Histiocytic disorders are a group of rare diseases with systemic involvement and with multiple clinical manifestations. We present the case of a 51 years old patient investigated for dyspnea with orthopnea, dry cough, asthenia, muscular weakness and ataxia. The association of previous symptoms with skin lesions, diabetes insipidus, partial hypophyseal insufficiency and pericarditis induced many diagnostic debates. The diagnosis is Histiocytosis X must be sustained by tissue biopsy with immunohistochemical assay or genetic testing. The particularity of our patient is the presence of pericarditis, rarely associated with histiocytosis. Collaboration between medical specialties is mandatory in order to treat this disorder.

Histiocytoses are rare diseases characterised by infiltration of affected organs by myeloid cells with a monocyte or dendritic cell phenotype. Symptoms can range from self-resolving localised forms to multisystemic lesions requiring specific treatment. To demonstrate extremely rare cases of CD68-negative cardiac histiocytosis with expression of SARS-CoV-2 antigen in infiltrate cells.

Erdheim-Chester Disease (ECD) is a rare form of histiocytosis characterized by xanthomatous infiltration of affected organs. We present a case of a 62-year-old man with ECD initially presenting with constrictive pericarditis. Comprehensive imaging revealed systemic involvement, including the skeleton, orbit, pituitary, lung, kidney, and retroperitoneum, despite the absence of related symptoms.
