Abstract

The patient is a 10-year-old male who presented to a dermatologist regarding a bleeding plaque on the right scalp. The initial pathology report demonstrated an atypical endophytic squamous proliferation with an infiltrative pattern, raising concern for squamous cell carcinoma versus pseudoepitheliomatous hyperplasia. Physical exam showed a painless 4.4 x 1.2 cm elliptical, rough, orange-to-pink plaque with waxy superficial scale on the left forehead. Wide local excision was performed, and pathology confirmed no residual carcinoma. Squamous cell carcinoma arising in a nevus sebaceous in a pediatric patient is exceedingly rare, but as demonstrated by this case, does occur, emphasizing the need for improved guidelines for management to optimize treatment in the pediatric population.
