BENIGN REACTIVE LYMPHOID HYPERPLASIA

Key Points

This disease constitutes a benign proliferation of lymphoid follicles that contain polymorphic lymphocytes that are immunohistochemically polyclonal.[50, 51] Benign reactive lymphoid hyperplasia (BRLH) occurs most commonly in the anterior superior orbit, with a predilection for the lacrimal gland (15%). The clinical course is indolent, with painless exophthalmos, globe displacement, and typically normal vision. A firm, rubbery mass is often palpable beneath the orbital rim, and there may be a pink subconjunctival “salmon-patch” infiltrate.
