Airborne contact dermatitis from n-alkyl dimethylbenzylammonium chloride and n-alkyl dimethylethyl-benzylammonium chloride in a detergent.

Occupational airborne contact dermatitis from disinfectants are not frequent. They are usually seen in hospitals, were the exposure is more common. We report a case of a young woman, with an intense eczematous eruption that developed hours after an accidental contact with a cleaning solution.

[Subacute cutaneous systemic lupus erythematosus. Presentation of two clinical cases]. / Lupus eritematoso sistémico de presentación cutánea subaguda. Presentación de dos casos clínicos.

We present two cases of systemic lupus erythematosus (SLE) which began with subacute clinical manifestations. Both cutaneous and systemic lupus are the result of interactions between susceptibility genes and environmental factors such as ultraviolet radiation, giving rise to an anomalous response with hyperreactivity of T and B lymphocytes. Over 50 % of subacute cutaneous lupus cases have or will have SLE, while only 16 to 61 % of SLE cases have acute cutaneous lupus lesions.

[Nodular primary cutaneous amyloidosis associated with Sjögrens syndrome: presentation of a case]. / Amiloidosis cutánea nodular primaria asociada a síndrome de Sjögren: presentación de un caso.

Nodular primary cutaneous amyloidosis is the least frequent clinical form of the cutaneous amyloidoses. It may be associated with myeloproliferative disorders, as well as with systemic amyloidosis. Its association with other entities, such as Sjögren's syndrome, has recently been described. We present the case of a female patient with Sjögren's syndrome who developed nodular primary cutaneous amyloidosis.

Lupus eritematoso sistémico de presentación cutánea subaguda. Presentación de dos casos clínicos / Subacute cutaneous systemic lupus erythematosus. Presentation of two clinical cases

Se presentan 2 casos de lupus eritematoso sistémico (LES) que se manifestaron con síntomas cutáneos subagudos. Tanto el lupus cutáneo como el lupus sistémico son el resultado de interacciones entre genes de susceptibilidad y factores del medio, como la radiación ultravioleta, que provoca una respuesta inmunitaria anómala con una hiperreactividad de linfocitos T y B. Más del 50 % de los lupus cutáneos subagudos tienen o tendrán un LES, mientras que sólo del 16 al 61 % de los LES tienen lesiones de lupus cutáneo agudo

Amiloidosis cutánea nodular primaria asociada a síndrome de Sjögren: presentación de un caso / Nodular primary cutaneous amyloidosis associated with Sjögren’s syndrome: presentation of a case

La amiloidosis cutánea nodular primaria es la forma clínica menos frecuente de las amiloidosis cutáneas. Es posible su asociación a trastornos mieloproliferativos, así como a amiloidosis sistémica. Se ha descrito recientemente la asociación a otras entidades, como el síndrome de Sjögren. Se presenta el caso de una paciente con síndrome de Sjögren que desarrolló una amiloidosis cutánea nodular primaria

Síndrome POEMS / POEMS syndrome

El síndrome POEMS es un cuadro clínico con afectación multiorgánica que cursa con polineuropatía (P), organomegalia (O), endocrinopatía (E), componente M monoclonal (M) y manifestaciones cutáneas (S, del inglés skin). Sólo los angiomas tuberosos se consideran manifestaciones cutáneas características. Las opciones terapéuticas, entre ellas la plasmaféresis, van encaminadas a mejorar la polineuropatía, principal causa de mortalidad. Presentamos el caso de una mujer de 54 años, diagnosticada de síndrome POEMS, que desarrolló varios angiomas tuberosos en el tronco de forma eruptiva (AU)
