Answer
- Acute Lymphadenitis ( of the submandibular lymph nodes ).
- large infected cut wound on the left check -- infection is carried by lymphatics reach regional lymph nodes ( Submandibular lymph nodes , along the left side of the front of the neck ) - the Submandibular lymph nodes are infected ( tender, swollen, red, hot & firm or soft ).
Work Step by Step
1. Lymphatic Drainage of the Face including the Nose,
Cheeks ( left & right ) & upper Lip
drain into the buccal & submandibular nodes.
( i.e. left check - submandibular nodes ).
2. Acute Lymphadenitis
- infection is carried to lymph nodes along the lymphatics
from an inflamed focus.
- usually the regional lymph nodes are infected,
sometimes , the infection " jumps " to a more distant
group of lymph nodes.
- the common organisms are streptococci &
staphylococci but any other organism can affect the
lymph nodes.
# Pathology :
the nodes are enlarged , congested, edematous &
the cut section shows infiltration with Leucocytes.
Periadenitis may occur.
# Complications :
1- Spread to more proximal Lymph nodes.
2- Spread to nearby tissues.
3- Suppuration ( abscess formation ).
4- the organism may remain dormant in the lymph
nodes & flare up every now & then.
# Clinical Picture :
1- the picture of the causative lesion.
2- General constitutional manifestations as fever,
rigors, & headache.
3- Locally the nodes are enlarged, red, hot, tender,
firm or soft & if suppuration occurs, fluctuation will
be evident.
the intervening Lymphatics between the causative
focus & affected lymph nodes may be seen as red
streaks which are tender ( Lymphangitis ).
# Treatment:
- the treatment of the causative focus may cure the
the inflamed nodes.
- General rest & antibiotics are advised & local heat
are applied.
- if an abscess forms, an incision is required.
