What is acanthosis of the epidermis?
Acanthosis is a thickening of the epidermis and elongation of the rete ridges due to thickening of the spinous layer +/- enlargement of rete pegs. Typical examples include chronic eczematous reactions.
What is acanthosis in mouth?
Malignant acanthosis nigricans (AN) is an uncommon paraneoplastic condition that can involve oral mucosa. Though usually associated with gastric carcinoma, associations with tripe palms and, more rarely, other carcinomas are possible.
What is acanthosis keratosis?
Actinic keratosis (AK) is a UV light–induced lesion of the skin that may progress to invasive squamous cell carcinoma. It is by far the most common lesion with malignant potential to arise on the skin. See the image below.
What is the difference between hyperkeratosis and acanthosis?
If the process becomes chronic, the edema regresses, and the epidermis becomes hyperplastic as a response to the chronic insult. Epidermal hyperplasia is seen as a thickening of the epidermis and elongation of the rete ridges (called acanthosis), accompanied by ortho or para-hyperkeratosis.
What is acanthosis and hyperkeratosis?
Acanthosis nigricans (AN) is a skin condition characterized by abnormally increased coloration (hyperpigmentation) and “velvety” thickening (hyperkeratosis) of the skin, particularly of skin fold regions, such as of the neck and groin and under the arms (axillae).

What is hyperplastic squamous mucosa?
Squamous hyperplasia is characterized by increased numbers of squamous cells resulting in increased thickness of the squamous epithelium, which may be diffuse or plaque-like or form blunt papillary projections. Hyperkeratosis is frequently seen with squamous cell hyperplasia.
Is squamous hyperplasia cancerous?
Diagnosing Squamous Cell Hyperplasia The condition is almost always benign and the risk of developing invasive cancer due to squamous cell hyperplasia is rare. Since squamous cell hyperplasia is similar to other nonmalignant vulvar conditions, your OBGYN may suggest a biopsy to confirm the diagnosis.
Does acanthosis go away?
How Is Acanthosis Nigricans Treated? Treating the underlying cause of acanthosis nigricans can make the dark patches of skin fade or even disappear.

What are some causes of esophageal squamous mucosa?
Squamous Cell Carcinoma Factors that cause chronic irritation and esophageal mucosa inflammation may increase the risk for esophageal squamous cell carcinoma. These factors include moderate-to-heavy alcohol drinking, smoking, achalasia, diverticuli, and consumption of extremely hot beverages, coarse grains or seeds, lye, and caustic spices.
What is squamous mucosa with squamous dysplasia?
Squamous hyperplasia of the oral mucosa is usually seen on the palate ( Figure 1, Figure 2, and Figure 3) or gingiva ( Figure 4). Squamous hyperplasia is characterized by increased numbers of squamous cells resulting in increased thickness of the squamous epithelium, which may be diffuse or plaque-like or form blunt papillary projections.
