Carcinoma arising from Warthin tumor is extremely rare. A 79-year-old man was admitted for a firm, well-defined, 5-cm left infra-auricular mass. Aspiration cytology showed many lymphohistiocytes and oncocytes in a proteinaceous background, compatible with Warthin tumor. A left superficial parotidectomy showed a solid mass around the cyst wall. The tumor cells of the solid area were arranged as infiltrative ducts with a few foci of malignant transformation. Virtual karyotyping disclosed a complex pattern of genetic aberrations with a focal amplification in 12q14-q21.2. This chromosomal region contains the MDM2 (murine double minute) gene, which regulates p53 inactivation. HER2 fluorescence in situ hybridization showed a focal amplification. Subsequently, the patient underwent total parotidectomy and ipsilateral neck dissection for a recurrence. To our knowledge, this is the first case of salivary duct carcinoma arising from Warthin tumor. The essential molecular pathway has not been reported, we presume an important role of MDM2 amplification- P53 inactivation.

A rare tumor of the female genital tract, most often the ovary, formerly considered to be derived from mesonephric rests. Two varieties are recognized: (1) clear cell carcinoma, so called because of its histologic resemblance to renal cell carcinoma, and now considered to be of muellerian duct derivation and (2) an embryonal tumor (called also ENDODERMAL SINUS TUMOR and yolk sac tumor), occurring chiefly in children. The latter variety may also arise in the testis. (Dorland, 27th ed)
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.

Any of the ducts which transport saliva. Salivary ducts include the parotid duct, the major and minor sublingual ducts, and the submandibular duct.
A carcinoma discovered by Dr. Margaret R. Lewis of the Wistar Institute in 1951. This tumor originated spontaneously as a carcinoma of the lung of a C57BL mouse. The tumor does not appear to be grossly hemorrhagic and the majority of the tumor tissue is a semifirm homogeneous mass. (From Cancer Chemother Rep 2 1972 Nov;(3)1:325) It is also called 3LL and LLC and is used as a transplantable malignancy.
A transplantable, poorly differentiated malignant tumor which appeared originally as a spontaneous breast carcinoma in a mouse. It grows in both solid and ascitic forms.
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
