    Area of Science:

    • Dermatology
    • Oncology
    • Histopathology

    Background:

    • Longitudinal pigmented bands on nails can be caused by various conditions, including benign nevi and malignant melanoma.
    • Early and accurate diagnosis is crucial for appropriate management and patient outcomes.

    Observation:

    • Three patients presented with asymptomatic longitudinal pigmented bands on their fingernails.
    • Clinical suspicion of a junctional melanocytic nevus in the nail matrix was noted.

    Findings:

    • Histological examination confirmed the presence of junctional melanocytic naevus in the nail matrix for all three patients.
    • The study reviewed differential diagnoses and management strategies for nail pigmentation.

    Implications:

    Related Experiment Videos

  • This case series highlights the importance of considering benign nail matrix nevi in the differential diagnosis of longitudinal pigmented bands.
  • Local excision is recommended as the primary treatment modality for confirmed junctional melanocytic naevi of the nail matrix.
