    Area of Science:

    • Dermatology
    • Pigmentary Disorders
    • Histopathology

    Background:

    • Pigmentary disorders involve melanocyte abnormalities.
    • Epidermal melanocytosis is characterized by epidermal melanocytes.
    • Acromelanosis progressiva is a rare condition with progressive hyperpigmentation.

    Observation:

    • A 2-year-old Puerto Rican boy presented with peculiar jet-black patches of pigmentation on his right hand fingers.
    • Clinical and histologic examinations were performed.
    • The patient was followed for a 2-year period.

    Findings:

    • The observed condition shares similarities with acromelanosis progressiva.
    • A key difference was the lack of disease progression over the 2-year follow-up.
    • The condition is considered an epidermal manifestation of pigmentary disorders.
