Pleomorphic large cell lymphoma of the mediastinum

Definition

Pleomorphic large cell lymphoma of the mediastinum (PLCLM) is a B-cell non-Hodgkin lymphoma characterized by a neoplastic cell population that does not morphologically resemble lymphoid cells and rather simulates a sarcoma or anaplastic carcinoma.

Clinical Features

  • Incidence

    PLCLM is an uncommon neoplasm; in a series of 120 primary large cell lymphomas of the mediastinum collected over a period of 20 years, nine cases (7.5%) with morphologic features of PLCLM were identified (Suster and Moran 1996).

  • Age

    Adults are most commonly affected, with a mean age at presentation of 51 years (range, 30–65 years, in a series of nine cases).

  • Sex

    Males and females are almost equally represented in those diagnosed with PLCLM.

  • Site

    Clinically, patients present with a mediastinal mass, which commonly extends into the organs from its vicinity, such as mediastinal vessels, lungs, and cervical lymph nodes and soft tissue. The tumor is...
