[Cutaneous carcinoma and papillomavirus 5. Discovered during prolonged UVA photochemotherapy].

INTRODUCTION: HPV 5 is an opportunistic oncogenic virus found mainly in patients with verruciform epidermodysplasia or in certain immunodepressed patients. CASE: We report the case of a 48-year-old patient who developed, over a 5 year period, 30 skin carcinomas after prolonged puvatreatment. HPV 5 was identified. The course has been stable under treatment with etretinate and alpha-interferon. COMMENTS: The role of ultraviolet irradiation as a carcinogenic agent is raised by this observation, both as a primary factor and as a local factor favouring immunosuppression and proliferation of opportunistic HVP.

Photosensitive and phototriggered pityriasis rubra pilaris.

We report a 59-year-old man with photosensitive and photodistributed pityriasis rubra pilaris. The phototriggering of the lesions was obtained by the iterative polychromatic phototest (3 times the minimal erythema dose (MED) on 3 consecutive days) and was also observed on the supra MED sites, which began the 10th day and persisted several months. Our results are comparable to those already obtained in photosensitive psoriasis, which helped us to identify the clinical similarities of photosensitivity in these two instances of dermatosis.

[Vulvar lichen sclerosus].

Lichen sclerosus's pathogeny, the most frequent vulvar dystrophy predominant at the start of menopause, is still enigmatic. Its repercussions on the functional level can be disabling. Its clinical sides include atrophy and sclerosis. The evolution of the past towards great atrophies (kraurosis vulvae) may today be prevented by early diagnosis and treatment (essentially dermocorticoïde). Even if the risk of degenerescence is low, it's not negligible and these patients must be put under steady surveillance.

Pili torti with congenital deafness (Bjornstad syndrome): a case report.

We report Bjornstad syndrome in a 5-year-old girl with severe bilateral congenital loss of hearing and pili torti. The mode of inheritance of this rare syndrome seems to be heterogeneous. A maternal uncle of the patient was deaf from birth and his hair had shown the same abnormalities at the same age; an autosomal recessive transmission can be assumed.

Contact allergy to 3-(4' methylbenzylidene) camphor and contact and photocontact allergy to 4-isopropyl dibenzoylmethane.

We report a clinical case of a 15-year-old boy who presented a photodistributed eruption after having used a sunscreen cream for 8 days. Photobiological testing showed a contact allergy to 3-(4' methylbenzylidene) camphor (Eusolex 6300) included in his sunscreen cream associated with a contact and photocontact allergy to 4-isopropyl-dibenzoylmethane (Eusolex 8020) not included.
