Duodenal diverticulum: case report of a perforated extraluminal diverticulum containing ectopic pancreatic tissue.

Ectopic pancreatic tissue within a duodenal diverticulum has not been previously described in the English-language literature, to our knowledge. We report a case of a 52-year-old woman who presented with a perforated duodenal diverticulum after upper endoscopy. Operative resection and repair of the perforated diverticulum was performed, and, on microscopic examination, ectopic pancreatic tissue was found within the diverticulum.

Stereotactic core needle biopsy of nonpalpable breast lesions: initial experience with a promising technique.

Objectives: To evaluate the correlation between the pathological findings of stereotactic core needle biopsy (SCNB) and the prebiopsy mammographic findings, as well as the pathological findings of lesions that were subsequently removed by surgical excision.

Design: A retrospective review of 97 consecutive patients who underwent 100 SCNBs of suspicious nonpalpable mammographic lesions. The criterion standard is surgical excisional biopsy with needle localization.

Sutureless intraluminal graft for repair of abdominal aortic aneurysm.

A series of seven patients undergoing elective repair of abdominal aortic aneurysms using sutureless intraluminal aortic prostheses for infrarenal tube grafts was reviewed. Follow-up was five to seven months. There was no morbidity related to the graft and one late mortality.

In situ lobular carcinoma of the breast.

Nineteen patients who did not have mastectomy for in situ lobular carcinoma that was diagnosed by excisional biopsy were followed up for a period of seven to 21 years. In two patients, infiltrating carcinoma developed; each had mastectomies. They were followed up for 20 and 21 years.
