Mucinous tumours have a significantly worse prognosis than serous
papillary and endometrial cancers.7 The current study was planned to evaluate the frequency and histopathological features of ovarian tumours in the Rawalpindi-Islamabad region of Pakistan.
Digital indocyanine green videoangiography of central serous
Most frequent histological type was serous
carcinoma (SC) followed by mucinous carcinoma (MC), endometrioid carcinoma (EC), clear cell carcinoma (CC), malignant brenner tumor (MBT) and seromucinous carcinoma (SMC) (60.6% n=20, 15.2% n=5, 9.1% n=3, 9.1% n=3, 3% n=1, and 3% n=1 respectively).
Out of three serous
carcinomas, 2(3.6%) were PR positive.
NRAS mutation in codon 13 (G13D, p.Gly13Asp; nucleotide: c.38G>A) was found in one patient (8.3%), a woman with low-grade serous
Large/giant ovarian cysts are benign in most of the cases and histopathologically these cysts are either serous
or mucinous .
The lack of cytologic atypia and mitotic figures, two features commonly seen in serous
carcinoma, lowered the suspicion for carcinoma at the time of surgery.

Subtypes of endometrial cancer include the more common type I, endometrioid adenocarcinoma, and the rare type II, which encompasses clear-cell, carcinosarcomas, and endometrial serous
chorioretinopathy is a retinal disorder that has been linked to the systemic use of corticosteroids.
Morphologically common benign ovarian tumors include cysts (both follicular and luteal) followed by serous
cyst adenomas and mucinous cyst adenomas4.
