Subcutaneous abdominal wall involvement in diffuse large B-cell lymphoma: case report

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.
