Paraneoplastic erythrocytosis in a malignant ovarian steroid cell tumour.

Neoplastic polycythemia is a condition in which high hematocrit levels result from a neoplastic lesion in the body. It is a rare condition and occur because of excess erythropoietin or androgen production by the neoplastic cells. Steroid cell tumours of the ovary though notorious for producing endocrine changes in the body have rarely been associated with polycythemia. We present the case of a post menopausal lady who developed polycythemia and features of virilisation. Further investigations revealed that she had steroid cell tumour of the left ovary. Her signs and symptoms resolved after surgical removal of the tumour.
