# Cutaneous miliary Lymphocytoma: A Case Report with Immunohistochemical Findings

## TL;DR

This case report describes a rare skin condition that looks like lymphoma but is benign, confirmed through lab tests and successfully treated with corticosteroids.

## Contribution

The paper presents a new case of miliarial type pseudolymphoma with detailed immunohistochemical confirmation and treatment response.

## Key findings

- The patient had multiple micropapules on her face, consistent with miliarial type pseudolymphoma.
- Immunohistochemistry confirmed a polyclonal lymphoid infiltrate, ruling out lymphoma.
- Topical corticosteroids effectively treated the condition.

## Abstract

Cutaneous pseudolymphomas (PSLs) as lymphocytic infiltrates are benign lesions that clinically and histopathologically mimic lymphomas. Miliarial type lymphocytoma cutis is an uncommon type of pseudolymphoma that is characterized by multiple semi-translucent micropapules on the sun-exposed regions. We present a 61-year-old woman who was admitted to our clinic with diffuse, sand-like, and erythematous micropapules on her face. Microscopic findings revealed nodular lymphoid aggregation, with the germinal center formation consisting of polyclonal lymphoid infiltrate confirmed by Immunohistochemistry (IHC) studies. According to this clinicopathological correlation, the miliarial type pseudolymphoma was confirmed and she was treated with topical corticosteroid ointment with a good response.
