Abstract
-
Nonparasitic true splenic cyst is a rare disease and the epidermoid cyst accounts for the
majority of the cases. And the epidermoid cyst producing CA19-9 is extremely rare.
We present a case of true splenic cyst with high cystic fluid CA19-9 level. A 26-year-old woman
complained left upper quadrant abdominal pain. Abdominal ultrasonography and CT depicted a 17 x
13 cm sized cystic lesion in the left upper abdomen. The aspirated cystic fluid showed high
concentration of CA19-9, but serum CA19-9 level was normal. Spleen with huge unilocular cyst was
removed surgically. The cyst was lined with single layered cuboidal epithelial cells and negative for
immunohistochemical staining with anti-CA19-9 antibody.
