Seborrhea (Seborrheic dermatitis)





Patient will present with generalized, fine, scaling
(flaky) rash of the scalp, ear, nose, and occasionally
lips.

embarrassed about her weight and wants to try
to loss some weight. She also would like to talk
about a rash that she has had for a long time.

On her physical exam you see this.
Intertrigo



Contact irritant dermatitis where candida is a
common fungus that causes this rash.
Occurs along the folds where there is a lot of
moisture making it an ideal location for fungus to
grow.

Mr. Powers is a 43 yo male who is coming to your

“irregular circular” pattern. He says that he has
had it for the past 6 months but he came in
because it just keeps getting worse. He denies
any itching and no trauma. You review his
medication and he is taking Lipitor, allegra-D,
accupril, Glucophage, and glipizide.
When you do your physical exam you see this
Necrobiosis lipoidica
Rash is commonly seen in diabetics
15% Precedes the onset of diabetes
25 % occur at the onset of diabetes
60% will occur in patients already diagnosed
Etiology- 3 theories
1. Diabetic microangiopathy secondary to glycoprotien
deposition.
2.Vasculitis- secondary to immunoglobulin deposition along
with complement/fibrinogen deposits
3. Abnormal Collagen- defective collagen has been seen in
other diabetic end organ damage
Treatment: Topical & intralesional steroids. ( atrophy of skin),
Aspirin & Dipyridamole (Anti-platelet therapy, platelet induced
vasocclusion disease.
Your next patient is a 28 yo male from the middle
east who speaks very little English. He’s at this
office visit with his wife who is able to translate.
She says that they are being referred to you from
another physician. Her concern is that her
husband has developed a medium size ulcer on
his ankle. It has been there for about 4 months,
but it has gotten worse. The wound is now
draining purulent discharge.

been having problems with his “bowels” for which
his wife says that he is taking a special
medication for his bowel problem.
Pyoderma Gangrenosum





2 types: Classic PG- involving primarily the legs.
Atypical PG- involves superficial skin, effecting the
hands
Diagnosis is based on exclusion by history/biopsy- DDx
is infection, connective tissue dz, vasculitis, trauma
Cause: speculated to be related immune dysregulation
Prognosis is good, associated with other systemic dz:
IBD, rheumatoid arthritis, chronic hepatitis, Wagener's
Treatment: Mild- topical steroid. Moderate-Severe:
Oral steroid, cyclosporin, methotrexate, and tacrolimus
Mrs.Lenning is a 36 yo female who is bringing her
4month old infant in for well child check. The only
concern on this visit is about breast feeding. She
claims that she has been having some difficulty
with breast feeding. She has noticed that there is
a dry rash around her areola on her right breast.
She has tried some Hydrocortisone cream on it
because she thought it was eczema but the rash
did not improve
When you do her physical exam you see this
Paget’s disease of the breast
1.Eczematous rash is pathoneumonic for the
presence of intraepithelial breast adenocarcinoma
2.Diagnosis-confirmed by punch biopsy,showing
Paget cells-(adenocarcinoma cells).
3. Prognosis: depends on the stage of disease (+)
lymph nodes vs localized disease.
4.Treatment option:masectomy (rarely), breast
conserving surgery(nipple-areoloa resection),
Conserving surgery + whole breast irradiation
provided the lowest % with recurrence
You have been consulted to see a 67 yo female S/P
right knee replacement for a possible wound
infection of the right knee.She is complaining of
right knee swelling, tenderness, and skin
hyperpigmentation. Her surgery was approx 1 week

trauma to this leg, no fever, no chills, no other
systemic symptoms


What questions do you want to know about her
post-op course.
Where you taking any Coumadin during her
recent hospitalization?
Coumadin Necrosis
Typically presents 7-14 days after administration of
coumadin.
Caused by Protein C deficiency: Bx will show fibrin thrombi within cutaneous
vessels leading to interstitial hemorrhage.
Clinically: Rash will develop over the trunk, arms, breast, and penis
(common symptom).
Treatment: Stop Coumadin, Protein C need to be replaced.(concentrated or
FFP), surgical debridement if rapidly progressing necrosis.
Once a patient has experienced this drug induced necrosis, Is it safe to try
the patient back on Warfarin?
Yes, Patient can be placed back on Warfarin but these patient need to be
closely monitor. If a patient has previously had a skin reaction to
coumadin there is no contraindication for subsequent doses
