[Photosensitive prurigo in AIDS].

INTRODUCTION: A case of photosensitive prurigo during AIDs is reported. This is the second case in the literature. We discuss the relations between HIV infection and photodermatoses. OBSERVATIONS: A woman, known to be HIV seropositive from 1990, developed during the spring 1990 a prurigo on light exposed areas who received the next year. A photobiological investigation was performed, showing a polymorphic light eruption induced by UVB. DISCUSSION: Patients infected with HIV have a high prevalence of UV radiation responsive skin diseases. On the other hand, UVA radiations, UVB and UVC have been shown to induce activation and replication of HIV. PUVA therapy and UVB therapy have shown their efficacity in the treatment of many photodermatoses associated with HIV infection, without any worsening of the illness. Many questions are not yet solved in the relationship between HIV and photosensitivity and the photobiological investigation should be more frequently done.

[Erythema multiforme caused by saquinavir].

BACKGROUND: Saquinavir is a protease inhibitor used for the treatment of HIV infection. Adverse skin reactions have been rare. We report here the first case of erythema multiforme in a patient given saquinavir. CASE REPORT: A 32-year-old man was seropositive for HIV and consulted due to the development of round maculo-papular lesions centered on a bulla and two erosive lesions of the palate five days after the introduction of saquinavir. Histology was compatible with erythema multiforme. After withdrawal of saquinavir, the skin and mucosal lesions regressed in 15 days, with no recurrence at 3 months. DISCUSSION: Adverse skin reactions to saquinavir are exceptional (eruptions, pruritus). We describe here the first case of erythema multiforme caused by saquinavir (imputability criteria 12 BO). Due to the structural analogy of saquinavir with other protease inhibitors (indiravir, ritonavir, nelfinavir) it would be difficult to prescribe a compound of the same class.

[Syphilitic labial leucokeratosis].

BACKGROUND: Several diagnoses, including syphilis, can be entertained in patients with leukokeratosis of the buccal mucosa. We report a case of labial leucokeratosis which revealed latent syphilis. CASE REPORT: A 36-year-old man with a past history of genital syphilis chancre which have been treated 12 years earlier, developed buccal leucokeratosis with no other clinical manifestation. Histology showed dermal infiltration containing plasma cells, polynuclears and lymphocytes. Blood tests were positive for syphilis. Complementary examinations were unable to detect another localization. Leucokeratosis regressed completely after one injection of Extencilline. There has been no recurrence at one year. DISCUSSION: The clinical and histological presentations of syphilis can mimic different skin diseases. Serodiagnosis alone is significant. Isolated buccal lesions are rarely described in syphilis suggesting serodiagnosis should always be ordered. Whatever the clinical stage of the diseases, serological surveillance after treatment for syphilis is essential.

[Recurrent phototriggered summer light eruption of the axillary and inguinal area: an atypical topographic form of benign summer lucitis].

UNLABELLED: INTRODUCTION This case report of benign summer light eruption emphasizes the importance of phototests in the diagnosis of photosensitive dermatoses. CASE REPORT: A 25-year-old man, phototype II, had experienced a pruriginous papulovesicular erythematous eruption of the axillary and inguinal regions each summer for 12 years. A high-dose UV phototest (40 J/cm2 x 3 days) directed on the right posterior axillary area and a whole body exposure test (4 J/cm2 UVA, 20 mJ/cm2 UVB x 3 days) were positive both clinically and histologically on day 4. DEM B was normal at 26 mJ/cm2. Iterative polychromatic phototest (DEM x 3 days) in the area usually involved (left posterior axillary region) was negative. The simple UVA (13 J/cm2) and iterative phototests performed on the back were negative. The results of the phototests led to the diagnosis of benign light eruption despite the unusual localization. DISCUSSION: The diagnosis of benign light eruption is generally clinical. Phototests are unnecessary in most cases. Benign light eruption can be triggered by high-dose iterative UVA exposure of the susceptible area or whole body phototests (UVA-UVB). These specific phototests are indicated in atypical forms or localizations in order to determine the course of benign light eruption and to uncover simulations.

Shave excision and phenol peeling of generalized verrucous epidermal nevus.

BACKGROUND: Generalized verrucous epidermal nevus is a disorder characterized by papulokeratotic and verrucous plaques involving a large area of the skin. This disease has been associated with a number of malformations including osseous, neurological, and ophthalmologic anomalies. OBJECTIVE: To report clinical and histologic features of verrucous epidermal nevus that developed in association with osseous anomalies, and the surgical technique employed. METHODS: Treatment consisted of razor blade shaving using a dermatome, followed by phenol peeling on the pigmented areas of the face. RESULTS: The described procedure resulted in a cure of the verrucous epidermal nevus with good cosmetic outcome. CONCLUSION: Generalized verrucous epidermal nevus can be successfully managed by surgical excision using a razor blade mounted on a dermatome.
