Developmental Anomalies : Median Rhomboid Glossitis; Etiology Clinical Features Oral Manifestations and Treatment
ETIOLOGY
The etiology is failure of retraction of the tuberculum impar before the starting of the fusion of the two halves of the tongue.
Candidal infection has been recently suggested because of isolation of fungal hyphae from the lesion.
CLINICAL FEATURES
It appears as a smooth red patch on the dorsum of the tongue.
It can be of various shapes like oval or round and sometimes irregular.
It does not contain filiform papillae.
HISTOLOGIC FEATURES
The epithelium is hyperparakeratinized type and is devoid of papillae.
The spinous cell layer is larger than normal due to proliferation.
The rete pegs are elongated and may show branching and anastomosis.
The connective tissue shows lymphocytic infiltration.
Blood vessels and lymphatics are increase in number.
Degeneration and hyalinization of the underlying muscles.
TREATMENT
There is no need for treatment.
Spontaneous remissions have been reported.
Nystatin and Amphotericin have shown good results in few cases.

Developmental Anomalies : Fibromatosis Gingivae; Etiology Clinical Features Oral Manifestations and Treatment
CLINICAL FEATURES
The disease is characterized by the diffuse nodular or smooth overgrowth of the gingiva.
One or both the arches can be affected.
The appearance of the gingival lesion coincides with the time of eruption of the central incisors.
Some times it has been noted at the time of birth.
It is neither painful nor hemorrhagic.
If it occurs before the eruption of the teeth it interferes with their eruption.
If it occurs after eruption then the growth is extensive enough to cover the crowns.
HISTOLOGIC FEATURES
The epithelium is thickened with elongated rete pegs. The dense fibrous connective tissue comprises the major bulk of the lesion.
The blood vessels are few in number.
TREATMENT
Surgery can be done to facilitate the eruption of the teeth.
Cosmetic reasons also require surgical approach.

Developmental Anomalies : Heck's Disease; Clinical Features Oral Manifestations and Treatment
CLINICAL FEATURES
It is also known as Focal Epithelial Hyperplasia.
It is mostly found in children between the age of 3 and 18 years.
The lesion occurs most commonly on the lips buccal mucosa and the tongue.
It has a sessile base and occurs in clusters.
It is soft and colour resembles that of the normal mucosa.
The size of the individual nodule is ranges from 1 – 5 mm.
HISTOLOGIC FEATURES
Acanthosis along with thickening elongation and fusion of the rete pegs has been reported.
The connective tissue shows inflammatory cells like polymorphonuclear leukocytes and lymphocytes.
TREATMENT
No treatment is required. Many cases have shown spontaneous regression.
