The Black Hairy Tongue (BHT) is characterized by a hypertrophy of lingual papillae in the posterior part of the back of the tongue which often take a brown to black coloration; its etiology is unknown but probably multifactorial: alcohol-smoking, poor hygiene prolonged use of antiseptics or oral antibiotics, digestive and metabolic disorders, etc. We report two observations of BHT where the diagnosis of candida was retained following the detection on several samples of the same species and the good clinical evolution under suitable antifungals. P atient aged 53 years, having as antecedent pathological a taking of cortico therapy for an eczema problem in the feet, the port of dentures with bad oral hygiene that presents itself for a brownish color in the tongue with no functional discomfort, no feeling of impasto or itching. The patient was put under Flagyl, canaflucan and protected amoxicillin without clinical improvement. Microbiological examination was performed, direct examination after culture showed the presence of yeasts. The culture on Sabouraud medium made it possible to isolate a candida. The identification using the gallery 20 C AUX objectified candida glabrata. The patient is put under Nystatin with a good clinical and biological evolution. P atient 67 years old, diabetic, chronic smoking, checked up for heart failure under stent, with dentures and excessive hygiene of the oral cavity. The one whounderwent a dermatological consultation for brownish coloring of the tongue, the diagnosis of BHT is retained. The mycological study confirmed the diagnosis of candida lusitaniae. The patient was put on nystatin tablet with good clinical progress. The purpose of our work was not to highlight a causal link between candida and the occurrence of this pathology but its incrimination in the process or maintenance of this lesion.
