1/18. Prenatal sonographic features of embryonal rhabdomyosarcoma.

    We describe a case of fetal rhabdomyosarcoma detected during the third trimester of pregnancy by prenatal sonography. At 33 weeks' gestation, sonography performed because of suspected polyhydramnios showed a solid mass of 120 x 54 mm arising from the anterior wall of the fetal thoracic cage. Another mass within the left maxillary area which originated from the left orbital floor was also detected. In the abdomen, there were multiple round masses in and around the liver. As the previous scan at 28 weeks had appeared normal, the multiple masses which became visible and enlarged rapidly in different locations led us to believe that there was fetal cancer. The most likely diagnosis was rhabdomyosarcoma (which was later confirmed), because it is the most prevalent soft-tissue tumor in children and may develop within or outside muscle anywhere in the body and at any age. Two other reported cases which were detected by prenatal ultrasound examination are also discussed.

2/18. rhabdomyosarcoma in a child with massive pleural effusion: cytological diagnosis from pleural fluid.

    We report on a case of embryonal rhabdomyosarcoma in an 11-yr-old boy investigated for mild chest pain after trauma. Chest radiography showed a massive right pleural effusion. Cytological analysis of the pleural fluid demonstrated the presence of malignant small undifferentiated cells. The rhabdomyoblastic nature of the cells was confirmed by positive immunostains of HHf35 actin, desmin, and skeletal muscle myosin; histological examination of a core biopsy confirmed the diagnosis of rhabdomyosarcoma. Computed tomography and gallium scan revealed the presence of an extensive anterior and lower chest wall mass involving the mediastinum, as well as retroperitoneal lymphadenopathy. Massive pleural effusion is a frequent presentation in malignant disease, but is rare in rhabdomyosarcoma. The immunochemical stain studies performed on cytological smears in this case proved to be very useful for making the definitive and accurate diagnosis. Diagn. Cytopathol. 1999;21:125-128.

3/18. Integrated diagnostic imaging of primary thoracic rhabdomyosarcoma.

    We report a rare case of primary thoracic rhabdomyosarcoma in a girl who was referred with acute chest pain, hacking cough, and wheezing. A chest X-ray revealed a complete opacity of the right hemithorax. Ultrasound revealed a right-sided pleural effusion and a solid mass above the liver dome, suggesting a neoplastic disease, which quickly led to further specific examination. Use of CT and MRI together with bone scintigraphy completed the investigation. The biopsy specimen showed a pattern of alveolar rhabdomyosarcoma. This case was reported to emphasize the role of US in the evaluation of a child with hemithorax opacity.

4/18. Primary chest Hodgkin's disease diagnosed by pleural biopsy: case report.

    Hodgkin's disease involving the lung and pleura is rare. A case of a 40-year-old woman with one year history of pain in the left arms spreading into chest is presented. Computed tomography showed a mass of 5 x 7 cm in the left hemithorax mediastinum and pleura, pleural effusion and mediastinal lymphadenopathy. Diagnostic methods including percutaneous needle aspiration biopsy of pleura, brochoscopic biopsies, bronchoalveolar lavage, cytological examination of the pleural fluid did not disclose any pathological diagnosis. Lastly, we performed pleural biopsy by video-assisted thoracoscopic surgery and we showed that the lesion was HD of nodular sclerosing type.

5/18. Orthotopic heart transplantation in a child with severe heart failure and chylous ascites.

    We report a case of a heart transplantation in a 12-year-old girl 9 years after extensive lung resection and adjuvant chemo- and radiotherapy for intra-thoracic embryonic rhabdomyosarcoma. She had restrictive cardiomyopathy with severe heart failure and chylous ascites. She was treated successfully with orthotopic heart transplantation and her symptoms of chylous ascites subsided gradually after transplantation. Her abdominal girth decreased from 79 cm before the transplant to 53 cm 9 months after the transplant.

6/18. A case of small round cell tumor of the thoracopulmonary region with myogenic and neurogenic elements.

