Summary
A lentigo is a small, pigmented skin lesion with distinct borders, appearing at birth or later. Some types are linked to systemic issues and show basal layer hyperpigmentation.
Area of Science:
- Dermatology
- Pathology
Background:
- A lentigo is a small pigmented macule characterized by a sharply circumscribed border.
- Multiple clinical and etiologic variants of lentigines exist.
- These lesions are often identified shortly after birth but can manifest later in childhood.
Purpose of the Study:
- To describe the clinical and histological characteristics of lentigines.
- To highlight the association of certain lentigo varieties with systemic abnormalities.
Main Methods:
- Clinical identification and description of lentigo presentation.
- Histological examination of skin biopsy findings.
Main Results:
- Lentigines present as small, pigmented macules with clear borders.
- Histological findings include epidermal hyperplasia and increased basal layer pigmentation.
- Certain lentigo subtypes are associated with underlying systemic abnormalities.
Conclusions:
- Lentigines are common pigmented skin lesions with diverse presentations.
- Histopathological examination reveals characteristic epidermal changes.
- Clinical awareness is crucial for identifying potential systemic associations.
