**Question:** True about intestinal lymphoma

A. Lymphomas are rare malignancies of the small intestine.
B. Intestinal lymphoma often presents with vague abdominal symptoms.
C. Diagnosis depends on endoscopic and histopathological examination.
D. Treatment options include surgery and radiation therapy.

**Correct Answer: C. Diagnosis depends on endoscopic and histopathological examination.**

**Core Concept:** Intestinal lymphoma is a type of malignancy originating from lymphoid cells, which can affect the small intestine. These tumors can present with nonspecific abdominal symptoms, making diagnosis challenging.

**Why the Correct Answer is Right:** The correct answer is chosen because the diagnosis of intestinal lymphoma primarily relies on endoscopic examination and histopathological analysis, which is essential to confirm the presence of malignant lymphoid cells within the intestinal tissue.

**Why Each Wrong Option is Incorrect:**

A. While lymphomas are indeed rare malignancies, intestinal lymphoma specifically is rarer, making this statement not entirely accurate.
B. Although intestinal lymphoma can present with vague abdominal symptoms, relying solely on symptomatology for diagnosis would be insufficient.
D. Treatment options for intestinal lymphoma involve a combination of surgery and radiation therapy, but the correct statement should focus on diagnosis, not treatment.

**Clinical Pearl:** Intestinal lymphoma can present with non-specific symptoms such as abdominal pain, diarrhea, and weight loss. These symptoms are common in several gastrointestinal disorders, making the diagnosis challenging. Hence, a comprehensive evaluation involving endoscopy, histopathological examination, and radiological investigations is essential to confirm the diagnosis and plan appropriate treatment.
