    Perianal Pagetoid Intraepithelial Carcinoma.
    Case Rep Gastroenterol 2017 Jan-Apr;11(1):109-113. Epub 2017 Mar 3.
    aDivision of Radiation Oncology, The Ottawa Hospital and the University of Ottawa, Ottawa, Ontario, Canada.
    Extramammary Paget disease (EMPD) involving the perianal region is rare and challenging to manage. Primary EMPD involves stand-alone noninvasive lesions within the epidermis, while secondary EMPD involves phenotypically similar lesions derived from separate underlying malignancies. Differentiating between primary and secondary EMPD is challenging when no underlying malignancies are detected during workup. Read More

    Intratumor dihydropyrimidine dehydrogenase mRNA expression levels are decreased in extramammary Paget's disease.
    Drug Discov Ther 2017 Jun 11. Epub 2017 Jun 11.
    Department of Dermatology and Plastic Surgery, Faculty of Life Sciences, Kumamoto University.
    S-1, a 5-fluorouracil (5-FU)-based anti-cancer agent, is an important drug for treating metastatic extramammary Paget's disease (EMPD). Although intratumor expression levels of 5-FU metabolism enzymes have been studied widely in many solid tumors, no studies have examined on the expression levels of thymidylate synthase (TS), orotate phosphoribosyl-transferase (OPRT) or dihydropyrimidine dehydrogenase (DPD) in skin cancers. The aim of this study was to estimate the intratumoral mRNA expression levels of these genes in EMPD by real time PCR. Read More

    Invasive Extramammary Paget Disease of the Vulva With Signet Ring Cell Morphology in a Patient With Signet Ring Cell Carcinoma of the Stomach: Report of a Case.
    Int J Gynecol Pathol 2017 Jun 2. Epub 2017 Jun 2.
    Department of Pathology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.
    This report describes a rare case of invasive extramammary Paget disease of the vulva with signet ring cell morphology in a 58-yr-old woman with a history of signet ring cell carcinoma of the stomach. This case was initially misinterpreted as a metastatic gastric carcinoma to the vulva because an initial small, superficial biopsy specimen showed infiltration of signet ring cells in the dermis without intraepidermal Paget cells. However, a surgically resected specimen showed concordant immunophenotypes in both intraepidermal Paget cells and intradermal signet ring cell components with immunoreactivity to cytokeratin (CK) 7, CEA, and gross cystic disease fluid protein-15, and immunonegativity for CK20, MUC5AC, and MUC6.

    Handheld Reflectance Confocal Microscopy for the Detection of Recurrent Extramammary Paget Disease.
    JAMA Dermatol 2017 May 10. Epub 2017 May 10.
    Dermatology Service, Department of Medicine, Memorial Sloan Kettering Cancer Center, New York, New York.
    Importance: Extramammary Paget disease (EMPD) is commonly refractory to surgical and nonsurgical therapies. Identifying recurrent or persistent EMPD is challenging because the disease is multifocal, and multiple blind scouting biopsies are usually performed in this setting. Handheld reflectance confocal microscopy (HRCM) has been used to diagnose and map primary EMPD and therefore may be used to identify EMPD recurrences. Read More

    Vulvar and Anal Intraepithelial Neoplasia: Terminology, Diagnosis, and Ancillary Studies.
    Adv Anat Pathol 2017 May;24(3):136-150
    Department of Pathology, Stanford University School of Medicine, Stanford, CA.
    Currently, it is recognized that there is an HPV-related and an HPV-independent pathway to developing squamous cell carcinomas (SCC) in the anus and vulva. The majority of precursor lesions and SCC in the anus and vulva are high-risk HPV-associated, with HPV16 the most common type. Given the morphologic overlap and biological equivalence of HPV-related preinvasive squamous lesions of the lower anogenital tract, a unified, 2-tiered histopathologic nomenclature is now recommended.

    Perianal and Vulvar Extramammary Paget Disease: A Report of Six Cases and Mapping Biopsy of the Anal Canal.
    Ann Dermatol 2016 Oct 30;28(5):624-628. Epub 2016 Sep 30.
    Department of Surgical Oncology, The University of Tokyo Hospital, Tokyo, Japan.
    Treatment of perianal and vulvar extramammary Paget disease (EMPD), rare intraepithelial malignancies, is often challenging because of its potential to spread into the anal canal. However, there is still no consensus regarding the optimal resection margin within the anal canal. Between 2004 and 2014, six patients (three with perianal EMPD and three with vulvar EMPD) in which the spread of Paget cells into the anal canal was highly suspected were referred to our department.

    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.

    A case of Extramammary Paget's Disease (EMPD) involving the cervix mimicking cervical carcinoma on routine cervical cytology in a 66-year-old woman with a history of recurrent multifocal EMPD involving the vulva, perineum, perianal area, and rectum is reported. The patient had undergone multiple excisions and reconstructions of EMPD, however, had a benign cervical smear history and reported no vaginal bleeding. The conventional papanicolaou smear was reported as concerning for carcinoma with abundant, well preserved material illustrating highly atypical cells with anisonucleosis and dense cytoplasm and focal microacini.

    A proposal for a TNM staging system for extramammary Paget disease: Retrospective analysis of 301 patients with invasive primary tumors.
    J Dermatol Sci 2016 Sep 3;83(3):234-9. Epub 2016 Jun 3.
    University of Tsukuba, Japan.
    Background: Although extramammary Paget disease (EMPD) usually appears as carcinoma in situ, it sometimes becomes invasive (iEMPD) and fatal. However, a TNM staging system for iEMPD has yet to be established.

    Objective: The aim of this study was to establish a TNM staging system for iEMPD. Read More

    Concordance of the HER2 protein and gene status between primary and corresponding lymph node metastatic sites of extramammary Paget disease.
    Clin Exp Metastasis 2016 Oct 11;33(7):687-97. Epub 2016 Jun 11.
    Department of Dermatologic Oncology, National Cancer Center Hospital, Tokyo, Japan.
    Recent studies have reported the overexpression of human epidermal growth factor receptor 2 (HER2) in primary extramammary Paget disease (EMPD). These results indicate that therapies that target HER2 may be useful in treating metastatic EMPD, for which the prognosis is poor. However, there is limited information on the expression and gene amplification of HER2 in metastatic EMPD. Read More

    RANKL expression is a useful marker for differentiation of pagetoid squamous cell carcinoma in situ from extramammary Paget disease.
    J Cutan Pathol 2016 Sep 20;43(9):772-5. Epub 2016 Jun 20.
    Department of Dermatology, Tohoku University Graduate School of Medicine, Sendai, Japan.
    Background: Pagetoid squamous cell carcinoma in situ (SCCIS) is a histopathologic variant of SCCIS composed of cells that display an abundant, pale-staining cytoplasm in a pagetoid distribution within the epidermis. As pagetoid SCCIS is sometimes difficult to differentiate from extramammary Paget disease (EMPD) histopathologically, specific markers for pagetoid SCCIS or EMPD are needed by dermatopathologists.

    Methods: In this report, we employed immunohistochemical staining for receptor of activated nuclear factor kappa ligand (RANKL) and programmed death-ligand 1 (PD-L1) in six cases each of pagetoid SCCIS and EMPD. Read More
