SKIN/RASHES Flashcards
HSV rash
is characterized by grouped vesicles on an erythematous base; the mother may have active lesions or a history of the disease. HSV is diagnosed via DFA or ELISA detection of HSV antigens, and acyclovir is given for treatment.
Transient neonatal pustular melanosis
Transient neonatal pustular melanosis is a rash that is described best as vesicopustules that rupture easily and leave a halo of white scales around a central macule of hyperpigmentation, generally seen on the trunk, limbs, palms, and soles. There is no definitive diagnosis, and no treatment is necessary as a resolution is spontaneous.
Henoch-Schonlein Purpura (HSP)
HSP is the most common vasculitis of children and is a leukoclastic vasculitis of the small vessels. For the majority of children, the prognosis is excellent. HSP can occur anytime from infancy (as early as 6 months old) to adulthood, with Caucasians having the highest incidence and African Americans the lowest incidence.
HSP is seen slightly more in males than in females and occurs more frequently in the fall and winter months, pointing to an environmental trigger, including viral infection. While an upper respiratory infection often precedes HSP, a clear association between an infectous agent and HSP has not been found.
