A rare case of bronchogenic cyst in a newborn baby

Bronchogenic cyst is a rare congenital anomaly of the formation of the pulmonary germ, a thin-walled formation filled with thick contents, which distinguishes it from aerial bronchial cysts. Clinically, a bronchogenic cyst can manifest itself as obstructive respiratory failure, swallowing disorders, and lead to recurrent purulent-inflammatory processes. In this article, we present a clinical case of bronchogenic cyst in a newborn child, detected during pregnancy at the 2nd ultrasound screening and successfully operated on as planned. A 5-day-old boy was transferred to a surgical hospital for surgical treatment of cystic formation of the left lung S10 with dimensions 16.0×12.0×15.0 mm; the cyst contents were homogeneous, corresponding to the fluid. Surgical treatment was performed - the formation was separated from the parietal pleura and sent to the pathology department for histological examination. No complications were observed in the postoperative period. The macroscopically studied object was a three-dimensional formation of gray-red color with a bluish tinge of irregular shape, dull, with a dark red fine sprinkling. A thin-walled cavity filled with cloudy jelly-like contents was determined on the incision. Microscopic description - a cyst lined with ciliated epithelium, partially flattened to cubic due to dystrophic changes, subepithelial islets of mature cartilage tissue and small groups of mucous glands. Thus, a bronchogenic cyst was morphologically verified. Differential diagnosis of bronchogenic cysts from inflammatory lung diseases (tuberculosis, abscess) with untimely diagnosis in the absence of clinical manifestations is practically impossible without histological examination. Therefore, prenatal diagnosis and morphological examination of the surgical material are crucial.
