Spontaneously healing pyogenic liver abscess.

We have presented an unusual case of pyogenic liver abscess due to gamma streptococci group D, which remained undiagnosed for about seven months, and which ruptured spontaneously into subcutaneous tissue, resulting in self-cure. Despite the large hepatic abscess seen on liver scan and ultrasound, results of liver function tests remained normal. A mass seen on liver scan or ultrasound in patients with a malignancy does not necessarily indicate metastasis, and a more aggressive approach is required to treat a potentially curable disease.
