The depth of a stage 4 pressure ulcer varies by anatomical location. The bridge of the nose, ear, occiput and malleolus do not have (adipose) subcutaneous tissue and these ulcers can be shallow. Stage 4 ulcers can extend into muscle and/or supporting structures (e.g., fascia, tendon or joint capsule) making osteomyelitis likely to occur ...
An ulcer is a sore on the skin or a mucous membrane, accompanied by the disintegration of tissue. Ulcers can result in complete loss of the epidermis and often portions of the dermis and even subcutaneous fat. Ulcers are most common on the skin of the lower extremities and in the gastrointestinal tract. An ulcer that appears on the skin is ...
The most common presentation is a single large, deep ulcer (although several smaller ulcers may occur) in the internal surface of one or both labia minora. [11] The labia majora may be affected, as may the vagina and urethra. The ulcer develops very quickly, and is usually preceded by sudden onset of fever and malaise. [11]
Within these components are the pilosebaceous units, arrector pili muscles, and the eccrine and apocrine glands. [8] The dermis contains two vascular networks that run parallel to the skin surface—one superficial and one deep plexus—which are connected by vertical communicating vessels.
Ulcer: An ulcer is a discontinuity of the skin exhibiting complete loss of the epidermis and often portions of the dermis. [32] [33] Fissure is a lesion in the skin that is usually narrow but deep. [29] [33] Induration is dermal thickening causing the cutaneous surface to feel thicker and firmer. [29]
Aphthous ulcer, a specific type of oral ulcer also known as a canker sore; Peptic ulcer, a discontinuity of the gastrointestinal mucosa (stomach ulcer) [1] Venous ulcer, a wound thought to occur due to improper functioning of valves in the veins; Stress ulcer, an ulcer located within the stomach and proximal duodenum
Ulcers occur on exposed parts of the body, primarily on anterolateral aspect of the lower limbs and may erode muscles and tendons, and sometimes, the bones. [3] These lesions may frequently develop on preexisting abrasions or sores sometimes beginning from a mere scratch.
A venous ulcer tends to occur on the medial side of the leg, typically around the medial malleolus in the 'gaiter area' whereas arterial ulcer tends to occur on lateral side of the leg and over bony prominences. A venous ulcer is typically shallow with irregular sloping edges whereas an arterial ulcer can be deep and has a 'punched out' appearance.
