Latent Gallbladder Carcinoma in a Young Adult Patient with Acute Cholecystitis: Report of a Case

Abstract

Acute cholecystitis associated with gallbladder carcinoma is very rare in young patients (younger than 30 years of age). Moreover, a definitive preoperative diagnosis is difficult. A 26-year-old man was referred to our hospital with a 5-day history of right upper quadrant pain. Computed tomography and ultrasonography demonstrated an enlarged gallbladder with a diffuse thick wall and a 2-cm gallstone obstructing the cystic duct. Magnetic resonance cholangiopancreatography showed no evidence of an anomalous pancreaticobiliary junction. The patient showed an elevation in the white blood cell count, serum C-reactive protein, and alkaline phosphate; however, total bilirubin, alanine aminotransferase, and tumor markers including carcinoembryonic antigen and carbohydrate antigen 19-9 were all within the normal ranges. The preoperative diagnosis of gallstone-induced acute cholecystitis was made and an open cholecystectomy was thus performed 2 days after admission. The macroscopic findings showed a necrotic enlarged gallbladder with a thick wall and a gallstone, but no intraluminal nodular lesion. Histologic examinations revealed well-differentiated focal adenocarcinoma in the gallbladder mucosa, but no venous, lymphatic, or perineural invasion. The postoperative course has been uneventful with no recurrence 18 months postoperatively.

Diagnosis and management of gallbladder cancer

“…For elderly patients, especially women, presenting with acute cholecystitis and abnormal liver function, CT demonstration of focal gallbladder wall thickening, intraluminal masses, small gallbladder with diffuse wall thickening, and enlarged regional lymph nodes are suggestive of concurrent GBC.

A nomogram for predicting cancer-specific survival for elderly patients with gallbladder cancer

“…In recent years, the incidence of GBC is increasing in many countries and regions around the world, especially in Asia [4][5][6][7]. Furthermore, elderly GBC patients have a higher incidence, higher morbidity, and shorter overall survival [8,9]. Gallbladder cancer patients are mainly middle-aged and elderly people.…”
