Rosai-Dorfman disease with diffuse gastrointestinal involvement

Abstract

Rosai-Dorfman disease, formerly known as sinus histiocytosis with massive lymphadenopathy', is a rare self-limiting histiocytic proliferative disorder typically presenting early in life with cervical lymphadenopathy and nonspecific systemic symptoms. Although it is usually a nodal disease, extranodal lesions may be encountered in some cases. The gastrointestinal tract is uncommonly affected in Rosai-Dorfman disease and its diagnosis depends on clinical suspicion and careful histopathological examination of biopsy samples taken from involved gastrointestinal segments. Here, we report a case of atypical Rosai-Dorfman disease with systemic symptoms and diffuse gastrointestinal involvement that led to a diagnostic and therapeutic challenge.
