Molecular evaluation of PIK3CA gene mutation in breast cancer: determination of frequency, distribution pattern and its association with clinicopathological findings in Indian patients.

Somatic mutations in the PIK3CA gene are common in breast cancer and represent a clinically useful marker for prognosis and therapeutic target. Activating mutations in the PI3K p110 catalytic subunit (PIK3CA) have been identified in 18-40 % of breast carcinomas. In this study, we evaluated PIK3CA mutation in 185 Indian breast cancer patients by direct DNA sequencing.

Adrenocortical carcinoma presenting as a rupture and extensive retroperitoneal haemorrhage.

Adrenocortical carcinoma (ACC) is an extremely rare tumour. We are reporting a 45-year-male patient who had a history of sudden severe worsening epigastric pain and fullness in abdomen, with giddiness. The radiological investigations showed a large right suprarenal mass with extensive destruction and retroperitoneal haemorrhage, with extra capsular, periportal and liver metastases.
