- Α-Thalassemia (HbH disease, hydrops fetalis/generalized fluid accumulation); incidence: mostly in Southeast Asians.
- Β-Thalassemia: most common monogenetic disorder worldwide; incidence: People from Mediterranean countries, Middle East, Afghanistan, India and Southeast Asia.
- Thrombocythemia – strong multiplication of blood platelets.
Endocrine, nutritional and metabolic diseases (E00-E90).
- Amyloidosis Amyloidosis – extracellular (“outside the cell”) deposits of amyloids (degradation-resistant proteins) that can lead to cardiomyopathy (heart muscle disease), neuropathy (peripheral nervous system disease), and hepatomegaly (enlargement of the liver), among other conditions
- Calciphylaxis (synonym: uremic calcifying arteriolopathy, UCA; metastatic calcification) – severe and painful progression of bone loss due to renal disease (renal osteodystrophy).
- Diabetes mellitus (diabetes) with wound healing disorders: eg, diabetic foot or diabetic foot syndrome.
- Dysproteinemia – disorder of the protein balance in the blood, in which there is a quantitative disproportion between the plasma proteins.
- Malnutrition (deficiency of: Protein (albumin), vitamin C, folate, iron, selenium, zinc).
Skin and subcutaneous (L00-L99).
- Decubital ulcers (pressure ulcers) in immobilization/decubitus.
- Necrobiosis lipoidica – inflammation of the middle dermis with accumulation of lipids leading to necrosis (tissue death) (1% of diabetics; about 60% of patients with such a skin disease have diabetes mellitus)
- Pyoderma gangraenosum – painful disease of the skin in which there is ulceration or ulceration (ulceration or ulcer) and gangrene (tissue death due to reduced blood flow or other damage) over a large area, usually in one spot
- Ulcus cruris venosum – lower leg ulcer, which is caused by venous insufficiency (2/3 of cases).
Cardiovascular system (I00-I99)
- Angiodysplasia (vascular malformations).
- Lymphatic drainage disorders
- Peripheral arterial occlusive disease (pAVK) – progressive stenosis (narrowing) or occlusion (closure) of the arteries supplying the arms / (more often) legs, usually due to atherosclerosis (arteriosclerosis, arteriosclerosis).
- Ulcus cruris arteriosum – lower leg ulcer, which is due to arterial occlusive disease.
- Ulcus cruris hypertonicum – ulcer of the lower leg, which is caused by inferior supply of the tissue with blood due to angiolitis (vascular inflammation).
- Ulcus cruris mixtum – lower leg ulcer, which is caused by a combination of arterial and venous circulatory disturbance.
- Ulcus cruris varicosum – lower leg ulcer, which is caused by varicose veins.
- Vasculitides (vascular inflammation) such as in the context of periarteriitis nodosa or pyoderma gangraenosum (painful disease of the skin, in which it comes over a large area, usually in one place, to an ulceration or ulcer (ulceration or ulcer) and gangrene (tissue death due to a reduction in blood flow or other damage).
- Vasculopathy as in cholesterol emboli, calciphylaxis, necrobiosis lipoidica.
Infectious and parasitic diseases (A00-B99).
- Skin infections, unspecified (e.g., mycobacteriosis, sporotrichiosis).
Musculoskeletal system (M00-M99).
Neoplasms – tumor diseases (C00-D48).
- Ulcerated neoplasms of the skin, unspecified (e.g., basal cell carcinoma (BCC; basal cell carcinoma), squamous cell carcinoma).
Psyche – nervous system (F00-F99; G00-G99).
- Alcohol abuse (alcohol dependence)
- Neuropathies – collective term for diseases of the peripheral nervous system.
Symptoms and abnormal clinical and laboratory findings not elsewhere classified (R00-R99).
- Gangrene – local tissue death; distinguish dry and wet gangrene.
