Identification of Common Nail and Skin Disorders

Narrative ReviewThe following review discusses the more common disorders of the perionychium and skin likely to be observed by the hand therapist. To assist the therapist in recognition of abnormalities, the anatomy, physiology, and basic function of the normal nail unit are described. Indications of when disorders of the nail, resulting from trauma, infections, and neoplasms, require referral to another practitioner are discussed. Characteristics of abnormal skin conditions are described with an emphasis on differentiating benign from malignant lesions. By knowing the suspicious characteristics of nail and skin disorders, the upper extremity therapist can positively impact the well-being of his or her patients through quick referral, leading to early diagnosis and treatment of potentially serious disease.Level of Evidence5.
