Here, wereport a rare case of primary malignant neuroendocrine tumour of pleura in a fifty-two-year-old, nonsmoker female whopresented with right-sided pleural effusion and ipsilateral, dull aching chest pain. Clinical presentations of inflammatory lesionslike tuberculous pleuritis and benign and malignant neoplasms of pleura are indistinguishable; hence, fluid cytology, pleural biopsy,and immunohistochemistry are necessary for exact tissue diagnosis of the tumours, which is mandatory for correct treatment andprognostic assessment
