1. MUCOCELE (MUCUS EXTRAVASATION
PHENOMENON)
Rupture of a salivary gland duct and spillage of mucin into the
surrounding soft tissues result s of local trauma.
Unlike the salivary duct cyst it lacks an epithelial lining.
Although sometimes salivary duct cysts is reported under the
classification of retention mucocele.
CLINICAL FEATURES:
Mucoceles typically appear as dome-shaped mucosal swellings that
can range from 1 or 2 mm to several centimeters in size. often
imparts a bluish translucent hue to the swelling, although deeper
mucoceles may be normal in color. Characteristically it is fluctuant.
Age:
children and young adults.
perhaps because younger people are more likely to experience
trauma that induces mucin spillage.
Location: The lower lip is by far the most common site for the
mucocele.
- Less common sites include the floor of mouth (ranulas:5.8%)
- not a single example was identified
from the upper lip. This is in contrast to salivary gland tumors, which
are not unusual in the upper lip but are distinctly uncommon in the
lower lip.
HISTOPATHOLOGIC FEATURES:
spilled mucin surrounded by a granulation
tissue response.
TREATMENT AND PROGNOSIS:
Some mucoceles are short-lived lesions that rupture
and heal by themselves. Many lesions, however, are
chronic in nature, and local surgical excision is necessary.
