Symptoms of pulmonary pseudolymphoma?

summary

Pulmonary pseudolymphoma (PL), also known as nodular lymphoid hyperplasia, is a kind of bronchus associated lymphoid tissue, which is different from the true pulmonary lymph nodes in histology. It is generally considered to be a benign inflammatory lymphoproliferative lesion. The lesion is usually a single nodule and is limited to a single lobe. Today, let me talk about the symptoms of pulmonary pseudolymphoma?.

Symptoms of pulmonary pseudolymphoma?

First, a small number of patients had a history of pneumonia. Most patients had only mild cough and chest pain. It is usually found on chest X-ray. Generally, the course of disease is long, and there is no change in a few years after the diagnosis.

Second, pseudolymphoma is difficult to distinguish from low-grade malignant lymphoma, and it must be confirmed by auxiliary techniques such as immunophenotyping and gene rearrangement.

Third, it showed a single nodule or infiltration in the lung as localized consolidation, with clear margin and bronchial inflation sign, while hilar and mediastinal lymphadenopathy were rare; Lymph node enlargement often increases the possibility of malignant transformation of the disease. Pleural effusion is rarely seen on chest X-ray. Immunomarker assay showed polyclonal staining.

matters needing attention

It is a benign disease with satisfactory surgical results, but about half of the patients can develop into malignant lymphoma. Both chemotherapy and radiotherapy can make pulmonary pseudolymphoma develop into malignant lymphoma.
