During the 7-year period between June 1985 and May 1992, 34 patients with pineal lesions underwent 66 stereotactic procedures (37 biopsies, 19 third ventriculostomies, 6 cyst aspirations, 3 instillations of 32P into cysts, and 1 insertion of an Ommaya reservoir into a cyst) at the Mayo Clinic. Nine patients subsequently also underwent 10 open resections of lesions of the pineal region. In the 34 study patients, the pathologic entities were 9 gliomas (5 astrocytomas, 2 ependymomas, and 2 oligodendrogliomas), 9 germ cell tumors (7 germinomas, 1 entodermal sinus tumor, and 1 malignant teratoma), 8 pineal parenchymal tumors (3 pinealomas, 3 pinealoblastomas, 1 mixed pinealoma-pinealoblastoma, and 1 intermediate differentiation pineal tumor), 4 other malignant tumors (2 undifferentiated carcinomas, 1 malignant melanoma, and 1 non-Hodgkin's lymphoma), 2 meningiomas, and 2 nonneoplastic lesions (1 glial cyst and 1 inflammatory lesion). No mortality or permanent morbidity was associated with the 66 stereotactic procedures; 2 patients had temporary complications--1 neurologic (transient diplopia) and 1 nonneurologic (pulmonary embolism). Diagnostic tissue was obtained in 33 of the 34 patients. An algorithm for the diagnosis and management of patients with lesions of the pineal region is presented. We conclude that stereotactic biopsy of pineal lesions can be performed safely, has a high diagnostic yield, and facilitates rational planning of treatment.

A 57-year-old female patient with known cardiac disease developed a 4 to 6 week history of diarrhea, followed by onset of orthopnea and subsequent right-sided cardiac failure. On hospital admission she was found to have pure tricuspid regurgitation, without evidence of cardiac ischemia, pulmonary embolism, bacterial endocarditis or pericardial disease. A 24-hour urine collection for 5-HIAA was elevated, and a subsequent octreotide scan documented abnormal uptake in the pelvic cul-de-sac. Bilateral ovarian masses were found at laparotomy, which on pathological examination were found to be a benign left ovarian cystic teratoma, and a right carcinoid tumor of the ovary. This patient presented with systemic complaints of diarrhea, and orthopnea and right sided heart failure that on evaluation were ultimately found to be due to a unilateral primary carcinoid tumor of the ovary, which accounts for less than 0.1% of all ovarian carcinomas, and only 5% of all carcinoids. Treatment of this malignant carcinoid syndrome presentation consisted of debulking of the tumor and continuation of her diuretics and digoxin. Diarrhea and orthopnea ceased within 2 weeks after her oophorectomy. On evaluation 6 weeks and 6 months postoperatively, her cardiac function was stable, though unchanged. 5-HIAA levels were within normal limits, demonstrating the curative function of surgery in patients with unilateral ovarian carcinoid without evidence of metastases, as well as preserved cardiac function in otherwise stable patients.

We report a unique case of metastatic malignant teratoma from an undescended testis which presented with acute pulmonary embolism. After chemotherapy, the undescended right testicle was resected along with a cord of non- obstructing inferior venal caval tumour which extended into the right atrium with tumour floating free within the atrium at the end of the cord of tumour. The presentation, diagnosis and treatment of testicular tumours is described and the literature pertaining to testicular tumours in military personnel reviewed.

Laparoscopic surgery is usually considered to be less invasive when compared to traditional laparotomy, and is regarded as a relatively low-risk procedure for postoperative complications because of the reduced surgical stress and earlier mobilization. However, we describe a 47-year-old woman who presented with acute respiratory distress, drowsy consciousness, and circulatory collapse shortly after gynecologic laparoscopic ovariectomy for removing an ovarian teratoma at a local hospital. After resuscitation, the patient was transferred to our emergency department. Immediate bedside electrocardiographic and echocardiographic examination results led to acute pulmonary embolism being quickly diagnosed. The patient received subsequent intensive care with smooth course. Although pulmonary embolism is rare after laparoscopic surgery, early detection and quick treatment are important in the management of this life-threatening complication and offer good prognosis. The risk of pulmonary embolism after gynecologic laparoscopic surgery remains unclear. Therefore, the decision to provide prophylaxis is up to the individual physician, and should take into consideration the patient's individual risk factors and comorbidities.

A 24-year-old man was referred to our hospital with a painless mass on the left side of his neck. Ultrasonography detected right testicular tumor and computerized tomography scanning revealed a left supraclavicular lymph node mass and bulky retroperitoneal lymph node mass. He initially underwent right high orchiectomy, combination chemotherapy and retroperitoneal lymph node dissection for advanced testicular non-seminomatous germ cell tumor. Six years later, late relapse was detected in the lung. After complete remission of the lung metastasis with chemotherapy, the serum alpha-fetoprotein began to increase because of superior vena caval thrombus extending into the right atrium. Emergency surgical excision was performed successfully using extracorporeal circulation to prevent pulmonary embolism and the resected specimen pathologically revealed adenocarcinoma interpreted as teratoma malignant transformation. Adjuvant chemotherapy consisting of paclitaxel, ifosfamide and nedaplatin were administered for subsequent slight elevation of serum F-human chorionic gonadotropin beta, resulting in successful normalization again. Later, he suddenly died of cerebral infarction without any evidence of recurrence 138 months after his initial presentation. We report herein an extremely uncommon case of advanced testicular germ cell tumor with development of superior vena caval thrombus extending into the right atrium.

Intracardiac metastases of germ cell testicular tumors are not commonly seen in clinical practice. The clinical presentation of right-sided heart metastases ranges widely. Depending upon its size and intracardiac location, it could be highly symptomatic, leading to a congestive heart failure, pulmonary embolism, and death, or completely asymptomatic. Improved imaging techniques and treatment strategies demonstrate that right-sided heart metastasis should be considered a potentially dangerous but treatable disease. Presented is the case of a 24-year-old man with a testicular nonseminomatous germ cell tumor, which after metastasizing in the right atrium differentiated into a teratoma and resulted in an inflow obstruction of the right ventricle.

Conservative surgery with adjuvant chemotherapy has made the preservation of fertility even in patient with advanced disease. The increase in cure rate has shifted to research for the long term menstrual reproductive and gynecologic outcome in these patients. The current study is retrospective for 25 cases of ovarian malignant germ cell tumor from January 2006 to January 2011, at El Hussian and Sayed Galal University Hospitals. The uterus and contralateral ovary were retained to preserve ovarian function with or without chemotherapy, followed up for two years. The mean age of most patients ranged from 15-28 years (average 21.5 years). According to International Federation of Gynecology and Obstetrics, the histological subtypes were ten dysgerminoma (40%). Five immature teratoma (20%), three endodermal sinus tumor (12%), four mixed germ cell tumor (16%) three embryonic cell tumours (12%). Stage I: tumors 15 cases (60%), Stage II: tumors one case (4%), Stage III tumors 6 cases (24%), Stage IV tumors 3 cases (12%). Adjuvant chemotherapy was administered to 15 cases 60% and followed up for two years. There were two recurrences, one died at 7th day postoperative of massive pulmonary embolism with past history of D.V.T, five healthy live births in the chemotherapy group without birth defects, and one infertility case 4%.
