    Genomic characterisation of Felis catus papillomavirus type 5 with proposed classification within a new papillomavirus genus.
    Vet Microbiol 2017 Aug 2;207:50-55. Epub 2017 Jun 2.
    Biochemistry Department, Otago University, 710 Cumberland Street, Dunedin, New Zealand.
    Four Felis catus papillomavirus (FcaPV) types have been fully sequenced from domestic cats. Of these, FcaPV-2 and -3 are thought to cause feline viral plaques and Bowenoid in situ carcinomas. Two short sequences of DNA from a previously unreported PV type were amplified from a feline viral plaque using consensus PCR primers. Read More

    TdT expression in normal and neoplastic sebaceous cells.
    Histopathology 2017 Jul 5. Epub 2017 Jul 5.
    Pathology Department, Faculty of Medicine, Aristotle University of Thessaloniki, Greece.
    Aims: Terminal deoxynucleotidyl transferase (TdT) is a DNA polymerase expressed in immature, normal and neoplastic, lymphoid or hematopoietic cells and in neuroendocrine carcinomas, like Merkel cell carcinoma and small cell carcinoma. It has not yet been described in cells of epithelial origin. After observing TdT immunoreactivity in normal sebaceous glands we analyzed its spectrum of expression in cases of sebaceous cell hyperplasia and sebaceous cell neoplasms. Read More

    Managing Rhinophyma by Trimodal Therapy-Novel Approach.
    Indian J Otolaryngol Head Neck Surg 2017 Jun 5;69(2):176-180. Epub 2017 Jan 5.
    Department of Dermatology and Venereal Diseases, Rajarajeswari Medical College and Hospital, Bangalore, India.
    Rhinophyma is characterized by nodular thickening of the Nasal skin, sebaceous gland hyperplasia, dilated pores, and in its late stage, fibrosis. In severe cases, it results in loss of normal facial contours, significant disfigurement, and social isolation. Treatment options for severe rhinophyma include cryosurgery, partial-thickness decortications with subsequent secondary reepithelialisation, laser ablation, full thickness resection with graft or flap reconstruction, excision by electrocautery or radio frequency.

    Laser-Assisted Photodynamic Therapy: Two Novel Protocols for Enhanced Treatment Results.
    J Drugs Dermatol 2017 Apr;16(4):329-331

    Photodynamic therapy (PDT) uses a topical photosensitizing agent which is activated by a light source to cause destruction of specific cells. Commonly used for the treatment of actinic keratoses and photodamage, PDT can also be used for other conditions including acne and sebaceous hyperplasia. Here we report our experience with two treatment protocols. Read More

In dermatology, PDT is commonly used and approved for the treatment of oncological conditions such as actinic keratosis, Bowen disease and superficial basal cell carcinoma. In the last 2 decades however, PDT has also been used for the treatment of several nonneoplastic dermatological diseases. Read More

    Epidermal psoriasiform hyperplasia, an unrecognized sign of folliculitis decalvans: A histological study of 26 patients.
    J Cutan Pathol 2017 Apr 27;44(4):352-357. Epub 2017 Jan 27.
    Hôpital Saint-Louis, Centre Sabouraud, Paris, France.
    Background: Follicular hyperkeratosis along with hyperplasia of the follicular and interfollicular epithelia are major histopathological characteristics of hidradenitis suppurativa (HS). The presence of an occasional thickening of lesional skin in some folliculitis decalvans (FD) patients and histological similarities between FD and HS led us to look for epidermal hyperplasia and follicular hyperkeratosis in FD patients.

    Patients And Method: We performed a retrospective histological analysis of 26 patients with FD. Read More

    Carcinoid-Like/Labyrinthine Pattern in Sebaceous Neoplasms Represents a Sebaceous Mantle Phenotype: Immunohistochemical Analysis of Aberrant Vimentin Expression and Cytokeratin 20-Positive Merkel Cell Distribution.
    Am J Dermatopathol 2016 Dec 23. Epub 2016 Dec 23.

