Melkerssons-Rosenthal syndrome: a case report and review of the literature

[New diagnostic classification of cheilitis and its clinical diagnostic pathway]

Cheilitis is a general term for various types of inflammatory diseases that occur on the lips. The etiology differs and the clinical manifestations and pathological features overlap, leading to difficulties in clinical diagnosis. Reasonable classification is conducive to the diagnosis of cheilitis. However, its classification is difficult because of its cha-racteristics. At present, scholars have proposed two different classification schemes, but a unified classification standard has not yet been established. We classified cheilitis based on its etiology, clinical manifestations, pathological characteristics, and relationship with systemic and special diseases on the basis of special medical reports and by combining clinical practice experience and summarizing previous cheilitis diagnosis and treatment literature. In accordance with this classification method, we proposed suggestions for the clinical diagnosis of cheilitis to provide a reference for the clinical diagnosis and treatment of complex cheilitis.

Melkersson-Rosenthal syndrome misdiagnosed as recurrent Bell's palsy: a case report and review of literature

Background

Melkersson–Rosenthal syndrome (MRS) is a rare neuro-mucocutaneous disorder of unknown cause, clinically characterized by a triad of recurrent facial palsy, orofacial swelling, and fissured tongue. It is frequently seen in females in their second and third decades of life. MRS is diagnosed based on clinical features and it is rarely possible to observe all the classical triad symptoms at the same time. The disorder may cause recurring peripheral facial palsy that is wrongly diagnosed as recurrent Bell’s palsy

Case presentation

A 25-year-old female patient was presented to the neurology clinic of Tikur Anbessa Specialized Hospital in Addis Ababa complaining of recurrent left-side peripheral facial weakness, facial swelling and fissured tongue of 5 days duration. Her past medical history was positive for similar symptoms, for which she was diagnosed with Bell’s palsy and received oral corticosteroid treatment. On examination left side lower facial swelling with flat naso-labial fold and fissured tongue were identified. After excluding other mimickers, she was diagnosed with Melkersson–Rosenthal syndrome and completely recovered with high dose of corticosteroid treatment.

Conclusion

Melkersson–Rosenthal syndrome may present with the classic triads of symptoms, but mostly it shows an incomplete clinical pattern. Therefore, when clinicians including allergists encountered patients with facial swelling and facial palsy, they should have to consider MRS in their differential diagnosis and specifically assess for recurrent facial palsy and fissured tongue. Unlike true angioedema, the facial swelling in MRS often develops gradually and it might cause permanent swelling with cosmetic disfigurement from multiple relapses, which can be prevented by early detection and timely initiation of treatment.

Melkersson-Rosenthal Syndrome with Orofacial Swelling and Recurrent Lower Motor Neuron Facial Nerve Palsy: A Case Report and Review of the Literature

Melkersson-Rosenthal Syndrome (MRS) is a rare otoneurologic condition, which is poorly understood and often underdiagnosed. Etiology and incidence are unclear, although infectious, inflammatory, and genetic causes have been implicated. Recurrent facial nerve palsy, facial swelling, and fissured tongue are the symptoms and signs of this condition. However, this triad is not typical in all patients as patients may present with one or more of the symptoms, which makes management of this condition difficult. Steroids may prove to be useful especially in patients who have facial nerve palsy. In this case report, we have described a 46 year-old Caucasian male who presented to the clinic for the evaluation of orofacial swelling and left facial deviation with a history of multiple treatments for recurrent lower motor neuron type facial nerve palsy.
