Primary Pulmonary Anaplastic Large Cell Lymphoma: A Rare Malignancy and Rare Cause of the Luftsichel Sign

الملخص EN

Primary pulmonary lymphomas are rare with primary pulmonary non-Hodgkin lymphoma accounting for only 0.3% of primary lung neoplasms.

Of these, the large majority are made up of marginal zone B-cell lymphoma and diffuse large B-cell lymphoma.

We present a case of a very rare primary pulmonary anaplastic large cell lymphoma presenting as the luftsichel sign on chest radiograph.

Pertinent imaging and pathology findings are discussed.
