Dear Sir

Resolution of hepatoma usually causes liquefaction of clotted blood which may sometimes lead to blood tinged serum and discharge. As the lesion is healed , there seems to be no cause for concern.

Do get back to me if you need any further assistance, will be glad to assist you.

Take Care
