Congenital cystic lesions of the lung are uncommon and a conjunction of two or more lesions is very rare. We report here on a case of coexisting intrapulmonary bronchogenic cyst and congenital cystic adenomatoid malformation in a 13-year-old female with a cystic mass in the right upper lobe of the lung. Computed tomography showed a cystic lesion measuring 2.5 cm with an air fluid level and surrounding multicystic lesions in the right upper lobe. On gross examination, the cut surface showed a cystic mass containing inspissated mucinous material, and the cystic mass was surrounded by multiple small cysts. Microscopically, the larger cystic cavity was lined with pseudostratified ciliated columnar epithelium. The submucosal tissue contained mucinous glands and plates of cartilage. The surrounding smaller cysts or irregular spaces were lined with bronchiolar-type respiratory epithelium. We propose that this hybrid lung lesion may represent the missing link in a common embryologic pathway determined by the timing of mesenchymal and epithelial interactions.

Abstract PDF: Bronchogenic cyst is an uncommon congenital anomaly that arises from maldevelopment of the primitive foregut, and is usually found in the lung and mediastinum. Cutaneous or subcutaneous bronchogenic cysts are rare, and occur especially in the shoulder region. We report here on a 40-year-old woman with a soft, nontender, cystic mass on the upper posterior aspect of the right acromioclavicular joint; this had been recognized about 20 years before. She underwent incision and drainage of the lesion at a local clinic about 1 year ago, but the wound was not healed. MRI showed an irregular-shaped dark signal intensity lesion that measured 2 x 1.5 cm in the subcutaneous fat layer. Microscopically, the cyst was lined by pseudostratified ciliated columnar epithelium that displayed squamous metaplasia. The cyst wall revealed frequent smooth muscle bundles, occasional seromucous glands and multifocal lymphocytic infiltration. This is the first reported case of subcutaneous bronchogenic cyst of the shoulder in a Korean adult.

Abstract PDF: Bronchogenic cyst is usually an extrapulmonary cyst formed as the result of an accessory lung bud from the foregut that becomes isolated from the rest of the tracheobronchial tree producing a usually solitary cyst. Most bronchogenic cysts are in the mediastinum with rare occurrence on the subcutaneous tissue over the sternum. We report a case of cutaneous bronchogenic cyst that occurred in the skin over the sternum in a 13-month-old boy. On ultrasonography, a well circumscribed non-echogenic cystic mass was observed measuring 1.5x1.3 cm. Histologically, the cyst was lined by cilicated, pseudostratified, columnar epithelium with interspersed goblet cells, and there were bundles of smooth muscle fibers, mucous glands, and lymphoid aggregates in the cyst wall.
