Systemic Lymphadenopathy as the Initial Presentation of Malignant Mesothelioma : A Report of Three Cases

Abstract EN

Systemic lymph node metastasis is a rare event in malignant mesothelioma.

It is even more exceptional when systemic lymph node metastasis is the initial clinical presentation.

Review of literature discloses only four cases in which metastatic lymphadenopathy was the only symptom of malignant mesothelioma.

We, herewith, report three cases where the initial diagnosis of malignant mesothelioma was made by biopsy of enlarged lymph nodes, which were the only clinical presentation.

Immunohistochemistry played a pivotal role in elucidating the mesothelial origin of their unusual systemic lymph node metastasis.
