Abstract
Warthin's tumor is the second most common neoplasm of the parotid gland and consists of 2 components, including lymphoid stroma and glandular epithelium. Malignant transformation in this tumor is mostly seen in the lymphoid component; however, the carcinomatous transformation of the epithelial component is extremely rare. Cases of latter reported in the literature include squamous cell carcinoma, adenocarcinoma, mucoepidermoid carcinoma, oncocytic carcinoma, Merkel cell carcinoma, and undifferentiated carcinoma. We describe an extremely rare case of salivary duct carcinoma arising in a Warthin tumor in a 64-year-old male. Patient presented with an enlarging left parotid mass, biopsy of which showed salivary duct carcinoma. He subsequently underwent left parotidectomy along with left level II-IV lymph node dissection. Histology revealed both in situ as well as invasive salivary duct carcinoma arising from Warthin tumor. Immunohistochemistry showed tumor cells positive for CK7, AR, and GATA3, while p63 highlighted the myoepithelial cell layer in the in situ component. Her2 was 2+ by immunohistochemistry. In addition, PD-L1 IHC revealed positive expression with a combined positive score of 20%.

Abstract
Sialoscintigraphy has been used in nuclear imaging for almost sixty years. It allows functional assessment and quantification of all large salivary glands. Physiological function of the salivary glands is essential for the preservation of the oral mucosa, the sense of taste and dental health. Impaired salivary gland function may lead to reduced or even absent salivation resulting in various complaints such as loss of taste reducing quality of life. During the recent years clinical relevance of assessment of salivary gland function has been rising. As novel radiopharmaceuticals such as 225Ac-PSMA or 177Lu-PSMA may cause damage to the salivary glands in a subset of patients, reliable methods for quantification of salivary gland function are vital for therapy planning and follow-up. Standardized protocols for the implementation and interpretation of this procedure are necessary to achieve comparable results from individual theranostic centers and to facilitate multicenter trials. Sialocintigraphy is also of clinical relevance for immunooncology. Treatments with checkpoint inhibitors such as Ipilimumab or Nivulomab frequently cause autoimmune disorders affecting the salivary glands that may lead to reduced production of saliva and finally loss of taste. Therefore, standardized procedure protocols for sialoscintigraphy are also important for general oncology.Here we suggest a protocol for sialoscintigraphy that may be used as standard in centers for theranostics or immunooncology and discuss the potential future role of this traditional procedure.

Incidence of Non-Salivary Gland Neoplasms in Patients with Warthin Tumor: A Study of 73 Cases. Head Neck Pathol 2019; 14:412-418.

Abstract
Warthin tumor is the second most common benign parotid neoplasm. Its association with non-salivary gland neoplasms has been sporadically reported. We reviewed clinical records of Warthin tumor diagnosed on aspiration cytology and surgical pathology to determine if there is any association with other extra-salivary gland malignant neoplasms. Computer search was made for all cases of Warthin tumor diagnosed in the parotid gland by aspiration cytology and surgical pathology at our institution between January 2007 and August 2016. Clinical records of all cases were reviewed for any associated malignant neoplasms and any surgical follow up. All available cytology and histologic material was reviewed. Seventy-three patients (mean 66.9, M:F 1.1:1, age range 43 to 87 years) with Warthin tumor were identified. 45 (62%) were diagnosed on aspiration cytology only, 19 (26%) had cytologic diagnosis as well as concordant surgical follow up, and 9 (12%) were diagnosed based on surgical pathology only. Average age for patients with and without secondary malignancy was 70.5-years, and 63.4-years, respectively (p < 0.05). Average pack years for patients with and without secondary malignancy was 45.4, and 39.8, respectively (p > 0.05). Twenty-seven (37.0%) patients harbored a malignant neoplasm. Association of extra salivary gland malignant neoplasms in 37.0% of our cases suggest that the prevalence of secondary non-salivary neoplasms in patients harboring Warthin tumor might have been underestimated. Squamous cell carcinoma was the most commonly associated non-salivary malignant neoplasm. The association of Warthin tumor with smoking plays an important role in this increased rate of malignancy, and this is supported by the fact that smoking is highly associated with head and neck and lung cancers.

Abstract
Mucoepidermoid carcinoma (MEC), an extremely rare tumor, arises from the epithelial component of preexisting parotid Warthin tumors (WT). Among the 309 cases of surgically resected WTs in Chinese PLA General Hospital and Beijing Shijitan Hospital of Capital Medical University, 5 cases (1.6%) fulfilled the criteria for MECs transformed from WTs. Clinicopathological characteristics of MECs was demonstrated in order to avoid misdiagnosis of this rare type of tumor. All the 5 patients, 3 males and 2 females, presented painless masses in the parotid gland. MECs were located inside or at the edge of WTs, with an obvious transitional zone between WT and MEC. Basal cells of WTs and epidermoid cells of MECs were strongly positive for cytokeratin CK5/6, CK34βE12, and P63; whereas negative for CK7, CK20, and CEA. Mucous cells of MECs were positive for CK7, CEA, as well as periodic acid-Schiff (PAS), whereas negative for CK5/6, CK34βE12, CK20, and P63. MECs patients were followed up for 25–69 months after surgery, presenting no evidence of recurrence or metastasis. Collectively, MECs arising from WT is very rare. The pathological diagnosis was based on histological morphology, especially the transitional zone between WT and MEC.

Abstract
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.

Abstract
Carcinomas arising in or from the epithelial component of preexisting parotid Warthin tumors (WTs) are rare; the other histologic types of carcinoma found to arise from WTs are adenocarcinoma not otherwise specified, undifferentiated, mucoepidermoid, squamous cell, and oncocytic. The aim of this study is to describe the clinicopathologic features of a distinct salivary gland neoplasm, previously undescribed, with a striated duct phenotype arising from WT. We have designated this neoplasm "Warthin adenocarcinoma" (WA). In this retrospective study, we searched the surgical pathology files of the Department of Pathology at The University of Texas M.D. Anderson Cancer Center for cases of malignant WT and salivary adenocarcinoma not otherwise specified diagnosed from January 1, 1985, through December 31, 2006, and evaluated patients' medical records and pathologic material. We obtained tissue sections and immunohistochemically stained them with antibodies against p63; Bcl-2; cytokeratin (CK)903, CK7, CK14, and CK18; antimitochondrial antibody (AMA); smooth muscle actin; calponin; S-100; and Ki-67. We identified 2 cases of WA; both patients were women, 44 and 60 years of age, with 4.0- and 4.5-cm tumors in the left parotid gland. Histologically, the tumors were composed of bilayered duct-like structures: The inner layer was formed by a single row of columnar oxyphilic cells expressing CK7, CK14, CK18, and AMA. The outer layer was composed of multiple layers of small round dark cells with scanty cytoplasm that expressed p63, Bcl-2, and CK903 and were focally positive for AMA and negative for myoepithelial markers. The Ki-67 proliferative indices were 20%; and 25%. A residual WT with transition to carcinoma was identified in both cases. Treatment had consisted of total parotidectomy with postoperative irradiation. Patients were free of disease 1 and 3 years after treatment. Warthin adenocarcinoma is a unique salivary gland carcinoma representing the malignant epithelial counterpart of WT. The identification of additional cases would help to better elucidate the line of differentiation of the tumor and further define its natural history.
