Pediatric ovarian tumors in a tertiary care hospital of Kolkata: An experience of last 5 years with its clinicopathological correlation

Background: Pediatric ovarian tumors are rare with an approximate incidence of 2.6 per 100,000 girls per year. Aims and Objectives: This study was done to delineate the clinicopathological profile of pediatric ovarian masses encountered in a tertiary care hospital over 5 years. Materials and Methods: A retrospective study was conducted for a period of 5 years during which all patients whose age did not exceed 20 years and underwent surgical resection of ovarian masses, were included. History, operative notes, gross findings, and microscopic features of each case were noted. Results: A total of 76 cases were included in the study. The age of patients ranged between 2 and 20 years with a mean of 17 ± 2.5 years. Of the 76 cases, 53 (69.7%) were benign and 23 (30.3%) malignant tumors. The benign tumors included 16 cases each of teratoma (21.1%) and serous cystadenoma (21.1%), and 21 cases of mucinous cystadenoma (27.6%). Germ cell tumors were the commonest malignant tumors in patients up to 15 years of age and they included four cases of dysgerminoma (5.3%) and one case of immature teratoma (1.3%). Between 16 and 20 years, 8 cases of serous cystadenocarcinoma were found (10.5%), in addition to seven malignant germ cell tumors (9.2%). One case (1.3%) each of granulosa cell tumor and sertoli leydig cell tumor was also found in the same age group. Conclusion: Pediatric ovarian tumors require early attention and institution of appropriate treatment since they bear important implications on the future lives of young females.
