	*Diagnosis:*	HYPEREOSINOPHILIC SYNDROME	*Category:*	reactive erythema / cutaneous sign of systemic disease / hypersensitivity
	*Body Site:*	total body / arm	*Age:*	40 years
	*Contributors:*	Daniel Chang Chris Bengson
	*Description:*	scattered widely disseminated 0.5-1.5 cm red plaques with dusky centers
	*Comments:*	A 40-year-old woman, who was diagnosed with hypereosinophilic syndrome, was admitted on multiple occasions for angioedema of face, throat, hands, and legs, diffuse abdominal pain, and urticarial edematous plaques on her arms, trunk, and thighs. She complained of itching and then burning pain in skin lesions which persisted for 2-3 days and recurred episodically. Acute symptoms were controlled with high dose oral steroids and antihistamines. The hypereosinophilic syndromes are a heterogeneous group of disorders characterized by three common features: peripheral eosinophil count of > 1500/無 for longer than six months, evidence of end organ involvement (excluding benign eosinophilia), and absence of other causes of eosinophilia (drugs, parasites, malignancy). Skin involvement is seen in 50% of patients. Typical cutaneous features include urticaria and angioedema as well as fixed urticarial papules and plaques. Treatment of the eosinophilia usually results in improvement in cutaneous and systemic symptoms.

	*Diagnosis:*	INSECT BITE REACTION / PAPULAR URTICARIA	*Category:*	environmental injury / hypersensitivity / linear eruptions
	*Body Site:*	leg / back	*Age:*	4 years
	*Contributor:*	Bernard Cohen, MD
	*Description:*	uniform edematous papules with central crusting and hypopigmentation and peripheral hyperpigmentation grouped in a linear pattern
	*Comments:*	This healthy 4-year-old girl developed a chronic and recurrent pruritic papular eruption on exposed areas particularly the legs 6 months ago. The lesions began as edematous red papules many with a central vesicle. Scratching led to central crusting and hypopigmentation with a surrounding hyperpigmented ring.
