  • Autoimmune Lymphoproliferative Syndrome Type 3

    A rare autoimmune disorder characterised by a loss of lymphocyte homeostasis; B-cell lymphocytosis; expansion of an unusual population of CD4/CD8-deficient T cells, which[medical-dictionary.thefreedictionary.com] Polyclonal B cell lymphocytosis with expansion of CD5 B cells was a characteristic finding.[unboundmedicine.com] T- and B-cell lymphocytosis.
