Abstract

Dermatomyositis (DM) is a dermatomyopathy with a broad spectrum of features, defined by Bohan et al as an objective set of clinical and laboratory criteria. Dermatomyositis has been associated with extracutaneous neoplasias, especially with ovarian carcinoma.

The term “punctate keratoderma” comprises a group of diseases with different etiologies characterized by small hyperkeratotic lesions usually scattered in palms and soles. Punctate porokeratotic keratoderma (PPK) is a type of punctate keratoderma mainly defined by its peculiar histological features, including the presence of cornoid lamella similar to the one observed in porokeratosis. Punctate porokeratotic keratoderma has been considered a sporadic disease although some rare paraneoplastic cases have been published.

We report for the first time a case of dermatomyositis with typical features of punctate porokeratotic keratoderma, both as paraneoplastic presentation of ovarian carcinoma. Its paraneoplastic nature is clearly demonstrated by the clinical improvement observed following tumor excision.

Key words:
dermatomyositis
ovarian carcinoma
paraneoplastic syndrome
punctate keratoderma
Resumen

La dermatomiositis (DM) es una dermatomiopatía con un amplio espectro de manifestaciones, definido por Bohan et al como un conjunto objetivo de criterios clínico-analíticos. La DM se ha relacionado con neoplasias extracutáneas, especialmente con carcinoma ovárico.

El término queratodermia punctata incluye un grupo de enfermedades con diferentes etiologías, caracterizadas por lesiones hiperqueratósicas de pequeño tamaño, habitualmente salpicadas en palmas y plantas. La queratodermia poroqueratósica punctata (QPP) es un tipo de queratodermia punctata definida principalmente por sus peculiares características histopatológicas, incluyendo la presencia de lamela cornoide, similar a la observada en la poroqueratosis. La QPP ha sido considerada una enfermedad esporádica; sin embargo se ha publicado algún caso raro paraneoplásico.

Presentamos por vez primera un caso de DM con datos típicos de QPP, ambas como manifestaciones parane-oplásicas de un carcinoma ovárico. Su naturaleza paraneoplásica es claramente demostrada por la mejoría clínica observada tras la extirpación de la neoplasia.
