accumulation of immune cells in tissue causing inflammation
Lymphocytic infiltrate refers to the accumulation of lymphocytes, a type of white blood cell, in a particular tissue. This often occurs as part of the body's immune response to infection, inflammation, or autoimmune conditions, where the immune system mistakenly attacks healthy cells. In the context of hair and alopecia, lymphocytic infiltrate can be seen in conditions like alopecia areata, where these immune cells target hair follicles, leading to hair loss.
