Abstract:
Thymomas are associated at a high frequency with paraneoplastic autoimmune diseases. We treated a 64-year-old male with a thymoma, who also had lichen planus. The tumor was resected and diagnosed as thymoma, however, the symptoms associated with lichen planus did not subside and persisted. A preoperative examination showed an elevated serum level of squamous cell carcinoma antigen, which gradually decreased to normal after surgery. The findings of this case are interesting for understanding the correlation between a thymoma and autoimmune abnormalities.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

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.
