Despite the modern diagnostic capabilities, which are improving every year, the issue of differential diagnosis of cutaneous lymphoid hyperplasia with lymphoproliferative disorders still persists. In a number of cases making the diagnosis is only possible on the basis of tissue diagnostics.

Our work demonstrates the most common versions of cutaneous T-cell lymphomas (Peripheral cutaneous T-cell lymphoma, mycosis fungoides, primary cutaneousanaplastic large cell lymphoma, subcutaneous panniculitis-like T-cell lymphoma, etc.) and cutaneouslymphoid hyperplasia (cutaneous pseudolymphoma, tattoo-associated cutaneous lymphoid hyperplasia, etc.), as well as criteria for their differential diagnosis.
