Background:
The most frequent type of non-Hodgkin lymphoma (NHL) is diffuse large B-cell lymphoma (DLBCL). Although lymph nodes are the most commonly affected organs compromising 70% of DLBCLs, only 5% of extranodal lymphomas represent skeletal muscle involvement. Specifically, abdominal wall muscle involvement is rare and there are only a few reported cases of DLBCL with this type of muscle involvement. Painful abdominal mass was the main presenting symptom in these reported cases.
Case:
We are reporting a relapsed DLBCL with abdominal wall muscle involvement in a 65-year-old male, presenting with a discomfort and heaviness sensation in the right iliac region with no associated pain.
Conclusion:
A rare case of DLBCL with recurrence in the abdominal wall muscles as painless masses was reported in this case report. To our knowledge, it is considered the fourth reported in the medical literature. It shows the importance of the diagnostic process that combines imaging with histological examination and immune stains for accurate diagnosis.

The first classification is based on the development of the disease, and it includes the following categories:
Disorders of the Skeletal Muscle
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
