[Multicentric reticulohistiocytosis: histochemical, histoenzymatic and immunocytochemical study].
Report of a case of multicentric reticulohistiocytosis with clinical, histopathologic, histochemical and immunohistochemical study. Neutral mucins and lipids were demonstrated in the cytoplasm of dermal histiocytes. The monocyte-histiocytic nature of the cells was shown by means of acid phosphatase, ATP-ase, muramidase and alpha-1-antitrypsin. Due to the immunohistochemical results, the relationship with Langerhans cells was rejected. No secretory activity of immunoglobulins was shown and the proliferation qualified as benign. The cells among the histiocytic population were typified as mature T lymphocytes.
