Review Case Reports
[Rare manifestations of monoclonal gammopathies: About two clinical cases and literature review].
Monoclonal gammopathies are common over the age of 50. Patients are usually asymptomatic. However, some patients present with secondary clinical manifestations, which are now grouped under the entity « Monoclonal Gammopathy of Clinical Significance » (MGCS). ⋯ The discovery of a decrease in von Willebrand activity (vWF:RCo) or angioedema in a patient over 50 years of age, in the absence of a family history, should prompt a search for a hemopathy and in particular, a monoclonal gammopathy.

Relapsing polychondritis is a rare systemic disease. It usually begins in middle-aged individuals. This diagnosis is mainly suggested in the presence of chondritis, i.e. inflammatory flares on the cartilage, in particular of the ears, nose or respiratory tract, and more rarely in the presence of other manifestations. ⋯ Specific strategies are required if relapsing polychondritis is associated with myelodysplasia/VEXAS. Forms limited to the cartilage of the nose or ears have a good prognosis. Involvement of the cartilage of the respiratory tract, cardiovascular involvement, and association with myelodysplasia/VEXAS (more frequent in men over 50years of age) are detrimental to the prognosis of the disease.
