What is lymphocytic infiltration?

Lymphocytic infiltration refers to the accumulation of lymphocytes, a type of white blood cell, in a tissue or organ. This process often occurs in response to infection, inflammation, or autoimmune diseases, where the immune system mistakenly attacks healthy tissues. The presence of lymphocytic infiltration can be indicative of various conditions, such as chronic inflammatory diseases or certain types of cancer. It is typically assessed through histopathological examination of tissue samples.
