Unusual malignant neoplasms of ovary in children: two cases report.

Sex cord tumors with annular tubules are known to originate from the sex cord of embryonic gonads that synthesize Sertoli cells, Leydig cells, granulosa cells, and theca cells of the ovarian stroma, while ovarian small cell carcinoma of the hypercalcemic type is a type of neuroendocrine tumor. Both these tumors are uncommon, potentially malignant neoplasms in children. We report the case of a sex cord tumor with annular tubules in an 11-year-old girl and a case of small cell carcinoma of the hypercalcemic type in a 10-year-old girl.

Background: Para-umbilical block was an old block that regains a new interest. No study was available using Ropivacaine in this block.

Aim: To compare quality of analgesia after using Ropivacaine 0.
