Multicentric reticulohistiocytosis in a patient with severe preeclampsia.

A multigravida patient with polyarthralgia and eruptions on the head and fingers was seen at 6 weeks' gestation. No histological examination was performed before the current pregnancy. She developed severe early onset preeclampsia associated with swelling of the knees and increased cutaneous nodules, biopsies of which revealed multicentric reticulohistiocytosis. At 28 weeks' gestation an elective cesarean section was performed and a 580-g male infant was delivered.
