(a) Threadlike structure containing a sinus structure (S), mast cell (MC) and its granules (asterisks), monocyte (M), and eosinophil (E). (b) Lymphatic vessel containing mostly lymphocytes (L). Note that there is a difference in the major resident cells between the threadlike structure and the lymphatic vessel.
