NUTRITIONAL DEFICIENCIES
Iron and vitamin deficiency is one of the most common
deficiencies that affect the oral cavity including the
tongue. Chronic iron deficiency is associated with
Plummer Vinson syndrome where tongue is very
painful with burning sensation. The tongue is inflamed
and beefy red, smooth or bald due to atrophy of papilla,
hence called as Hunter’s glossitis (Fig. 12). Vitamin B12
deficiency associated with pernicious anemia results in
inflammation of the tongue with beefy red, atrophy of
papilla and soreness resulting in smooth tongue. The
tongue is severely affected by other vitamin deficiencies
like niacin deficiency (pellagra) results in black tongue
and riboflavin deficiency causes magenta tongue.
The treatment should comprise of first identifying
the underlying cause of the deficiency and then the
appropriate supplement should be given Mole On Tongue And NUTRITIONAL DEFICIENCIES.
NEOPLASM
Squamous cell carcinoma of the tongue is the most
common malignant tumor of the oral cavity in patients
younger than 40 years and is more common in men
than women.16 It is regarded as a biologically different
entity compared to cancer affecting other oral sites.
It is more aggressive and generally associated with a
higher rate of metastasis. It commonly involves the
mobile tongue i.e., anterior two-thirds of the tongue,
lateral borders followed by dorsum. It may arise
de novo or from an existing leukoplakia or irritation
from a sharp tooth or prosthesis. It is clinically silent
as there is laxity of the tissue planes separating the
intrinsic tongue musculature, which helps cancer cells
to spread easily and becomes symptomatic only when
tumor size interferes with tongue mobility. Despite,
the ease of inspecting the tongue by both patient and
physician, they often present late, as they are usually
painless and often ignored by the patient. Eventually,
they present as a nonhealing ulcer which, demonstrates
growth over time usually >2 cm at presentation, with
the lateral border being the most common site (Fig.
15). The patient may develop speech and swallowing
dysfunction and pain occurs when the tumor involves
the lingual nerve, and this pain may also be referred
to the ear.
