INTRODUCTION: Incidentally discovered lung nodules can be worrisome for both the patient and their physicians. Although 95% of solitary lung nodules are benign, it is important to distinguish which nodules have high clinical suspicion for malignancy. Existing clinical guidelines do not apply to patients with signs and symptoms related to the lesion and with an increased baseline risk of lung cancer or metastasis. This paper highlights the vital role of pathohistological analysis and immunohistochemistry in the definitive diagnosis of such incidentally discovered lung nodules...

INTRODUCTION: Standard treatment for chronic lymphocytic leukemia (CLL) has experienced a dramatic change over the last few years. Until recently, CLL was treated using chemoimmunotherapy (CIT) with anti-CD20 monoclonal antibodies. Even though novel agents such as BTKi (Bruton Tyrosine Kinase inhibitor) and BCL2 inhibitors are the standard of care in most therapeutic settings, CIT still has its place in CLL treatment. Interestingly, little is known about its effects on the immune system of patients with CLL...
