Primary soft tissue Non-Hodgkin lymphomas are very rare and account only for 0.1 % of the cases. Generally, Non-Hodgkin lymphomas of the soft tissue present as large subcutaneous masses without evidence of nodal or skin involvement. We describe four cases of primary Non-Hodgkin lymphomas of the soft tissue in patients infected with the human immunodeficiency virus. The most common site of involvement was the chest wall in all the patients; histopathological and immunophenotypic examination of the biopsy smears revealed two cases of plasmablastic lymphomas, one Burkitt and one diffuse large B-cell lymphoma. Non-Hodgkin lymphomas should be included in the differential diagnosis of soft tissue masses in human immunodeficiency virus - seropositive patients.
