Abstract
Hormone replacement therapy (HRT) containing estrogens is generally used to relieve climacteric symptoms and to prevent osteoporosis and coronary heart disease [
1], however, there has been increasing evidence of the HRT as the risk of hormone-dependent neoplasms including breast cancer [
2], uterine endometrial cancer [
3], ovarian cancer [
4], and even lung cancer [
5]. Noteworthy is mucinous cyst neoplasms (MCNs) of the pancreas, characterized by mucin-producing columnar epithelium supported by “ovarian-like” mesenchymal stroma, occur mostly in females expressing estrogen receptors [
6,
7]. Although several reports regarding the closed relationship between MCNs and pregnancy [
8,
9] might imply potential sex hormone-dependency of the MCNs [
10], no correlation has been reported. This is the first case report of malignant MCN developing during continuous HRT after hysterectomy.
