A 39-year-old woman presented with abdominal wall mass 9 years after she un
derwent laparoscopic cholecystectomy for symptomatic gallstones. After surg
ical resection, a pathologic examination identified an abscess cavity withi
n the abdominal wall that was surrounded by a wide, diffuse, poorly defined
wall of dense fibrous tissue. An examination did not show neoplastic tissu
e. The cavity was bile-stained and contained a 2.5-cm gallstone. This case
shows a complication of laparoscopic cholecystectomy. Gallstones spilled du
ring the extraction of the gallbladder through the abdominal wall incision
may lead to a reactive process that clinically and microscopically may rese
mble a fibro-proliferative disorder, including a neoplastic process. This c
omplication of laparoscopic cholecystectomy is rare. Pathologists must be a
ware of its occurrence because examination of the solid fibrous wall may le
ad to diagnoses of reactive or neoplastic fibro-proliferative processes.
