Patient's question:
The onset time is unclear, no symptoms, accidentally found a pink nodule at the base of the tongue. Went to the hospital for examination, initially diagnosed as papilloma requiring surgical removal. The removed tissue consisted of an outer layer of membrane with calcified tissue inside, similar to teeth. The doctor then diagnosed it as calcified squamous cell carcinoma. Is it calcified squamous cell carcinoma? Can calcified squamous cell carcinoma grow on the tongue?Doctor's answer:
Calcifying epithelioma is a cell tumor derived from the differentiation of epidermal hair follicle cortex, containing basophilic cells and shadow cells, with shadow cells originating from basophilic cells. In new lesions, there are more basophilic cells, while in old lesions, there are fewer or even no basophilic cells. The lesion is located in the deep dermis or subcutaneous tissue, belonging to a deep-seated benign tumor of the skin. It rarely occurs on the tongue.
