Primary localized cutaneous nodular amyloidosis (PLCNA) is rare and clinically noncharacteristic, presenting mostly as plaque-like lesions. We report a case of a progressively larger erythematous plaque following a contusion of the skin on the right zygomatic area, which was strangely covered with recurrent scattered 2 mm whiteish blisters to the extent that it was misdiagnosed as a herpesvirus infection several times over a decade. Pathology and special staining diagnosed nodular amyloidosis with milia.
Keywords: local trauma; milia; plaque; primary localized cutaneous nodular amyloidosis.
