RESUMEN
A 63-year-old female patient, with a past history of rheumatoid arthritis, presented with insidious pain on the left foot second and third metatarsophalangeal joints, associated with swelling and morning stiffness (mean time: four hours). Physical examination evidenced a tender and soft nodularity in the third intermetatarsal space, along with sharp pain, consistent with Morton's neuroma. Foot ultrasound suggested Morton's neuroma, but not excluding the possibility of rheumatoid arthritis involvement. Foot magnetic resonance imaging suggested the possibility of extensive synovitis of the third metatarsophalangeal joint, but not excluding the coexistence of Morton's neuroma because of the mass effect. Finally, the patient underwent an ultrasound-guided needle biopsy of the nodule, which confirmed metatarsophalangeal joint synovitis. The foot is a common location of rheumatoid arthritis manifestation, and metatarsophalangeal joint synovitis can mimic Morton's neuroma. After a definite diagnosis, the patient recovered lower limb functional impairment after introducing adalimumab and a rehabilitation program. This case highlights the importance of an accurate differential diagnosis, pharmacological rheumatoid arthritis control, and physical medicine and rehabilitation programs to optimal clinical and functional improvement.
RESUMEN
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.
