[Relapsed Hodgkin lymphoma with only breast involvement: a rare case report].

Relapsed Hodgkin lymphoma with only breast involvement is rare. There is no specific clinical presentation. It can mimic another breast cancer or inflammatory disease. The histological profile is often misleading in the pauci-cellular forms where the inflammatory component predominates. We report a case of an 18-year-old female patient treated for mixed-cell Hodgkin lymphoma who was admitted 6 months after complete remission for a left breast inflammatory nodule. The first assessment showed breast abscess. As there was not a good outcome despite adapted antibiotic, more investigations were added and showed a relapsed Hodgkin lymphoma with only breast involvement. The patient is currently receiving a 4 therapeutic line regimen of chemotherapy. Breast Hodgkin lymphoma´s prognosis is poor in most cases reported in the literature. Therapeutic advances (targeted therapy) can improve patient outcomes.
