Gastrointestinal Stromal Tumor: An Uncommon but Serious Cause of Gastrointestinal Bleeding.

Gastrointestinal stromal tumors (GISTs) are rare tumors of the GI tract that can sometimes present as a gastrointestinal bleeding source. This report describes a patient presented with upper GI bleeding secondary to a gastric GIST, which was initially detected on endoscopy. The patient underwent surgical resection of the tumor and was started on adjuvant chemotherapy with imatinib. The patient's postoperative course was complicated by an esophageal leak requiring re-exploratory laparotomy and esophageal stent placement. The stent was removed 5 weeks later and the patient remained stable for discharge after 60 days of inpatient care.

Left Ventricular Free Wall Rupture in Broken-Heart Syndrome: A Fatal Complication.

Takotsubo cardiomyopathy is usually a transient condition and is treated conservatively. It is rarely associated with ventricular free wall rupture, a fatal complication of the disease described in this report. Cardiothoracic surgery performed emergent ventricular wall repair; however, treatment was unsuccessful, and the patient expired.

Cavernous Hemangioma: A Rare Cause of Massive Lower Gastrointestinal Bleeding.

Due to their rarity, intestinal hemangiomas are not commonly considered as a cause of gastrointestinal (GI) bleeding. This report describes a patient who presented with massive, recurrent lower GI bleeding secondary to a cavernous hemangioma of the small intestine. The source of GI bleeding could not initially be identified despite using numerous diagnostic modalities. The lesion was eventually revealed on diagnostic laparoscopy and small bowel resection was performed.
