Uncommon and Unexpected Gallbladder Lesions

Uncommon and Unexpected Gallbladder Lesions

Gallbladder carcinoma is a rare malignancy, usually seen in the sixth to seventh decade of life, with a strong female predominance. The prevalence varies in different parts of the world. In India, the Indian Council of Medical Research has found an incidence of 4.5/lakh population in males, and 10.1/lakh population in females in North India and 1.2/lakh population in South India respectively. Carcinoma often presents with signs and symptoms of cholecystitis and may not be suspected clinically and sometimes even in gross examination. Hence, it is essential that all gallbladders that are removed are thoroughly sampled. Associated cholelithiasis may be seen in 80% of cases. We had one case which presented as cholecystitis, and malignancy was not suspected clinically. These tumours are located in the body or fundus in 90% of the cases. On gross appearance they may be seen as nodular or polypoid masses, as a thickening of the wall or as a diffusely infiltrating tumour.
