Secretory carcinoma (SC) is a recently described salivary gland tumor reported in the fourth edition of World Health Organization classification of head and neck tumors. SC is characterized by strong S-100 protein, mammaglobin, and vimentin immunoexpression, and harbors a t(12;15)(p13;q25) translocation which leads to ETV6-NTRK3 fusion product. Histologically, SC displays a lobulated growth pattern and is often composed of microcystic, tubular, and solid structures with abundant eosinophilic homogenous or bubbly secretion. SC is generally recognized as low-grade malignancy with low-grade histopathologic features, and metastasis is relatively uncommon. In this case, we described a SC of hard palate that underwent high grade transformation and metastasis to the cervical lymph node in a 54-year-old patient. In addition, this case showed different histological findings between primary lesion and metastasis lesion. Therefore, the diagnosis was confirmed by the presence of ETV6 translocation. Here, we report a case that occurred SC with high-grade transformation in the palate, and a review of the relevant literature is also presented.

Background. Salivary gland secretory carcinoma is usually a low-grade neoplasm. However, high-grade transformation can occur and has important implications for clinical outcome. Methods. A patient presented with an enlarging buccal mass. Magnetic resonance imaging (MRI) showed a tumor with a biphasic appearance along the right parotid duct. Local excision and histopathologic examination confirmed the diagnosis of secretory carcinoma with high-grade transformation. ETV6-NTRK3 translocation and loss of CDKN2A/B were identified. Results. The patient subsequently presented with cough and dyspnea and was found to have pleural metastases. Carboplatin and paclitaxel exacerbated the symptoms. Crizotinib resulted in initial symptomatic and radiographic improvement; however, the patient soon succumbed to progressive intrathoracic disease. Conclusions. High-grade salivary gland secretory carcinoma can have a biphasic appearance on MRI. Diagnosis is confirmed by the histologic appearance and associated ETV6-NTRK3 fusion. Additional molecular genetic events leading to transformation are unknown; however, loss of CDKN2A/B may have contributed. Treatment with multimodal chemotherapy was of limited benefit.

<p>Mammary analogue secretary carcinoma are salivary gland tumors similar to secretary carcinoma of breast histologically. It usually affects adults with mean age group of 45 years. Clinically it is usually slow growing, low grade malignancy with favorable prognosis. We are reporting a case of 47 years old female presented with complaints of swelling behind left ear for last 7 years. It was slow growing, painless and persistent. On examination, 4 x 3 cm swelling was present just below left ear lobule. It was nontender, firm, irregular in shape with smooth surface with slight mobility and overlying skin pinchable. Fine needle aspiration cytology suggested benign tumor with cystic change. On contrast enhanced computed tomography scan, there was a lobulated hypodense lesion measuring 24×35×32 mm with internal septations and enhancement of wall in expected location of superficial as well as deep lobe of left parotid gland. Patient underwent left total conservative parotidectomy and histopathology came out to be secretory analogue mammary carcinoma. Subsequently she received post-operative radiotherapy. Patient is on regular follow up and disease free till date. Usually mammary analogue secretory carcinoma is a low-grade malignancy with good prognosis. Immunohistochemistry is confirmatory which shows positivity for S-100 protein and mammaglobin.</p>

Acinic cell carcinoma (AcCC) is a morphologically distinctive salivary gland malignancy often associated with chromosome rearrangements leading to overexpression of the NR4A3 transcription factor. However, little is known about how NR4A3 contributes to AcCC biology. Detailed RNA-sequencing of 21 archived AcCC samples revealed fusion reads arising from recurrent t(4;9), t(9;12), t(8;9) or t(2;4) chromosomal translocations, which positioned highly active enhancers adjacent to the promoter of the NR4A3 gene or the closely related NR4A2 gene, resulting in their aberrant overexpression. Transcriptome analyses revealed several distinct subgroups of AcCC tumors, including a subgroup that overexpressed both NR4A3 and MSANTD3. A poor survival subset of the tumors with high-grade transformation expressed NR4A3 and POMC as well as MYB, an oncogene that is the major driver in a different type of salivary gland tumor, adenoid cystic carcinoma. The combination of NR4A3 and MYB showed cooperativity in regulating a distinct set of genes. In addition, the ligand binding domain of NR4A3 directly bound the Myb DNA binding domain. Transformation assays indicated that, while overexpressed NR4A3 was sufficient to generate transformed colonies, the combination of NR4A3 plus Myb was more potent, leading to anchorage-independent growth and increased cellular invasiveness. The results confirm that NR4A3 and NR4A2 are the main driver genes of AcCC and suggest that concurrent overexpression of NR4A3 and MYB defines a subset of AcCC patients with high-grade transformation that display exceptionally poor outcome.

