- Bluish (Cyanosis)
The skin is rosy, warm, and elastic, having no continuity defects.
When examining the skin by inspection and palpation we concentrate
on colour, moisture, temperature, turgor, presence of pathological efflorescence,
bleeding manifestations, and oedemas.
||Pallid appearance of the skin of the whole body (together with pallid mucous membranes) - accompanies anaemia or diffuse vasoconstriction (shock);
- pallid appearance of the skin is the sign of blood
circulation disorder e.g. in limbs (ischaemic ailment of the legs,
diabetic microangiopathy) or in individual fingers (Raynaud's
||The red coloration of the whole body surface - in hyperaemia (sun exposed skin, fever);
||Local hyperaemia (inflammation);
||Facial rubeosis (diabetes mellitus);
||Mitral stenosis - rosy-violet cheeks;
||Maragnon's maculae on face and the upper half of the body (neurovegetative lability in girls);
||"Palmar erythema" reddening of thenar and antithenar in cirrhotic patients;
||"Flush" is observed on the upper part of the body, particularly in faces of patients suffering from carcinoid (serotonin secretion).
||Bluish colour (cyanosis) can be observed on the skin and mucous membranes. The skin acquires the bluish colour, if concentration of reduced haemoglobin reaches 50 g/l.
cyanosis is caused by insufficient oxygen saturation of
haemoglobin in pulmonary diseases and congenital heart
defects (left-right short cut). It can
be found on the skin of the whole body it is particularly
visible in lips, tongue, mouth mucous membranes, and acral parts.
It is commonly found together with polyglobulia and clubbed
fingers. (Oxygen inhalation reduces cyanosis of pulmonary origin.)
||Peripheral cyanosis is caused by prolonged tissue-blood contact caused by insufficient blood circulation. It accompanies heart failure; it can appear in cold. It is observed in lips, ears, hands, feet (including toenails), the tongue is rosy.
is caused by increased plasma concentration of bilirubin. According
to the cause the following types of icterus can be distinguished:
praehepatic (haemolytic), hepatic (hepatocellular), posthepatic
(obstructive). In addition to the skin, sclera and palatial
mucous membrane are also affected.
is caused by hypercarotinaemia. The coloration is manifested
on the palms, soles, and cheeks (diabetes mellitus, hyperlipoproteinaemia).
||Brown colour generally arises from melanin accumulation or in combination with other substances.
||Localised form - nipples, linea alba and chloasma uterinum during gravidity.
||Diffuse form - after sunbathing, in porphyria, hyperthyroidism.
Addison's disease (peripheral form) manifests
by diffuse skin hyperpigmentation (except palms and soles, where only
ripples are coloured). There are graphite maculae
on mouth mucous membrane.
||Grey-brown - the skin takes part in melanin and haemosiderin accumulation, e.g. in haemochromatosis.
||Albinism is caused by lack of pigmentation in skin, hair, and irises. Hair and irises have light colours, the pupils seem to be bright red.
Vitiligo and leukoderma are caused by local loss of pigmentation. Those disorders are either congenital, or acquired - e.g. syphilis.
Enhanced moisture depends on enhanced perspiration.
in armpits, on palms, and soles, occurs in people with neurovegetative
dysbalance, commonly accompanied by acrocyanosis and acrohypothermia.
on the whole body surface is present in lytic temperature decrease,
thyrotoxicosis, shock, and hypoglycaemia. Nocturnal sweating can be
related to malignant tumours and tuberculosis.
||Localised form occurs in ischaemia.
||Diffusion form can
be found in dehydration and cachexia. The skin is dry and wrinkled
and peels off.
Body temperature depends on the blood supply of the skin, it can
be tentatively assessed by touch of hand.
||Locally decreased temperature
is characterised by pallid; cold skin (could be cyanotic) as a result
of impaired blood supply (ischaemic disease of blood vessels of lower
extremities, Raynaud's disease).
||Locally increased temperature
is characterised by reddening and oedema of the skin and is caused by
inflammation (erysipelas, thrombophlebitis).
Face cyanosis -
Sclera and face
cannot be found on the skin of a healthy person. Its presence
is the sign of a skin disease or can be the secondary manifestation
of the infectious or internal disease. Dermatological
terminology is used for describing.

