Abstract

Hepatoid adenocarcinoma of the stomach (HAS), a rare and unique histological subtype of gastric cancer, accounts for less than 1.5% of all gastric cancers. Historically, this subtype is found to have a poor prognosis in comparison to other types of gastric cancer. While the diagnosis is made based on pathological findings, most cases described in the literature are associated with elevated alpha-fetoprotein (AFP) levels. We present a case of AFP-negative HAS with additional unique pathologic findings of signet ring cells which has been reported only once in the literature. Given the rare and late presentation of the disease, AFP-negative HAS should be included in the differential diagnosis in patients with suspicion for gastric cancer.
