Abstract

Papillary Intralymphatic Angioendothelioma or Dabska’s tumor is very rare tumor in children and young adults, characterized by intraluminal papillary endothelial structures which are lined by plump cuboidal endothelial cells with hobnailed appearance [1]. It usually develops in the soft tissues of extremities. Deeper locations are exceptional and unusual, complicating its early diagnosis and adequate management.In this paper we report a new case about a recurrent and locally invasive oropharyngeal Dabska’s tumor in a 34-year-old Moroccan woman.
