Reticulohistiocytosis
Reticulohistiocytosis
Reticulohistiocytosis (pronunciation: re-tic-u-lo-his-ti-o-cy-to-sis) is a rare disorder characterized by the accumulation of histiocytes, a type of immune cell, in the skin and other organs.
Etymology
The term "Reticulohistiocytosis" is derived from the Latin words 'reticulum' meaning 'net', 'histio' meaning 'tissue', and 'cytosis' meaning 'condition of cells'.
Definition
Reticulohistiocytosis is a rare non-Langerhans cell histiocytosis characterized by the accumulation of histiocytes in the skin and other organs. The disease can present in a variety of forms, including solitary cutaneous reticulohistiocytosis, multicentric reticulohistiocytosis, and diffuse cutaneous reticulohistiocytosis.
Symptoms
Symptoms of reticulohistiocytosis can vary widely, but often include skin lesions, joint pain, and in severe cases, organ dysfunction.
Diagnosis
Diagnosis of reticulohistiocytosis typically involves a combination of physical examination, medical history, and laboratory tests. A biopsy of affected tissue may also be performed to confirm the diagnosis.
Treatment
Treatment for reticulohistiocytosis is typically aimed at managing symptoms and may include medications to reduce inflammation and slow the progression of the disease. In severe cases, surgery may be required to remove large or problematic lesions.
