| Popis: | Background: Epidermodysplasia verruciformis (EV) is a rare autosomal-recessive disorder characterized by widespread and persistent infection with human papilloma virus (HPV) and a risk of malignant degeneration. Most cases of EV are caused by mutations in the two EV genes, EVER1/TMC6 and EVER2/TMC8. The clinical presentation of EV takes two different forms, which coexist in most cases. Over a period of years, patients develop plane warts and pityriasis versicolor-like lesions. Sixteen cases of EV in HIV-positive patients have been clinically investigated and reported in the literature. However, different inherited susceptibilities towards HPV infection in immunodeficient patients, like HIV-positive patients, have only rarely been addressed. Observation: We describe a 22-year-old female patient with a congenital HIV infection, who presented with slowly progressing and confluent erythematous papules on her hands and hypopigmented macules on her extremities. The histopathology was typical for EV, and HPV5 was detected by PCR and reverse hybridization. The 44-year-old HIV-positive mother has no typical EV lesions. The patient is homozygous for an A to T single nucleotide polymorphism (SNP) at position 917 of the TMC8/EVER2 gene. The mother of the patient is heterozygous for this SNP. Conclusion: These results support the hypothesis that the combination of immunodeficiency and a susceptibility allele may contribute to the differences in occurrence of EV in HIV-positive patients. |
