A primary malignant carcinoid tumour of right kidney in a 40 years old male patient is described. The neoplasm displayed histological features resembling the carcinoid tumours of gastrointestinal or respiratory tracts with trabecular pattern predominating. It revealed focal argyrophil positivity and was argentaffin negative. Despite an extensive search, no primary tumour else-where in the body was detected
