1/10. Primary carcinoid of the testis associated with carcinoid syndrome.Testicular carcinoid is a rare disease accounting for less than 1% of all testicular neoplasms. It rarely manifests symptoms of carcinoid syndrome. Recent reports have noted that only 1.1-3.1% of testicular carcinoid tumors are complicated by carcinoid syndrome. In general, large tumor size and the presence of carcinoid syndrome are features associated with a malignant course. In the present case, pathological findings revealed pure carcinoid of the testis without metastasis. Moreover, watery diarrhea due to carcinoid syndrome disappeared and the serum serotonin level normalized following orchiectomy. The patient was followed up for 12 months with whole body computed tomography scan and assessment of serotonin levels. To date, there is no evidence of tumor recurrence. These findings suggest that monitoring serum serotonin levels may be useful as a marker during follow up of this type of tumor.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
2/10. Testicular metastasis from squamous cell carcinoma of the lung.We present a case of squamous cell carcinoma of the testis that metastasized from lung cancer. The patient, who had received left pneumonectomy 2 years earlier for squamous cell carcinoma (SCC) of the lung, developed pulmonary metastasis, which was treated with chemotherapy. Although the recurrence regressed after treatment, the testicular tumor progressed gradually. Left radical orchiectomy was performed. Pathological examination revealed metastatic SCC. Testicular metastasis from lung cancer is a very rare disease.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
3/10. Granulocytic sarcoma of the ovotestis: an association of myelodysplastic syndrome and hermaphroditism.Granulocytic sarcomas are extramedullary tumors (EMD) of malignant myeloid precursor cells. EMD or granulocytic sarcoma of ovary is rare disease. A 15-year-old girl had complaints of abdominal pain and weight loss for 3 months. On physical examination, there were hepatosplenomegaly and a painless mass under the umbilicus. breast development was grade II. There was no clitoris hypertrophy. Her labia majora were separate and vagina hypoplastic. Hemoglobin level was 9.3 g/dl, white blood cells count 2.8 x 10(6)/1, platelet count 31.6 x 10(9)/1. There were dysplastic features in the blood and bone marrow cells. There were 10 and 22% blasts in the peripheral blood smear and bone marrow, respectively. The levels of serum follicle stimulating and luteinizing hormones were high. An inguinal mass (diameter 9.5 x 7.6) cm was detected on computed tomography. The histopathological diagnosis of this was obtained from laporascopy was composed of ovotestis and there was marked blastic infiltration in this ovotestis which had myeloid markers on flow cytometry. In the immunohistochemical analyses of ovotestis and bone marrow, blasts were positive for LCA, CD-13, CD-33 and CD 68. The cytogenetic analysis of the bone marrow shaved 46 XY karyotype. No response was achieved with combination chemotherapy and the patient died from progressive leukemia. Here we report a rare patient with myelodysplastic syndrome, EMD and hermaphroditism. To our knowledge this is the first case of MDS, EMD and hermaphroditism.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
4/10. Primary carcinoid tumor of the bilateral testis associated with carcinoid syndrome.Carcinoid tumors derived from neuroendocrine cells can release serotonin and other vasoactive substances into the systemic circulation, resulting in carcinoid syndrome. Testicular carcinoid, a rare disease accounting for less than 1% of all testicular neoplasms, rarely manifests symptoms of carcinoid syndrome. We describe a case of carcinoid syndrome arising from a primary testicular carcinoid tumor. A 21-year-old male patient presented with facial flushing and diarrhea for 5 years. He had an enlarged left testis and a 1-cm, ill-defined, hard, non-tender mass in his right testis. His 24 h urinary excretion of 5-hydroxyindoleacetic acid was elevated (16.1 mg/day). somatostatin receptor scintigraphy correlated with carcinoid tumor in both testes. Following bilateral orchiectomy, the patient's facial flushing and diarrhea disappeared.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
5/10. Metastatic spermatocytic seminoma--an extremely rare disease.Metastatic spermatocytic seminoma is an extremely rare disease with only one documented case in literature. We present another patient with metastatic disease confirmed by histological work-up after laparoscopic retroperitoneal lymph node dissection (L-RPLND).- - - - - - - - - - ranking = 5keywords = rare disease (Clic here for more details about this article) |
6/10. A case of Sweet's syndrome following septic pulmonary emboli after high-dose chemotherapy for advanced testicular cancer.A 33-year-old man with advanced testicular cancer underwent high-dose chemotherapy combined with peripheral blood stem cell transplantation. After administration of granulocyte colony-stimulating factor (G-CSF), multiple infiltrative erythema was identified on the face, thigh, and lower leg. A dermatologist diagnosed this as Sweet's syndrome caused by G-CSF; consequently G-CSF administration was stopped. When the skin lesions had improved, phlebitis was found at the injection site of the peripheral vein catheter. The patient then suffered from sudden left chest pain and dyspnea. Chest computed tomography showed the characteristic findings of septic pulmonary emboli (SPE). He was treated by the administration of vancomycin, fluconazole, and pazufloxacin mesilate. Although Sweet's syndrome and SPE are rare diseases, the presence of these diseases must be considered when performing chemotherapy for urological malignancy.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
7/10. Testicular metastasis from hepatocellular carcinoma.We document a case of testicular metastasis from hepatocellular carcinoma. The patient suffered from bilateral testicular painful swelling for 6 months. Scrotal ultrasonography showed bilateral testicular tumors and the whole abdominal computed tomography revealed a huge tumor in the left lobe of the liver. Bilateral orchiectomy and postoperative ultrasound-guided liver biopsy were done. Pathological examination revealed metastatic hepatocellular carcinoma. Hepatocellular carcinoma with testicular metastases is a very rare disease.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
8/10. Treatment of malignant leydig cell tumor.Malignant Leydig cell tumors (LCT) are rare. Only 32 cases of malignant LCT (as evidenced by metastatic spread) were reported. Generally metastatic spread occurs within 2 years of the primary LCT, and the patient dies within 2 years of the discovery of metastatic disease. The tumor is highly resistant to both radiation and chemotherapy. It also has a great propensity for recurring after surgical resection. A case is reported of a patient whose metastatic disease occurred 8 years after his primary LCT had been resected. He was treated with doxorubicin and mitotane without response. The clinical features of this case are highlighted, and a review of the literature describing treatment of this rare disease is presented.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
9/10.

10/10. Successful treatment of a bulky seminoma in an abdominal undescended testis: a case report.An undescended testis is a major risk factor for the development of testicular malignancy. Herein we report the case of a 40-year-old man with a bulky seminoma arising in an uncorrected abdominal undescended testis. The definitive diagnosis was established by results of sonoguided biopsy and tumor marker studies. The patient was successfully treated with initial cisplatin and etoposide combination chemotherapy followed by resection of the residual tumor. The optimal diagnosis and treatment of this rare disease is discussed.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
