Erythromelalgia associated with hypertension and leukocytoclastic vasculitis in a child.

Erythromelalgia is an acrocyanotic rheumatic disease presenting with erythema, and pain and a burning sensation in the hands and feet; it is rarely encountered during childhood. Hot or warm conditions may precipitate pain and erythema in the extremities and the symptoms may regress upon the application of cold water. The disease is usually secondary to other systemic diseases in adults. On the other hand, it is idiopathic in children. This article describes a case of erythromelalgia presenting with leukocytoclastic vasculitis and hypertension in a 7-year-old child who responded to therapy with prednisolone and phenoxybenzamine.
