Making Nails Sexy Again

Managing challenging nail conditions requires a high index of suspicion, particularly for longitudinal melanonychia in adults, where a single pigmented nail necessitates investigation to exclude melanoma. Biopsy procedures, such as matrix shaves or punches, should target the origin of the pigment, while monitoring for change remains critical over three to six months. Retronychia, characterized by proximal nail growth and inflammation, functions as a foreign body response often linked to repetitive trauma or improper footwear; intervention involves topical steroids or partial nail avulsion. Chronic onycholysis frequently stems from irritant exposure rather than underlying disease, requiring rigorous avoidance of soaps and water to facilitate reattachment. These clinical strategies emphasize identifying etiology—such as systemic medications or biomechanical factors—to guide appropriate surgical or conservative management for patients with refractory nail disorders.
