An ultrasound of the affected area showed a complex cystic mass measuring 3.9 x 2.9 x 3.7 cm within the subcutaneous fat (Figure 1(a)). While the mass abutted underlying muscular fascia, there was no extension into the underlying trapezius muscle itself (Figures 1(b) and 1(c)).
Representative sections of the bronchogenic cyst on routine H&E stain. (a) Low-power view of the subcutaneous cystic lesion (50x magnification) and (b) high-power view of the cyst wall, containing ectopic ciliated respiratory epithelium (arrow), smooth muscle (star), and small mucous glands (triangle) (200x magnification).
