Signs and symptoms are dependent upon the type of<unk> . Often, apart from the appearance of the lesions, there are usually no other signs or symptoms. Most types of<unk>  are painless, but a burning sensation may<unk> cur in some cases.<unk>  can, therefore, sometimes be misdiagnosed as burning mouth syndrome. A burning sensation is more likely with erythematous (atrophic)<unk> , whilst hyperplastic<unk>  is normally entirely asymptomatic. Acute atrophic<unk>  may feel like the mouth has been scalded with a hot liquid. Another potential symptom is a metallic, acidic, salty or bitter taste in the mouth. The pseudomembranous type rarely causes any symptoms apart from possibly some discomfort or bad taste due to the presence of the membranes. Sometimes the patient describes the raised pseudomembranes as "blisters."<unk> casionally there can be dysphagia (difficulty swallowing), which indicates that the<unk>  involves the oropharynx or the esophagus, as well as the mouth. The trachea and the larynx may also be involved where there is<unk> , and this may cause hoarseness of the voice.
