Parkes Weber syndrome presenting as Stewart-Bluefarb acroangiodermatitis.

Parkes Weber syndrome (PWS) is a rare disorder characterised by arteriovenous (AV) fistula, along with capillary, lymphatic, venous malformations and limb hypertrophy. Stewart-Bluefarb syndrome is a variant of acroangiodermatitis, which is associated with congenital AV malformation/fistulas. It usually begins early in life, unilaterally over lower extremities presenting as violaceous to dusky coloured macules, papules or plaques with tendency to ulcerate. We are reporting a case of AV malformation fulfilling the triad of PWS and presenting with acroangiodermatitis. © BMJ Publishing Group Limited 2019. No commercial re-use. See rights and permissions.
