Splenosis is the autotransplantation of splenic tissue following surgery or trauma. While it has been reported to cause a number of complications, splenosis is most commonly an incidental finding at laparotomy or on imaging studies. In our study, a case of massive, acute gastrointestinal hemorrhage occurred secondary to splenosis involving the small bowel. While there are several reports of self-limited gastrointestinal hemorrhage secondary to splenosis involving the gastric fundus, we are aware of no reports of massive, acute intestinal bleeding caused by this condition. Splenosis should be considered in the differential diagnosis of gastrointestinal hemorrhage in patients who have experienced prior splenic trauma or splenectomy.

An unusual case of multiple myeloma is presented in which recurrence of the disease after a four-year remission was heralded by an infiltrating plasmacytoma of the breast. The clinical and histologic features of this neoplasm are presented and compared with ten previously reported cases of plasmacytoma of the breast.

Long-term insulin secretion was investigated in seven biohybrid capillary devices seeded with canine islets. Approximately 50,000 islets could be isolated from a single canine pancreas using collagenase digestion in conjunction with the recently described Velcro technique. Devices were perfused with tissue culture medium 199 containing 300 mg/dl glucose. Insulin secretion fell during the first 1-2 days of culture from approximately 18 to 6 U/day. After 3-4 wk of perfusion, however, there was a gradual rise in insulin output that reached greater than 15 U/day after 7 wk. Insulin output eventually stabilized at 18-20 U/day. Two of these devices were studied for 80 and 86 days, respectively, and continued to secrete these same amounts of insulin. Glucose-induced insulin release was studied after 1 and 4 wk of culture and was well preserved.
