Sarcoidosis, or subcutaneous sarcoidosis, is a rare skin disease characterized by the formation of hard nodules on the skin that resemble sarcomas. This review will discuss the etymology, clinical picture, differential diagnosis, and also propose the main methods of treatment for subcutaneous tissue sarcoids.
The disease was first described at the beginning of the 20th century. A systematic description of the disease was proposed by Dr. W. Cord in 1904. Sarcoids of subcutaneous tissue are characterized by the appearance of bright purple nodes located in various areas of the skin.
The classic description of subcutaneous sarcoid: normally the skin has a uniform color and a smooth surface. When the disease occurs, fairly dense nodes appear on its surface, sometimes reaching significant sizes (diameter 5-30 cm). They have the shape of round formations, under the skin they are filled with adipose tissue and rarely contain a fibrous structure. On a cut, the node is a tissue with small air bubbles, which resembles the stratum corneum of the skin. Sarcoid nodules can be solitary or occur in groups. Differential diagnosis must be made with dermatofibromas, nevi, chalazions, boils, lymphomyelomatosis, connective tissue diseases, tumors of the skin and other organs. Treatment for subcutaneous sarcoid depends on many factors, for example, the age of the patient, the nature of the disease, the presence of complications, etc. Conservative treatment can also be prescribed, it can include ointment dressings, thermal procedures, and surgical methods can also be used, and special nutrition is prescribed.
