Adenoma Malignum Presenting With Profound Hyponatremia.

BACKGROUND

Adenoma malignum of the cervix (also referred to as minimal deviation adenocarcinoma) is a rare malignancy. Although previous reports have described adenoma malignum presenting with mucinous vaginal discharge, no reports to our knowledge have described a presentation with profound hyponatremia due to fluid losses.

CASE: We present a case of adenoma malignum in a 52-year-old woman who presented with substantial watery vaginal discharge and profound hyponatremia.

CONCLUSION

Despite being a rare cervical tumour, adenoma malignum should be considered in the differential diagnosis of watery vaginal discharge. This tumour can present with severe electrolyte disturbances.
