Berardinelli-Seip Syndrome and Essential Thrombocytosis: An Unusual Association.

Congenital generalized lipodystrophy (Berardinelli-Seip syndrome) is an autosomal recessive condition, presenting during infancy with generalized loss of fat. We report a 30-year-old female patient with diabetes who has acromegaloid features, prominent umbilicus, prominent muscles, prominent subcutaneous veins, and gross hepatomegaly. Near-total loss of subcutaneous fat was confirmed by whole-body magnetic resonance imaging and laboratory data revealed significant hypertriglyceridemia, uncontrolled diabetes mellitus, and heavy proteinuria with stage IIIa chronic kidney disease. Her blood film revealed thrombocytosis that on further evaluation by bone marrow biopsy was confirmed to be a myeloproliferative neoplasm (MPN); essential thrombocytosis (ET). She also had skin lesions that were proven to be reactive perforating collagenosis and necrobiosis lipoidica diabeticorum. She was managed conservatively and received interferon injections with fair general condition and control of her ET. However, her kidney function deteriorated furthermore to stage V chronic kidney disease requiring regular treatment with hemodialysis. We believe this is a unique case of Berardinelli-Seip syndrome with MPN that could be a coincidental association or part of a new syndrome.
