In the course of a routine dissection class for medical students, it was observed that there was no oblique fissure, cardiac notch, and lingula in an embalmed cadaver. Due to their absence, the superior and inferior lobes of this lung could not be distinguished clearly. The lobes were attached together, however, there were no structural variations in its hilum. No variation was found in the fissures and hilum of the right lung in this cadaver. We opine that this variation can be helpful to cardiothoracic surgeons, mainly during the resection of the lobe of the left lung.
