A Rare Case of Lymphoproliferative Disorder in Pregnancy: A Case Report.

Lymphoproliferative disorders in pregnancy are rare. Among that, Castleman disease is an uncommon lymphoproliferative disorder in pregnancy with an unknown etiology. Many cases have not been encountered more often in practice and are easily misdiagnosed due to their rarity. We present a case of a 36-year-old pregnant woman with a left para-ovarian mass incidentally diagnosed during the elective caesarean section as a benign lymphoproliferative disorder, sent in frozen. Diagnosing Castleman disease in frozen histopathology is quite challenging for pathologists, and few cases have been reported.
