    Tubulopapillary Cystic Adenoma With Apocrine Differentiation: A Unifying Concept for Syringocystadenoma Papilliferum, Apocrine Gland Cyst, and Tubular Papillary Adenoma.
    Am J Dermatopathol 2016 Dec 28. Epub 2016 Dec 28.
    *Division of Dermatology and Dermatopathology, Nippon Medical School, Musashi Kosugi Hospital, Kawasaki, Japan; †Sapporo Dermatopathology Institute Sapporo, Japan; and ‡Department of Dermatology, Nippon Medical School Tokyo, Japan.
    Syringocystadenoma papilliferum (SCAP), apocrine gland cyst (AGC, also called apocrine hidrocystoma or apocrine cystadenoma), and tubular papillary adenoma (TPA) with apocrine differentiation are defined as proliferations of apocrine epithelium with myoepithelial cells. At Sapporo Dermatopathology Institute, we retrieved 308 benign neoplastic lesions diagnosed as SCAP, AGC, or TPA and combinations of these entities. Among the 308 lesions, 202 (66%) exhibited features of only one type, of which 144 (47%) were AGC, 39 (13%) were TPA, and 19 (6%) were SCAP. Read More

    A Comparative Study of Immunohistochemical Myoepithelial Cell Markers in Cutaneous Benign Cystic Apocrine Lesions.
    Am J Dermatopathol 2016 Jul;38(7):475-83
    *Resident, Pathology, Western General Hospital, Edinburgh, United Kingdom; †Biomedical Scientist, Royal Infirmary of Edinburgh, Edinburgh, United Kingdom; and ‡Consultant Dermatopathologist, Western General Hospital, Edinburgh, United Kingdom.
    The use of immunohistochemical markers for myoepithelial cells (MEC) is a useful tool in the distinction of benign from malignant epithelial neoplasms. Although their use in breast tumors is well recognized, little is known concerning its application in comparable cutaneous lesions. Using benign cutaneous cystic apocrine lesions as a study model, the aim of this study was to compare 5 immunohistochemical markers [calponin, p63, smooth muscle actin (SMA), cytokeratin 14, and CD10] in their effectiveness to highlight MEC.

    Orbit 2011 Dec;30(6):316-7
    Department of Ophthalmology, Tulane Health Science Centre, Tulane University, New Orleans, Louisiana 70112, USA.
    Apocrine hidrocystomas are benign cysts of sweat duct origin, originating mainly from the apocrine secretory glands of Moll. They are typically encountered in the head and neck, particularly around the inner canthus of the eyelid. An intraorbital location of this lesion is extremely rare but should be considered in the differential diagnosis of a painless cystic lesion in the ocular adnexa at any age. Read More
