[CD30 positive pilotropic lymphoma].

BACKGROUND: We report an unusual case of cutaneous CD30-positive lymphoma with pilar tropism and circulating Sezary cells which had a rapidly fatal course. CASE REPORT: A 78-year-old man presented erythematous infiltration of the face, a pruriginous eruption on the trunk and proximal portions of the limbs with small erythematopurpuric follicular papulae, and node enlargement in the inguinal and axillary areas. The rest of the clinical examination was normal. Circulating Sezary cells were found in significant numbers on two different blood smears. Histologic and immunohistochemistry examination of a skin biopsy evidenced medium to large sized lymphoid cell infiltration in a perifollicular localization. A few small cells penetrated the pilar apparatus. There was no follicular mucinosis. The tumoral cells expressed CD2, CD3, CD4 and 75 p. 100 were positive for CD30. Node aspiration showed lymphomatous cells and CD3+ and CD30+ lymphomatous infiltration was found on marrow smears. A T clone was evidenced both in blood and bone marrow leading to the diagnosis of pilotropic CD30-positive lymphoma. Chlorambucil and prednisone were given. The patient died 5 months later. DISCUSSION: The cytology findings suggest medium to large cell pleomorphic lymphoma. The circulating Sezary cells, the pilotropic eruption, and the rapidly fatal outcome suggest transformation of a Sezary syndrome into CD30-positive large cell lymphoma which has been described in fungoid mycosis.

[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.

[Atypical manifestations in familial type 1 Waardenburg syndrome].

BACKGROUND: Waardenburg syndrome is an uncommon genetic disorder. Four clinical types are recognized. Three responsible genes have been identified (PAX 3: for type I syndrome, MITF and EDN3 for types II and IV respectively). CASE REPORT: We report the case of a patient with Waardenburg type I morphotype who had atypical neurological manifestations. Decisive elements for diagnosis were the presence of Waardenburg syndrome in the family and, in affected kin, a mutation causing a shift in PAX 3 gene reading. DISCUSSION: This case confirms the variability of Waardenburg signs within one family. The association of unusual neurological manifestations in the proband suggested that Vogt Koyanagi Harada disease may have been associated and may show some relationship with familial Waardenburg syndrome.

[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.
