A Case Report of an Unusual Presentation of a Pedunculated Gastrointestinal Stromal Tumor: Acute Upper Gastrointestinal Bleeding in a 57-Year-Old Female.

Gastrointestinal stromal tumors (GISTs) are rare tumors accounting for 0.1-3% of gastrointestinal (GI) neoplasms.  In the past, GIST was classified as leiomyomas, leiomyosarcomas, and leiomyoblastomas. However, now it is evident that GIST is a separate tumor entity, and it is the most frequent sarcoma of the GI tract. We report a case of a 57-year-old female with a five-day history of black tarry stools, two episodes of vomiting of dark-colored blood, dizziness, abdominal pain, night sweats, and palpitation, provoked by a change of position. After a computerized tomography (CT) of the abdomen and pelvis, a GIST was suspected, which was confirmed with histopathology. Acute upper GI bleeding is a rare presentation of GIST. Clear guidelines should be developed for GIST. An early diagnosis is crucial for a better prognosis.

Congenital pulmonary airway malformation complicated by aspergilloma: A rare adulthood presentation - Case report.

Congenital Pulmonary Airway Malformation (CPAM) is an uncommon condition in adults, which typically presents as acute fever and lung abscesses caused by bacterial infections. We present a case of a 39-year-old female with a CPAM in the upper lobe of the right lung, complicated by an aspergilloma, who presented with a history of hemoptysis. The patient underwent an upper lobectomy and is symptom-free in follow-up. 2012 Elsevier Ltd. All rights reserved.
