Hello and welcome to HCM,
Histiocytes are macrophage
like cells present ubiquitously in all body tissues.
Histiocytes play a role in the defense mechanism of the body.
They are present in the lymph
nodes and cause sinus histiocytosis
Histiocytes are also present in the skin.
Proliferation of these cells in the skin can cause skin lesion.
The nature of the skin lesions can only be confirmed after skin biopsy
Proliferation of histiocytes in the skin biopsy will confirm the neoplastic process of the histiocytes.
Appropriate drug (anti-metabolite) can be instituted after diagnosis of the skin lesions by biopsy.
Thanks and take care
Dr Shailja P Wahal