    This study investigated the nature of carcinoid-like, labyrinthine, rippled, and conventional cell arrangements in sebaceous neoplasms, focusing on vimentin expression and Merkel cell distribution in sebaceous neoplasms relative to these findings in normal sebaceous units and other sebaceous conditions. Immunohistochemistry for vimentin and cytokeratin 20 (CK20) was evaluated in carcinoid-like (n = 2), labyrinthine (n = 4), rippled (n = 3), and conventional (n = 6) sebaceomas; sebaceous mantle hyperplasia (n = 1); steatocystomas (n = 5); fibrofolliculomas (n = 4); sebaceous mantleoma (n = 1); sebaceous gland hyperplasias (n = 4); sebaceous adenomas (n = 4); and sebaceous carcinomas (n = 4) as well as normal skin tissue. The sebaceous mantle and its hamartoma (fibrofolliculoma) showed weak positivity for vimentin in the basal layer of the epithelial component and contained a few CK20-positive Merkel cells within the epithelial component, whereas mature sebaceous lobules were negative for vimentin and did not contain any Merkel cells.

    Speckle-variance optical coherence tomography: a novel approach to skin cancer characterization using vascular patterns.
    Dermatol Online J 2016 Apr 18;22(4). Epub 2016 Apr 18.
    SUNY Downstate Medical Center; New York Harbor Healthcare System; Mount Sinai Medical Center.
    Non-invasive imaging devices are currently being utilized in research and clinical settings to help visualize, characterize, anddiagnose cancers of the skin. Speckle-variance optical coherence tomography (svOCT) is one such technology that offers considerable promise for non-invasive, real time detection of skin cancers given its added ability to show changes in microvasculature. We present four early lesions of the face namely sebaceous hyperplasia, basal cell skin cancer, pigmented actinic keratosis, and malignant melanoma in situ that each display different important identification markers on svOCT.

    Linear ectopic sebaceous hyperplasia of the penis: the last memory of Tyson's glands.
    G Ital Dermatol Venereol 2016 Sep 6. Epub 2016 Sep 6.
    Clinica Dermatologica, La Sapienza University of Rome, Rome, Italy -
    Pathologists who find ectopic glands on the glans and/or on the prepuce, often describe them as Tyson's glands. In this regard, the term Tyson's glands can be replaced by two different descriptive expressions: papillomatosis corona penis and ectopic sebaceous glands. A 15-year old Caucasian male patient presented to our Institute with multiple and asymptomatic circular skin colored-to-yellowish papules at the level of the foreskin, also affecting the shaft of the penis, where they assumed a linear feature.

    Tissue injury and repair following cutaneous exposure of mice to sulfur mustard.
    Ann N Y Acad Sci 2016 Aug 2;1378(1):118-123. Epub 2016 Jul 2.
    Department of Environmental Science, New York Medical College, Valhalla, New York.
    In mouse skin, sulfur mustard (SM) is a potent vesicant, damaging both the epidermis and the dermis. The extent of wounding is dependent on the dose of SM and the duration of exposure. Initial responses include erythema, pruritus, edema, and xerosis; this is followed by an accumulation of inflammatory leukocytes in the tissue, activation of mast cells, and the release of mediators, including proinflammatory cytokines and bioactive lipids.

    Dermatol Online J 2016 Jan 15;22(1). Epub 2016 Jan 15.
    University of California Davis Medical Center, Sacramento.
    Cyclosporine-induced sebaceous hyperplasia (SH) is a well-documented entity, occurring in up to 30% of renal transplant patients treated with cyclosporine and has also been reported to occur following heart or hematopoetic stem cell transplantation (HCST). Cyclosporine has a stimulatory effect on undifferentiated sebocytes, resulting in the clinical and histologic findings in these patients. Sebaceous hyperplasia most commonly presents as asymptomatic papules over the face, chest, or groin. Read More

    Ming-Wun Wong, Ming-Joug Bair, Division of Gastroenterology, Department of Internal Medicine, MacKay Memorial Hospital, Taitung 950, Taiwan.
    Aim: To better understand some of the superficial tiny lesions that are recognized as squamous papilloma of the esophagus (SPE) and receive a different pathological diagnosis.

    Methods: All consecutive patients with esophageal polypoid lesions detected by routine endoscopy at our Endoscopy Centre between October 2009 and June 2014 were retrospectively analysed. We enrolled patients with SPE or other superficial lesions to investigate four key endoscopic appearances (whitish color, exophytic growth, wart-like shape, and surface vessels) and used narrow band imaging (NBI) to distinguish their differences.
