Paleness: Or something else? Differential Diagnosis

Respiratory System (J00-J99)

Blood, blood-forming organs – immune system (D50-D90).

Anemia (anemia)
Iron deficiency anemia (anemia that occurs due to iron deficiency).
Hemolytic anemia – forms of anemia (anemia) characterized by increased degradation or decay (hemolysis) of erythrocytes (red blood cells), which can no longer be compensated for by increased production in the red bone marrow.

Endocrine, nutritional and metabolic diseases (E00-E90).

Malnutrition
Hyperinsulinism – presence of elevated insulin levels in the blood (fasting insulin > 17 mU/l).
Hyperprolactinemia – pathological (pathological) increase in the level of prolactin.
Hypoglycemia (low blood sugar)
Kwashiorkor – lack of protein in the diet; among the most severe forms of malnutrition.
Malnutrition (malnutrition)
Malnutrition
Malnutrition in old age
Marasmus – most severe form of malnutrition; also referred to as protein-energy malnutrition (PEM).
Porphyrias – group of rare metabolic diseases in which the formation of the red blood pigment heme is disturbed due to an enzyme defect.
Malnutrition
Wasting – describes the simultaneous and unintentional loss of muscle (body cell mass) and body weight due to inadequate nutrient (macro- and micronutrient) intake or severe illness. Particularly affected are people with liver disease, patients in intensive care units or with immunodeficiencies such as AIDS.

Skin and subcutaneous (L00-L99).

Neurodermatitis (atopic eczema)
Scleroderma – group of rare diseases associated with leathery connective tissue hardening of the skin. The disease belongs to the collagenoses (chronic inflammatory autoimmune diseases of connective tissue).

Cardiovascular system (I00-I99)

Atrioventricular block – cardiac arrhythmia belonging to the group of conduction disorders.
Cardiac arrhythmia
Heart failure (cardiac insufficiency)
Hypotension (low blood pressure)
Myocardial infarction (heart attack)
Myocarditis (inflammation of the heart muscle)
Raynaud’s syndrome (synonyms: Raynaud’s disease, Raynaud’s disease, white finger disease) – circulatory disorders of the hands or feet caused by vasospasm (vasospasm).
Sinuatrial block – cardiac arrhythmia belonging to the group of conduction disorders.

Infectious and parasitic diseases (A00-B99).

Mouth, esophagus (food pipe), stomach and intestines (K00-K67; K90-K93).

Gastrointestinal bleeding (GI bleeding; gastrointestinal bleeding).
Celiac disease – chronic disease of the small intestinal mucosa due to hypersensitivity to the grain protein gluten.

Neoplasms – tumor diseases (C00-D48).

Gastric carcinoma (stomach cancer)
Hodgkin’s disease – malignant neoplasia (malignant neoplasm) of the lymphatic system with possible involvement of other organs.
Myelodysplastic syndrome (MDS) – group of heterogeneous (inconsistent) diseases of the bone marrow (stem cell diseases).
Pheochromocytoma – neuroendocrine (affecting the nervous system) catecholamine-producing tumor of the chromaffin cells of the adrenal medulla (85% of cases) or sympathetic ganglia (nerve cord that runs along the spine in the thoracic (chest) and abdominal (stomach) regions)
Neuroblastoma – malignant neoplasia (malignant neoplasm) of the autonomic nervous system.
Tumor diseases, without further details

Psyche – nervous system (F00-F99; G00-G99)

Epilepsy (seizure disorder) – here as a vegetative symptom in the context of a focal seizure.

Symptoms and abnormal clinical and laboratory findings not elsewhere classified (R00-R99).

Cachexia – emaciation of the organism (emaciation) due to profound disturbance of one or more organ functions.
Shock

Genitourinary system (kidneys, urinary tract – reproductive organs) (N00-N99)

Renal insufficiency – refers to a process that leads to a slowly progressive reduction in kidney function.
Vulvovaginal atrophy/urogenital menopause syndrome (here: pallor of the mucosa 91%).

Causes (external) of morbidity and mortality (V01-Y84).

Injuries, poisoning, and other consequences of external causes (S00-T98).
