Background: Breast cancer is the second most common cancer in women next only to cervical cancer. Multiple factors are associated with an increased risk of developing breast cancer. For the early detection of carcinoma of breast, a number of biochemical markers have been studied to evaluate the malignancy. Aim: To analyse serum Lactate Dehydrogenase, Gamma Glutamyl Transpeptidase, liver enzymes (SGOT, SGPT, & ALP) and total proteins in diagnosis of carcinoma breast patients and compared with controls. And evaluate the relationship of serum LDH, GGT levels with ALP of carcinoma breast patients of post-menopausal age group. Material & Methods:The serum biochemical markers were estimated in 60(30-premenopausal women, 30-post menopausal women) clinically and histopathological confirmed patients with carcinoma breast and 40 number of healthy age-matched individuals served as control. Lactate dehydrogenase (LDH) Serum Gamma Glutamyl Transpeptidase (GGT), were analysed and estimated. Statistics: Data was analysed with student's paired 't'-test was determined. Results: The mean serum LDH, GGT, and ALP activities in patients with carcinoma breast were significantly (p<0.0001) increased as compared to controls, and a steady increase was observed in their levels from premenopausal to post-menopausal women. Conclusion: In this study, it is to suggest that the estimation of LDH, GGT, and ALP can be used as routine screening tests in all suspected carcinoma breast patients and for general population and can detect metastasis.

Background Mucinous cystic neoplasm of the liver (MCN-L) is a rare cystic tumor as defined by the 2010 World Health Organization classification. MCN-L usually does not communicate with or grow into the bile duct. Herein, we present a rare case of MCN-L with a polypoid nodule protruding into the bile duct. Case presentation A 69-year-old woman was referred to our hospital for elevated serum liver enzyme levels and obstructive jaundice. The patient also complained of abdominal pain in the right hypochondriac region. Abdominal ultrasonography showed a cystic lesion in segment 4 (S4) of the liver. Computed tomography revealed a 4-cm multilocular cystic lesion with a thick wall and multiple septal formations, showing a cyst-in-cyst appearance in S4. Endoscopic retrograde cholangiography showed a contrast defect between the left hepatic duct and the common bile duct, which was suspected to be a nodular lesion in the bile duct. Bile cytology and biopsy of the nodular lesion showed no malignant findings. Based on these findings, the differential diagnosis in this patient included intraductal papillary neoplasm of the bile duct and MCN-L, which had malignant potential. The patient underwent left hemihepatectomy, including caudate lobe excision with bile duct resection and right hepatocholangiojejunostomy. Macroscopic findings showed a 40 × 29 mm multilocular cystic lesion with a polypoid nodule that protruded into the left intrahepatic bile duct. As an ovarian-like stroma was observed in both cystic and polypoid lesions microscopically, the histopathological diagnosis was MCN-L. The postoperative course was uneventful, and the patient was discharged 24 days after surgery. The patient is currently alive without recurrence 22 months after the surgery. Conclusion Although MCN-L rarely communicates with the bile duct, it is necessary to consider that MCN-L could grow into the bile duct, occasionally causing obstructive jaundice.
