[ABSTRACT]
Enteropathy-Associated T Cell Lymphoma (EATL) is a rare malignancy with
annual incidence of 0.5–1 per million people and typically manifests
with symptoms like chronic diarrhea, weight loss, and malabsorption (1).
In this case report, we describe an unusual presentation of EATL in a
49-year-old otherwise healthy gentleman who presented with sudden-onset
severe abdominal pain and vomiting. Despite the absence of classical
symptoms, clinical examination revealed signs of peritonitis, prompting
further investigations. Chest X-ray confirmed the presence of free gas
under the diaphragm, leading to the necessity of an emergency
laparotomy. Intraoperatively, a mobile mass was discovered, and surgical
intervention was performed. Histopathological examination confirmed T
cell lymphoma, emphasizing the importance of considering rare
malignancies in the differential diagnosis of acute abdominal pain.
