Histiocytoma

09/01/2000 - "One infant with a solitary lesion on the forehead was diagnosed as solitary, congenital, indeterminate cell histiocytoma because the histiocytic cells were S-100 protein positive, but meticulous ultrastructural studies did not detect Birbeck granules. "
07/01/1983 - "The cellular localization of glial S-100 protein was investigated in paraffin-embedded sections of cutaneous histiocytosis X and in a variety of cutaneous infiltrative disorders, including juvenile xanthogranuloma, necrobiotic xanthogranuloma, papular xanthoma, eruptive histiocytoma, and reticulohistiocytosis. "
06/01/2000 - "To explore the use of immunohistochemistry for this diagnostic problem, we examined the expression of S-100 protein, gp100 (the antigen recognized by HMB-45), tyrosinase (T311), Melan-A (A103), Factor XIIIa (FXIIIa), and CD68 in 10 juvenile xanthogranulomas (JXGs), five epithelioid histiocytomas (EHs), and 15 melanocytic nevi composed of large epithelioid cells.

03/01/1996 - "A non-epidemotropic, monomorphous infiltrate of vacuolated mononuclear, and occasionally multinuclear, histiocytes, positive for factor XIIIa and macrophage markers HAM56 and KiM1p, was consistent with the clinical impression of generalized eruptive histiocytomas. "
06/01/1994 - "Two of the cases were composed of cells with the same morphologic and immunohistochemical characteristics as typical epithelioid cell histiocytoma, including factor XIIIa positivity, but these arose in the reticular dermis and exhibited prominent cellularity."
02/01/1989 - "In particular approximately 50% of the constituent cells label with a polyclonal antibody directed against factor XIIIa--an antibody that labels dermal fixed connective tissue cells (fibrocytes) and cells in ordinary histiocytoma, but not the cells of Spitz or common melanocytic naevi."
01/01/1995 - "Epithelioid cell histiocytoma is a rarely reported tumor derived from factor-XIIIa-positive dermal dendrocytes. "
02/01/1989 - "The histogenesis of histiocytoma (dermatofibroma) was investigated using new antibodies that demonstrate factor XIIIa (FXIIIa) positive cells and the monocyte macrophage cell series (MAC 387), in formalin fixed tissue. "

04/15/1981 - "This "angiomatoid" lesion is closely allied to what has been termed "hemosiderin histiocytoma," which appears to be a precursor stage in its formation. "
01/01/1956 - "[Clinical aspects and histology of hemosiderin-storing histiocytoma of the skin]."
02/01/1999 - "Epithelioid cell histiocytoma differs from most benign fibrous histiocytomas in five important ways: the predominance of epithelioid cells, relative lack of secondary elements (such as giant cells, foamy, or hemosiderin-laden macrophages), relative sharp circumscription, prominent vascularity, and centering in the papillary dermis in most cases. "
11/15/1982 - "Signs of a typical histiocytoma with accumulation of hemosiderin and lipids were dominating. "
08/11/1978 - "The malignant histiocytoma is morphologically characterized by the storiform pattern of interlacing spindle cell bundles and functionally by the phagocytosis of lipids, glycogen, hemosiderin and hematoidin. "

07/01/1998 - "We have cloned and sequenced a tumor rejection antigen from a highly immunogenic rat histiocytoma, AK-5. "

10/01/1990 - "Rearrangement and overexpression of the gene coding for tumor antigen p53 in a rat histiocytoma AK-5."
01/01/1991 - "Four families of such molecules are discussed: the gp96 (hsp100) and p84/86 (hsp90) antigens of chemically induced mouse sarcomas, hsp70 antigens of tumors obtained by transfection of normal rat fetal fibroblasts with an H-ras oncogene, and the albuminoid antigens of murine melanomas and a rat histiocytoma. "
06/01/2000 - "To explore the use of immunohistochemistry for this diagnostic problem, we examined the expression of S-100 protein, gp100 (the antigen recognized by HMB-45), tyrosinase (T311), Melan-A (A103), Factor XIIIa (FXIIIa), and CD68 in 10 juvenile xanthogranulomas (JXGs), five epithelioid histiocytomas (EHs), and 15 melanocytic nevi composed of large epithelioid cells.
