Colorectal liver metastasis with intrabiliary growth: case report and review of the literature.

abstract：:Pseudofungi are septate hyphae-like structures very similar morphologically to true fungal elements. Histologically their presence poses a diagnostic challenge as they mimic fungal infection. Accurate identification of pseudofungi is required to avoid unnecessary treatment, and this can be accomplished by careful morp...
