[Primary extra-lymph node localization of non-Hodgkin's lymphoma. Considerations on a clinical case].

The location on first diagnosis of a non-Hodgkin lymphoma (NH lymphoma) in the respiratory structures (bronchi, pleura, pulmonary parenchyma) is rather rare (2-4%) in the absence of mediastinic and/or hilar adenopathy. In any event diagnosis is extremely difficult, often impossible even with the aid of a properly conducted biopsy since the biopsy does not provide suitable material. The case is presented of a 72 year old woman with intermittent hyperpyrexia and multiple alveolar masses, the aetiology of which was only identified 8 months after the onset of the symptoms with the appearance of latero-cervical lymphadenopathy where biopsy revealed the presence of an N.H. lymphoma that was highly malignant but otherwise unspecificable.
