Henoch-Schönlein syndrome. Unusual manifestations with hydrops of the gallbladder.

Henoch-Schönlein Syndrome (HSS) is characterized by the presence of purpuric skin lesions, colicky abdominal pain, renal manifestations, and arthritis. We report a case complicated by several unusual manifestations, including hydrops of the gallbladder and extreme thrombocytosis. Gallbladder hydrops has been known to occur in association with several conditions including Kawasaki syndrome, scarlet fever, and leptospirosis, but no previous report of this occurring in a patient with HSS could be found. The hydrops in our patient resolved spontaneously without specific medical or surgical treatment.
