Aortopulmonary window (APW) is an uncommon congenital cardiac malformation, accounting for 0.1% of all congenital cardiac diseases. It is a defect between the ascending aorta and the trunk of the pulmonary artery. Such abnormality may occur as an isolated lesion or it can be associated with other cardiac abnormalities in one third to one half of cases. Clinical and hemodynamic presentation of this condition depends on the size of the defect and on the associated lesions. It is usually fatal in infancy or childhood if untreated with the development of irreversible pulmonary hypertension. Once the diagnosis is made, surgery must be performed quickly to avoid irreversible pulmonary vascular disease. We report the case of a 5-month-old infant with APW who was referred to our center by respiratory symptoms and heart murmurs.

Solitary mastocytoma is the most common form of mastocytosis in children. The main symptom is pruritus. The treatment is symptomatic and it’s based on Topical corticosteroids. The prognosis is good with possibility of spontaneous regression at adulthood. This case report is about a 7-month-old infant that presented with an erythromatous papular lesion on the left temple. The patient responded well to topical steroids and antihistamines.