    We here report a unique case of a young boy with an intrathoracic tumor which consisted of neurogenic and myogenic elements. The initial pathological diagnosis was alveolar rhabdomyosarcoma. The tumor tissue from surgical resection was composed of three parts, each showing a different histological appearance, i.e. a monotonous small cell area, an alveolar area, and an area consisting of pleomorphic rhabdomyoblasts. The small round cells in the monotonous area were immunoreactive with the antibodies for Leu7, neuron-specific enolase (NSE), neurofilament proteins (NFP), and beta 2 microglobulin, but not with the antibody for desmin. These cells also had dense core granules. The tumor cells in the alveolar area were immunoreactive with the antibodies for Leu7 and desmin, but not with the antibody for NFP. Pleomorphic rhabdomyoblasts were immunoreactive with the antibody for desmin, but not with the antibodies for Leu7 and NFP. These findings imply that this tumor consisted of neurogenic and myogenic elements and is considered to be a special type of rhabdomyosarcoma.

7/18. Unclassified rhabdomyosarcoma in a patient with anti-Hu syndrome.

    Anti-Hu syndrome is a paraneoplastic neurological syndrome, most frequently associated with small cell carcinoma of the lung. Subacute sensory neuronopathy is thought to be the most frequent presentation of the anti-Hu syndrome, but it seems that sensory-motor neuropathy is the most common form in the anti-Hu neuropathy. Neurological symptoms often appear before the associated cancer has been identified. Sometimes the tumor is discovered months or even a few years after the appearance of the neurological syndrome. FDG-PET scan seems a better method for finding the tumor in patients with paraneoplastic neurological syndrome and anti-Hu antibodies who had negative test results after an initial workup using radiological methods. In this case report we present a patient with the anti-Hu syndrome associated with an unclassified rhabdomyosarcoma with epitheloid cellular morphology and neuroendocrine differentiation.

8/18. A disseminated alveolar rhabdomyosarcoma in a 9-year-old boy disclosed by chromosomal translocation (2;13) (q35;q14)

    A 9-year-old boy presented with a small subcutaneous tumor of the trunk and diffuse bone marrow involvement. The first histological diagnosis given was undifferentiated malignancy possibly of neural crest origin and chemotherapy was started immediately using vincristine, cyclophosphamide, cisplatin, and teniposide (OPEC). Complete response was achieved after four courses of chemotherapy. Histological slides were then reviewed and the final diagnosis of alveolar rhabdomyosarcoma (RMS) was retained. Moreover, chromosome analysis of malignant cells in the bone marrow revealed a translocation involving chromosomes 2 and 13:t(2;13) (q35;q14). This specific karyotype finding has been recently reported in a few cases and could be specific for alveolar RMS. The patient had a relapse 7 months after diagnosis and died 4 months later.

9/18. Unusual leukemic presentation of rhabdomyosarcoma: report of two cases with immunological, ultrastructural and cytogenetical studies.

    BACKGROUND: bone marrow infiltration occurs rarely at presentation of rhabdomyosarcoma (RMS) or other childhood solid tumors. This possibility leads to misdiagnosis of leukemia and incorrect therapies might be administered. methods: We report two patients presenting with diffuse bone marrows involvement by neoplastic cells. Initial studies were not consistent with a diagnosis of leukemia and the cases were further studied extensively by indirect immunofluorescence, immunocytochemistry, electron microscopy and cytogenetics. RESULTS: In both cases blast cells were large, poorly differentiated, with immunological reactivity to the anti-desmin antibody. Ultrastructural findings of muscular features and chromosomal translocation t(2;13) (q37;q14) further confirmed the diagnosis of rhabdomyosarcoma of the alveolar subtype. This was then confirmed histologically in one patient. CONCLUSION: This study stresses the utility of analyzing cases of morphologically undifferentiated marrow blast cells by various techniques, as well as investigating for different types of both hematological and solid neoplasms.

10/18. Sarcoma following irradiation for breast cancer. Report of three unusual cases including one malignant mesenchymoma of bone.

    Three cases of sarcoma developing after irradiation for breast cancer are reported. A malignant mesenchymoma in the sternum--a combination of osteogenic sarcoma and rhabdomyosarcoma--is the first documented case of its kind occurring after radiation therapy. Of the other two tumors one was an extraskeletal osteogenic sarcoma in the soft tissues of the thoracic wall and one a rhabdomyosarcoma in the axilla.
