We describe the case of a 28 years old caucasian woman with tuberous sclerosis diagnosed at 23 when she underwent nephrectomy for a left renal angiomyolipoma with massive hematuria. She had adenoma but she presented on mental deficit and there was no record of seizures. Familiar history was negative except for the presence of adenoma sebaceum in her father, aged 63, and in her only daughter, aged 10. Five years after nephrectomy she was admitted to our hospital because of exertional dyspnoea and haemoptysis. Pulmonary involvement was confirmed by chest X-rays and CT scans.

A 63-year-old male complained of palpitation and dyspnea. ECG showed paroxysmal supraventricular tachycardia. Echocardiogram revealed asymmetrical thickening of the cardiac septum, and by other clinico-pathological observations, nephrotic syndrome and colon adenoma were detected. For these diseases, steroid therapy and operation were performed, respectively. Ten months later, chest X-ray revealed diffuse abnormal shadow in the bilateral lung fields, and the patient expired due to respiratory distress syndrome. The patient's heart weighted 300g and showed extensive myofibril disarray in bilateral ventricles involving the septal region of the heart. Degeneration and atrophy of the atrioventricular node was seen. In the lungs, organizing pneumonia, old pleuritis, diffuse septal fibrosis and cytomegalovirus infection were demonstrated in the alveolar walls. Kidneys showed slightly sclelotic changes in glomeruli and edema-fibrosis in the interstitium. In this rare case, hypertrophic cardiomyopathy was combined with nephrotic syndrome due to glomerular change, and colon adenoma. The patient died of cytomegalovirus infection in the lungs. The histogenesis of myofibril disarray was discussed in these diseases.

A 44-year-old male was admitted because of dyspnea. Bronchoscopy revealed a tumor obstructing 85% of the tracheal lumen, at the site of the membranous portion, 3 cm below the vocal cords. The tumor was removed by sleeve tracheal resection with end to end anastomosis. Histological findings showed benign mixed tumor (pleomorphic adenoma) arising from the tracheal wall. Postoperative course was uneventful. Only 5 tracheal mixed tumors have been found in the Japanese literatures. Therapeutic approach to this tracheal tumor is discussed in this paper.

Two unusual cases of pleomorphic adenoma (benign mixed tumor) of the trachea were found in a 56-year-old woman and a 20-year-old man. Both patients had been initially treated for presumed bronchial asthma for 5 years and 4 years, respectively. Pulmonary function tests in each showed typical extrathoracic obstruction. The diagnosis of tracheal lesions in both cases was based principally on the following: 1) dyspnea without complete remission over an extended period of time following initial examination; 2) marked retraction of the supraclavicular and suprasternal notches during inspiration with stridor on physical examination; and 3) a high degree of suspicion. Large tumors were found within the air column of the trachea by soft tissue density X-ray films and electroradiographs of the neck, CT scans of the neck and mediastinum in each patient revealed that the tumor originated from the membranous layers of the trachea in the woman and the posterolateral wall of the trachea in the man. Fiberoptic bronchoscopy confirmed the clinical diagnosis. Both cases were successfully treated by segmental resection of the trachea with end-to-end anastomosis.

Severe cardiac arrhythmias (Lown class IVa), rapid loss of physical capacity and dyspnoea on the slightest exertion occurred in a 55-year-old man with idiopathic dilated cardiomyopathy. In the preceding year he had recurrent diarrhoea and lost 23 kg in weight. He was found to have hypercalcaemia (3-3.2 mmol/l). The heart failure significantly improved under treatment with twice daily 12.5 mg captopril, 100 mg spironolactone daily, furosemide 40 mg twice daily, and digitoxin 0.07 mg daily. The arrhythmia responded to verapamil 80 mg and quinidine 160 mg, both drugs three times daily. Primary hyperparathyroidism was found to be the cause of the hypercalcaemia (parathormone 84 pmol/l). After the parathyroid adenoma had been removed the patient's condition again improved markedly. There were only rare monotopic extrasystoles, cardiac size regressed, and diuretics were no longer necessary. His medication at present is verapamil (80 mg three times daily), captopril (12.5 mg three times daily) and digitoxin (0.07 mg daily). It is concluded that the hypercalcaemia influenced the severity of the cardiomyopathy. It would seem that both intra- and extracellular calcium homoeostasis is of great importance in dilated cardiomyopathy.

Twenty-two patients (17%) with thyroid cancer evidenced by major clinical features of hyperthyroidism were encountered out of 129 patients with thyroid cancer operated on. Clinical complains consisted of palpitation, dyspnea, nervousness, increased appetite, and weight loss. Preoperative BMR of 12 patients ranged from +17% to +41%, averaging +31.4%. Definite diagnosis was made by preoperative biopsy in two patients, the remainder was misdiagnosed as having primary hyperthyroidism (12), nodular goiter (6), and adenoma (2). The causes of misdiagnosis, coexistence of thyroid cancer and hyperthyroidism, and prognosis were discussed. we conclude that fine needle biopsy is the most effective way to establish correct preoperative diagnosis.

