We present a case of a salivary gland tumour in a 25-year-old woman with lymphadenopathy and a clinical suspicion of lymphoma. The patient had a history of rapidly enlarging mass near angle of jaw which was resected and sent for histopathological examination. A final diagnosis of acinic cell tumour with dedifferentiation was made by histomorphological and immunohistochemical studies. Acinic cell tumour can mimic any salivary neoplasm phenotypically because of its varied architectural patterns of presentation with varied cell types, hence called the harlequin of salivary gland. Acinic cell tumour with dedifferentiation is a rare aggressive variant and requires adjuvant radiotherapy for better prognosis, hence the need for accurate diagnosis and communication to the surgeon.

D018267	Carcinoma, Acinar Cell	A malignant tumor arising from secreting cells of a racemose gland, particularly the salivary glands. Racemose (Latin racemosus, full of clusters) refers, as does acinar (Latin acinus, grape), to small saclike dilatations in various glands. Acinar cell carcinomas are usually well differentiated and account for about 13% of the cancers arising in the parotid gland. Lymph node metastasis occurs in about 16% of cases. Local recurrences and distant metastases many years after treatment are common. This tumor appears in all age groups and is most common in women.
