Laparoscopic treatment of ovarian tumors in children: an experience of seven cases in Mansoura University Hospital

Table 1 Age of patients, tumor characteristics, type of surgery, and results of histopathology and tumor markers estimation

Case	Age (year)	Site	Torsion	Features and maximum diameter of the mass (cm)	Surgery	Pathology (all benign)	Tumor markers^c
1	10	Right ovary	No	Cystic 10	Unilateral salpingo-oophorectomy	Serous cystadenoma	Normal
2	11	Right ovary	Yes	Solid 6	Unilateral salpingo-oophorectomy	Necrotic unidentified	Normal
3	11	Right ovary	No	Cystic 10	Unilateral salpingo-oophorectomy	Serous cystadenoma	Normal
4	10	Left ovary	No	Cystic with ^afeatures of dermoid 7	Unilateral ovarian cystectomy	Mature cystic teratoma	High CA19.9 (117 U/ml)
5	10	Right ovary	Yes	Cystic with ^afeatures of dermoid 6	Unilateral ovarian cystectomy	Mature cystic teratoma	High CA19.9 (88 U/ml)
6	7	Left ovary	No	^bCystic mass with small solid component 10	Unilateral ovarian cystectomy	^bCystadeno-fibroma	Normal
7	9	Left ovary	No	Cystic with ^afeatures of dermoid 7	Unilateral ovarian cystectomy	Mature cystic teratoma	High CA19.9 (97 U/ml)

^aFeatures of dermoid in US and in MRI: cystic mass with layered lines and dots, fat–fluid level, and acoustic shadowing
^bCystadeno-fibroma that contains both epithelial and fibrous stromal components. The diameter of small solid component is 6 mm
^cTumor markers: CA19.9, CA125, alpha-fetoprotein, and HCG. Normal values: CA19.9 < 39 U/ml, CA125 < 35 U/ml, alpha-fetoprotein <9.5 ng/ml, and HCG <5 mu/ml
