Nail problems prompt dermatologist visits, affecting individuals of all ages. The nail organ comprises the matrix, bed, plate, and fold. Thorough examination of nails during physical assessments can reveal localized issues requiring treatment or hint at underlying systemic conditions necessitating further inquiry. Assessment methods encompass clinical examination, dermatoscopy, imaging, microbiological (including mycological) tests, and histological analysis. Nail responses typically fall into a few categories: idiopathic disorders, infections, cancers, and drug-induced reactions. Among these, around half arise from infections, 15% from inflammatory or metabolic factors, and 5% from malignancies and pigment alterations. This diverse landscape of nail disorders necessitates comprehensive evaluation techniques for accurate diagnosis and appropriate intervention.
