Melkersson-Rosenthal syndrome with coeliac and allergic diseases

A 45-year-old man presented with a 10-year history of relapsing oedema of the lips. Moreover, he exhibited recurrent facial nerve palsy since the age of 10 years, coeliac disease since the age of 12 years, atopic eczema, allergic rhinitis and asthma. Physical examination revealed lip swelling and lingua plicata. Thus, he presented the classic triad of Melkersson-Rosenthal syndrome which includes recurrent orofacial oedema, facial nerve palsy and fissured tongue. A lip biopsy confirmed our clinical diagnosis.This case is particularly rare, as the classic triad is seen only in a minority of the cases. Moreover, allergic and coeliac diseases were observed concomitantly. This paper illustrates a potential pathophysiological interconnection between these pathologies in which interferon gamma could play a key role. To our knowledge, this is the first case report in which Melkersson-Rosenthal syndrome has been observed concurrently with coeliac disease.
