Atypical presentation of a common condition.

Cow's milk protein allergy (CMPA) presents a wide range of clinical manifestations. Although gastrointestinal symptoms are common, they are not always present. In this report, we present two cases of infants with atypical CMPA presentations.

A Pediatric Gastric Dieulafoy Lesion: A Case Report and Literature Review.

This report presents a case of a 16-year-old male with severe upper gastrointestinal bleeding caused by a Dieulafoy lesion (DL). A DL is a rare but life-threatening condition characterized by sudden and massive bleeding from a small arterial vessel in the gastrointestinal (GI) tract. Diagnosis is often made through esophagogastroduodenoscopy (EGD), which reveals an enlarged submucosal blood vessel.

Pulmonary artery sling: An uncommon cause of stridor.

Pulmonary artery sling is a rare congenital condition often associated with congenital tracheal stenosis. Untreated pulmonary sling carries a high morbidity and mortality, most of which is due to the airway and other associated anomalies rather than the aberrant artery itself. We report the case of an infant presenting progressive respiratory distress after a viral infection.
