Snus (nass) and oral cancer: A case series report
A 35-year-old female was referred urgently having presented to her general medical practitioner complaining of an ulcer on her tongue of about 2-month duration. The patient was complaining of an ulcer on the right side of her tongue, which had previously been asymptomatic but had begun to cause occasional discomfort as it increased in size. The ulcer was interfering with the patient's ability to eat. Previous medical history revealed that the patient was suffering from hyperthyroidism. Otherwise, her medical history was clear, and the patient had a snus habit for the previous 3 years in the right mandibular lingual vestibule. Intraorally, there was evidence of a crater-like ulcer (prominent border and depressed base) on the right lateral border of the tongue extending into the dorsal surface of the tongue with a diameter of 6 cm, which was tender and indurated [].\nAn incisional biopsy was performed, which revealed poorly differentiated squamous cell carcinoma histopathologically. CT revealed two abnormal nodes in the right submandibular region, which were needle-biopsied; metastatic squamous cell carcinoma was detected. Following surgery and radiotherapy the patient survived for only 5 months.
