A rare multi-systemic disease with less than 10 cases described in literature. Manifests in mid-adulthood with the development of telangiectasia mostly on the face, trunk and arms, as well as with erythrocytosis that may cause a red facies and occasionally, headaches. The increased serum erythropoietin levels precede the intrapulmonary shunting. The intrapulmonary shunts cause hypoxia which slowly progresses until the person needs continuous supplemental oxygen. Blood clots, probably due to erythrocytosis, and bleeding in the brain have also been reported in some affected individuals. Monoclonal gammopathy and perinephric fluid collections are usually found incidentally and do not seem to cause any complications. The syndrome has a slow and regular progression. The cause of TEMPI syndrome is currently unknown. The abnormal plasma-cell clone and/or the monoclonal gammopathy are suggested to be triggers of the disease. componente obsoleto (metadato fundacional)

A rare multiple congenital anomalies syndrome with cardiac involvement as a major feature with characteristics of QT prolongation, congenital heart defects, syndactyly, facial dysmorphism and neurodevelopmental features. There are three clinical phenotypes; the classical types that present with a prolonged QT interval and either with (Timothy syndrome 1) or without (Timothy syndrome 2) cutaneous syndactyly of fingers and toes. The atypical form (ATS) causes multi-system health concerns but not necessarily with prolonged QT. The disease is due to mutations in the CACNA1C gene (12p13.33). The clinical phenotypes correlate with genotype. Most cases arise de novo however in some cases the disease has been identified as an inherited autosomal dominant trait resulting from parental germline mosaicism. componente obsoleto (metadato fundacional)

A rare multiple congenital anomaly/intellectual disability syndrome characterised by trigonocephaly and metopic suture synostosis, dysmorphic facial features, short neck, skeletal anomalies, and variable intellectual disability. The aetiology of C syndrome is still unknown. Although most of the reported patients are sporadic, rare cases of familial occurrence have been described. componente obsoleto (metadato fundacional)

The disease presents with a wide spectrum of clinical features depending on the location, size and type of salivary gland involved, ranging from clinically asymptomatic, slow-growing, painless mass(es), that may or may not be fixed to underlying skin or muscles, to rapidly growing mass(es) associated with pain, facial weakness/nerve palsy, dysphagia, palatal/parapharyngeal fullness, nasal obstruction/bleeding, voice hoarseness/change, trismus, palate bone erosion, telangiectasia, mucosal/skin ulceration and/or cervical adenopathy. componente obsoleto (metadato fundacional)
A rare neoplastic disorder characterised by benign metastatic masses increasing in size and number after chemotherapy for non-seminomatous germ cell tumours of testis or ovary. It may present at any time after chemotherapy, with a median occurrence within 24 months after treatment completion. Per definition, the resected specimen exclusively contains mature teratoma components, and serum tumour markers have normalised. The retroperitoneum is the most common site, although almost any other localisation has been reported. Increased tumour size may cause mechanical compression of vital organs, with renal dysfunction, bowel ischaemia and biliary obstruction as major complications. componente obsoleto (metadato fundacional)

A rare neoplastic gastroenterologic disease most often found in children, which usually presents with the non-specific symptoms of a palpable mass, vomiting, abdominal pain, jaundice, and weight loss/failure to thrive. Histologically, this malignant epithelial pancreatic neoplasm of the exocrine cells has multiple lines of differentiation (acinar, ductal, mesenchymal, neuroendocrine) and the presence of squamoid nests. Pancreatoblastoma can occur in any part of the pancreas. It is a malignant embryonal neoplasm that seems to recapitulate the embryogenesis of the pancreas, presumably because it originates from the pluripotent pancreatic stem cells during foregut development. componente obsoleto (metadato fundacional)
A rare neoplastic lesion of the submucosal stroma, which can develop in any organ, often occurring in the lung, mesentery, omentum and the retroperitoneal region. It is histologically heterogenous, composed of spindle-shaped cells, myofibroblasts and inflammatory cells. It is usually benign, however local invasion, recurrence, malignant transformation with vascular invasion and metastases may occur. The presentation is nonspecific and depends on the organ involved. Some patients may present with paraneoplastic syndrome (fever, malaise, weight loss, thrombocytosis) or symptoms related to compression of adjacent organs, such as bowel obstruction. componente obsoleto (metadato fundacional)
