Lymphoid hyperplasia is the rapid proliferation of normal lymphocytic cells that resemble lymph tissue which may occur with bacterial or viral infections.
[1] The growth is termed hyperplasia which may result in enlargement of various tissue including an organ, or cause a cutaneous lesion.
[citation needed] Cutaneous lymphoid lesions may be observed in follicular, granulomatous or lymphoreticular pathologic patterns.
It is caused by an abnormal proliferation of secondary follicles and occurs principally in the cortex without broaching the lymph node capsule.
Histological features include distention or engorgement of both subcapsular and intraparenchymal sinuses by benign histiocytes which may be hemophagocytic.
