Many authors described a higher frequency of pancreatic intraepithelial neoplasia in patients with pancreatic ductal adenocarcinoma, but also reported that it may be present in patients with the following disorders of the pancreas: mucinous cystic neoplasms, neuroendocrine tumors, chronic pancreatitis, serous cystadenomas
, acinar cell tumors, and pseudopapillary tumors .
A rare case of collision tumour was reported in our study, which showed two components of serous cystadenoma
and mature cystic teratoma.
Microcystic serous cystadenoma
of the pancreas with subtotal cystic degeneration: another neoplastic mimic of pancreatic pseudocyst.
is also a benign tumour of the ovary, which is responsible for about 30% of all epithelial ovarian neoplasms.
Classification of the adnexal masses Histopathology results n (%) Benign masses 45 (100) Serous cystadenoma
0%) had benign masses in group A (specifically, five mucinous adenomas, four mature cystic teratomas, two serous cystadenomas
, and one paratubal cyst), seven women (35.
After the removal, 4(57%) patients were determined to have serous cystadenoma
Two hundred and forty two benign surface epithelial tumours were found in this study out of which serous cystadenoma
was the most common accounting for 47.
8] The most common epithelial tumors were serous cystadenoma
followed by mucinous cystadenoma and the most common germ cell tumor was benign cystic teratoma (43 cases), similar results reported by Yasmin et al.
Less commonly, patients were diagnosed with serous cystadenoma
(14%), endometrioma (8%), mucinous cystadenoma (7%), benign cyst (6%), tumor of low malignant potential (5%), and paratubal cyst (3%).
The biggest serous cystadenoma
removed laparoscopically was 17 cm.
