Our patient's painful oral lesions were highly suggestive of secondary syphilis: depapillary erythematous patches on the dorsal aspect of the tongue (also known as plaques en prairie fauchee) and a split papule on the oral commissure (also known as fausse perleche or false angular cheilitis) [11, 15, 18-22].
Median rhomboid glossitis, angular cheilitis (perleche), and often chronic atrophic candidiasis are mixed bacterial/fungal microflora (Holmstrup & Axell, 1990; Shay et al., 1997) (see Table 3 for a clinical description of each type).
