    GATA3 and MYB Expression in Cutaneous Adnexal Neoplasms.
    Am J Dermatopathol 2017 Apr;39(4):279-286
    *Departments of Pathology, Porto Medical School and Sao Joao Hospital, Porto, Portugal; †Departments of Pathology, William Beaumont School of Medicine, Royal Oak, MI; ‡Departments of Pathology, Duke University Medical Center, Durham, NC; and §Departments of Pathology, Harvard Medical School and Massachusetts General Hospital, Boston, MA.
    Knowledge of staining pattern of certain immunostains might be useful in the classification of cutaneous adnexal tumors that can have clinical importance. We studied GATA3 and MYB expression in archival materials of 220 adnexal tumors comprised of sebaceous carcinomas, follicular tumors, apocrine carcinoma, predominantly apocrine tumors, predominantly eccrine tumors, and others including adenoid cystic carcinomas. Nuclear GATA3 expression was seen in 70% (153/220) of cases, including sebaceous carcinoma (93%), apocrine carcinoma (93%), follicular neoplasms (100%), and predominantly apocrine neoplasms (69%), yet only 38% of predominantly eccrine neoplasms.

    p40 in Conjunction With CK20 and E-Cadherin Distinguishes Primary Adnexal Neoplasms of the Skin.
    Appl Immunohistochem Mol Morphol 2016 Jul;24(6):414-21
    Institute of Pathology, University Hospital RWTH Aachen, Aachen, Germany.
    Although basal cell carcinomas (BCC) show typical histomorphologic features, they sometimes remain difficult in distinction from benign adnexal skin tumors of follicular origin like trichoepithelioma (TE) or trichoblastoma (TB). Consequently, an immunohistochemical marker panel separating described entities would be helpful in clinical routine. Thus, we stained 22 skin lesions (BCC, TE, and TB) against β-catenin, CK20, E-cadherin, p40, and p63. Read More

    CYLD GeneticTesting for Brooke-Spiegler Syndrome, Familial Cylindromatosis and Multiple Familial Trichoepitheliomas.
    PLoS Curr 2015 Feb 19;7. Epub 2015 Feb 19.
    Department of Dermatology, Royal Victoria Infirmary, Newcastle upon Tyne, UK; Institute of Genetic Medicine, Newcastle University, Newcastle upon Tyne, UK.
    The clinical presentation of multiple, rare, skin appendage tumours called cylindromas has been attributed to germline mutations in the tumour suppressor gene CYLD (OMIM 605018). Brooke-Spiegler Syndrome (BSS), familial cylindromatosis (FC) and multiple familial trichoepitheliomas (MFT) (OMIM #605041, #132700, #601606 respectively) differ due to the types of other skin appendage tumour seen together with cylindroma, such as spiradenoma and trichoepithelioma. Previously thought to be separate entities, they are now viewed as allelic variants with overlapping phenotypes, supported by mutation analysis of CYLD . Read More
