Course: Multiple Yellowish Plaques in a Cobblestone Pattern on the Tongue

CME Credits: 1.00

Released: 2022-11-02

A man in his 80s with a medical history of gastric adenocarcinoma treated with total gastrectomy presented with asymptomatic lesions on his tongue that gradually developed during the previous 3 months. Intraoral examination revealed multiple yellowish to erythematous papules and verrucous cobblestone-like plaques on the mucosal surface on both sides of his tongue (, A and B). The skin of the face, neck, arms, and other sun-exposed areas did not reveal any associated lesions. He reported occasional alcohol intake, and there was no history of tobacco-related habits or oral trauma. The results of laboratory investigations, including a complete blood cell count, serum chemistry panel, liver and kidney function test, C-reactive protein levels, lipid profile, and serum and urine electrophoresis disclosed no abnormalities. With the clinical suspicion of squamous cell carcinoma, an incisional biopsy was performed (, C and D).
