An uncommon onychomadesis in adults

Onychomadesis can be attributed to a wide variety of causes, including allergic contact dermatitis, paronychia,pustular psoriasis, and trauma, and most cases are considered to be idiopathic. Onychomadesis at the same level involving several nails suggests a systemic cause, such as fever, erythroderma, use of drugs such as anti-tumoral chemotherapeutics, carbamazepine, lithium salts, retinoids and, at the infantile age, viral infections such as Kawasaki disease, and hand, foot, and mouth disease (HFMD). HFMD generally affects children younger than 10 years old and in adults has minor manifestations and thereby easily goes unrecognized.
