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.
