1/1569. Spontaneous partial expectoration of an endobronchial carcinoid.

    Typical pulmonary carcinoid tumors often present as proximal endobronchial masses discovered during the evaluation of cough and/or hemoptysis. We present a case of a carcinoid tumor that presented with spontaneous partial expectoration. A review of the literature revealed 16 cases of expectoration of fragments from various primary and metastatic tumors. Our case appears to be the first report of the expectoration of a carcinoid tumor. ( info)

2/1569. Coronary spasm and cardiac arrest from carcinoid crisis during laser bronchoscopy.

    Bronchoscopic manipulation of an endobronchial carcinoid can precipitate a carcinoid crisis. Coronary artery spasm is an uncommon manifestation of carcinoid crisis, and has never been reported as a complication of flexible bronchoscopy. We report a case of a 10-year-old girl who developed coronary artery spasm and cardiac arrest during neodymiumyttrium aluminum garnet (Nd-YAG) laser photoresection of an endobronchial carcinoid. Recognition of this unusual presentation of a carcinoid crisis is important as the treatment approach differs from standard resuscitation protocols. ( info)

3/1569. Ovarian strumal carcinoid with severe constipation: immunohistochemical and mRNA analyses of peptide yy.

    Functioning ovarian carcinoid tumors are well known to cause carcinoid syndrome. Recently, strumal and trabecular ovarian carcinoid tumors are reported to cause severe constipation possibly because of tumor-producing peptide yy (PYY). We studied a case of primary ovarian strumal carcinoid who had had severe constipation until the tumor was removed by surgical operation. Immunohistochemically, many tumor cells were strongly positive for PYY. By Northern blot and reverse transcription polymerase chain reaction analyses, PYY mRNA was expressed in a complete form as detected in normal human colon mucosa. From these findings, an ovarian strumal carcinoid is strongly suggested to express complete PYY mRNA and therefore complete PYY protein that results in severe constipation. ( info)

4/1569. 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.

5/1569. Bone metastases from bronchial carcinoid tumors. Two case-reports.

    Two case-reports of metastatic bone disease in patients with bronchial carcinoid tumors illustrate the diagnostic challenges raised by these slowly-growing malignancies of which the primary frequently escapes early identification. The first patient had the typical picture of a primary with a single bone metastasis. Unusual features in the second patient were the large number of bone metastases, involvement of distal skeletal sites, and elevation of serotonin and 5-hydroxyindoleacetic acid levels. ( info)

6/1569. Carcinoids of the common bile duct: a case report and literature review.

    Carcinoids of the extrahepatic bile ducts and particularly the common bile duct are extremely rare. A 65-year-old woman presented with obstructive jaundice. Laboratory and imaging studies gave results that were consistent with an obstructing lesion in the common bile duct. In this case, a stent was inserted initially to decompress the bile ducts. Subsequently a laparotomy and pancreaticoduodenectomy were performed and a tissue diagnosis of carcinoid of the common bile duct was made. The patient was well with no evidence of recurrence 17 months postoperatively. The authors believe this is the 19th reported case of an extrahepatic bile duct carcinoid. ( info)

7/1569. Primary hepatic carcinoid in a renal transplant patient.

    There seems to be a world-wide increase in the incidence of tumors among immunosuppressed patients. Of 1350 renal allografts transplanted in the past 23 years at the Department of transplantation and Surgery, 56 cases were malignant tumors. The case of a 58-year-old female patient is reported, with disseminated primary carcinoid in the liver detected 86 days after renal transplantation. According to the literature only 39 patients with primary liver carcinoids have been reported until 1997, but this is the first where the carcinoid developed in an immunosuppressed patient. The rapid progression of the carcinoid could be associated with the immunosuppression. ( info)

8/1569. Multiple endocrine neoplastic-associated thymic carcinoid tumour in close relatives: octreotide scan as a new diagnostic and follow-up modality. Two case reports.

    Thymic carcinoid tumours constitute less than 1% of all carcinoids, and differ markedly from true thymomas in natural history, morphology, prognosis and therapeutic options. New clinical and diagnostic modalities are described in two brothers with thymic carcinoid associated with multiple endocrine neoplasia syndrome. octreotide scintigraphy proved useful for diagnosis and follow-up, and somatostatin receptor positivity may provide new prospects for treatment of non-resectable or recurrent tumour.

9/1569. 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. ( info)

10/1569. pyoderma gangrenosum with carcinoid tumor.

    A patient with the classic lesions of pyoderma gangrenosum was found on autopsy to have a carcinoid tumor of the ileum. The simultaneous occurrence of a carcinoid tumor with pyoderma gangrenosum is interesting because both conditions are associated with immunologic defects. ( info)
