#13915 Immunity

During heterosexual intercourse, seminal fluid containing HIV contacts vaginal squamous mucosa. Cells capture virions and transport the virus via lymphatics to regional lymph nodes. Within the germinal centers of these lymph nodes, the virions infect CD4+ lymphocytes and proliferate, causing CD4+ cell lysis with release of more virions, which are taken up on the surface of cells having Fc receptors, allowing continued infection by HIV of more CD4+ cells passing through the nodes. Which of the following types of cells is most likely to capture HIV on its surface via Fc receptors?

#13918 Head & Neck

A 25-year-old woman is concerned about a lump on the left side of her neck that has remained the same size for the past year.

Fine-needle aspiration of the mass is performed. Her physician is less than impressed by the pathology report, which notes, "Granular and keratinaceous cellular debris". Fortunately, she has saved her Robbins pathology textbook from medical school. She consults the head and neck chapter to arrive at a diagnosis, using the data from the report. Which of the following terms best describes this nodule?
