Inflammatory pseudotumor of the spleen

Area of Science:

• Pathology
• Oncology
• Radiology

Background:

• Splenic masses can present diagnostic challenges, necessitating accurate characterization.
• Inflammatory pseudotumors are uncommon lesions with diverse presentations across organs.

Observation:

• Two cases of splenic inflammatory pseudotumor are presented.
• One pseudotumor was detected via CT scan prior to splenectomy; the other was an incidental finding during pathology.
• Gross examination revealed alarming lesions, necessitating further investigation.

Findings:

• Microscopic analysis confirmed the splenic lesions were unequivocally inflammatory and benign.
• This entity has not been previously described in the spleen.

Implications:

• Highlights the importance of microscopic examination for diagnosing splenic lesions.
• Adds to the differential diagnosis of splenic masses, particularly concerning benign inflammatory conditions.
• Suggests further research into the etiology and specific diagnostic criteria for splenic inflammatory pseudotumors.
