sialoadenitis simple flash cards in pathology histology, clinical sign , history , scenario of salivary gland lesions

1. Inflammation of the salivary glands can
arise from various infectious and noninfectious causes. The most
common viral infection is mumps
Location: Salivary Glands ( Minor, major).
Age: depending on exposure to the etiology
Etiology:
-Viral infection
-Most bacterial infections
arise as a result of ductal obstruction or decreased salivary
flow, allowing retrograde spread of bacteria
throughout the ductal system
CLINICAL Features:
The affected gland is swollen and painful, and the overlying.
skin may be warm and erythematous. An associated low-grade
fever and trismus may be present. A purulent discharge often is
observed
from the duct orifice when the gland is massaged.
HISTOPATHOLOGIC FEATURES:
accumulation of neutrophils is observed within the ductal
system and
acini. Chronic sialadenitis is characterized by scattered
or patchy infiltration of the salivary parenchyma by
lymphocytes and plasma cells. Atrophy of the acini feature ductal
dilatation. If associated fibrosis is
present, then the term chronic sclerosing sialadenitis is used.
TREATMENT AND PROGNOSIS:
The treatment of acute sialadenitis includes appropriate
antibiotic therapy and rehydration of the patient
to stimulate salivary flow. Surgical drainage may be
needed if there is abscess formation.
Early cases that
develop secondary to ductal blockage may respond to
removal of the sialolith or other obstruction.

2. A 70-year-old female patient was referred to department of Oral Medicine
and Radiology with a chief complaint of a swelling in left side of neck since
12 days and pain in swelling since 10 days. Pain was increased in intensity
while swallowing. Patient gives no history of fever and difficulty in eating
and speaking. Patient noticed that initially swelling was initially small in
size and gradually increase to present size of 4-3 cm. The patient’s medical
history was unremarkable
