A rare vascular disease characterised by idiopathic detachment of the layers of the walls of coronary arteries, creating a false lumen which limits the main coronary flow, leading to myocardial ischaemia. Clinical manifestations include acute coronary syndromes, especially ST-segment elevation myocardial infarction (STEMI), syncope, cardiogenic shock, or sudden cardiac death. The condition typically affects young women. |

A rare osteonecrosis characterized by bone necrosis due to disrupted blood supply in the absence of a known cause. Affected bones include the femoral head, talus, vertebral body, humerus, and scaphoid, among others. Patients may initially be asymptomatic but subsequently present with gradually developing refractory pain, swelling, and reduced range of motion. If left untreated, the condition may progress to bone collapse with secondary degeneration, fragmentation, and pathological fracture, as well as osteoarthritis. |

A rare ophthalmic disorder characterized by idiopathic orbital inflammation in which the specific target tissue is the optic nerve sheath. Patients typically present with ocular pain, pain on eye movement, visual symptoms with loss of vision progressing over several weeks, dyschromatopsia, and variable visual field defects. Orbital signs and symptoms may be present and include ptosis, ophthalmoplegia, and exophthalmos. Optic disc edema is observed in most cases. The condition is usually unilateral. |

A rare biliary tract disease characterized by loss of interlobular bile ducts resulting in chronic cholestasis, without any known cause. Loss of less than 50% of interlobular bile ducts is associated with a mild disease course, while loss of the majority of ducts results in a severe form, potentially leading to cirrhosis and liver failure. Patients typically present as young or middle-aged adults with episodic jaundice, pruritus, and elevated liver enzymes. |

A rare vascular liver disease characterized by widespread or focal cystic dilatation of sinusoidal blood-filled spaces of the liver without any known cause. Lesions can vary in diameter between few millimeters and several centimeters. The condition may remain asymptomatic or manifest with complications including rupture and intraperitoneal hemorrhage, hepatomegaly, portal hypertension, cholestasis, and liver failure. |

A rare idiopathic glomerular clinical syndrome characterized by diffuse renal lesions that are indistinguishable from the lesions observed in systemic lupus erythematosus (SLE) in the absence of circulating autoantibodies and other systemic features necessary to meet the classification criteria for SLE. Patients may present with nephrotic syndrome, abnormal urinary sediment, acute renal insufficiency, progressive glomerulonephritis, and hypertension. Some patients have been reported to develop a progression to SLE over time. |

A rare idiopathic interstitial pneumonia characterized by prominent subpleural and parenchymal fibroelastosis and pleural fibrosis, predominantly involving the upper lobes. Signs and symptoms include non-productive cough, dyspnea, and recurrent respiratory infections. Pneumothorax is a frequently reported complication. Pulmonary function test reveals a restrictive pattern and reduced diffusing capacity. Computed tomography shows pleural thickening with signs of fibrosis (traction bronchiectasis, architectural distortion, and loss of volume), and reticulation. |

A rare form of scleritis characterised by tender or painful, violet-blueish eye, with oedema and injection of deep scleral vessels, in the absence of infection or systemic autoimmune diseases. The disease may be unilateral or bilateral. Other ocular signs depend on the localisation (anterior or posterior) and on the type of scleritis (diffuse, nodular or necrotising). Extension to other layers of the eye and to peri-ocular tissues as well as visual impairment are potential complications. Idiopathic scleritis is more frequent in children than in adults. |

A rare pulmonary neuroendocrine tumor, most often presenting in women over 50 years and non-smokers, characterized by long-lasting cough (>10 years), and less frequently by dyspnea or wheezing. A proportion of patients are asymptomatic, the disease being an incidental finding during routine check-ups. Diffuse pulmonary nodules and mosaic attenuation can be detected by CT-scan however only histopathology can confirm the diagnosis detecting a multifocal hyperplasia of pulmonary neuroendocrine cells (carcinoid tumorlets). Ventilatory dysfunction can be obstructive and less often restrictive, mixed or non-specific. Symptoms can progress slowly but sometimes lead to respiratory failure. It is considered as a precursor for pulmonary carcinoid tumor. |

A rare, isolated nail anomaly characterised by brittle, thin, rough, opaque appearing nails with excessive longitudinal ridging. In a less severe form, the nails retain their luster and present with superficial ridging and multiple small geometric pits. In both varieties, superficial scaling of the nail plate and hyperkeratosis of the cuticles, as well as koilonychia and onychoschizia are observed. Any number of nails may be affected, and fingernails are more often affected than toenails. Spontaneous improvement of the condition may occur. |

A rare otorhinolaryngologic disease characterized by recurrent and severe obstruction of the central airway in the region bounded superiorly by a plane below the glottis and inferiorly by the first two tracheal rings. Symptoms may involve respiratory distress, dysphonia, exertional dyspnea, stridor, chronic cough and wheezing. Diagnosis is challenging due to the lack of apparent etiology and nonspecific respiratory symptoms that can be confounded with other common respiratory diseases and may also occur in late course of the disease. Thorough clinical and laboratory evaluation aims to exclude other causes of subglottic stenosis is therefore essential. Affected patients are almost exclusively Caucasian women between 30-60 years old. |
