Cheilitis Granulomatosa and Cheilitis Glandularis

Cheilitis Granulomatosa 

    Definition 

         Inflammation of the lip.


    Clinical picture 

         Chronic firm swelling, affecting usually
            one lip but sometimes both.

         Usually, the upper lip is affected.

    Etiology 

         It may occur due to  allergy to some factors as:

             Cosmetics.

             Food.

             Oral hygiene products (e.g. tooth paste, mouth rinses).

             Dental restorative materials.

       

     NB 

         When cheilitis granulomatosa is combined with facial paralysis  and fissured tongue it is

            called Melkersson -Rosenthal syndrome.

Cheilitis Glandularis 

  Definition 

     Rare inflammatory condition affecting minor salivary glands of the lower lip.

  Etiology 

     The etiology is uncertain although several etiologic factors have been suggested as:

         actinic damage (chronic sun exposure), infection, and tobacco irritation.

  Clinical Features 

     Cheilitis      glandularis   is  characterized   by   swelling   and  eversion   of   the   lower   lip   due   to

        hypertrophy and inflammation of the labial salivary glands.

     The orifices of the minor salivary ducts are dilated and inflamed giving the labial mucosa a

        red macular appearance. 

     Malignant transformation may occur  in the overlying epithelium of the lip.
