title: Tumoural cysticercosis.
abstract: The unusual occurrence of very large cysticerci presenting as tumour-like lesions prompted this search of the pathology records of a south Indian hospital, to find similar cases. The maximum diameter of 187 consecutively diagnosed extraneural cysticerci, was recorded and those cases exceeding the mean by two standard deviations reviewed. Six biopsies showing cysticerci with a maximum diameter ranging from 4 to 11 cm, were identified, and hospital records and all pathological material available, were reexamined. The clinical differential diagnosis included benign and malignant tumours, hydatid cyst and haematoma. All the cysts were confirmed to be cysticerci, but species diagnosis was not possible by examining archival material. In an appropriate geographical setting, large cysticerci should form part of the differential diagnosis of cystic tumour-like lesions. An attemp can then be made, while the specimen is still fresh, to identify the species.
