Hello and welcome to HCM
It would be nice if you could post the histopathology report too.
There is a clinical suspicion and radiological evidence of malignancy. However, no features of malignancy on biopsy
This could be due to biopsy from non-representative site.
A repeat biopsy should be done.
A diagnosis of malignancy on histopathology is a must because it is a 100% confirmatory test.
No treatment can be given on clinical suspicion or radiological evidence of malignancy.
So, repeating the biopsy from representative site.
But a word of caution, do get the slides reviewed from a second pathologist for a second opinion
Thanks and take care
