Abstract

Inflammatory pseudotumor (IPT) is an uncommon clinical condition characterized by proliferation of spindle cells, inflammatory cells, and small vessels. IPT has been reported in various anatomical sites, including the orbit, lung, liver, spleen, and so on. IPT of the lymph node is very rare. We recently experienced a 65-year-old woman diagnosed with IPT of the lymph node in the splenic hilar, or distal supra-pancreatic area, mimicking gastric submucosal tumor. The tumor was removed without event using the laparoscopic method. This lesion in the splenic hilum is extremely rare and has not been cited in the current literature. We describe such a rare case of IPT with a review of the literature.

Figure

• 

  Fig. 1 (A) Gastroscopic finding showed bulging mucosa in the greater curvature side of the gastric body. (B) Endoscopic ultrasound finding showed a hypoechoic lesion in the muscularis propria layer, 2.5×2.0 cm in diameter, in the greater curvature side of the gastric body.

• 

  Fig. 2 Abdominal CT finding. The black arrow indicates a well-defined exophytic mass, with early enhancing nature in the greater curvature side of the gastric body.

• 

  Fig. 3 Intraoperative finding. The white arrow indicates a well-defined mass in a location between the upper border of the distal pancreas and the splenic hilum.

• 

  Fig. 4 The lymph node in the specimen measured 3.3×3.0×2.2 cm and weighed 12.7 g.

• 

  Fig. 5 Histopathologic finding. (A) This histopathologic features were consistent with lymph node (H&E, ×10). (B) The lymph node showed plasma cell infiltration and sclerosis in the focal area. The inflammatory cells infiltrate, including plasma cells, lymphocytes, eosinophils, and sclerosis were also noted in the perinodal soft tissues (H&E, ×100).
