A simple method using whole slide imaging can be used to quantify and compare histochemical staining. This method could be deployed in routine quality assurance and quality control. Work is needed on whole slide imaging devices to improve reproducibility.

Periscapular location of bronchogenic cysts is extremely rare with four cases reported in literature. We report a relatively late presentation in a ten-year-old boy that was clinically mistaken for a typical sebaceous cyst. The definitive treatment is total excision after preoperative imaging to detect the occasional intrathoracic extension. Histologically they are lined by pseudostratified ciliated columnar epithelium, which can rarely undergo malignant transformation.
