Antiretroviral-responsive confluent and reticulated papillomatosis: a case report of an unusual association.

Oxf Med Case Reports 2019 Oct 31;2019(10):omz099. Epub 2019 Oct 31.

Faculty of Health & Life Sciences, De Montfort University, Leicester LE1-9BH, UK.

This is the case of a 29-year-old male newly diagnosed with advanced HIV (CD < 35cells/mm), presenting to us with hyperpigmented and scaly non-pruritic macules over his chest and upper abdomen of several weeks duration. Woodlamp examination was negative, but a skin biopsy suggested confluent and reticulated papillomatosis (CRP). Given his lack of any of the condition's identifiable triggers and the unusually rapid resolution of his lesions shortly after antiretroviral therapy initiation, an immunodeficiency-related etiology for his CRP was entertained.

Dermatol Online J 2019 Mar 15;25(3). Epub 2019 Mar 15.

Texas A & M University College of Medicine, College Station, Texas.

Epidermodysplasia verruciformis (EV) is an autosomal recessive genodermatosis characterized by susceptibility to beta-genus human papillomavirus (HPV) infection. Owing to TMC6/EVER1 and TMC8/EVER2 mutations that lead to abnormal transmembrane channels in the endoplasmic reticulum involved in immunological pathways, keratinocytes cannot combat infection from non-pathogenic HPV strains. Mutations involving RHOH, MST-1, CORO1A, and IL-7 have also been associated with EV in patients without TMC6 or TMC8 mutations. Read More
