Invasive Papillary Adenocarcinoma of Gallbladder: A Case Report.

Papillary gallbladder adenocarcinoma (PGA) represents 5.0% of all malignant tumor of gallbladder. An early diagnosis is essential as this malignancy progresses silently with a late diagnosis, often proving fatal. A 63 year old female presented with right upper quadrant pain, palpable gallbladder on clinical examination and hypoechoic shadow suggestive of gall stone inside on ultrasound. But during an attempt to open cholecystectomy surgeons found tiny papillary growth involving whole fundus and part of the body on June 2020 at an outside hospital, Khulna, Bangladesh. Radical cholecystectomy was done by the surgeon with enlarged portal lymph node dissection and a small portion of hepatic resection. Histopathology demonstrated a well-differentiated invasive papillary adenocarcinoma with muscle invasion. There was no metastasis in the liver and lymph nodes show reactive hyperplasia.
