Detection of a large spectrum of viral infections in conjunctival pre-malignant and malignant lesions.

Int J Cancer 2020 Jun 11. Epub 2020 Jun 11.

International Agency for Research on Cancer (IARC), World Health Organization, Lyon, France.

To study the interaction between HIV and other carcinogenic infections in conjunctival squamous cell carcinoma (SCC), we evaluated the presence of a broad spectrum of human viruses in conjunctiva specimens. Beta Human papillomavirus (HPV) (n=46), gamma HPV (n=52), polyomaviruses (n=12) and herpes viruses (n=3) was determined in DNA extracted from 67 neoplastic and 55 non-neoplastic conjunctival tissues of HIV-positive and HIV negative subjects by Luminex-based assays. Next generation sequencing (NGS) was also used to further characterize the presence of cutaneous HPVs. Read More

Conjunctival Adenosquamous Carcinoma Lacks Translocation: A Variant of Squamous Cell Carcinoma With Mucoepidermoid Differentiation and Aggressive Behavior?

Int J Surg Pathol 2020 May 31:1066896920918944. Epub 2020 May 31.

Department of Pathology, Queen Elizabeth Hospital, Kowloon, Hong Kong SAR, China.

Conjunctival adenosquamous carcinoma, also known as mucoepidermoid carcinoma (MEC), is a rare tumor that preferentially affects the perilimbal area of the conjunctiva with aggressive local invasion. Consisting of infiltrative proliferation of squamous cells and mucous cells, its morphologic features are reminiscent of the salivary gland-type MEC except for the absence of intermediate cells and frequent keratin production. We reported 2 cases of conjunctival adenosquamous carcinoma and, for the first time, studied the translocation status of this rare entity. Read More

Invasive squamous cell carcinomas and precursor lesions on UV-exposed epithelia demonstrate concordant genomic complexity in driver genes.

Mod Pathol 2020 May 27. Epub 2020 May 27.

Department of Pathology, University of Michigan Medical School, Ann Arbor, MI, USA.

Although squamous cell carcinomas (SCC) are the most frequent human solid tumor at many anatomic sites, the driving molecular alterations underlying their progression from precursor lesions are poorly understood, especially in the context of photodamage. Therefore, we used high-depth, targeted next-generation sequencing (NGS) of RNA and DNA from routine tissue samples to characterize the progression of both well- (cutaneous) and poorly (ocular) studied SCCs. We assessed 56 formalin-fixed paraffin-embedded (FFPE) cutaneous lesions (n = 8 actinic keratosis, n = 30 carcinoma in situ [CIS], n = 18 invasive) and 43 FFPE ocular surface lesions (n = 2 conjunctival/corneal intraepithelial neoplasia, n = 20 CIS, n = 21 invasive), from institutions in the US and Brazil.

HIF-1α, HIF-2α, and ProExC: diagnostic or prognostic relevance in conjunctival intraepithelial neoplasia?

Graefes Arch Clin Exp Ophthalmol 2020 May 26. Epub 2020 May 26.

Eye Center, Medical Center, Faculty of Medicine, University of Freiburg, Killianstr. 5, 79106, Freiburg im Breisgau, Germany.

Purpose: The aim of this study was to investigate HIF-1α, HIF-2α, and ProExC expression in conjunctival intraepithelial neoplasia (CIN), to differentiate between metaplasia and dysplasia, and to access their value as diagnostic and prognostic immunohistochemical markers. Recurrence and progression into SCC (squamous cell carcinoma) were defined as endpoints.

Methods: Forty-three specimens including CIN I (2), CIN II (9), CIN III (29), with and without metaplasia, and metaplasia alone (3), as well as 21 conjunctival control specimens, were stained with antibodies against HIF-1α, HIF-2α, and ProExC. Read More

Conjunctival 'mucoepidermoid carcinoma' revisited: a revision of terminology, based on morphologic, immunohistochemical and molecular findings of 14 cases, and the 2018 WHO Classification of Tumours of the Eye.

Sheffield Ocular Oncology Service, Department of Ophthalmology, A-Floor, Royal Hallamshire Hospital, Sheffield, S10 2JF, UK.

