Pleural effusion, ascites, colon ulcers and hematochezia: What we can learn from the diagnostic process of a patient with plasma cell myeloma: A case report

Figure 1 Computed tomography images. A: Pneumonia; B and C: Pleural effusion; D: Ascites.

Figure 2 Colonoscopy images. A and B: Local ulcer formation with intestinal lumen stenosis at 60 cm (A) and 55 cm (B) from the anus; C: Local mucosal edema with ulcer formation in the descending colon; D-F: Local mucosal congestion and edema with erosion in the sigmoid colon (D and E) and rectum (F).
