General Discussion
** REMINDER **
The information contained in the Rare Disease Database is provided for
educational purposes only. It should not be used for diagnostic or treatment
purposes. If you wish to obtain more information about this disorder, please

section of this report.
Fissured Tongue can be either a hereditary condition or it may be
acquired. This disorder is characterized by irregular markings of the
surface of the tongue.
Symptoms
Fissured Tongue is characterized by a division into lobules, convolutions,
and ridges on the tongue that resemble the skin patterns of the scrotum. The
markings on the back of the tongue are exaggerated, and knoblike projections
(fungiform papillae) may be prominent. The grooves tend to radiate from the
central depression of the tongue, resembling the ribs of a leaf. It is
probably a secondary phenomenon, caused by the topography of the underlying
muscle bundles. Pain in the tongue (glossodynia) sometimes occurs with this
condition.
Causes
Fissured Tongue may occur in an acquired form or a hereditary form. In the
hereditary form the disorder is transmitted as a probably autosomal dominant
trait. (Human traits including the classic genetic diseases, are the product
of the interaction of two genes for that condition, one received from the
father and one from the mother. In dominant disorders, a single copy of the
disease gene (received from either the mother or father) will be expressed
"dominating" the normal gene and resulting in appearance of the disease. The
risk of transmitting the disorder from affected parent to offspring is 50%
for each pregnancy regardless of the sex of the resulting child.) This type
of Fissured Tongue may also be associated with other primary conditions such
as Acromegaly, Down's Syndrome, or Geographic Tongue.
(For more information on these disorders, choose "Acromegaly", "Down",
and "Geographic Tongue" as your search terms in the Rare Disease Database.)
When the disorder is acquired it may be caused by infections such as
syphilis, scarlet fever, or typhoid fever.
Affected Population
Fissured Tongue can affect persons of both sexes, and all ethnic groups.
Related Disorders
Hairy Tongue is a disorder characterized by yellowish, brownish, blackish, or
bluish discoloration of the tongue, with excessive growth of the threadlike
elevations (filiform papillae) in front of the tastebuds. A bad taste in the
mouth usually also occurs.
Geographic Tongue is an inflammation of the tongue that may go into
remission and recur again. This form of inflammation is characterized by
migrating denuded smooth areas (excoriations) on the tongue which may feel
slightly sore and sometimes itchy.
(For more information on the above disorders, choose "Hairy Tongue" and
"Geographic Tongue" as your search terms in the Rare Disease Database.)
In Moeller's Glossitis, the tongue is slick, glossy, or glazed. The
lesions are very distressing and persistent.
Median Rhomboid Glossitis is a developmental lesion of the tongue. This
lesion consists of a smooth, reddish, nodular area on the back portion of the
middle third of the tongue.
Severe Acute Glossitis can occasionally be caused by local infection,
burns, or injury to the tongue. This type of Glossitis may develop rapidly,
producing marked tenderness or pain with swelling. The swelling may be
sufficient to cause the tongue to block air passages in the most severe
cases.
Therapies: Standard
In Fissured Tongue, oral hygiene is very important to keep the ridges in the
tongue free of foreign matter that might otherwise cause inflammation. The
symptoms of Fissured Tongue may disappear spontaneously.
Therapies: Investigational
