Abstract
- Pilomatricoma or calcifying epithelioma of Malherbe is a benign tumor originating from the matrix of hair follicles. Clinically, these tumors are classified as familial, perforating, multinodular, exophytic, anetodermic, bullous, and giant pilomatricomas. The bullous variety is observed only in 3 to 6% of cases. Furthermore, multiple pilomatricomas are rare and are usually associated with genetic disorders. To date, only 13 cases of bullous pilomatricoma and 8 cases of multiple pilomatricomas have been reported in Korean dermatologic literature. Among these cases, no case of multiple bullous pilomatricomas has been reported. This report describes a 23-year-old healthy man who was diagnosed with multiple pilomatricomas with bullous features, based on clinical and histopathological findings.
