Acantosis pigmentaria - Symptom

Síntomas:

La acantosis pigmentaria por lo regular aparece de una manera lenta y no causa ningún síntoma distinto a los cambios en la piel.

Finalmente, la piel oscura y aterciopelada con marcas y pliegues muy visibles aparece en las axilas, en la ingle y en los pliegues del cuello, al igual que sobre las articulaciones de los dedos de las manos y de los pies.

Con menos frecuencia, se pueden ver afectados los labios, las palmas de las manos, las plantas de los pies u otras áreas. Estos síntomas son más comunes en personas con cáncer.

Signos y exámenes:

Usualmente, el médico puede diagnosticar la acantosis pigmentaria observando la piel. En casos inusuales, se puede necesitar una biopsia de piel.

Si no existe una causa clara de la acantosis pigmentaria, puede ser necesario hacer exámenes. El médico puede solicitar exámenes de sangre, una endoscopia o radiografías para descartar la diabetes o el cáncer como la causa.
