This case study highlights an aggressive primary gastric lymphoma of the MALT subtype presenting as pleural effusion. Lymphoproliferative disorders (LPD) are crucial considerations for unexplained pleural effusions.
Area of Science:
- Oncology
- Pulmonology
- Gastroenterology
Background:
- Lymphoproliferative disorders (LPD) can manifest with diverse clinical presentations.
- Primary gastric lymphoma of the MALT subtype is a specific type of non-Hodgkin lymphoma.
Observation:
- An 86-year-old female presented with pleural effusion, later diagnosed as aggressive primary gastric MALT lymphoma.
- Helicobacter pylori infection, a common risk factor, was notably absent in this case.
- The disease was disseminated at diagnosis and showed resistance to multiple treatments.
Findings:
- This case underscores the aggressive nature and uncommon presentation of gastric MALT lymphoma.
- The lack of Helicobacter pylori and treatment resistance represent unique aspects of this case.
- Pleuro-pulmonary involvement can be a primary manifestation of gastric lymphoma.
Implications:
- Lymphoproliferative disorders should be considered in the differential diagnosis of idiopathic pleural effusions.
- Further research into rare presentations and treatment-resistant gastric MALT lymphomas is warranted.
- This case emphasizes the importance of a comprehensive diagnostic approach for complex pulmonary presentations.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
