## TL;DR

This case report describes a rare instance of diffuse large B-cell lymphoma occurring in the abdominal wall subcutaneous tissue.

## Contribution

The novelty lies in presenting a rare case of DLBCL in the subcutaneous abdominal wall with detailed imaging and immunohistochemical findings.

## Key findings

- DLBCL was found in the subcutaneous abdominal wall, an uncommon location for this lymphoma subtype.
- Imaging and immunohistochemical analysis confirmed the diagnosis of subcutaneous abdominal wall lymphoma.
- This case highlights the importance of considering DLBCL in unusual anatomical locations during clinical evaluation.

## Abstract

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma (NHL) and represents the most frequent malignant lymphoma in adults. It typically occurs in sites such as the neck, axilla, and groin; however, lymphoma originating in the abdominal wall subcutaneous tissue is relatively rare. This case report aims to present the imaging findings and immunohistochemical results of a patient with subcutaneous lymphoma located in the abdominal wall. To our knowledge, this represents a relatively rare case.
