Cheilitis (inflammation of lips) should always be in hands of a specialist - dentist, since it may be transformed into a phlegmon that puts a patient into a serious risk. Thrombophlebitis v. angularis may spread into brain sinuses and cause a suppurative lepto-meningitis.


Anguli infectiosi (stomatitis angularis, painful lip angles) do not possess an immediate danger for a patient, although they usually signal a general illness. This disease is a concomitant sign of hypochromic anemia, ariboflavinosis, iron deficiency, diabetes, and also Sjögren’s and Plummer Vinson’s syndromes. It also affects people with lowered occlusion (lacking teeth or with a wrongly made denture), often in combination with candidiasis.


Glossitis (inflammation of the tongue) has a colorful etiology. At children, this disease may originate as a result of the tongue traumatization by a persistent coughing (e.g. in case of pertussis - whooping cough - a small ulcer at the tongue frenulum - Rig’s disease). Glossitis of an allergic origin (drugs induced) that are associated with formation of vesicles, ulceration an edema, are common. Glossitis often appears during a general sickness, but certain kind of inflammation of the tongue is rarely a pathognomonic sign of a particular disease. The tongue’s filiform papillae react in the most sensitive way (usually by atrophic changes) to alterations in an organism. Glossitis atrophica appears frequently during malignant anemia, Faber’s anemia, pellagra, ariboflavinosis and sprue. It is also a part of xerostomy accompanying Sjögren’s syndrome, severe diabetes, liver malfunctions and chronic colitis.


Lingua villosa nigra (black hairy tongue) is characterized by hypertrophy and coloration of the filiform papillae. It appears as a result of a long term treatment with antibiotics or oxidants.


Lingua geographica (map-like tongue) is characteristic by bounded smooth areas on the dorsum of the tongue. These areas are divided from those with a physiologic surface by a noticeable white edge. The surface picture changes during the course of the disease. At children, this phenomenon may be inherited and does not require any treatment, in adults it may appear in connection with gastrointestinal tract diseases.
