Lentigines are common, benign lesions of hyperpigmentation that occur on different areas of the body with an increasing incidence in older adults. Lentigines are very common in fair skinned and older individuals who have experienced chronic sun exposure. There are variations of lentigines; the most common variation in the geriatric age group is solar lentigines. While genetic variations and air pollution might play contributory roles, ultraviolet radiation (UVR) remains the key physiological trigger. Diagnostic techniques encompass clinical evaluation, dermatoscopy, and histopathology. The prognosis is good with a combination of procedural and topical therapies being used for cosmetic reasons. Understanding the risk factors, including age, fair skin, sun exposure, and history of sunburns, is crucial for preventing and managing lentigines. Although benign, lentigines sometimes indicate the presence of underlying syndromes like Peutz-Jeghers syndrome, Carney Complex, and LEOPARD syndrome, which variations are more common in younger individuals. Overall, an interdisciplinary approach combining dermatological knowledge, patient history, and innovative therapies is essential for effective management of lentigines.
