Posterior atrophic candidiasis is also known as:
When the posterior dorsal point of fusion of tongue is defective, a rhomboid-shaped, smooth erythematous mucosa lacking in papillae or taste buds is seen. This median rhomboid glossitis (central papillary atrophy, posterior lingual papillary atrophy) is a focal area of susceptibility to recurring or chronic atrophic candidiasis, prompting a recent shift towards the use of posterior midline atrophic candidiasis as a more appropriate diagnostic term.
