1/323. Primary carcinoid of testis.A patient with primary solid carcinoid of the testis is described and 8 previous cases are reviewed. Ultrastructural study of our case disclosed pleomorphic granules, typical of the insular type carcinoid of the intestine of midgut derivation. Primary solid testicular carcinoid appears to behave as a benign neoplasms. None of these patients had evidence of metastases or the carcinoid syndrome for periods ranging from 20 months to 25 years.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/323. Mixed testicular tumor in immunosuppressed patient: case report.A 30-year-old man who was maintained on immunosuppressants following renal transplantation had seminoma with teratoma of the right testis 3 months postoperatively. The temporal relationship in the development of the tumor in the presence of immunosuppressants strongly suggests the importance of the immunodefense mechanism in the control, development or growth of the neoplasm.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
3/323. Neuro-ophthalmologic manifestations of a paraneoplastic syndrome and testicular carcinoma.The authors report two patients with testicular cancer who exhibited supranuclear gaze disorders as a manifestation of a paraneoplastic brainstem encephalomyelitis. In the first patient, neuro-ophthalmic dysfunction was accompanied by a prominent limbic encephalitis whereas in the second patient, an unusual, mixed pendular and jerk nystagmus was manifested. neuroimaging revealed an enhancing hypothalamic mass in the first patient and was negative in the second. blood from both patients contained an antibody previously reported in a patient with limbic encephalitis and testicular cancer.- - - - - - - - - - ranking = 0.00054674454975307keywords = brain (Clic here for more details about this article) |
4/323. Primary carcinoid tumor of the testis: immunohistochemical, ultrastructural and dna flow cytometric study of two cases.Primary testicular carcinoid tumor, occupying 0.23% of testicular neoplasm, is a rare and indolent neoplasm with the potential for distant metastasis. We present two cases of primary pure carcinoid tumor of the testis. Both patients were 36 years old. physical examination revealed testicular mass with and without tenderness. The preoperative serum levels of beta-human chorionic gonadotropin and alpha-fetoprotein were normal and neither patient had carcinoid syndrome. The tumors measured 7.5x6x4 cm and 5.5x5x4 cm in size. Histologically, immunohistochemically and ultrastructurally, the tumors showed typical features of the carcinoid tumor. Case 1 showed extensive tumor necrosis and vascular invasion. dna flow cytometric analysis showed aneuploidy with dna index of 1.47 and S G2M of 14.0% in case 1 and tetraploidy with dna index of 1.96 and S G2M of 22.1% in case 2. Both patients have been well without any signs of metastasis after operation for 24 months in case 1 and for 16 months in case 2.- - - - - - - - - - ranking = 2keywords = neoplasm (Clic here for more details about this article) |
5/323. Metastatic testicular teratoma of the nasal cavity: a rare cause of severe intractable epistaxis.Malignant neoplasms of the nasal cavity and paranasal sinuses are uncommon. choriocarcinoma is a highly malignant germ cell tumour occurring in the reproductive organs. Metastasis may be principally by the lymphatic route as in other germ cell tumours but choriocarcinoma is also known to spread haematogenously. We present a rare case of metastatic choriocarcinoma to the nasal cavity from testicular teratoma presenting with intractable epistaxis in a 32-year-old Caucasian male, who ultimately succumbed to this disease.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
6/323. Case of gonadoblastoma in a 9-year-old boy without physical abnormalities.BACKGROUND: A 9-year-old boy was admitted to Jikei University Hospital complaining of gradual enlarging of the left scrotal contents. methods/RESULTS: physical examination was significant for bilateral descended testicles. No abnormalities were detected in the testicles or along the spermatic cords. Scrotal ultrasound showed that hyperechoic shadows were recognized in the central area of the left testicle. Subsequent testicular biopsy and histopathological examination showed intratubular malignant germ cells in the testicular tubules. One week later, left orchiectomy was performed. CONCLUSIONS: Histopathological evaluation revealed gonadoblastoma. gonadoblastoma, a rare gonadal neoplasm, is composed of germ cells and sex cord derivatives and usually occurs in phenotypically female patients with gonadal dysgenesis. To date, only three cases of gonadoblastoma have been reported in anatomically normal male patients with scrotal testicles. We report on a case of gonadoblastoma unaccompanied by a germ cell tumor in a physically normal male.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
7/323. Extramammary Paget's disease with aggressive behavior: a report of two cases.Extramammary Paget's disease (EMPD) is an intraepithelial neoplastic disorder which is included as a rare malignant condition. However, it sometimes shows aggressive behavior of local recurrence and coexisting malignancy. We had experienced nine cases of EMPD involving the scrotum for seven years. Two cases of them presented metastasis. The first case presented extensive inguinal lymph node metastasis with underlying adnexal adenocarcinoma one year after wide local excision. The second case initially presented multiple metastasis to the liver and in the lymph node. The latter, showing fulminant progression with liver metastasis, may be only the second case reported in English literature. EMPD is considered as a malignant neoplasm with aggressive behavior from initial presentation. Because wide local excision of the lesion alone may be occasionally insufficient, a careful follow-up must be done to detect recurrence or internal malignancy.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
8/323. Angiosarcoma of the testis.A primary angiosarcoma of the testis in a 74-year-old patient was a highly anaplastic epthelioid angiosarcoma, which was positive for endothelial markers immunohistochemically. The tumour was unrelated to testicular germ cell neoplasm; the patient had received no previous radiation or chemotherapy.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
9/323. Fine needle aspiration cytology of adenomatoid tumor. A case report.BACKGROUND: adenomatoid tumor is a benign neoplasm of the male and female genital tract. The epididymis is the most common site. CASE: A 25-year-old male presented with a swelling in the left side of the epididymis. Cytology showed monotonous cells arranged in sheets, cords and glandular patterns. The cell showed eccentric vesicular nuclei with fine chromatin and abundant, vacuolated cytoplasm. CONCLUSION: With the help of fine needle aspiration cytology, an accurate diagnosis of adenomatoid tumor is possible and can relieve anxiety and uncertainty in both the patient and physician.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
10/323. Testicular plasmacytoma: appearance on gray-scale and power Doppler sonography.A case of testicular plasmacytoma, a very rare neoplasm, is presented. The gray-scale and power Doppler sonographic findings are illustrated. The lesion appeared as a hypoechoic, intratesticular mass that was markedly hypervascular. When marked hypervascularity is present in a testicular mass in a patient unlikely to have orchitis on clinical grounds, plasmacytoma should be considered in the differential diagnosis.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
