Giant-cell reticulohistiocytoma
Giant-cell reticulohistiocytoma (pronunciation: jai-ant-sel ret-ic-u-lo-his-tee-o-cy-to-ma) is a rare type of histiocytoma, a benign tumor that originates from the histiocyte cells.
Etymology
The term 'Giant-cell reticulohistiocytoma' is derived from the Greek words 'gigas' meaning 'giant', 'kutos' meaning 'cell', 'histio' meaning 'tissue', and 'oma' meaning 'tumor'. 'Reticulo' is derived from the Latin word 'reticulum' meaning 'network', referring to the network-like structure of the cells involved in this condition.
Definition
Giant-cell reticulohistiocytoma is a benign neoplasm characterized by the presence of large, multinucleated histiocytes and fibroblasts. It is a rare form of non-Langerhans cell histiocytosis.
Symptoms
The most common symptom of giant-cell reticulohistiocytoma is the presence of a solitary, slow-growing, painless nodule or tumor on the skin. The tumor is usually found on the hands, feet, or face, but can occur anywhere on the body.
Diagnosis
Diagnosis of giant-cell reticulohistiocytoma is typically made through a biopsy of the tumor. The biopsy is examined under a microscope to identify the characteristic giant cells and fibroblasts.
Treatment
Treatment for giant-cell reticulohistiocytoma typically involves surgical removal of the tumor. In some cases, radiation therapy or chemotherapy may be used if the tumor cannot be completely removed.
