Flare and change of psoriasis morphology during the course of treatment with tumour necrosis factor blockers.

Tumour necrosis factor (TNF) blockers represent an exciting advance in the management of psoriasis. However, the safety profile of these drugs is not completely established. We present a review of the literature, and report on eight patients: two with the unexpected appearance of psoriasis, and the remaining six with exacerbation and change in morphology of their existing psoriasis, all of which occurred during treatment with the TNF blockers adalimumab, etanercept and infliximab. The two new cases, neither of whom had any personal or family history of psoriasis, developed pustular psoriasis on the palms and/or soles. The other six patients, previously diagnosed with severe chronic plaque psoriasis (four patients), generalized pustular psoriasis (one) and erythrodermic psoriasis (one), developed eruptive guttate psoriasis between 15 days and 18 months after the beginning of therapy. These patients had never before presented guttate-type psoriatic lesions, and the lesions appeared in areas of the body that were free of psoriatic plaques at baseline.

[Juvenile multiple xanthogranuloma in a patient with Langerhans cell histiocytosis].

We present the case of a 10-week-old girl who had erythematous papules with a yellowish hue from birth with diagnosis of Langerhans cell histiocytosis, that was accompanied by a lytic lesion in the skull and hepatic involvement. After several months of treatment with prednisone and vinblastine with skin and systemic improvement, several rounded erythematous papules with a yellowish hue appeared in the right cheek. The biopsy showed a histiocytic infiltrate with positivity for CD68 and negative staining for S100 and CD1a, with a final diagnosis of juvenile xanthogranuloma. This association has been previously described in the literature in few cases. Although several hypotheses have been suggested, the causal relationship between both entities has still not been demonstrated.

Sweet's syndrome on the area of postmastectomy lymphoedema.

BACKGROUND: Sweet's syndrome (SS) has been reported in association with many conditions, including malignancy, infections, autoimmune disorders, pregnancy and drugs. MATERIALS AND METHODS: We reviewed patients with SS-like lesions on the lymphoedema area seen in our department. Clinical manifestations, histopathologic characteristics, treatment and outcome data were recorded and analysed. RESULTS: We report seven women with a history of surgery for breast cancer with axillary lymphadenectomy. Six of them were on tamoxifen. All of them had various lesions consistent with SS localized predominantly on the limb affected by the postmastectomy lymphoedema, and on the ipsilateral chest, trunk and back. One of them presented bullous lesions. Three of the cases underwent spontaneous remission, two resolved with antibiotic therapy, one healed with corticosteroids, and one with corticosteroids plus antibiotic. CONCLUSIONS: Erythematous tender plaques on the area of postmastectomy lymphoedema could be considered an unusual manifestation of Sweet's syndrome. We have found only three similar cases in the literature. Although it is difficult to elucidate the pathogenesis of this entity, it has been suggested that it could be due to immune surveillance impairment.
