Abstract: Involvement of the abdominal wall by lymphoma is rare and often misdiagnosed because of its nonspecific clinical presentation. We report the case of an 80-year-old woman who presented with a rapidly enlarging subcutaneous abdominal mass, initially presumed to be a soft tissue abscess. Imaging was inconclusive, and a surgical biopsy was performed. Histopathological and immunohistochemical studies revealed Diffuse large B-cell lymphoma (DLBCL). Despite the diagnosis, the patient experienced a rapid clinical decline, precluding systemic therapy. Given the rarity of abdominal wall involvement in non-Hodgkin lymphoma and its potential for misdiagnosis, this case reinforces the need for heightened clinical suspicion and timely intervention in atypical soft tissue masses.
