Novel Viruses: Update on the significance of papillomavirus infections in cats.

J Feline Med Surg 2018 Nov 27:1098612X18808105. Epub 2018 Nov 27.

University of Sydney, Faculty of Science, Sydney School of Veterinary Science, NSW 2006, Australia.

Practical Relevance:: Prior to 1990 papillomaviruses (PVs) were not recognised to infect or cause disease in domestic cats. Since this time, the use of histology, immunohistochemistry and, more recently, molecular techniques has revealed that PVs almost certainly cause feline viral plaques and Bowenoid in situ carcinomas, oral papillomas and feline sarcoids. In addition, there is increasing evidence that PVs play a significant role in the development of feline cutaneous squamous cell carcinomas, one of the most common skin cancers of cats. Read More

May P Chan

Arch Pathol Lab Med 2018 Sep 11. Epub 2018 Sep 11.

From the Department of Pathology, University of Michigan Health System, Ann Arbor.

Context: - Histologic distinction between condyloma acuminatum and various benign and malignant condyloma-like lesions in the anogenital area poses a common diagnostic challenge to pathologists across subspecialties.

Objective: - To review the overlapping and distinguishing features of condyloma acuminatum and its mimics, and to clarify confusing terminology and diagnostic criteria for problematic entities.

Data Sources: - A review of the literature on condyloma acuminatum (ordinary and giant types), verrucous carcinoma, warty/warty-basaloid high-grade squamous intraepithelial lesion and squamous cell carcinoma, papillary squamous cell carcinoma, bowenoid papulosis, verruca vulgaris, epidermolytic acanthoma, and verruciform xanthoma was performed.

Use of fluorescence in situ hybridization to detect Felis catus papillomavirus type 2 in feline Bowenoid in situ carcinomas.

J Feline Med Surg 2018 Sep 4:1098612X18795919. Epub 2018 Sep 4.

1 School of Biomedical and Veterinary Sciences, Murdoch University, Perth, Australia.

Objectives Papillomaviruses (PVs) are ubiquitous host- and site-specific viruses. PV infections in cats are associated with oral papillomas, viral plaques, Bowenoid in situ carcinomas (BISCs), squamous cell carcinomas and sarcoids; this association is primarily based on PCR detection of PV DNA within said lesions. PV DNA is frequently detectable on normal feline skin; thus, it is possible that some of the implicated DNA is commensal rather than associated with lesion formation. Read More

The depth of follicular extension in actinic keratosis correlates with the depth of invasion in squamous cell carcinoma: implication for clinical treatment.

J Eur Acad Dermatol Venereol 2018 Oct 23;32(10):1657-1661. Epub 2018 Mar 23.

Department of Pathology, Hospital Universitari Germans Trias i Pujol, Universitat Autònoma de Barcelona, Badalona, Spain.

Background: Actinic keratosis (AK) may show extension down follicles, not only in cases with full-thickness epidermal atypia ('bowenoid' AK), but also in cases with atypia limited to the epidermal basalis. Previous studies have demonstrated that, in bowenoid AK, follicular extension is usually superficial, being limited to the upper follicular segment. Little is known about the depth of follicular involvement in cases of invasive squamous cell carcinoma of the skin (iSCC) arising from AK and the role of the follicle in iSCC pathogenesis. Read More

Linear ectopic sebaceous hyperplasia of the penis: the last memory of Tyson's glands.

G Ital Dermatol Venereol 2018 Jun 6;153(3):429-431. Epub 2016 Sep 6.

Laboratory of Dermatopathology, San Gallicano Institute, 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.
