Axillary lymphoma masquerading as inflammatory breast cancer

Primary non-Hodgkins lymphoma (NHL) of the breast, and its extranodal spread to the breast resulting from systemic lymphoma, are recognised albeit uncommon conditions. However, lymphoma involving the axilla, presenting with the clinical appearance of inflammatory breast carcinoma (IBC) without infiltration of breast dermal lymphatics has not been reported previously. As highlighted by the two cases presented here, this entity should be considered in the differential diagnosis of patients presenting with clinical IBC. The cases highlight the importance of careful histological analysis to distinguish IBC from NHL, since management strategies and prognosis are quite different.
