An Unusual Presentation of Pilomatrixoma

The document discussed an unusual presentation of pilomatrixoma, a benign skin neoplasm originating from hair matrix cells, in an 18-year-old male with a painless lump on his left cheek. The lump was initially diagnosed as a sebaceous cyst but was later identified as pilomatrixoma after excisional biopsy. Pilomatrixomas were noted to be common superficial masses in the head and neck, particularly in children, with a low recurrence rate following surgical excision. The study highlighted the importance of considering pilomatrixoma in differential diagnoses for head and neck masses and emphasized the effectiveness of simple surgical excision as a treatment.
