Curiously the incidence of one of the Borderline serous tumours and the Borderline Mucinous tumour was sin a relatively younger age (28 years).
One patient had a borderline serous tumour, and one patient had a borderline mucinous tumour. Those two patients with borderline results were included in the benign group.
CA 125 value was 191 U/mL for borderline serous tumour and 9 U/mL for borderline mucinous tumour. The statistical analysis did not indicate any statistically significant difference between the CA 125 levels of the patients with malignant and benign adnexal masses (p=0.105) (Table 4).
Classification of the adnexal masses Histopathology results n (%) Benign masses 45 (100) Serous cystadenoma 15 (33.3) Endometrioma 12 (26.6) Abcess 5 (11.1) Mature cystic teratoma 4 (8.8) Fibrothecoma 4 (8.8) Mucinous cystadenoma 2 (4.4) Leiomyoma 1 (2.2) Borderline serous tumour 1 (2.2) Borderline mucinous tumour 1 (2.2) Malignant masses 6 (100) Endometrioid adenocarcinoma 2 (33.3) Granulosa cell tumour 2 (33.3) Carcinosarcoma 1 (16.6) Leiomyosarcoma 1 (16.6) TABLE 3.

Two Mucinous tumours included one Mucinous Cystadenoma and one Borderline Mucinous tumour.
ER-ve and PR positivity was seen in 3 cases, i.e., 2 Serous Cystadenoma and one Borderline Mucinous tumour.
BORDERLINE MUCINOUS TUMOUR (FIGURE 2): 3 cases (6%) of borderline mucinous tumour were reported out of 50 cases in the present study.
It has also been suggested that it may be more difficult to diagnose borderline mucinous tumours compared to borderline serous tumours because of their larger average size.5,12
