Description

Introduction

While malignancy associated hypercalcemia is a common finding among 20% to 30% of adult patients with breast cancer, lung cancer and multiple myeloma, it happens in less than 5% of female genital tract malignancies. [1] The three most common mechanisms associated with hypercalcemia are: local osteolytic hypercalcemia, humoral hypercalcemia of malignancy (HHM) caused by the parathyroid hormone-related peptide (PTHrP), and other humoral factors including prostaglandin, tumor necrosis factor (TNF), osteoclast activating factor and transforming growth factor (TGF). PTHrP and 1, 25 dihydroxy vitamin D (1, 25 Vit D) have been reported as humoral factors for dysgermininoma. [2] Humoral hypercalcemia of malignancy (HHM) can be caused by ectopic paraneoplastic production of 1, 25 dihydroxy vitamin D due to hyperactivity of 1 alpha-hydroxylase enzyme.
