1/121. Primary pure intratesticular fibrosarcoma.

    Testicular sarcoma appears to be a rare stromal tumor usually of indolent course with potential for distant metastases. A pure primary intratesticular fibrosarcoma in a 71-year-old male is presented. By the time the tumor became evident metastases had already occurred widely. The course was rapidly fatal. A review of the literature yielded only one case reported previously. The present case illustrates that pure fibrosarcoma occurs occasionally as a stromal tumor and may be associated with a dismal prognosis. The diagnosis of pure fibrosarcoma should be made only after extensive sampling of the testicular tumor to rule out an associated germ cell component. The differential diagnosis also includes the fibroma of gonadal stroma origin and the unclassified sex cord-stromal tumor with a predominance of spindle cells.

2/121. Cytogenetic and CGH studies of four neuroendocrine tumors and tumor-derived cell lines of a patient with multiple endocrine neoplasia type 1.

    A malignant insulinoma (LOHG-I), a carcinoid of the lung (LOHG-L), a parathyroid adenoma (LOHG-NSA), and a fibroma (LOHG-F) were obtained from a patient with multiple endocrine neoplasia type 1 (MEN1). Long-term cultures were established. Essential neurobiological properties of the cell lines were proven immunocytochemically and by electron microscopy. Molecular analysis of the germline dna showed a 4 bp deletion in exon 3 of the MEN1 gene. Cytogenetic and CGH analyses of the tumors/tumor cell lines revealed diploidy and balanced and unbalanced structural aberrations different for each tumor. chromosomes 6q21, 11q and 17q were most frequently involved in clonal structural aberrations.

3/121. Complete remission of pulmonary spindle cell carcinoma after treatment with oral germanium sesquioxide.

    Spindle cell carcinoma (SCC) is a rare form of lung cancer representing 0.2 to 0.3% of all primary pulmonary malignancies. Even with combined surgery, chemotherapy, and radiation therapy, these tumors are associated with a poor prognosis and only 10% of patients survive 2 years after diagnosis. We describe a patient with an unresectable SCC who, following no response to conventional treatment with combined modality therapy, chose to medicate herself with daily doses of germanium obtained in a health food store. She noted prompt symptomatic improvement and remains clinically and radiographically free of disease 42 months after starting her alternative therapy.

4/121. Bilateral recurrent pneumothorax complicating chemotherapy for pulmonary metastatic breast ductal carcinoma: report of a case.

    Secondary spontaneous pneumothorax (SSP) is a rare complication of chemotherapy for pulmonary metastases and to the best of our knowledge, only 28 cases have been described, most of which occurred in patients with osteosarcoma or germ cell tumors. We present herein the case of a 56-year-old woman in whom bilateral and recurrent SSP was caused by the rupture of pulmonary lacunae induced by chemotherapy, given for bilateral lung metastases secondary to breast carcinoma. Our experience of this case led us to conclude that: patients with pulmonary metastases may develop bilateral and/or recurrent pneumothoraces following chemotherapy; computed tomography scan is essential for defining the cause of SSP; and closed chest tube drainage remains the therapy of choice, while chemical pleurodesis may also be used to prevent recidivant SSP.

5/121. An intrapulmonary teratoma associated with bronchiectasia containing various kinds of primordium: a case report and review of the literature.

    An intrapulmonary teratoma (IPT), multiloculated and bronchiectatic, with two polyps inside a 23-year-old man is reported. The IPT, a very rare benign cystic lesion, was communicating with segmental bronchus and was removed by a segmental resection from the upper lobe of the left lung. The teratoma contained various kinds of primordial derivatives, such as mesoderm, ectoderm, and endoderm. Though 65 cases of IPT have been reported in the literature (1839-1996), in the present case there were over 15 germ derivatives, the largest number reported to date. The tumor contained thymic tissue, apart from mediastinum, which may be significant in relation to the pathogenesis of IPT. Clinical manifestations, age, and gender distributions and the kind of germ cell derivatives are discussed.

6/121. Hilar pulmonary granular cell tumor: a case report and review of the literature.

    We present a case of pulmonary granular cell tumor (GCT). A 35-year-old man underwent pulmonary resection for metastatic testicular mixed germ cell tumor when two interlobar lymph nodes were found to be enlarged and abnormal. Intraoperative frozen section examination showed their involvement by GCT. Histologic examination of the lobectomy specimen showed a benign, predominantly hilar GCT as well as metastatic germ cell tumor. This location, with no endobronchial component and with extension into regional hilar lymph nodes, is unusual. The differential diagnosis and the association with the metastatic testicular cancer are discussed and the literature on pulmonary GCT is reviewed.

7/121. Acute tumor lysis syndrome with choriocarcinoma.

    A 52-year-old man with retroperitoneal nodal, lung, and liver metastases from choriocarcinoma received chemotherapy with etoposide, cisplatin, and bleomycin. Within 48 hours of starting treatment, he had hypotension, hypoxemia, and anuria. Laboratory values showed hyperuricemia, hyperkalemia, hyperphosphatemia, hypocalcemia, and metabolic acidosis. He was placed on mechanical ventilation, and hemodialysis was instituted, with marked improvement in renal function. A second, shortened course of chemotherapy with carboplatin and etoposide was given 21 days later. However, on hospital day 48, the patient died of progressive pulmonary insufficiency and cardiac arrest. This represents the first reported case of acute tumor lysis syndrome after systemic chemotherapy for advanced nonseminomatous germ cell cancer.

8/121. Peritoneal carcinomatosis in germ-cell tumor: relations with retroperitoneal lymph node dissection.

    Peritoneal carcinomatosis from germ-cell tumor has rarely been described, and thus remains largely unknown. We report here five cases involving this entity. All five patients had embryonal carcinoma in their primary germ-cell tumor. Four of them had undergone retroperitoneal lymph node dissection (RPLND), and viable malignant cells were found. RPLND was performed for relapses (n = 3) and as primary therapy for stage II disease (n = 1). The peritoneum was the only site of relapse in three patients, and was associated with pleural effusion in one. The time to relapse after RPLND ranged from 6 to 14 months. One patient sustained injury to lymph nodes during RPLND, and another patient had a peritoneal xanthelasma. The only three patients already described in the literature underwent RPLND or surgical biopsy. All these observations suggest a striking relation between RPLND and occurrence of subsequent peritoneal carcinomatosis.

9/121. Recurrent arterial embolization from a metastatic germ cell tumor invading the left atrium.

    Arterial embolization of a malignant tumor is extremely rare. We report an unusual case of a young adult man who presented with acute lower limb ischemia and a mass in the right lung and left atrium. These clinical manifestations were the result of metastases and embolization from a germ cell tumor and were the first indication of malignancy in this patient. The importance of appropriate investigations in the subsequent treatment is stressed.

10/121. Intrapulmonary teratoma associated with thymic tissue.

    A case of benign, cystic intrapulmonary teratoma occurring in the right lobe of a 22-year old female is described with grossly and microscopically findings. The connection between the tumor and the segmental bronchus, together with the absence of germ cell neoplasms in other locations, clearly established the true intrapulmonary nature of the lesion. The unusual finding of thymic tissue within the wall supports the possible origin from the third pharyngeal pouch.
