What causes this type of reaction?
Vaccinia (pox vaccine)
What disease can manifest this way?
Lepromatous leprosy (Mycobacterium leprae)
Note the neurotrophic atrophy
Elrichia (HME)
Notice morulae in cytoplasm of monocyte
Organism causing the disease described here?
Parvocirus - Erythema contagiosum
(flu-like illness followed by rash)
Molluscum contagiosum (pox virus)
RMSF
Notice rash on PALMS
Molluscum contagiosum
Borellia burgdorferi
Bulls eye rash (erythema chronicum migrans of initial LD)
What organism may cause this finding?
B. burgdeorferi
(tertiary lyme disease can cause erosive arthritis, especially of the knee)
