Unusual dermoscopic features of multiple pilomatricomas, including a rare bullous variant.

Abstract

Dear Editor, Pilomatricoma, or Malherbe's calcifying epithelioma, is a benign neoplasm derived from hair follicle matrix cells. It usually presents as a solitary, firm, slow-growing subcutaneous nodule. Multiple pilomatricomas occur in about 2% of cases and may be associated with syndromes like Gardner's syndrome, Turner syndrome, and myotonic dystrophy. The bullous variant is an exceptionally rare form that presents with an overlying blister due to lymphatic dilation. Fewer than 30 cases of bullous pilomatricoma have been reported, and even fewer cases have involved multiple lesions, making this report particularly noteworthy. [...].
