Abstract

Pilomatricoma is a common benign adnexal tumor differentiating toward elements of the hair matrix and shaft. It typically presents as a solitary, deep, dermal nodule. We describe a case of a pilomatricoma with the unusual feature of a thick-walled dermal bulla overlying the tumor. We describe a case of bullous pilomatricoma and discuss the potential etiology of the bullous feature of the lesion. This article includes a case report and a literature review. Bullous pilomatricoma has rarely been described. A common pathological feature in this type of pilomatricoma is the presence of dilated lymphatics. Bullous morphea associated with dermal lymphatic dilation has also been described. In both bullous pilomatricoma and morphea, it is possible that individual pathological features of the lesion lead to obstruction and congestion of the dermal lymphatics thereby inducing enough dilation and edema to form a dermal bulla.
