Owing to disease progression, she was started on ixabepilone, a mitotic inhibitor. Read More

    Enlightening the Pink: Use of Confocal Microscopy in Pink Lesions.
    Dermatol Clin 2016 Oct;34(4):443-458
    Medicine and Medical Specialities Department, Medicine and Health Sciences Faculty, Alcalá University, Univeristy Campus, National road II, 28871- Alcalá de Henares, Madrid, Spain; Dermatology Service, Memorial Sloan-Kettering Cancer Center, 16 E 60th Street, New York, NY 10022, USA.
    Solitary pink lesions can pose a particular challenge to dermatologists because they may be almost or completely featureless clinically and dermoscopically, previously requiring biopsy to exclude malignancy. However, these lesions usually are not particularly challenging histopathologically. Thus, the incorporation of in vivo reflectance confocal microscopy into the clinical practice, which allows for noninvasive examination of the skin at the cellular level revealing features previously seen only on histopathology, is particularly useful for this subset of clinically difficult lesions.

    Paget's disease of the male breast in the 21st century: A systematic review.
    Breast 2016 Oct 6;29:14-23. Epub 2016 Jul 6.
    Department of Pathology and Laboratory Medicine, University of Saskatchewan, Royal University Hospital, 103 Hospital Drive, Saskatoon, Saskatchewan S7N 0W8, Canada. Electronic address:
    Paget's disease of the breast is characterized by eczematous changes of the nipple-areolar complex and is associated with an underlying in situ or invasive breast carcinoma in most cases. Histologically, Paget's disease is identified by epithelial cells with abundant basophilic or amphophilic, finely granular cytoplasm with a large, centrally situated nucleus, most abundant in the lower epidermal layers. Due to the rarity of the condition among breast cancers, compounded by the rarity of breast cancer in men, understanding of the disease's presentation, course, and optimal treatment in men is largely derived from case reports and extrapolation of findings from studies in female patients.

    Pathol Res Pract 2016 Apr 22;212(4):279-81. Epub 2016 Jan 22.
    Department of Pathology, Yale University School of Medicine, PO Box 208023, New Haven, CT 06520-8023, USA. Electronic address:
    Pathologists should be aware of the existence of a rare CK7-negative variant of breast carcinoma in general, and of Paget's disease in particular. Cytokeratin 7-negative Paget's disease and CK7-negative ductal intraepithelial neoplasia (ductal carcinoma in situ) present a major diagnostic challenge for pathologists since there is limited awareness of their existence. When there is classic Paget's morphology on H&E sections, GATA3 positivity should resolve any doubts about the diagnosis in the setting of a CK7-negative neoplastic cell population. Read More
