Acne disease in germ cell tumors. A brief review of the literature and a description of our own clinical observation

malignant neoplasms (MNP). The frequency of PNS in MNP ranges from 1 to 20 % according to different authors. One of the manifestations of PNS is acne, which occurs against the background of malignant neoplasm due to hormonal disorders.The presented article describes a clinical case of a patient with a mixed germ cell tumor and metastases in the retroperitoneal lymph nodes. The germ cell tumor produced human beta-chorionic gonadotropin, which led to the development of acne as a PNS.Antitumor treatment (surgical removal of the tumor and polychemotherapy) normalized the levels of human beta-chorionic gonadotropin and serum testosterone, which in turn led to regression of acne without acne therapy.
