Unusual presentation of a cutaneous bronchogenic cyst in an asymptomatic neonate.

Cutaneous presentations of bronchogenic cysts are rare in all age groups. Previous reports of cutaneous manifestations of bronchogenic cysts have been described as nodular, adherent masses, most frequently with a suprasternal location. We report a unique presentation of an infant with a pedunculated, anterior chest wall mass, which was identified as a bronchogenic cyst.

Radiology-Pathology Conference: Mature teratoma arising from an intra-abdominal undescended testis in a 7-month-old infant.

We report a rare case of an intra-abdominal testicular mature teratoma in a 7-month-old male infant presenting with a palpable abdominal mass and unilateral undescended testis. We describe the pathology, clinical presentation, and imaging findings of this entity. Clinical features accompanied by characteristic radiologic findings guide a provisional diagnosis that is confirmed by histologic analysis following surgical removal of the tumor. The pathogenesis and radiologic findings of testicular mature teratomas in the prepubertal population share many similarities to that of mature ovarian teratomas commonly seen in females of reproductive age. Awareness of this entity will permit the radiologist to suggest timely diagnosis and intervention when presented with a similar case.

Radiology-pathology conference: incidental posterior mediastinal ganglioneuroma.

We report the radiology and pathology findings on a patient with an incidental posterior mediastinal ganglioneuroma and review the literature on this uncommon tumor.

Radiology-Pathology Conference: choledochal cyst.

We report the radiologic and pathologic findings of a newborn with a choledochal cyst and review the etiology, diagnostic considerations, and management of this entity.
