What's new on primary Hodgkin's lymphoma of the breast? A case report and review of the literature.

INTRODUCTION: According to literature, primary Hodgkin's lymphomas of the breast represent one of the rarer entity in the primary breast lymphoma (PBL) scenario. This is the reason why these tumors are insidious in mammary oncology.

PRESENTATION OF THE CASE: We report a case of HL primitive breast in an elderly patient in whom radiology suspected an advanced breast cancer with ipsilateral axillary involvement and in which the fine-needle aspiration came back not significant.

DISCUSSION: Eighteen cases of primary Hodgkin's lymphoma of the breast has been described in Literature in a very large period of time: from 1928 to 2016. The nodular sclerosis type is the most frequent histological variant.

CONCLUSION: Their rarity together with the fact that radiological investigations are not significant for the purpose of an exact diagnosis, make these lesions extremely difficult to identify.
