AB BACKGROUND: Perforin (Pf), a pore-forming protein, is a cytolytic
protein of killer cells. Its deposition in lesioned skin has not been
studied. OBJECTIVE: The purpose of this study is to show Pf deposition
in the lesioned skin and Pf expression in the dermal infiltrates of
various inflammatory skin diseases. METHODS: Frozen specimens obtained
from 29 patients with 5 different diseases were immunohistochemically
stained. RESULTS: Granular deposition of Pf was found in the lesioned
skin in 2 out of 5 cases of viral vesicles and in 3 out of 7 cases of
erythema multiforme. In the cases with Pf deposition, the percentages of
Pf+ cells in the dermis were higher than in those without deposition.
CONCLUSION: Pf released from natural killer cells or cytotoxic T
lymphocytes may play a role in tissue damage.
