The clinical presentation of multicentric reticulohistiocytosis is insidious in onset and begins with arthritic complaints in approximately two thirds of patients. It is potentially one of the most rapidly destructive forms of arthritis. Joint involvement remits and relapses, gradually worsening into a debilitating and permanent arthritis multilans. The severity of the damage has been reported to be related to the age of onset; therefore, the earlier one has symptoms, the more severe the symptoms tend to be. Like the associated arthritis, skin lesions tend to wax and wane until the disease spontaneously resolves, but may leave permanent disfigurement.
This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
