Adenosquamous carcinoma presenting as liver abscess.

Adenosquamous carcinoma (ASC) has a nonspecific presentation. We report a patient with ASC who presented with fever and epigastric pain. Computed tomographic findings and clinical features were suggestive of a liver abscess, while ultrasonography showed a complex space-occupying lesion. Biopsy revealed a lesion with malignant glandular and squamous components, a finding that was compatible with ASC. Complex space-occupying lesions should raise the suspicion of a mass lesion. Subtle imaging clues of a metastatic disease were reviewed retrospectively.
