Abstract:
A 59-year-old man consulted our hospital because of an abnormal shadow on a chest X-ray without any symptoms. A chest computed tomography (CT) revealed growing pulmonary nodule in the right lower lobe. Benign lung tumor was suspected and the patient underwent right lower lobe partial resection. Pathological examination demonstrated the tumor to be pulmonary papillary adenoma within round atelectasis.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
