Abstract
- Pilomatricoma is a benign adnexal tumor differentiating toward elements of the hair matrix and shaft. It typically presents as a solitary, deep, dermal nodule, but other variants, such as anetodermic form and pseudo-bullous form have rarely been reported. A 22-year-old man presented with erythematous 4X5cm sized bulla-like nodule of about 1 month history on the upper back. Histopathologic examination of the lesion showed a well-circumscribed dermal nodule composed of basophilic cells, shadow cells, and transitional cells. There were also marked lymphangiectatic dilatations above the tumor in the upper dermis. We diagnosed this case as a lymphangiectatic pilomatricoma with pseudo-bullous appearance.
