In 19 cases in which myeloperoxidase was negative, all marked with CD68 and CD43. We propose that decreased expression of CD117 and its downstream events in melanocytes may be initiated by cytotoxic effects of melanosomal-antigen-specific CD8+ neoplastic T lymphocytes, resulting in destabilization of CD117 and leading to dysfunction and/or loss of melanocytes in the epidermis of hypopigmented mycosis fungoides.

At least 1 section per cm diameter. Binding of SCF leads to dimerization of 2 KIT receptors, leading to downstream signal transduction, In general, the 3 types of melanomas enriched with, Aberrations include: increased copy number, amplification or specific mutations, Specific mutations are only detectible through sequencing of relevant exons (9, 11, 13, 17 and 18) (, For melanoma, using CD117 as a marker for KIT overexpression is NOT reliable and should NOT be used, To date, there has been no significant discordance between primary and metastatic, Sequencing of exons 9, 11, 13, 17 and 18 is performed, Imatinib is a tyrosine kinase inhibitor used to treat multiple neoplasms including: CML (Ph+), advanced GIST, ALL (Ph+), DFSP and others, Evidence from multiple phase II trials suggests that only certain, Exon 11 contains the mutation L576P while exon 13 contains K642E; these are the 2 most commonly identified, Ipilimumab, a monoclonal antibody which targets CTLA4, is another drug which shows some promise in melanomas known to be enriched with, Ipilimumab decreases inhibition of cytotoxic T cells and increases their ability to destroy cancer cells, Resistance mechanisms in melanoma have not been well documented as the evaluation of imatinib is only in phase II trials, Criteria defining resistance have not been established (, In GIST, up to 50% of patients treated with imatinib develop resistance, Resistance mechanisms include: tyrosine kinase switching, resistance in wild type KIT, amplification and overexpression, efflux of imatinib by cells and acquired secondary, Future studies and clinical trials will evaluate responses with KIT inhibitors, Patients with GIST who demonstrate resistance on imatinib are either treated with dose escalation or an alternative tyrosine kinase inhibitor (, Other KIT inhibitors used include nilotinib, dasatinib and sorafenib. It is more sensitive B. In the present study we analysed … Epub 2016 Jul 26. Gastroin-testinal stromal tumors (GISTs): CD117, DOG-1 and PKCθ expression.
