Erythema nodosum (EN) was diagnosed. Further clinical examination revealed hilar lymphadenopathy. A lymph node was removed for histological examination, and a centroblastic non-Hodgkin lymphoma was diagnosed. Remarkably, in this patient EN occurred before the haematological malignancy was detected. | lld:pubmed |
