Unusual Cases: Rare Red Tumor and Extra Breast with Wart-like Tumor
A 16-year-old girl developed a rare type of pilomatricoma, a benign tumor that typically grows on the head or neck, on her shoulder. The tumor, known as a "bullous pilomatricoma," appeared as a red lump and grew to cover an area of about 5.5 square inches. It oozed a jellylike substance when punctured. The cause of this type of tumor is unknown, but two theories suggest that lymph buildup or the release of enzymes near the tumor may contribute to its bulbous appearance. The tumor was surgically removed, and there has been no recurrence after one year of follow-up.
