Spasms of the mesenteric and renal arteries are of great concern to the radiologist specialized in angiography. In most cases, they appear to be of iatrogenic origin, due to difficulties in selective catheterization and especially in superselective catheterization of the mesenteric and renal arteries. In this case, spasm may be a most unwelcome side-effect. In other less frequent cases, spasms appear as indirect signs of an underlying spasmogenic disease, such as G. I. tract
carcinoid
, pheochromocytoma, pancreatitis or poisoning such as ergotism or digitalis overdosage. Most of all, it may occur during some non-occlusive intestinal ischemias. On the other hand, spasm can be considered as a way of treatment, especially in cases of G. I. bleeding, particularly due to ulcerations.

Carcinoid tumour
of the thymus is a rare neuroendocrine tumour particularly at an advanced age. The authors report a case of a mediastinal mass in a man aged 85, the mass had remained asymptomatic for a long time. It was decided to achieve a diagnosis because the tumour was causing local compression: a mediastinal needle biopsy under computerised tomographic control confirmed that this was a
carcinoid
tumour and a study of the biopsy material using an electron microscope showed neurosecretory granules. A sternotomy enabled the tumour to be excised but a post-operative Pseudomonas pneumonia led to the death of the patient. This case underlines the diagnostic place of mediastinal needle biopsy in the presence of a mediastinal tumour. The technique can be carried out under computerised tomography or ultrasonography and this can be associated with a study of the biopsy specimen using electron microscopy which enables the diagnosis to be made before any therapeutic decisions. The treatment of choice of a
carcinoid
tumour of the thymus is surgery which confirms the tumour limits and also its thymic origin. Tumour excision can be completed using radiotherapy or even chemotherapy.

Mucoepidermoid tumours (TME) are rare tumours which develop at the level of the submucous bronchial glands of the tracheobronchial tree. The majority of these tumours develop in a benign fashion but some of them are malign. Amongst these many are probably confused with adenosquamous bronchial cancers. We have reviewed eleven patients suffering from TME who were observed over a period of twelve years. Two of these tumours were at the level of the trachea: nine others were at the level of the bronchial cartilaginous trachea. Seven of these tumours had the macroscopic and histological criteria of low grade malignancy and four corresponded to those tumours said to show high grade malignancy. The only death concerned a patient with a tracheal tumor of high grade malignancy but the death occurred immediately after laser therapy to relieve obstruction in a patient with acute asphyxia. None of the other patients died of tumour progression and the longest follow up (eleven years of survival) involved a patient with a bronchial form and a high grade malignancy with glandular invasion. Even mucoepidermoid tumours of high grade malignancy have a good prognosis and it is a cardinal point to clearly distinguish these forms from adenosquamous cancers. Nevertheless it has been suggested that adenosquamous and mucoepidermoid carcinomas could have a common origin and be the extremes of the same overall disorder just as the image we have of neuroendocrine tumours whose spectrum extends from
carcinoid
tumours to small cell cancers.

Carcinoid
cardiac disease is a common complication of metastatic
carcinoid
tumours. It is characterized by tricuspid regurgitation and pulmonary stenosis. A 68 years old woman with a metastatic
carcinoid
tumour was admitted to hospital for congestive cardiac failure secondary to severe tricuspid regurgitation. Typical carcinoid lesions of the tricuspid and pulmonary valves were observed at echocardiography. A double valve replacement was performed with a favourable outcome. Postoperative echocardiography showed a significant improvement in right ventricular function. Surgical management of
carcinoid
valvular heart disease of NYHA Stage III patients is associated with an improved 2 years survival (from 8 to 40%) despite a high operative mortality (about 27%). Cardiac surgery remains the only hope of long-term survival with a spectacular improvement in symptoms.

Recurrence after surgery for bronchial
carcinoid
tumors is very uncommon in cases of typical tumors and occasionally seen in cases of atypical tumors. We observed two cases of recurrence in an unusual location, the pleura. Somatostatin analog and MIBG scinigrams were useful for diagnosis. Treatment required surgical excision of the relapsing tumor, cytoreductive hepatic surgery or hepatic arterial chemoembolization for liver metastases, chemotherapy, interferon, radionuclide therapy, and somatostatin analogs for carcinoid syndrome.

