Increased blood pressure in the veins (venous hypertension) can cause diffusion of substances, including fibrin, out of capillaries. Fibrotic tissue may predispose the tissue to ulceration. Recurrent ulceration and fat necrosis is associated with lipodermatosclerosis. In advanced lipodermatosclerosis the proximal leg swells from chronic venous ...
Lipomas have a prevalence of roughly 2 out of every 100 people. [2] Lipomas typically occur in adults between 40 and 60 years of age. [1] Males are more often affected than females. [1] They are the most common noncancerous soft-tissue tumor. [5] The first use of the term "lipoma" to describe these tumors was in 1709. [6]
In the early stages, when the nodule is single and/or smaller, it is recommended to avoid direct pressure to the nodule(s). Soft inner soles on footwear and padding may be helpful. [5] MRI and sonogram (diagnostic ultrasound) are effective in showing the extent of the lesion, but cannot reveal the tissue composition. Even then, recognition of ...
A dermatofibroma, or benign fibrous histiocytomas, is a benign nodule in the skin, typically on the legs, elbows or chest of an adult. [3] It is usually painless. [3] It usually ranges from 0.2cm to 2cm in size but larger examples have been reported. [3] It typically results from mild trauma such as an insect bite. [3]
Venous leg ulcers due to impaired circulation or a blood flow disorder are more common in the elderly. Rare causes of skin ulcers include pyoderma gangraenosum, lesions caused by Crohn's disease or ulcerative colitis, granulomatosis with polyangiitis, morbus Behçet and infections that are usually seen in those who are immunocompromised, for ...
AFST tumors commonly present as slowly growing, painless, deep-seated lumps in individuals aged 6 to 86 years old (median age 47-50 years in different studies). [4] The tumors are most common in the lower extremities but uncommonly occur in the back, chest wall, iliac crest, groin and nearby lower lateral abdominal region, [4] abdominal cavity, pelvic cavity, [5] breast, [3] cheek, temporal ...
Superficial thrombophlebitis is a thrombosis and inflammation of superficial veins presenting as a painful induration (thickening) with erythema, often in a linear or branching configuration with a cordlike appearance.
Pressure ulcers can trigger other ailments, cause considerable suffering, and can be expensive to treat. Some complications include autonomic dysreflexia, bladder distension, bone infection, pyarthrosis, sepsis, amyloidosis, anemia, urethral fistula, gangrene and very rarely malignant transformation (Marjolin's ulcer – secondary carcinomas in chronic wounds).
