How would you manage a case of subcutaneous panniculitis-like T cell lymphoma (A/B) who is already on steroids and methotrexate for autoimmune disease?
First, I would want to be assured that the diagnosis is truly panniculitis T cell lymphoma and not lupus profundus. The two can be hard to differentiate microscopically with T cell gene rearrangement positive in the lymphoma. If the diagnosis is lupus profundus, this would be managed as per rheumato...
In which patients with suspected IgA nephropathy and microalbuminuria would you recommend a kidney biopsy?

In proteinuric patients, with intact kidney function, threshold proteinuria (UPCR) of 0.5 g/g, or UACR <300 mg/g would be an indication to biopsy. In diseases such as IgA Nephropathy, treatment is driven by the degree of proteinur...
