49) Erdogan, et al hypothesized that epithelial cells covering the embryonic gonads in early fetal life might be the common origin for
cystadenoma and ovarian stroma.
Of the benign neoplasms, serous
cystadenomas was the most common neoplasm, 40 cases (43%).
Because a mucinous
cystadenoma or cystadenocarcinoma was a possibility, we deferred a biopsy.
Other terms for this lesion include oncocytic
cystadenoma, oncocytic adenomatous hyperplasia, cystic oncocytic metaplasia, and eosinophilic granular cell cyst.
Tumor-totumor metastasis: report of two cases of renal cell carcinoma metastasizing to microcystic serous
cystadenoma of the pancreas.
Papillary
cystadenoma is a rare benign neoplasm of the epididymis.
3-6) To the best of our knowledge, retroperitoneal
cystadenoma during pregnancy has not been reported.
The differential diagnosis based on imaging findings included cystic mesothelioma and retroperitoneal
cystadenoma.
The pathology most consistent with cysts of the large-volume category and thus requiring surgery is serous
cystadenoma.
She was found to have a microperforation of the sigmoid colon and multiple gynecologic pathologies, including myomata, right serous
cystadenoma, and left tubo-ovarian complex suggestive of endometriosis.
Macroscopic as well as microscopic pathological features, including the presence of cell atypia, established the diagnosis of low-grade mucinous
cystadenoma arising in a completely isolated and infected ileal duplication cyst.
