Pneumatosis cystoides intestinalis after cetuximab chemotherapy for squamous cell carcinoma of parotid gland.

Pneumatosis intestinalis, defined as gas in the bowel wall, is often first identified on abdominal radiographs or computed tomography (CT) scans.

Hepatic epithelioid hemangioendothelioma and the danger of misdiagnosis: report of a case.

Malignant hepatic epithelioid hemangioendothelioma (HEHE) is a rare malignant tumor of vascular origin.

Misdiagnosis is not a rare event, and the consequences of such an event are catastrophic.
