The 2017 revision of WHO Classification of tumors of hematopoietic and lymphoid tissues contains separate chapters on the immunodeficiency-associated lymphoproliferative disorders. In this mini-review, the brief description of pathological, immunophenotypical and clinical features of lymphoid neoplasms associated with primary immune disorders, HIV infection, those arising in post-transplant setting and other lymphoproliferative disorders (excluding those induced by radiation) is given. The heterogeneous spectrum of these lymphoid malignancies is specified by the nature of those factors that are capable to induce immune suppression or chronic antigenic stimulation of immune system. Taking into account the full swing of SARS-CoV-2 pandemic and our ignorance of the ability of this virus to induce the sustained stimulation of immune system, we could not exclude the high risk of autoimmune diseases and lymphoid neoplasms in the long-term post-pandemic period. In this context, the role of angiotensin-converting enzyme 2  as well as some recently reported cell receptors for SARS-CoV-2 cell entry should be considered as far as some of them (CD147, CD26) could be tumor-associated antigens.
