Pathological Features of Ovarian Tumors, Diagnosed at a Tertiary Care Hospital in Afghanistan: A Cross-sectional Study

In Afghanistan, research work is still in its infancy and there is no national level tumor registry at the moment in the country that could elaborate the histopathological features of ovarian tumors in the country. The current study was conducted with the aim to describe pathological characteristics of ovarian tumors diagnosed at tertiary level in Afghanistan.A descriptive cross-sectional study was conducted, including 198 cases diagnosed with ovarian tumors, that were consecutively included in the study from July 2017 to August 2020. All the cases were diagnosed at the Department of Pathology, French Medical Institute for Mothers and Children, Kabul, Afghanistan, that receives biopsy samples from all of the tertiary care institutions in Kabul.In the current study, majority of the ovarian tumors were benign and presented with nonspecific symptoms. The mean age at diagnosis was 34.4 (SD ±13.4). Benign tumors comprised 81.8%, borderline 1.5% and malignant 16.7% of the cases. Majority of the diagnosed tumors were from surface epithelium in origin, followed by germ cell tumors, sex cord stromal tumors, and a single metastatic tumor. The most common benign neoplasm was mature cystic teratoma, followed by benign serous cystadenoma. Considering the malignant tumors, serous cystadenocarcinoma and adult granulosa cell tumors were predominant, followed by endometrioid adenocarcinoma and mucinous cystadenocarcinoma. More than half of the ovarian tumors occurred between 21 and 40 years of age.In the current study, the proportion of malignant ovarian neoplasms was significantly less than benign lesions. Although, many of the pathological features related to ovarian neoplasms were similar to the features demonstrated in other regions of the world, there were important findings that were exclusively noted in the cases diagnosed in Afghanistan.
