A large intraabdominal pleomorphic lipoma caused significant weight gain and mobility issues in a 65-year-old man. Surgical removal of the 19.5 kg tumor led to a full recovery, with the patient remaining well four years post-operation.

Area of Science:

Surgical Oncology
Gastroenterology
Pathology

Background:

Pleomorphic lipomas are rare, benign tumors typically found in the subcutaneous tissue.
Intraabdominal lipomas are uncommon, and massive ones present unique diagnostic and surgical challenges.

Observation:

A 65-year-old male presented with a rapidly growing abdominal mass, leading to 25 kg weight gain, leg edema, and impaired ambulation.
Initial assessment suggested an inoperable condition due to the mass's size and location.

Findings:

Surgical exploration revealed a 19.5 kg (43 lbs), 50 cm intraabdominal pleomorphic lipoma.
Complete surgical resection of the massive tumor was achieved.

Implications:

This case highlights the possibility of successful surgical intervention for extremely large intraabdominal lipomas previously deemed inoperable.
