Phenotype and clinics

age at onset is variable; more frequently: young adults or children

two types of elementary cutaneous lesions are observed :
- persistant papule-like warts, isolated, or confluent with a psoriasic aspect
- white spots, pityriasis versicolor-like
both types of lesions are localized mainly on the outer part of the hands, on foreharms, legs, face, trunk and perianal zone.

immunodeficiency: decreased immune response of T lymphocytes to mitogens, decreased humoral response to Human Papilloma Virus antigens; EV lesions have been described in renal transplant recipients.

various Human Papilloma Virus (HPV) subtypes are regularly detected in the cutaneous lesions: HPV 5, 8, 9, 12, 14, 15, 17, 19, 25, 36, 38, 47, 50.

patients are simultaneously affected by differents HPV subtypes, according to disease localisation; these subtypes are different from those observed in common warts (HPV 2, 3, 4, 10).

Neoplastic risk

risk of malignant transformation of cutaneous lesions is within a delay of 20 to 30 yrs (very slow process comparable to the genital carcinogenesis associated with high risk HPVs)

cytology: squamous cell carcinoma (spinocellular or basocellular carcinoma, Bowen disease).

correlation with oncogenic subtypes of HPV found in the transformed lesions: HPV 5, 8, 14; the most frequent subtypes are HPV 5 and 8 (90% of cases).

benign familial forms are associated with HPV 3, without malignant evolution.

HPV-5 is present in the macular lesions.

probable potentialisation by UV ligth: 25 to 30% of malignant lesions localised to the face and forehead (hypothetic role of P53 mutations).

protein E6 and\/or E7 (tumor suppressor function) from HPV seem to be involved in the malignant transformation.

Treatment

surgical resection of localized lesions; chemotherapy with Acitretin (25 mg\/j) for multifocal lesions.

Evolution

local recidives, enhanced by UV exposition.

Genes involved and Proteins

Complementation groups

genes and proteins are unknown.
