PRIMARY CARCINOMA OF THE DUODENUM

Carcinoma of the duodenum.

We report two patients with primary adenocarcinoma of the duodenum who underwent successful pancreatico-duodenectomy (modified Whipple operation). One patient died from an unrelated cause three years following surgery whilst the other remains well and clinically free of disease 3 years after resection. An aggressive surgical policy in patients with this rare tumour seems justified.

Carcinoma of the duodenum.

Ewing (1931) states that the incidence of malignant tumours of the small intestine is 3% of neoplasms of the gastrointestinal tract. Shallow, Eger, and Carty (1944) reported the incidence of primary carcinoma of the duodenum in a study of 350,286 necropsies as 003%; the duodenum is affected in 45.6% of cases of small intestinal neoplasms. In this series care was taken to exclude undifferentiate...

Primary Intraosseous Carcinoma of the Maxilla

A primary intraosseous carcinoma (PIOC) is a squamous cell carcinoma arising within the  jawbone andshould be differentiated from a malignant ameloblastoma.  It  is not due to arising from an odontogenic cyst or tumor. The possibility of the lesion being  a metastasis fromanotherprimary site should be considered, and excluded by a careful history and examination. The diagnosis of a PIOC is ra...

Sarcomatoid carcinoma of the duodenum.

Primary tumours of the duodenum.

Six primary duodenal tumours were diagnosed in our 300 bed institute during a period of 10 years. Two patients had benign tumours (leiomyoma and carcinoid) and four had malignant tumours (adenocarcinoma). The most common manifestation was severe iron deficiency anemia. Diagnosis was usually delayed (with a mean time of 7.7 months from initial complaints), endoscopy being the most common and use...