Thirty-eight cases of bronchial adenoma seen at Taipei VGH during 1976-88 were reviewed. Nine were carcinoid tumors, 14 were mucoepidermoid carcinomas and 15 were cylindromas. There were 21 men and 17 women. Ages ranged from 6 to 81 years with a mean of 43. Twenty-five were primary tumors of lung and 13 were metastasized from distant sites. The commonest presenting symptoms were hemoptysis, persistent cough, dyspnea and chest pain. In primary bronchial adenomas, the mean duration of symptoms was similar for carcinoids and cylindromas, around 16 months, and shortest for mucoepidermoid carcinomas (2.9 months). Single mass lesion was the most common chest X-ray finding of primary adenomas, while multiple nodules were the commonest for metastatic adenomas. Most of the primary tumors (80%) were visible by bronchoscopy, which showed predilection of trachea for cylindromas, left-sided for mucoepidermoid carcinomas and right-sided for carcinoids. The mean age at presentation was similar for all types of primary adenoma, around 44.5 years, while more younger in patients with metastatic cylindroma than mucoepidermoid carcinoma. Most of the primary adenoma were resectable, however, post-operative chemotherapy or radiotherapy was required in 4 mucoepidermoid carcinomas and 2 cylindromas. All types of bronchial adenomas showed malignant potential, mean duration before metastasis was about 2 years (3 months to 4 years), most of them were mucoepidermoid carcinomas (60%). The 5-year survival rate was 11.1% for mucoepidermoid carcinomas, 55.6% for carcinoids and 83.3% for cylindromas. We conclude that the term bronchial adenoma represents a heterogenous group of tumors with considerable malignant potential and should not be ignored by its term of benignity.

A survey is given of upper respiratory tract tumors in Cpb:WU (Wistar random) rats. Data were collected from ten 24- to 30-month toxicity/carcinogenicity studies and from one 12-month study. Nasal tumors may lead to dyspnea, mouth breathing, and nasal discharge. These clinical signs mainly occurred in rats bearing squamous cell carcinomas. The large nasal tumors were often osteolytic, they invaded the subcutis over the premaxilla, resulting in swellings on the back of the nose, and extended into the brain. The incidence of nasal tumors in untreated male controls was 1.1% (7/661), the tumors invariably being squamous cell carcinomas. There were no nasal tumors found in untreated female controls. The type of compound-induced nasal tumor most frequently observed was adenocarcinoma (of the olfactory epithelium) followed, in order of decreasing incidence, by squamous cell carcinoma, carcinoma in situ, polypoid adenoma, Schwannoma, and carcinosarcoma. It was proposed that adenocarcinomas of the olfactory epithelium should be classified as neuroepitheliomas. It was also suggested that squamous cell carcinomas, seen in association with necrotizing inflammation of an incisor tooth, should be considered as part of the malocclusion syndrome. No spontaneous tracheal tumors were observed, and only one out of 422 untreated female controls (0.2%) was seen to have a laryngeal tumor, an adenoma. Induced laryngeal tumors included carcinoma in situ, squamous cell carcinoma, and adenocarcinoma. Squamous cell carcinoma was the only type of treatment-related tracheal tumor found. The incidences of induced laryngeal and tracheal tumors were very low, and in no case were these tumors statistically significantly different from the respective incidences in controls.

Six patients with parapharyngeal space tumors presenting intraorally over the past 16 years were managed by transoral excision. All had benign tumors of salivary gland origin (1 monomorphic and 5 pleomorphic adenomas) and 3 of 6 patients were asymptomatic. There were no surgical complications and blood loss was minor in all cases. One patient, who had refused treatment for more than 40 years, presented with dyspnea and dysphagia, and required a tracheotomy for safe induction of anesthesia. Only one patient was hospitalized for more than 3 days and only one tumor recurred--as a malignant pleomorphic adenoma 3 years later.

Hyperadrenocorticism was diagnosed in 7 cats with concurrent diabetes mellitus. Four cats had pituitary adenoma with bilateral adrenocortical hyperplasia, 1 cat had pituitary carcinoma with bilateral adrenocortical hyperplasia, 1 cat had adrenocortical carcinoma, and 1 cat had adrenocortical adenoma of the left adrenal gland. One year later, adrenocortical adenoma involving the right adrenal gland also was diagnosed in this cat. Clinical signs included polyuria and polydipsia (n = 7), development of pot-bellied appearance (n = 5), dermatologic alterations (n = 5), lethargy (n = 3), weight loss (n = 3), dyspnea/panting (n = 2), and recurrent bacterial infections (n = 2). In 6 cats, the diagnosis of hyperadrenocorticism was established before death on the basis of results of the ACTH stimulation test (n = 3) and the dexamethasone screening test (n = 5). Pituitary-dependent hyperadrenocorticism was differentiated from adrenocortical neoplasia on the basis of results of the dexamethasone suppression test (n = 4), endogenous ACTH concentration (n = 3), results of abdominal radiography and ultrasonography (n = 3), and exploratory celiotomy (n = 1). Four cats died or were euthanatized without treatment attempts. Treatment with mitotane followed by 60Co teletherapy was ineffective in one cat with pituitary adenoma. One cat with pituitary carcinoma died one week after bilateral adrenalectomy. Bilateral adrenocortical adenomas were removed surgically in the affected cat.
