Extensive cellulitis is known as:
1. Phlegm
2. Phlegmon
3. Cellulitis majora
4. Cellulitis prima
Pathology Answer: 2
Extensive cellulitis is most accurately described by the term "phlegmon
Phlegm is a thick, viscous substance produced by the respiratory tract,
especially during a respiratory infection, which can be coughed up from the
lungs or expelled from the nose. It is primarily composed of mucus, dead cells,
and other substances.
Phlegmon is a term that is closely related to extensive cellulitis. It refers
to a severe form of cellulitis where the infection has spread deeply into the
subcutaneous tissues and is accompanied by significant inflammation, including
the presence of pus and necrosis. Phlegmon is characterized by intense pain,
swelling, redness, and warmth in the affected area. This condition often
requires aggressive medical management, including intravenous antibiotics and
surgical drainage if an abscess forms. It is an advanced and severe stage of
cellulitis that can lead to systemic infection if not treated properly.

Which of the following diseases of the skin is the most likely to exhibit fluid blisters on the skin and/or oral mucosa?
1) Pemphigus
2) Lichen planus
3) Keratosis follicularis
4) Erythema multiforme
Oral Pathology
Answer: 1
Pemphigus is an autoimmune blistering disease characterized by the formation of bullae (fluid-filled blisters) on the skin and mucous membranes, including the oral mucosa. This condition occurs when the body's immune system mistakenly attacks the proteins that bind the layers of the skin together, leading to separation and blistering. The blisters are usually large and painful, and they can rupture easily, leaving raw, exposed areas of skin or mucous membrane.
Lichen planus, keratosis follicularis, and erythema multiforme are other skin conditions but do not typically present with fluid blisters as the main feature.
