Neuroendocrine tumours occur at various sites in the human body. They are considered as one of the close differentials for many tumours. Various benign and malignant tumours undergo neuroendocrine differentiation. Its incidence is slightly increasing due to advanced imaging modalities. Although rare, they can be seen in breast, gallbladder and skin.
The aim of the study is to study the spectrum of neuroendocrine tumours from various sites, their clinical presentation, histomorphological features with immunohistochemistry and review of literature.
MATERIALS AND METHODS
This is a retrospective study for a period of 3 years (June 2013-June 2016). Surgical resection specimens were included in the study. Out of the total specimens received, 24 cases were of neuroendocrine tumours. Differential diagnosis of small round cell tumours also was considered and a panel of immunohistochemical markers were included to rule out them. Biopsy specimens were excluded from the study.
Out of the 24 cases, 18 cases were benign lesions. 6 cases were malignant lesions. Female preponderance was noted. Peak incidence was seen in 20-30 years of age group.
Neuroendocrine tumours can occur anywhere in the body and it should be considered in one of the differential diagnosis. Diagnosis must be accurately made.
