RESUMO

Pityriasis lichenoides chronica (PLC) is an infrequent dermatosis of unknown aetiology, wholse evolution and response to treatment differs between children and adults. When PLC is recalcitrant or unresponsive to topical treatment, phototherapy is one of the main treatments used. We carried out a prospective study of adult diffuse PLC treated with narrowband ultraviolet B (NB-UVB). We treated eight patients whose disease showed no response to topical therapy, and obtained a complete response rate of 88% in a mean of 23 sessions (cumulative dose 16.99 J/cm2 ). However, the relapse rate was 43% in the first 6 months. Our results are similar to those of other published studies but there is much variability between them in the doses applied and the number of sessions needed. Further studies are necessary to devise a protocol for NB-UVB treatment of PLC.

RESUMO

Chronic infantile neurologic cutaneous articular (CINCA) syndrome is a serious chronic systemic inflammatory disease that presents at a young age and that is characterized by skin, joint, and central nervous system disease. Skin symptoms are the first to appear, in the form of a longstanding nonpruritic urticarial rash, with exacerbations coinciding with episodes of fever, arthritis, and enlarged lymph nodes. The findings of biopsy of skin lesions are extremely variable but characterized by perivascular neutrophilic infiltrate. With the discovery of mutations in the CIAS1 gene, which encodes a protein known as cryopyrin, this entity has been classified as one of the cryopyrin-associated autoinflammatory diseases, along with familial cold urticaria and Muckle-Wells syndrome. This discovery has also made available new therapeutic options. We present the case of a boy diagnosed with CINCA syndrome who presented with an outbreak of painful skin lesions and fever. These lesions were thought to be an exacerbation of underlying lesions during an episode of fever.

RESUMO

Atypical mycobacterial infections are increasingly important in immunosuppressed patients as well as in healthy hosts. The atypical mycobacterium that most commonly affects the skin is Mycobacterium marinum. The infection should be suspected upon the presence of ulcers, nodules or chronic plaques and a history of contact with fresh or salt water. Optimal therapy is yet to be established. We report a case of Mycobacterium marinum infection in a patient receiving immunosuppressive therapy that responded favourably to treatment with doxicycline. We review the different antibiotic regimens prescribed in the past years for the treatment of Mycobacterium marinum infection.

RESUMO

El síndrome CINCA (Chronic Infantile Neurologic Cutaneous Articular Syndrome) es una grave enfermedad inflamatoria sistémica crónica, de instauración temprana, que se caracteriza por afectación cutánea, articular y del sistema nervioso central (SNC). La clínica cutánea en forma de exantema urticariforme no pruriginoso es la primera en aparecer, siendo más o menos permanente con exacerbaciones que coinciden con brotes de fiebre, artritis y adenopatías. La biopsia de las lesiones cutáneas es muy variable, aunque destaca un infiltrado neutrofílico perivascular. El descubrimiento de mutaciones en el gen CIAS1, que codifica una proteína llamada criopirina, ha permitido añadir esta entidad al espectro de las enfermedades autoinflamatorias asociadas a criopirinas, junto con la urticaria familiar por frío y el síndrome de Muckle-Wells, implicando además nuevas opciones terapéuticas. Presentamos el caso de un varón diagnosticado de síndrome CINCA que presentó un brote de lesiones cutáneas dolorosas y fiebre, interpretándose éstas como una exacerbación de sus lesiones habituales durante un episodio febril (AU)

RESUMO

Los agentes de revelado fotográfico son derivados de la parafenilendiamina, que pueden actuar como irritantes y/o sensibilizantes cutáneos en trabajadores de procesos fotográficos, manifestándose las lesiones no sólo en forma de eczema de contacto, sino también como lesiones liquenoides. La incidencia de dermatosis profesionales por reveladores de color ha disminuido en los últimos años debido a la automatización de los procesos de revelado y a la aparición de la fotografía digital. Presentamos un caso de dermatitis de contacto liquenoide secundaria al revelador CD2 en un trabajador de laboratorio fotográfico automatizado que ocasionalmente reparaba las averías que se presentaban en la maquinaria. Las lesiones eran clínica e histológicamente liquenoides y las pruebas epicutáneas resultaron positivas a CD2. Nuestro caso presenta además la particularidad de la diseminación de las lesiones hacia zonas donde no era evidente el contacto con el líquido revelador


Colour developing agents, derivatives of paraphenylendiamine, can be both irritants and sensitizers in photographic processing workers. They cause allergic contact dermatitis and also lichenoid reactions. The incidence of occupational dermatosis from colour developers has decreased in the last years because of the automation in the developer processing and the emergence of digital photography. We present a case of lichenoid contact dermatitis in a mechanized photographic laboratory worker, who occasionally repaired machinery's damages. Lesions were clinical and histhopatological lichenoid and patch test were positives to CD2. Our case presents the singularity of the dissemination of the lesions to areas of the skin where it was not evident the contact with the colour developers agents
