Answer

Answer

The malignant potential of this lesion has been estimated to be 10-50%. Degeneration into basal cell carcinoma is most common; however, other malignancies include adnexal tumors and squamous cell carcinoma. The color tends to be yellowish orange. The lesion is slightly raised, with a waxy appearance. When located on the scalp, it is devoid of hair. An accelerated growth phase may be observed during adolescence secondary to changes in the hormonal milieu.
