[Long-term glucocorticoid therapy and the rapid development of squamous cell carcinoma in systemic sclerosis: Is...

Systemic sclerosis (SSC) is an autoimmune disease associated with the risk of malignancies, especially lung cancer, among which adenocarcinoma and squamous cell carcinoma are the most frequent. A 63-year-old female patient with SSC was hospitalized due to blackouts, poor general condition, and changes in her fingers. Because of subsequent epileptic seizures resulting in weakness of the left side of her body, computerized tomography (CT) of the neurocranium was performed which showed metastatic lesions. A CT scan of the thoracic organs displayed pulmonary neoplasia in the right hilum, which were histologically evaluated as grade 2 squamous cell carcinoma. After one month of hospitalization with supportive therapy, the patient’s clinical condition improved, and she was discharged into home care with recommendations for further oncological treatment. However, the patient died several days later. In comparison to adenocarcinomas, squamous cell carcinomas of the lungs usually develop through a significantly longer period. We consider that the unusually rapid development of the carcinoma in this patient was stimulated by the immunosuppressive effect of high doses of glucocorticoids that she had been taking for several years on her own initiative.