Findings can transform continuously. Exact description, localisation, and configuration, and even the dynamics of the disease are required for judgement.
Some diseases are accompanied by distinctive findings:
Scarlet fever (scarlatina): small-macular red
exanthema is localised on the skin of the abdomen, it spreads
onto the legs and the rest of the body; it does not appear
at the vicinity of the mouth.
If untreated, the disease can lead to skin exfoliations.
Measles (morbilli): macular exanthemas localised
initially on the face and neck; they tend to merge together later.
There are so called Koplik's spots
at the mucous membrane of the mouth.
Chickenpox (varicella): begins as a macular,
later vesicular exanthema on the surface of the whole body (including
areas with hair), gradually it dry out. Eruption of efflorescence runs in
Shingles (herpes zoster): vesicular, later pustular efflorescences
are arranged in the groups that follow peripheral nerves route, but
also branch of the nervus trigeminus. The disease is caused by
the varicella - zoster virus in adult patients weakened by other diseases
Cold sore (herpes labialis, nasalis): vesicular
or pustular efflorescences are found on the lips, below the nose
or by the nose orifices in febrile diseases (croupous pneumonia, viral
infections), or in insolation.
Allergic exanthemas take the form of either urticarial
(nettle-rash) exanthema or their appearance may resemble findings present
in infectious diseases. In that case, they are called according to the disease
they resemble (e.g. morbiliform, scarlatiniform etc.) Itchy white or rosy
buds of a map-like appearance are typical for urticaria. Allergic exanthemas
manifest as local affections, most commonly caused by direct contact (plants,
cosmetics), or generalised affections of various appearance - on the skin
of the trunk and limbs. They tend to mingle and their eruption is recurrent
Transient oedematous swelling on the face, neck, or perhaps other areas is the sign of Quincke's oedema.
Erythema nodosum are specific painful red and
violet infiltrates located on the shanks (sarcoidosis, idiopathic intestinal
inflammations, or the origin may be unclear).
"Butterfly exanthema" is distinguished by symmetrical reddening of the face that is distinctively shaped (lupus erythematosus).
Osler nodes are bright, red coloured lentil size
nodes, which can be found on the fingertips. They are caused by mycotic
micro-embolisation in infectious endocarditis.
Various morphological findings in the form of petechiae, haematomas,
maculopapular efflorescences, or area infiltrations can all represent evolutionary
changes of vasculitis.
Xanthelasma is a shallow protruding area on the eyelid, close to the nose. It is caused by the accumulation of fat (hyperlipoproteinaemia, rarely in a healthy person too).
Xanthoma (tuberosum) is generally larger, commonly located on the muscle
tendons (some hyperlipoproteinaemias).
"Naevus arachnoideus" (spider angioma) is red,
made of a central arteriole wrapped by venules into periphery. Usually,
they are located in the upper part of the trunk and in the face.
In more advanced cases of hepatic cirrhosis they can appear on the arms
as well (they may appear non-specifically e.g. during pregnancy). When subjected
to pressure they become anaemic.
Haemangiomata are most commonly of lentil appearance,
but also they may be of irregular shape, at various locations in elderly

Petechiae are ecchymoses, dotty haemorrhages in thrombocytopenia, thrombocytopathia, and vasculitis.
Purpura arises of multiplex petechiae.
Haematoma has its origin in substantial subcutaneous
bleeding in case of e.g. coagulopathy. They gradually decolourise over time
(haemophilia, incorrect anticoagulation therapy, blunt trauma, hepatic cirrhosis).

depends on hydration of the skin, the epidermis and its structure.
Decreased turgor is common in older age and is caused by decreased elasticity
In other cases dehydration caused by fluid loss contributes to decreased
turgor (decompensated diabetes mellitus, diabetes insipidus, intensive diuretic
therapy) or dehydration can be caused by insufficient intake of fluids (reduced
thirst feelings in elderly people). The combinations of both causes
are frequent, too.

Oedemas are caused by an accumulation of extracellular fluid in the interstitium.
Local or generalised oedemas can be recognised.
||Inflammatory oedemas appear in the site of inflammation. The oedema is painful; the skin is warm and erythematous.
||Venostasic oedemas occur in the blockage
of the venous system (phlebothrombosis).
The skin is taut, sensitive, palpation causes a shallow
dimple; cyanosis can be observed.
||Lymphoedemas are caused by
the obstruction of lymaticph vessels or nodes by tumours, metastases,

can be found anywhere in the body, including mucous membranes
(Quincke's angioneurotic oedema, contact allergy, insect stings).
They tend to be flat, painless; they keep the colour and temperature
of the surrounding skin. Even eyelid oedemas in patients with
acute glomerulonephritis are considered of allergic origin.
Systemic oedemas occur in case of massive fluid
retention. From etiopathogenetic point of view there is various participation
of venostatic constituent, hypoproteinaemia and changes of vessel wall permeability.
||Cardiac oedema occurs in
case of the right heart insufficiency. In walking patients they
constitute in area perimaleolaris; they advance to the shanks
and thighs. In recumbent patients they are found on the shanks,
the lower part of the thighs and in the loins. In the most
severe cases they stretch to the abdominal area and they affect
the outer genitals. Ascites, hydrothorax, or hydropericarditis
occur. The state is called anasarca.
||Renal oedemas can be found
in nephrotic syndrome. They occur on the eyelids,
in the face, on the genitals, and in lumbosacral parts of
||Hepatic oedemas manifest
in decompensated hepatic cirrhosis. Ascites is predominant, but lower

has typical appearance and position depending on the sex.
||Thin hair can be found in both sexes in hypogonadism,
hypopituitarism, hypothyroidism, and hepatic cirrhosis
and in males treated by oestrogens.
||Stronger and denser hair (hypertrichosis,
hirsutism) is important in women. Mild forms
can be observed in older women on the face and in case of Cushing's
syndrome. More severe forms accompany androgenic tumours of the adrenal
cortex and androgen treatment (doping!).
is diffuse or local loss of hair. It occurs in cytostatic treatment,
in abdominal typhus, and thyrotoxicosis. In some men, the diffuse
alopecia is a common finding. Local alopecia (alopecia areata)
is rather rare to find.

and sideropenic anaemia.
||Spoon-shape bent nails (koilonychia) occur in thyrotoxicosis.
||Spherical nails accompany
congenital heart disorders, chronic pulmonary diseases; less frequently
can be found in hepatic cirrhosis as a part of clubbed fingers
(the shape of wrist watch glass).

in hepatic cirrhosis (the white part of the nail, so called
lunula occupies a significant part of the nail area).
