Ovarian mucinous cystadenoma with extended calcification in an 11-year-old girl: case report and review of the literature.

Abstract

The majority of ovarian masses in childhood and adolescence are non-epithelial in origin, with a predominance of germ cell tumors, while epithelial neoplasms comprise a small proportion of the total (approximately 15-20%). Mucinous cystadenomas in particular are only sporadically reported in this age group. We present a case of an ovarian mucinous cystadenoma with extended calcification in a premenarchal 11-year-old girl. Pediatric mucinous cystadenomas of the ovary may on rare occasions display extended calcification. Careful evaluation of the remaining pathological features of the tumor is needed in order to avoid misinterpreting this relatively non-specific finding as a feature of malignancy.
