Contrary to common opinion the intraepithelial cancer of the buccal mucosa presents clinical symptoms, but they are discreet and different from those observed in an invasive carcinoma. Usually, there is leucoplakia with an erythema and an irregular keratosis or a punctuated one. There is an erythematous variation (Queyrat's erythroplasia) which is without keratinasation. Only histological evidence can confirm the diagnosis cancer. It should be differentiated against Bowen's disease and the light, intermediated and severe dysplasias.
与普遍观点相反，颊黏膜上皮内癌会出现临床症状，但这些症状并不明显，且与浸润性癌所观察到的症状不同。通常会出现伴有红斑的白斑，以及不规则角化或点状角化。有一种无角化的红斑变体（凯腊增殖性红斑）。只有组织学证据才能确诊癌症。它应与鲍恩病以及轻度、中度和重度发育异常相鉴别。
