Z Orosz
Histopathology, 34(6), 517-525 (1999-06-26)
The purpose of this study was to test different malignant non-melanocytic tumours with the commercially available antibody Melan-A to examine its diagnostic specificity and to compare the S100, Melan-A and HMB-45 reactivity in various melanocytic lesions. Seventy-three benign and malignant
R Bergman et al.
Journal of the American Academy of Dermatology, 42(3), 496-500 (2000-02-25)
The histopathologic differential diagnosis of Spitz nevus (SN) from malignant melanoma (MM) may be difficult. We attempted to elucidate the pattern of expression of a newly recognized melanocyte-specific melanosomal protein MART-1 in routinely processed specimens of SNs, MMs, and ordinary
R P Perez et al.
Human pathology, 31(11), 1381-1388 (2000-12-09)
Melanoma inhibitory activity (MIA) is a small soluble protein secreted by malignant melanoma cells and chondrocytes. Prior studies suggested that MIA expression was relatively tissue-specific, making it a potentially useful marker for melanoma. The current investigations sought to more clearly
P G Coulie et al.
The Journal of experimental medicine, 180(1), 35-42 (1994-07-01)
It has been reported previously that antitumor cytolytic T lymphocyte (CTL) clones can be isolated from blood lymphocytes of HLA-A2 melanoma patients, after stimulation in vitro with autologous tumor cells, and that some of these CTL clones lyse most HLA-A2
Hadi Yaziji et al.
International journal of surgical pathology, 11(1), 11-15 (2003-02-25)
While historically detection of premelanosomes by electron microscopic studies was the only means possible of confirming melanocytic lineage of a neoplastic process, advances in the field of immunohistochemistry have allowed for accurate and reliable diagnosis using antibodies to 1 of
Cynthia Kucher et al.
The American Journal of dermatopathology, 26(6), 452-457 (2004-12-25)
Desmoplastic melanoma (DMM) is an uncommon melanoma variant with a distinct morphology, including a prominent spindle cell component with fibrosis, as well as a distinct immunohistochemical profile. Histologically, the spindle cell component of DMM can be confused with sclerotic/desmoplastic nevi
Ravi Suchak et al.
The American Journal of dermatopathology, 36(5), 387-391 (2014-01-08)
To assess the usefulness of routine melan-A immunohistochemistry (IHC) for exclusion of microinvasion in lentigo maligna (LM). One hundred and twenty cases of LM from our archives were reviewed by 2 authors with S100 protein and melan-A IHC using a
T Kageshita et al.
Journal of immunotherapy (Hagerstown, Md. : 1997), 20(6), 460-465 (1997-12-31)
Twenty-eight primary and 29 metastatic melanoma lesions and 18 pigmented nevi lesions were analyzed by using the immunoperoxidase reaction with anti-MART-1 and anti-gp100 monoclonal antibodies (mAbs). The MART-1 was expressed in 28, 29, and 18, and gp100 was expressed in
Y Kawakami et al.
Proceedings of the National Academy of Sciences of the United States of America, 91(9), 3515-3519 (1994-04-26)
By cDNA expression cloning we have isolated a gene encoding a shared human melanoma antigen recognized by HLA-A2 restricted autologous and allogenic tumor-infiltrating lymphocytes (TILs) from patients with metastatic melanoma. By using both transient and stable expression systems, transfection of
M P Hoang et al.
Journal of cutaneous pathology, 28(8), 400-406 (2001-08-09)
Recurrent melanocytic lesions may histologically resemble malignant melanoma. We evaluated the original nevi (ON) and recurrent nevi (RN) of 15 patients by routine histology and immunohistochemistry (IHC), examining expression of S-100 protein, gp100 (with HMB-45), MART-1, tyrosinase, and the Ki-67
S Mocellin et al.
Journal of immunotherapy (Hagerstown, Md. : 1997), 24(6), 447-458 (2002-01-05)
Assessment of antigen expression by solid tumors has relied predominantly on immunohistochemistry, flow cytometry, and more recently quantitative real-time polymerase chain reaction. However, all these techniques present intrinsic limits. The laser scanning cytometer, by combining the properties of light and
P A Fetsch et al.
Cancer, 87(1), 37-42 (1999-03-30)
HMB-45, an antibody directed against a premelanosome glycoprotein, has thus far been considered the most specific antibody for the immunocytochemical substantiation of the diagnosis of malignant melanoma (MM). A recently described antigen, MART-1, is a transmembrane protein that is present
Patricia Switten Nielsen et al.
The American Journal of dermatopathology, 33(4), 361-370 (2011-05-26)
Distinction between benign and malignant melanocytic lesions may be difficult by today's methods, even for highly skilled dermatopathologists, emphasizing the need for improved diagnostic tools. We have studied the discriminative abilities of immunohistochemical (IHC) double stains using the IHC markers
Klaus Helm et al.
Journal of cutaneous pathology, 35(10), 931-934 (2008-05-23)
Distinguishing lentigo maligna from solar lentigo, and pigmented actinic keratosis can sometimes be problematic. Melan-A is an immunohistochemical marker which that can be helpful in decorating the melanocytes of pigmented lesions. A recent report has suggested that Melan-A may spuriously
