Abstract:
Primary or secondary non‑Hodgkin’s lymphomas of the pleura are well known. Although
secondary are more frequent to involve the pleura; primary pleural lymphomas [PPLs] are
relatively rare in occurrence. Two types are discussed in literature: Primary effusion lymphoma
in patients with human immunodeficiency virus (HIV) infection and pyothorax associated
lymphoma. Primary pleural lymphoma can be also seen in immunocompetent patients with
no history of pyothorax or HIV infection. Primary T lymphoblastic lymphomas of pleura that
too occurring in children are quite rare. One should keep in mind the differential diagnosis
of PPL with unusual presentation and rare location in immunocompetent patients not only
in adults but also in children. Herewith we discuss two cases of T lymphoblastic lymphoma
in immunocompetent children who presented with pleural effusion and extensive thickening
of the pleura but were not associated with pyothorax
