[Palmoplantar filiform parakeratotic hyperkeratosis and digestive adenocarcinoma].

Introduction: There are very few observations of filiform palmo-plantar hyperkeratosis reported. Nevertheless it's worth knowing this entity for his potential association with a visceral neoplasia.
Case Report: We report the first case of filiform palmo-plantar hyperkeratosis associated with a digestive adenocarcinoma and a polycystic kidney disease.
Discussion: After a review of palmar and plantar filiform hyperkeratosis in the literature, we will discuss the possible association with neoplasia or other pathologies. This pathology requires a strict clinical and paraclinical follow-up.
