The work is based on an analysis of the course of the disease in 185 patients with squamous cell skin cancer. The study program included studies in three major groups. The first included 74 (40%) patients who underwent combined treatment: an operation involving widespread excision of a tumor under intravenous anesthesia + photodynamic therapy (group 1). The second group was 111 (60%) patients with squamous cell carcinoma of the skin who received only operative treatment. To control and compare the obtained laboratory indicators, a second group was created, which included patients without established pathology. This group included 17 people who voluntarily agreed to conduct the study. The study traced the dynamics of changes in hemostasis scores and metalloproteinases in the two groups being compared. In the group of patients with squamous cell skin cancer, there was a statistically significant decrease in the metalloproteinase-1 inhibitor index, which led to an increase in all metalloproteinase-2, -7 and -9 indicators. Performing surgical treatment did not lead to correction of these indicators, both in the near and distant periods after treatment. The mechanism of influence of photodynamic therapy in squamous cell skin cancer can be characterized as follows: there is a decrease in the inhibitor of metalloproteinase-1, which leads to an increase in matrix metalloproteinases-2, -7 and -9 in the blood, as a result of damage to the endothelium of the vascular wall, which is confirmed by an increase in endothelin, this, in turn, led to the development of vasoconstriction and increased procoagulant activity The use of photodynamic therapy restores the index of metalloproteinase-1 inhibitor, this leads to the restoration of matrix metalloproteinases-2, -7 and -9 in the blood and the prevention of damage to the vascular wall. Comprehensive treatment of patients with squamous cell skin cancer in the initial stage of the disease should include photodynamic therapy with simultaneous intravenous blood irradiation, laser tumor training, and then surgical treatment, consisting in excision of the tumor with observance of oncological principles.

The incidence of skin cancer is a steady increasing around the world. Tumors of epithelial origin occupy the first place in the structure of all skin malignancy. Epidermoid carcinoma is the most malignant epithelial tumor of the skin and mucous membranes with squamous differentiation. Generally, squamous cell carcinoma is successfully treated by surgical and radiological methods. Often a different kind of plastic defect reconstructions are required after surgical removal. The incidence of epidermoid carcinoma increases with age (average age of patients falls on 65 years) therefore variants of treatment options is limited by comorbidities. However, surgical oncologist do not have enough date and randomized controlled studies on this theme. Minimally invasive methods, especially cryothechnology are increasingly used, but unfortunately their advantage requires additional evidence. We suppose Inclusion in the conventional treatment of new technologies may possibly improve the results of treatment. We reviewed the literature, summarizing data on various methods of treating squamous cell skin cancer. Comprehensive and systematic search was based on MedLine, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Scopus and PubMed among original articles for the period from January 1974 to October 2018.

Background: Ultraviolet (UV) radiation is known to be an important etiologic agent in the development of skin cancer. Keratoacanthoma is an unusual, well-described cutaneous neoplasm that resembes squamous cell carcinoma but spontaneously resolves. Rarely, multiple keratoacanthomas may develop. Objective We present a case of multiple keratoacanthomas in a patient with psoriasis who had received UVB phototherapy. These lesions were hyperkeratotic papules, many of which spontaneously resolved and demonstrated the histologic characteristics of keratoacanthoma. Conclusion: We believe that UV radiation is the most likely etiologic factor in this patient's development of multiple keratoacanthomas. We wish to bring to the attention of clinicians this unusual adverse effect of UV treatment.
