Plummer's nail is a clinical sign in which there is onycholysis, or separation of the nail from the nail bed, particularly affecting the ring and little fingers. It occurs in patients with thyrotoxicosis.[1] About 5% of hyperthyroid patients display abnormal nail changes.[2] Plummer's nail is also associated with psoriasis, traumatic injury, and allergic contact dermatitis.[3]
The sign is named after Henry Stanley Plummer.[citation needed]
