Immunoreactivity of human tissue mast cells (TMCs) was studied in one case of solitary mastocytoma of the skin, three cases of malignant mastocytosis, and in six lymph nodes with reactive intrasinusoidal increase of TMCs. Immunohistochemically, TMCs reacted positively to antisera against vimentin, common leukocyte antigen (CLA), lysozyme, alpha 1-antitrypsin (alpha 1-AT), and alpha 1-antichymotrypsin (alpha 1-ACT) and to a monoclonal antibody (KiB3) that detects preferentially B-lymphocytes. Additionally, strong positive reactions to polyclonal antisera against adrenocorticotropic hormone (ACTH) and human peptide histidine isoleucine (PHI) and weaker reactions to antisera against leu-enkephalin and met-enkephalin were observed; all other antisera tested yielded negative results. Positive stainings for vimentin, CLA, alpha 1-AT, alpha 1-ACT, and lysozyme further support the hypothesis that human TMCs may be related to the myeloid-monocytic system. The positive reactivity of TMCs to antisera against ACTH, PHI, leu-enkephalin, and met-enkephalin has not been reported previously. These findings suggest that TMCs are able to store and/or produce regulatory peptides in addition to many other well-known, granule-bound mediators.

D008198	Lymph Nodes	They are oval or bean shaped bodies (1 - 30 mm in diameter) located along the lymphatic system.	Lymph Node,Node, Lymph,Nodes, Lymph
D008407	Mast Cells	Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR.	Basophils, Tissue,Basophil, Tissue,Cell, Mast,Cells, Mast,Mast Cell,Tissue Basophil,Tissue Basophils
D008415	Mastocytosis	A rare neoplastic disorder characterized by a clonal proliferation of MAST CELLS, associated with KIT-D816 mutations, and accompanied by aberrant mast cell activation. The abnormal increase of MAST CELLS may occur in only the skin (MASTOCYTOSIS, CUTANEOUS), in extracutaneous tissues involving multiple organs (MASTOCYTOSIS, SYSTEMIC), or in solid tumors (MASTOCYTOMA).
D009369	Neoplasms	New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.
