Respiratory muscle function was assessed in six patients with the Lambert-Eaton myasthenic syndrome. Five had histologically proved small cell carcinoma of the lung; the sixth later developed metastases from an unknown primary site. Two patients had ventilatory failure, one without respiratory symptoms; another, who had emphysema, had dyspnoea and orthopnoea. The remaining three patients had no respiratory symptoms. Four patients had limb muscle weakness as judged by the maximal voluntary contraction of the quadriceps muscle (range for all subjects 32-100% predicted). Transdiaphragmatic pressure (Pdi) was measured during a maximal unoccluded sniff (Pdi: sniff), a maximal sustained inspiratory effort against a closed airway (Pdi: Pimax), and phrenic nerve stimulation (Pdi: twitch). Mild to moderate diaphragmatic weakness was present in all six patients in proportion to the degree of leg weakness (Pdi: sniff 30-64% predicted; r = 0.6; Pdi:Pimax 6-69% predicted, r = 0.8); this was associated with very low or absent Pdi:twitch during phrenic nerve stimulation. Four patients had weakness of the expiratory muscles. Improvement in muscle strength was documented in two patients after tumour chemotherapy and specific treatment with 3,4-diaminopyridine and prednisolone; one patient was still alive five years from first diagnosis. It is concluded that the respiratory muscles may be implicated in this condition more often than has previously been recognised. As the lack of mobility may cause respiratory symptoms to be minimised, the presence of respiratory muscle weakness may remain undiagnosed unless formal measurement of respiratory muscle function is made.

A 68-year-old woman, known to have a secundum atrial septal defect which had been asymptomatic, reported dyspnea and occasional chest pain for two years. Admission examination revealed orthopnea, cyanosis, polycythemia and inflow congestion of the upper part of the body. After some blood-letting, nifedipine and nitrates brought immediate relief of symptoms. Physical examination, chest x-ray and ECG were not different from previously known findings. All laboratory tests were normal. The findings on cross-sectional echocardiography raised the suspicion of a right ventricular tumor, which was then demonstrated by computed tomography. There were no metastases. Under extracorporeal circulation a right-ventricular benign myxoma, attached to the apical septum and the size of a tennis-ball, was removed. The postoperative course was without complications and the patient was discharged symptom-free.

Two case reports of primary cardiac sarcoma, which is uncommon, are presented. The first case, a 38-year-old male, complained of chest tightness. Chest roentgenograms showed enlargement of the cardiac shadow and left pleural effusion. Transthoracic echocardiography and chest magnetic resonance imaging showed a tumor in the right atrium, and pericardial effusion. The tumor involved the right atrial wall and interatrial septum, and was partially resected. Pathohistological examination revealed angiosarcoma. He died 1 month later. The second case, a 19-year-old male complained of dyspnea and orthopnea. Chest roentgenograms showed pulmonary congestion. Transthoracic echocardiography showed a large mobile mass in the left atrium. An emergency operation was performed and the tumor was totally resected. Pathohistological examination demonstrated leiomyosarcoma. The postoperative course was uneventful, but the tumor rapidly recurred. Second and third operations were performed at intervals of 2 months. After the third operation, he was treated with radiotherapy. Local recurrence was not found but multiple distant metastases were found 2 months after completion of radiation therapy.

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.

The term myxosarcoma is currently not used in standard classification for soft tissue tumors, but restricted to cardiac tumors. Primary cardiac myxosarcoma is a very rare disease and is difficult to differentiate from myxoma clinically and pathologically. We report a case of left atrial myxosarcoma with widespread systemic metastasis in a 21-yr-old male. The patient presented with sudden onset of intermittent dyspnea and orthopnea. Echocardiography showed a mobile, pedunculated tumor, 7.5x5x2 cm in size, at left atrium. Histologically, the excised tumor showed an amorphous finely fibrillar and mucinous stroma, in which irregular cords and clusters of lepidic cells and large stellate cells with plump vesicular nuclei resembled the usual type of cardiac myxoma were noted. And it showed focally cellular area with great nuclear pleomorphism and frequent mitoses. The patient received combination chemotherapy, peripheral blood stem cell collection transplantation and operations for systemic metastases in the brain, skeletal muscle and lung. He is alive at present 37 months after initial diagnosis and has no more new metastatic lesion.

