There are two types of EM:
 EM minor and EM major.
 EM minor comprises nearly 70% of the cases.
 Most cases of EM minor resolve in one to three
weeks
 EM major might take three to six weeks to resolve.
 Recurrences are more commonly seen in EM minor,
but are rare in EM major.
 Traditionally, Stevens- Johnson syndrome (SJS) and
toxic epidermal necrolysis (TEN) were included in
the same spectrum as EM.
EM MINOR
 Most patients with EM minor present with new-
onset mucocutaneous lesions which are usually
symmetrical and rapidly progressing in nature.
 These lesions may be pruritic or may be associated
with a burning sensation.
EM MAJOR
 EM major is usually preceded by prodromal
symptoms such as fatigue, fever, headaches, and
myalgias.
 These symptoms can appear up to two weeks prior to
the mucocutaneous manifestations.
 Oral mucosal involvement may lead to difficulty in
drinking and eating.
 Ocular involvement may lead to complaints of
redness, discharge and ocular pain.
Treatment
 Prevention is cornerstone of treatment if HSV can be
demonstrated as the trigger.
 Antiherpetic antibiotic
Fixed Drug Eruption
 the development of one or more annular or oval
erythematous patches as a result of systemic
exposure to a drug.
 normally resolve with hyperpigmentation and may
recur at the same site with reexposure to the drug.
Erythema Multiforme
Lesion
•Begin as sharply marginated,
erythematous macules, which
become raised, edematous
papules over 24 to 48 hours
•“target” or “iris” lesion with
3 zones – central dusky
purpura; an elevated,
edematous, pale ring; and
surrounding macular
erythema
Age of Predilection
Young adults
Site of Predilection
dorsal hands, dorsal feet,
extensor limbs, elbows and
knees, and palms and soles
Fixed Drug Eruption
•Begins as a red patch that
soon evolves to an iris or
target lesion identical to
erythema multiforme, and
may eventually blister and
erode
•Nonpigmenting fixed drug
eruption: large, tender, often
symmetrical eythematous
plaques
Oral and genital mucosa
Etiologic Factors
Treatment
Erythema Multiforme
Fixed Drug Eruption
Usually has non-drug causes,
most commonly herpes
simplex infection
Genetic susceptibility with an
increased incidence of HLAB22
•Prevention is cornerstone of
treatment if HSV can be
demonstrated as the trigger.
•Sunblock creams
•Antiherpetic antibiotic
•Stop taking the offending
drug.

Seborrheic Dermatitis
 also known as seborrhea
 common non-contagious condition of skin areas rich
in oil glands (the face, scalp, and upper trunk)

marked by flaking (overproduction of skin cells) and
sometimes redness and itching (inflammation) of the skin
 varies in severity from mild dandruff of the scalp to
scaly, red patches on the skin.
Seborrheic Dermatitis
 Epidemiology:
 with redness and flaking = 3–5% of the population
 affects all races; worse in men, and starts after puberty
(although babies have a version called cradle cap) and peaks
around the age of 40 and then may improve
 Cause:
 due to a combination of an over production of skin oil and
irritation from a yeast, Pityrosporum ovale.
 Risk:
 Stress, fatigue, weather extremes, oily skin, infrequent
shampoos or skin cleaning, use of lotions that contain alcohol,
skin disorders (such as acne), or obesity
 Familial

Leprosy
Spontaneous resolution can
occur in a few years, leaving

Progression can also occur,
leading to borderline-type
leprosy
Neural involvement is common leads to tender, thickened nerves
with subsequent loss of function

peroneal, ulnar, and radial
cutaneous and posterior tibial
nerves are often prominent
Nerve damage can happen early,
resulting in wrist drop or foot
drop
