Pilomatrixoma is a rare tumor occurring in fewer than 1:1000 skin biopsies. Its presentation as a solitary parotid mass treated by wide excision is unusual, with only three previously reported cases in the world's literature.
毛发上皮瘤是一种罕见的肿瘤，在每1000例皮肤活检中出现的病例不到1例。它表现为通过广泛切除治疗的孤立性腮腺肿块，这种情况并不常见，世界文献中仅报道过3例。
