testicular torsion. color and power Doppler did not reveal any flow signal, and the diagnosis of antenatal torsion with initial necrosis was made. The role of color Doppler US is emphasized in directing the patient to emergency surgical exploration, when testicular salvage may be possible. Delayed surgical treatment can be proposed, when the diagnosis of antenatal torsion has a high degree of certainty. However, the Doppler examination of a newborn baby's testis is a very difficult challenge even for an experienced radiologist.- - - - - - - - - - ranking = 0.5keywords = testis (Clic here for more details about this article) |
5/39. Diagnosis of malignant mesothelioma of the tunica vaginalis testis by ultrasound-guided fine-needle aspiration.Malignant mesothelioma of the tunica vaginalis testis is a very rare tumor that is not usually diagnosed until surgery is undertaken. In only a few cases has the correct diagnosis been obtained preoperatively by cytologic examination of fluid from the hydrocele. We describe a case of mesothelioma of the tunica vaginalis testis that was suspected on sonography because of the presence of a hydrocele and focal nodularities. The diagnosis was confirmed preoperatively by ultrasound-guided fine-needle aspiration cytology aimed at 1 of the focal nodularities. Our patient was an 85-year-old man with concomitant cancer of the sigmoid colon; because of his age and the spread of his colon cancer, we did not remove the scrotal lesion. We recommend consideration of ultrasound-guided fine-needle aspiration cytology of the solid masses instead of the fluid from the hydrocele in cases of suspected malignant mesothelioma of the tunica vaginalis testis.- - - - - - - - - - ranking = 1.1667037214284keywords = testis, cancer (Clic here for more details about this article) |
6/39. Malignant mesothelioma of tunica vaginalis testis associated with long-lasting hydrocele: could hydrocele be an etiological factor?A case of malign mesothelioma of tunica vaginalis testis in a 67 year old man with a 30 year history of hydrocele was reported. The diagnosis was made with an excisional biopsy performed in scrotal exploration and revealed epithelial type mesothelioma. High orchiectomy with hemiscrotectomy was performed. The patient had a local recurrence at the end of two years. As there were no distant metastasis only local excision was performed. In his sixth month after the second surgery he is still tumor free.

7/39. MRI and MRA of a giant hydrocoele in an infant.We present a 7-month-old boy with a giant abdominoscrotal hydrocoele associated with right leg oedema. US revealed an abdominoscrotal fluid-filled mass with a normal testis in the scrotum. MRI allowed precise delineation of the mass while MRA sequences showed extrinsic compression of the right iliac vein and its patency. Hydrocoelectomy and laparotomy were performed and confirmed the diagnosis. US followed by MRI are often necessary to diagnose and delineate giant hydrocoeles. MRA is a non-invasive elegant tool for the detection of vascular complications.- - - - - - - - - - ranking = 0.16666666666667keywords = testis (Clic here for more details about this article) |
8/39. Infantile scrotal pyocele simulating missed testicular torsion on sonography.We present the case of a neonate with idiopathic infantile pyocele. Scrotal sonography revealed a complex fluid collection within the left scrotal sac containing septations and a fluid-fluid level. The dependent region of the collection had moderate echogenicity, the slightly hypoechoic testis was not well defined, and the scrotal wall was thickened. color Doppler sonography revealed mild hypervascularity in the thickened scrotal wall but no vascularity inside the testis. The sonographic findings suggested missed testicular torsion, but surgery revealed a pyocele, for which no source was identified. Radiologists should be aware that idiopathic infantile pyocele can mimic the Doppler sonographic findings in missed testicular torsion.- - - - - - - - - - ranking = 0.33333333333333keywords = testis (Clic here for more details about this article) |
9/39. Diffuse fibrous pseudotumor of the testicular tunics associated with an inflamed hydrocele.Fibrous pseudotumors of the testicular tunics and paratesticular soft tissue are uncommon lesions. They typically arise as painless scrotal masses that may be associated with a hydrocele or history of trauma or infection. Although these lesions are clinically worrisome for a malignant neoplasm, they are thought to be reactive in nature, since they are composed of dense fibrous tissue with interspersed bland fibroblasts and myofibroblasts and mixed inflammatory cells. Once excised, these lesions behave in a benign fashion. Typically, these masses are multinodular, but in rare cases they are diffuse, bandlike myofibroblastic proliferations that encase the testis and are termed fibromatous periorchitis. Herein, we describe a 57-year-old man with a diffuse fibrous pseudotumor/fibromatous periorchitis that encased the left testis and adnexa and arose in close apposition to an inflamed hydrocele.- - - - - - - - - - ranking = 0.33335089659888keywords = testis, neoplasm (Clic here for more details about this article) |
10/39. Well differentiated (benign) papillary mesothelioma of the tunica vaginalis.An unusual mesothelial lesion occurred in the tunica vaginalis of the testis. It conformed histologically and immunohistochemically to well differentiated papillary mesothelioma of the peritoneum. Its aetiology remains uncertain, but this lesion, more than likely, is innocuous. It is important to recognise this entity, which is not well documented in the tunica vaginalis, because it may be misdiagnosed as a malignant mesothelioma and the patient may be subjected to unnecessary treatment.- - - - - - - - - - ranking = 0.16666666666667keywords = testis (Clic here for more details about this article) |
