title: Long-term survival of a patient with advanced adenosquamous carcinoma of the gallbladder after radical resection.
abstract: Patients with adenosquamous carcinoma of the gallbladder tend to present with a bulky tumor that frequently displays involvement with adjacent organs, and diagnosis is usually made at an advanced stage. This may contribute to the poor prognosis of patients with adenosquamous carcinoma of the gallbladder compared to patients with adenocarcinoma. We present herein a patient with advanced adenosquamous carcinoma of the gallbladder who is doing well with no evidence of recurrence more than 5 years after radical resection. A 72-year-old woman complaining of generalized fatigue and loss of appetite was referred to our hospital with suspected cholelithiasis, following ultrasonography done at another hospital. On admission, abdominal ultrasonography and computed tomography revealed an irregularly shaped solid mass extending from the fundus of the gallbladder, and invasion of the stomach was strongly suspected. Gallbladder carcinoma was diagnosed, and radical resection, including partial gastrectomy, was performed. Histopathologically, adenosquamous carcinoma was diagnosed, and it was graded as si, hinf0, binf0, pv0, a0, t4, n0, and stage IVa.