In 2018, the consensus meeting for the WHO Classification of Tumours of the Eye decided that conjunctival mucoepidermoid carcinoma should be reclassified as adenosquamous carcinoma, as this represented a better morphological fit. To examine the applicability of this terminology, we studied the clinical, histopathological, immunohistochemical and molecular pathology of 14 cases that were originally diagnosed as conjunctival mucoepidermoid carcinoma. There were 7 (50%) females and 7 (50%) males. Read More

Department of Ophthalmology, University of Szeged, Szeged, Hungary.

Squamous cell papilloma (SCP) is generally a human papillomavirus (HPV) induced exophytic or endophytic proliferation on the surface of the skin, oral cavity, larynx, esophagus, cervix, vagina, and anal canal. The endophytic type SCP can cause differential diagnostic difficulties with keratoacanthoma, inverted follicular keratosis, and squamous cell carcinoma; however, these lesions are not associated with HPV infection.

Squamous cell carcinoma of the conjunctiva is associated with a number of risk factors, including HIV infection, iatrogenic immunosuppression and atopy. In addition, several studies have suggested an involvement of HPV, based on the presence of viral DNA, but did not establish whether there was active infection or evidence of causal disease association. In this manuscript, 31 cases of conjunctival in situ squamous cell carcinoma were classified as HPV DNA-positive or -negative, before being analysed by immunohistochemistry to establish the distribution of viral and cellular biomarkers of HPV gene expression.

Semin Ophthalmol 2019 1;34(7-8):465-472. Epub 2019 Aug 1.

Mark Nathaniel Thadikonda and Vijayamma Nannepaga Centre for Eye Care Education and Ophthalmic Biophysics (AM), L V Prasad Eye Institute, Hyderabad, India.

Purpose: To study the factors influencing the response to treatment with interferon alfa 2b (IFN) in ocular surface squamous neoplasia (OSSN)Methods: Retrospective study of 91 patientsResults: The mean age at presentation of patients with OSSN was 58 years (median, 60 years; range, 21 to 83 years). The mean number of clock hours of conjunctiva/cornea/limbus involvement by the tumor was 6 (median, 6; range, 1 to 12). The mean duration of topical IFN was 3 months (median, 3 months; range, 1 to 6 months) and the mean number of subconjunctival injections of IFN was 2 (median, 2; range, 0 to 6), till complete tumor regression or initiation of alternate treatment.

Ophthalmic Plast Reconstr Surg 2019 Sep/Oct;35(5):e109-e110

Department of Ophthalmology, Faculty of Medicine and Graduate School of Medicine, Hokkaido University, Sapporo, Japan.

Adenosquamous carcinoma is a highly aggressive tumor, which can rarely arise from the ocular surface. The authors herein report a patient who presented with a 5 mm mass on the temporal conjunctiva that was clinically diagnosed as squamous cell carcinoma. The lesion was surgically resected with cryopexy to the conjunctival wound edges. Read More

The burden of squamous cell carcinoma of the conjunctiva in Africa.

Cancer Epidemiol 2019 08 27;61:150-153. Epub 2019 Jun 27.

CTSU, Nuffield Department of Population Health, University of Oxford, Oxford OX3 7FL, United Kingdom; African Cancer Registry Network, 267 Banbury Road, Oxford OX2 7HT, United Kingdom.

Squamous cell carcinoma of the conjunctiva (SCCC) is a relatively common cancer in Africa, although its precise incidence and geographic distribution have not been previously systematically studied.

Methods: Using the methods employed to produce national estimates of cancer incidence for the "Globocan" series of the International Agency for Research on Cancer, along with detailed information on cancer incidence by histological subtype from cancer registries in Africa, we estimate the numbers and rates of incidence by sex, age group, country and region of Africa.

Results: We estimate that the number of new cases occurring in 2018 to be about 6 200, with all but about 50 in sub Saharan Africa, and 55% in females. Read More

Institute for Medical Epidemiology, Biometry and Informatics, Martin-Luther-University Halle-Wittenberg, Halle, Germany.

We estimate the fractions of cancer attributed to infections in Africa in 2018. The number of new cancer cases occurring was taken from Globocan2018 with some additional estimations based on data from African population-based registries. Population attributable fractions were calculated using prevalence of infection and relative risk in exposed vs. Read More
