Subcutaneous Splenosis Presenting 37 years post-traumatic splenectomy; A Case Report

Area of Science:

• Surgical Pathology
• Abdominal Imaging
• Transplantation Biology

Background:

• Splenosis is autotransplantation of splenic tissue in ectopic sites after splenectomy.
• It can occur in various locations like the liver, thorax, pelvis, and subcutaneous tissues.
• While often asymptomatic, it may cause localized symptoms such as abdominal pain.

Purpose of the Study:

• To report an extremely rare case of subcutaneous splenosis.
• To discuss its presentation and diagnostic considerations.
• To highlight the long-term implications following traumatic splenectomy.

Main Methods:

• A case presentation of a 40-year-old female with a history of splenectomy at age three.
• Clinical examination revealed a stable, non-painful right upper quadrant mass.
• SPECT scan confirmed extraperitoneal splenosis; laboratory results were within normal limits.

Main Results:

• Subcutaneous splenosis was diagnosed 37 years after a traumatic splenectomy.
• The condition presented as a stable, asymptomatic soft mass.
• Diagnostic imaging confirmed ectopic splenic tissue in the right upper quadrant.

Conclusions:

• Splenosis is an acquired condition resulting from splenic tissue auto-transplantation.
• Subcutaneous splenosis is exceptionally rare, typically associated with surgical scars post-splenectomy.
• Delayed presentation is possible, and surgical intervention depends on mass location and patient preference.
