Fibroepithelioma of Pinkus
FEP, like BCC, is seen with increasing frequency in individuals older than 50 years. While FEP is thought to be a variant of BCC, the tumor displays some unique characteristics. Unlike BCC, FEP is more common in females than in males. It is also seen on the lower back on non-sun-exposed skin, suggesting that UV light may have less of a role in its pathogenesis. Some have suggested that FEP would be best classified as a benign counterpart of BCC, such as a trichoblastoma.
Pediatric Patient Considerations:
BCC are extremely uncommon in children without predisposing conditions. However, FEP has been described in an otherwise healthy child as young as 3 years.
