Overview
Simple lentigo refers to a benign, hyperpigmented skin lesion typically found in adults, often presenting as solitary or multiple flat, brown spots. 1Diagnosis
Clinical Presentation: Hyperpigmented papules or plaques 1.
Diagnostic Confirmation: Histopathological examination via biopsy is definitive 1.
Differential Diagnosis: Consider other hyperpigmented conditions like seborrheic keratoses or melasma.
Special Considerations: Generalized lentigo (leopard syndrome) involves systemic features including sensorineural deafness, growth retardation, and ocular changes like premature cataracts 2.Management
Primary Treatment: No specific treatment required for simple lentigo; reassurance and monitoring are often sufficient.
Cosmetic Interventions: Laser therapy or chemical peels may be considered for cosmetic improvement 1.
Systemic Involvement: For generalized lentigo, manage associated conditions such as cataracts and cardiac defects as indicated 2.Special Populations
Pediatrics: Generalized lentigo can present in childhood with systemic manifestations 2.
Comorbidities: Patients with generalized lentigo may require multidisciplinary management addressing ocular, cardiac, and skeletal issues 2.Key Recommendations
Biopsy is essential for definitive diagnosis of simple lentigo to rule out other conditions 1 (Evidence: Strong).
Monitor for systemic features in cases suspected of generalized lentigo to manage associated complications effectively 2 (Evidence: Moderate).
Cosmetic treatments like laser therapy can be considered for patients seeking aesthetic improvement 1 (Evidence: Expert opinion).References
