## TL;DR

Tick bites can cause identical skin reactions resembling lymphoma, with specific visual clues even when ticks are not visible.

## Contribution

Demonstrates a consistent immune response pattern in cutaneous pseudolymphoma caused by tick bites.

## Key findings

- Tick bites at two sites showed identical clinicopathological features.
- Dermoscopic clues like retained cement cones and white reticular lines were observed.
- The immune response was stereotypical within a single individual.

## 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.
