pseu·do·lym·pho·ma

(sū'dō-lim-fō'mă),
A benign infiltration of lymphoid cells or histiocytes that microscopically resembles a malignant lymphoma.

pseudolymphoma

[-limfō′mə]
a benign disorder of lymphoid cells or histiocytes that produces clinical features of a malignant lymphoma.

pseudolymphoma

A form of lymphoid hyperplasia, which is characterised by relatively monotonous infiltrates of lymphocytes, and may be seen in breast, gastrointestinal tract, lung, mediastinum, orbit, salivary gland, skin, soft tissue, thyroid, etc. Pseudolymphomas occur in a younger population, and have been associated with collagen diseases, systemic lupus erythematosus, Sjögren syndrome, phenytoin therapy. They may present in those with concomitant lymphoma or in those who later develop lymphoma.