A 32-year-old man presented with cough, dyspnea and orthopnea ten years after amputation of the right humerus because of osteosarcoma. Chest radiographs and chest computed tomographs showed left pleural effusion, pericardial effusion and a giant intrathoracic mass, which was histologically diagnosed as a recurrence of the osteosarcoma. After 4 courses of chemotherapy combined with CDDP, the mass in the left upper lobe of the lung decreased in size, and it was then resected. Three months later, new metastatic lesions were detected in the thoracic area. Therefore, 29 additional courses of chemotherapy were administered (36 courses in total over 4 years; including regimens combined with CDDP, carboplatin, high-dose methotrexate, ifosfamide, dacarbazine, vindesine, etoposide, vincristine, taxotere and gemcitabine). In spite of the several courses of chemotherapy, brain and spinal cord metastases appeared, and the patient eventually died of cerebral hemorrhage. During the four years after the first recurrence he had good quality of life as a result of the chemotherapy.

A case of gestational trophoblastic tumor (GTT) concurrent with an intrauterine pregnancy is reported in a 21-year-old gravida 2 para 0 (0010) who presented with dyspnea, orthopnea, headache, and blurring of vision at 33 weeks age of gestation. She had a history of hydatidiform mole for which curettage was done. Chest radiograph showed pulmonary metastases, with pleural effusion on both lungs. Serum beta subunit of human chorionic gonadotropin was abnormally elevated for age of gestation. Due to worsening maternal pulmonary condition, the patient underwent primary, low segment cesarean section and was subsequently started on multidrug chemotherapy. This is the first reported case of GTT in pregnancy in the Philippines in which both the mother and the infant survived. Several hypotheses regarding its origin, its diagnosis, and its management and prognosis are presented. This case report emphasizes the importance of early diagnosis and treatment to improve the prognosis of both the mother and the infant.

A 69-year-old female with a previous hemisternectomy for recurrent phyllodes tumour was referred for echocardiography because of progressive dyspnoea, orthopnea, and a diastolic mitral rumble on auscultation. Transthoracic echocardiography revealed a large left atrial mass. Although a diagnosis of myxoma was likely, there was concern that this was a cardiac metastasis. A tissue diagnosis was mandatory before further thoracic surgery could be considered. This was obtained via a trans-septal puncture using transoesophageal echocardiographic guidance. Histology confirmed a diagnosis of myxoma, and our patient underwent successful surgery. This case highlights the importance of obtaining accurate tissue diagnosis and of excluding metastatic disease in patients with a cardiac mass and a history of tumour, prior to deciding whether surgical excision is warranted.

We describe a man who was diagnosed with non-small cell lung cancer following previous treatment for small cell lung cancer. He developed dyspnoea, paroxysmal nocturnal dyspnoea and orthopnoea. Trans-thoracic echocardiogram revealed a large mass within the right atrium. The patient proceeded to thoracotomy at which time unresectable metastatic tumour was found in the right atrium infiltrating into the pericardium. Metastatic involvement of the heart by tumour is rare and is found at autopsy in 1-3% of unselected cases in various series. This translates into a finding of cardiac metastases in approximately 10% of autopsies where malignancy is diagnosed. Most cases are clinically silent and are undiagnosed in vivo. Echocardiography, CT and MRI are complementary investigations, and are all used in the evaluation of cardiac lesions. When metastatic disease is in question, MR and CT imaging offer advantages over echocardiography, chiefly a wider imaging field which allows evaluation of distant disease.

Nasopharyngeal carcinoma (NPC) is prevalent in Taiwan and is characterized by a high frequency of nodal metastasis. The most common organs with distal metastases are the bones, lungs, and liver, with extremely rare cases to the pericardium. Herein, we report a rare case with NPC who presented with dyspnea and orthopnea. Serial studies, including pericardial biopsy, revealed NPC with pericardial metastasis and pericardial effusion. The tumor cells of both the original and metastatic tumors were positive for Epstein-Barr virus by in situ hybridization. This is the first histologically confirmed case of NPC with pericardial metastasis.
