Oral carcinoma in situ in a middle-aged woman with systemic sclerosis: Report of a rare case and literature review
ORAL ONCOLOGY(2024)
Abstract
Systemic sclerosis (SSc) is a rare multisystem rheumatic autoimmune disease involving the skin, connective tissue, and internal organs. Individuals with SSc are at increased risk of cancer. We herein contribute by reporting a case of carcinoma in situ affecting the lower lip and labial mucosa of a 56-year-old Brazilian female patient, which apparently represents the first case reported in Latin America. Surgical resection of the lesion was performed. After a 2-year follow-up, the patient has shown no evidence of recurrence. According to a literature review in PubMed, Web of Science, Scopus, and Embase databases on SSc-related oral and oropharyngeal cancer, 11 cases have been documented hitherto. Reports of oral carcinoma in individuals with SSc are rare. Clinicians should conduct regular examinations of the oral mucosa of these individuals to permit an early diagnosis, as done in the present case.
