Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Summary

Becker's nevus, a common skin condition, typically appears as a unilateral patch in adult men. This report details a rare case of Becker's nevus presenting segmentally on a teenage boy's face and oral mucosa.

Area of Science:

  • Dermatology
  • Clinical Case Reports
  • Medical Genetics

Background:

  • Becker's nevus (BN) is a common, benign melanotic epidermal hypermelanosis.
  • Typically presents as unilateral hyperpigmentation and hypertrichosis on the trunk of adult males.
  • Variations in presentation, including bilateral or multiple lesions and atypical locations, are documented.

Observation:

  • A 16-year-old male presented with two distinct Becker's nevi.
  • Lesions were located on the left side of the face in a segmental distribution.
  • Extension of the nevus onto the oral mucosa was noted.

Findings:

  • The case demonstrates a rare segmental facial presentation of Becker's nevus.
  • The involvement of oral mucosa represents an unusual feature.

  • This presentation deviates from the typical adult male trunk distribution.

    • Implications:

    • Highlights the diverse clinical spectrum of Becker's nevus.
    • Suggests the importance of considering atypical presentations in pediatric dermatology.
    • Contributes to the understanding of rare dermatological conditions and their management.
