Skin Signs of Systemic Disease Flashcards
What are some reasons why there are different skin findings and give some examples
Endogenous pigment – Addison’s Exogenous pigment - Argyria Metabolic – Thyroid and Diabetes Nutritional – Vitamin deficiencies Genetic Structural – Ehlers-Danlos Abnormal signal – GI cancer syndromes (Gardner’s) Infiltration - Xanthomas Photo-related - Lupus
What are three “neurologic” skin disorders?
a. Seborrheic Dermatitis – A more severe form of common dandruff that can affect the scalp, face and even upper torso
b. Neurofibromas – skin, pink or tan to brown colored soft, rubbery, compressible papules
c. Angiofibromas
What are some endocrine-related skin conditions?
- Diabetes
- Hyperthyroidism
- Hypothyroidism
- Addison’s Disease
- Cushing’s Syndrome
What are some skin conditions related to diabetes?
Acanthosis Nigricans, Yellow skin, Brown patches on lower legs, Foot uclers (mal perforans)
List the cardiovascular-related skin disorders
Ehlers-Danlos: Some types at risk for aortic and valve disease
Endocarditis: Skin findings include splinter hemorrhages, purpura, nail fold changes,
(For Peds)PHACES Syndrome:
-Cardiac findings include aortic coarctation, atrial and ventricular septal defects
Marfan’s syndrome
What happens to your skin pigment with Addison’s disease?
It gets darker (see power point slide of two sisters)
How can stretchy skin in Ehlers-Danlos syndrome indicate heart problems?
Some types at risk for aortic and valve disease
What organ system is involved in Sarcoidosis, Scleroderma, Tuberculosis?
Pulmonary
What are some GI related diseases?
Pyoderma Gangrenosum: punched out ulcers that enlarge
Dermatitis Herpetiformis: gluten sensitivity
Excesses
Genetic: Gardner’s Syndrome, Muir-Torre Syndrome, Peutz-Jeghers
Vitamin deficiencies
Out of the 11 criteria for diagnosing lupus, name the four that can be diagnosed with a skin exam
- M–Malar rash ****
- D–Discoid rash ****
- S–Serositis
- O–Oral Ulcers ****
- A–ANA+
- P–Photosensitivity ***
- B–Blooddisorders
- R – Renal Involvement
- A – Arthritis (joint effusions can be seen)
- I – Immunologic
- N – Neurologic
***Usually presents with “mystery rash” on face
How can seborrheic dermatitis (A more severe form of common dandruff) inform of other diseases?
Seen with Parkinson’s, after head trauma, HIV(New onset severe), chronic neurologic conditions such as cerebral palsy
T/F: a good technique for expanding (Pyoderma Gangrenosum) ulcers is debridement
False
NEVER DEBRIDE, will only enlarge
Also, it is often associated with inflammatory bowel disease
How can skin findings of thickened skin over fingers and hands, skin tightening around mouth, and Raynaud’s, inform of other diseases?
Scleroderma
Commonly develop pulmonary hypertension, however pericarditis has poorest prognosis
Give examples of how renal diseases can show skin signs
a. Metastatic renal cancer commonly metastasizes to the skin and can be noted as a bright red, very vascular, rapidly enlarging lesion
b. Henoch-Schonlein Purpura – vasculitic lesions on legs that extend to buttocks classically (more than lower leg vasculitis) will commonly have renal complication of glomerulonephritis
How is Dermatitis Herpetiformis related to GI conditions?
Gluten sensitivity –skin shows extremely pruritic, pinpoint vesicles on extensor elbows, knees and sacrum, often excoriated and crusted when seen
