Abstract
Background
Mature cystic teratoma (MCT), usually known as dermoid cysts derived from primordial germ cells. Comparing with different other types of germ cell tumors like dysgerminomas, and endodermal sinus tumors, they are most commonly observed. The aim of this study was to evaluate the prevalence, clinical and pathological characteristics; and complications of MCT of the ovary in Chitwan district, central region of Nepal.
Methods
A retrospective, hospital based study was carried out in all histopathologically proven cases of MCT from July 2011 to June 2014. Relevant data were retrieved from the records of Pathology Department of Chitwan Medical College-Teaching Hospital. According to the guidelines of World Health Organization (WHO), classification of ovarian tumors was done mainly based on histogenetic principles.
Results
Seventy four MCTs were studied from 62 patients. Majority of the patients (74.19%) were in reproductive age group of 21-40years. Chief complaint was abdominal pain. Ascites was the most common complication found in 6.45% patients. The rate of torsion was 4.84%; larger tumors underwent torsion more frequently than smaller tumors (P <0.05). Right-sided tumors outnumbered the left-sided tumors. The bilaterality rate was 19.35%.
Conclusion
Integrated MCT accounts for 49% of all ovarian neoplasm and occur principally during the reproductive years. Postmenopausal women or children sometimes affected. Prevalence rates of torsion were relatively less. Larger tumors have more risk of undergoing torsion than smaller tumors.