Serotoninergic appetite-suppressant drugs, fenfluramine and dexfenfluramine, were withdrawn from the market in September 1997 on account of two major cardiopulmonary complications: primary pulmonary hypertension and valvular regurgitation. The valvular heart diseases involve mainly left-sided valves, and contrary to physiological valvular regurgitations, they appear mostly on the aortic valve. Prolonged exposure (> 3 months) appears to confer a higher risk of cardiac valve involvement. Pathological features are similar to
carcinoid
or ergot alkaloid-induced valve diseases, and suggest a common pathophysiological mechanism which would also explain pulmonary hypertension by the toxic effect of high levels of circulating serotonin. After the first reports documenting a dramatically high prevalence of valvular side effects (up to 33% according to the Food and Drug Administration), recent studies reported a lower prevalence and severity. The long-term outcome and the real incidence are unknown and require further research and epidemiological data. A clinical survey of the patients exposed to serotoninergic appetite-suppressants is necessary, to be repeated 6 to 8 months later in the absence of an initial cardiac murmur. Doppler echocardiographic examination should be performed after prolonged exposure (> 3 months) or a high dosage of these drugs, in circumstances such as the presence of cardiovascular symptoms, a cardiac murmur, or an uncertain cardiac examination because of weight of patients.

Carcinoid tumours
are the most common neuro-endocrine tumours but cardiac involvement is rarely symptomatic although often observed at post-mortem and rarely revelatory of the disease. The authors report 4 cases in which echocardiographic detection of characteristic right ventricular involvement led to the confirmation of the diagnosis of
carcinoid
tumour leading to the secondary diagnosis of the primary
carcinoid
tumour. The clinical, physiopathological echocardiographic and therapeutic characteristics of this condition are discussed.

A 68-year old woman was hospitalised because of isolated right heart failure. Doppler echocardiography revealed severe tricuspid regurgitation with thickened, shortened, hypomobile leaflets. Pulmonary valve was thickened with mild pulmonary regurgitation. Mitral and aortic valves were normal. The patient was finally diagnosed with
carcinoid
heart disease from an isolated ovarian
carcinoid
cancer without hepatic metastases. Ovarectomy was performed and the patient was considered cured of her cancer. Because of refractory right heart failure, she underwent tricuspid valve replacement with a bioprosthesis. Such cardiovascular manifestations are rarely the presenting symptoms of
carcinoid
disease. Carcinoid heart disease from ovarian primary cancer is exceptional. In this circumstance,
carcinoid
cardiac lesions may develop in the absence of hepatic metastases because the venous blood from the ovaries drains into the inferior vena cava without hepatic first past effect. Surgical resection of primary ovarian
carcinoid
tumor is often curative and the prognosis depends mainly on the cardiac condition. The diagnosis of carcinoid syndrome should be discussed in patients with organic tricuspid regurgitation without left valvular disease.

Lung cancer is a complex disease involving various oncogenic pathways. Its early detection, at pre-invasive stages, could offer the opportunity of improving the bad prognosis of this cancer. Pre-invasive stages exist for different forms of lung cancer and some of them are recognized as being preneoplastic: dysplasias and in situ carcinoma, atypical adenomatous hyperplasia and diffuse idiopathic pulmonary neuroendocrine cell hyperplasia are supposed to be precursors of squamous cell carcinomas, adenocarcinomas and
carcinoid
tumors, respectively. The sequence of histological modifications of bronchial mucosa preceding the development of a squamous cell carcinoma are well documented while those preceding other histological types are less known. This paper summarizes available data about histological modifications defining those preneoplastic and/or pre-invasive lesions, their principal clinical characteristics and the possibilities for their diagnosis. It also discusses arguments for their preneoplastic nature, their evolution and risk of progression risk, molecular abnormalities involved in lung carcinogenesis and clinical relevance of these lesions.

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is an uncommon preneoplastic condition, often associated with typical
carcinoid
tumours. The observations reported below concern two women, both suffering from chronic pulmonary symptoms. These patients underwent computed tomography that showed a solitary nodule in the first patient and multiple sub centimetre nodules in the second. In both cases histological studies of the pulmonary biopsies revealed: a proliferation of neuroendocrine cells dispersed in the bronchial and bronchiolar epithelium, more specifically superficial to the basement membrane; some tumourlets; a typical
carcinoid
tumour was also found in the first patient's biopsy. The choice of treatment remains difficult, mainly because the existing studies are restricted to small numbers of patients or isolated cases, a consequence of the low prevalence of this disease. Considering its slow evolution, management by long-term clinical, endoscopic and radiologic surveillance may be considered. If a
carcinoid
tumour is present or appears during the surveillance, the standard treatment is still surgical resection.