Mammary analogue secretory carcinoma is a rare salivary gland tumor that has a wide range of clinical presentation ranging from indolent, local and slowly growing tumors to a very aggressive, infiltrative and widely metastasizing forms. We report a case of an unfortunate patient whose tumor had a very quick ominous disease course with aggressive clinical and histological presentation. This case is the first case, to our knowledge, to be reported in the literature from Saudi Arabia of MASC with features of high grade transformation

The concept of dedifferentiation had previously been used in salivary gland carcinomas. Recently, the term “high-grade transformation” was introduced for adenoid cystic carcinoma, acinic cell carcinoma, epithelial-myoepithelial carcinoma, and polymorphous low-grade adenocarcinoma and may better reflect this phenomenon, although transformation into moderately differentiated adenocarcinoma (i.e., not “high grade”) has also been described. Among the immunohistochemical markers, Ki-67 seems to be the only one that can help distinguish between the conventional and transformed components; however, the combination of morphological criteria is still sovereign. The overexpression of p53 was observed in the transformed component in all tumor types studied, despite few cases having been demonstrated to carry mutations or deletions in TP53 gene. Genetic studies in salivary gland tumors with dedifferentiation/high-grade transformation are rare and deserve further investigation. This paper aims at providing an overview on the recent concepts in histopathological classification of salivary gland tumors, complemented by immunohistochemical and genetic findings.

Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor, with a limited number of published reports. Less than three hundred cases have been reported in the literature and only 18 of these cases have been reported in minor palatal salivary glands, though publication bias is likely a factor. We present a case of a 57-year-old male who was diagnosed with MASC tumor presenting in a minor salivary gland and briefly review the current literature. MASC has a variety of histological features and different range of clinical behaviors. The histopathological diagnosis of MASC can be difficult, and the immunohistochemical profile of MASC is still being updated. The gold standard for MASC diagnosis is cytogenetics, with the majority having a translocation t(12;15)(p133;q25). Presently, there is no conclusive evidence that MASC should be treated differently than any other low-grade malignant salivary gland tumors, though high-grade transformation has been described.

e18534 Background: The objective of our study was to evaluate the cytologically, morphologically and IGH detection of salivary gland (SGT), expression of HER2 and PD-L1, CPS and determine these associations with patient survival. Methods: The study included 59 patients with a confirmed diagnosis of salivary gland cancer (stage II-IVA) by cytology, morphology and IGH analyses. After that HER2, in tumor and tumor infiltrating immune cell PD-L1 expression (with CPS) was determined using IHC-testing. RET mRNA gene expression calculated with using real-time PCR. Results: Aspiration biopsies results: only in 22 (37.29%) cases the malignant tumor was cytologically confirmed. An IHC study showed the proportion of high-grade tumors significantly exceeded 3.82 times the proportion of low-grade tumors (p < 0.00001). Low grade SGT were 2 times more often recorded by morphological studies (p = 0.0172), high grade SGT - 1.37 times more often by IHC study (p = 0.0176). HER2 expression: (0) – 29(60.42%), (1+) – 11(22.92%), (2+) – 4(8.33%), (3+) – 4(8.33%). Median OS HER2-neg pp was 170.25±24.49 mo (95% CI 125.25-218.26), median OS of 8 pp (16.33%) with HER2 (2+,3+) was 41,00 mo (95%CI 4.50-72.00) (HR 0,07; 95% CI 0,01-0,38; p = 0.00715). Median PFS HER2-neg pp was 168.00 mo (95% CI 75.00-168.00), median PFS of 8 pp (16.33%) with HER2 (2+,3+) was 19,00 mo (95%CI 1.00-31.00) (HR 0,23; 95% CI 0.04-1.22; p = 0.01641). PD-L1 expression was: in tumor cells 0-90% in 11/49 pp (22.45%), in immune cells 0-50% in 26/49 pp (53.06%) (p = 0.0006). CPS was 0-100, median CPS 5 (95% CI 0.03-10.00). Median OS pp with CPS > 1 was 72.00 mo (95% CI 19.5-72.00); with CPS < 1 hasn’t yet been achieved (OR 0.26; 95% CI 0.09-0.75; p = 0.0124). RET mRNA expression was detected in 13 of 48 cases (27.08%). The expression level ranged from 0 to 0.205. The median PFS in the RET mRNA-positive pp was 168.00 mo (95% CI 16.00-168.00) and tended to exceed the median TTP in the RET mRNA-naive patient group. Conclusions: The results suggest that the understanding the receptor status of salivary gland cancer can be effective prognostic factors.

Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor that shares the same histologic appearance and ETV6 gene (12p13) rearrangement as secretory carcinoma of the breast. Prior to its recognition, MASC cases were commonly labeled acinic cell carcinoma and adenocarcinoma, not otherwise specified. Despite distinctive histologic features, MASC may be difficult to distinguish from other salivary gland tumors, in particular zymogen-poor acinic cell carcinoma and low-grade salivary duct carcinoma. Although characteristic morphologic and immunohistochemical features form the basis of a diagnosis of MASC, the presence of an ETV6-NTRK3 gene fusion is confirmatory. Given its recent recognition the true prognostic import of MASC is not yet clearly defined.
