Cutaneous Pseudolymphomas With Identical Clinicopathological Features Induced by Tick Bites at Two Separate Sites

Abstract

Identical dermoscopic and histopathologic findings at two distinct tick bite sites demonstrate a stereotypical immune response within a single individual of cutaneous pseudolymphoma, with diagnostic clues including retained cement cones and white reticular lines, even in the absence of visible tick parts.
