Clinicopathological characteristics and outcomes of 23 patients with secretory carcinoma of major salivary glands. Sci Rep 2021; 11:22639. [PMID: 34811395 PMCID: PMC8609010 DOI: 10.1038/s41598-021-01970-4] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Accepted: 11/08/2021] [Indexed: 02/06/2023] Open
Abstract
This retrospective study investigated the clinicopathological characteristics of secretory carcinoma of salivary glands (SCSG) in 23 patients with histopathologically confirmed SCSG between January 2010 and December 2020. In total, 13 males and 10 females (ratio, 1.3:1) aged 10 − 69 years (median, 45 years) were enrolled in this study; the average disease duration was 2.44 years (0.25–20 years). Twenty-one patients (91.3%) had SCSG in the parotid gland, and two (8.7%) in the submandibular gland. All patients had single nodules of diameters 0.8–4.8 cm (average 2.6 cm); five with lymph node metastases, and two with distant metastases. Immunohistochemically, tumors stained positive for S-100, mammaglobin, CK7, GATA3 and pan-Trk, and negative for DOG1, P63, and calponin, with Ki-67 positivity from 1 to 50%. ETV6 gene rearrangement was confirmed in 15 patients. All patients underwent oncological resection, four had radioactive particles implanted postoperatively, one received chemotherapy, and seven underwent chemoradiotherapy. Six patients had regional recurrences, two distant metastases, and one died before the last follow-up. SCSGs are typically indolent, with a low locoregional recurrence rate and excellent survival. Prognosis is correlated to clinical stage, pathological grade, and surgical procedures.

Vasanthi V, Ramadoss R. Secretory carcinoma of salivary gland - A systematic review of pediatric case reports and case series. J Oral Maxillofac Pathol 2021; 25:327-331. [PMID: 34703129 PMCID: PMC8491356 DOI: 10.4103/0973-029x.325236] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 01/28/2021] [Accepted: 05/18/2021] [Indexed: 11/12/2022] Open
Abstract
Aim: Mammary analog secretory carcinoma (MASC) is a new pathological entity of salivary gland origin recognized as Secretory Carcinoma (SC) in the WHO 2017 classification. Pediatric cases of MASC were reviewed systematically from 2010 to 2019. Materials and Methods: Databases were searched from 2010 to 2019 for pediatric case reports and case series, excluding retrospective studies. A total of 12 manuscripts were reviewed for clinical, histological and immunohistochemical findings. Results: A total of 13 pediatric cases (11 case reports and 1 case series of 2 cases) of MASC in pediatric patients were found. The youngest reported age was 5 years. The common site was parotid gland usually presenting as a slowly growing firm, painless mass. Conclusion: MASC should be considered in the differential diagnosis of salivary gland tumors in pediatric population, especially from parotid gland. Extended research on such recent entities with more inputs from new cases reported in literature may outstretch the possibilities of therapeutic fusion inhibition in future.

Mammary analogue secretory carcinoma of a salivary gland of the hard palate with contralateral cervical lymph node metastases: A case report. Mol Clin Oncol 2021; 15:226. [PMID: 34650798 PMCID: PMC8506652 DOI: 10.3892/mco.2021.2389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Accepted: 06/01/2021] [Indexed: 11/30/2022] Open
Abstract
Mammary analogue secretory carcinoma (MASC) is a rare malignant tumour of the salivary glands, with only few cases reported in the literature to date. Initial preoperative staging is crucial for all patients with an oral malignancy to visualize the tumour, detect lymph node or distant metastases and plan therapeutic interventions. In the case presented herein, radiological imaging revealed a tumour of the right hard palate with suspected positive contralateral lymph nodes. Therefore, local tumour resection comprising hemimaxillectomy and bilateral neck dissection was performed. The diagnosis of MASC was finally based on characteristic histopathological and immunohistochemical findings, such as S100 protein and mammaglobin positivity. The diagnosis of MASC may be challenging, as such findings lack specificity. To confirm the diagnosis, molecular genetic examinations may be performed to detect a highly specific ETV6-NTRK3 fusion gene. Depending on the results of these examinations, surgery, alone or combined with adjuvant radiation or chemoradiation, is the recommended approach. In summary, MASC should be treated similarly to other low-grade salivary gland tumours, such as acinic cell carcinoma, as they exhibit biological and histopathological similarities.

Radiological features of head and neck mammary analogue secretory carcinoma: 11 new cases with a systematic review of 29 cases reported in 28 publications. Neuroradiology 2021; 63:1901-1911. [PMID: 34427706 DOI: 10.1007/s00234-021-02796-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 08/17/2021] [Indexed: 12/29/2022]
Abstract
PURPOSE This retrospective study aimed to investigate the radiological features of head and neck mammary analogue secretory carcinoma (MASC) and systematically review previous publications and 11 new cases. METHODS We included patients with pathologically proven MASCs with preoperative CT or MRI images, including 11 patients from our hospital and 29 patients from 28 publications extracted after screening 645 abstracts. Two board-certified radiologists reviewed and evaluated all radiological images. The frequency of metastasis during the follow-up period in tumors with well- and ill-defined margins was compared using a Fisher's exact test. RESULTS The median age at diagnosis was 52.5 years (range, 7-78 years; 20 males). Of the 40 patients, those in their 50 s were the most common (10/40, 25.0%), and the main tumor site was the parotid gland (27/40, 42.5%). Characteristic radiological features included high intensity on T1WI in the cystic components and tumors frequently showed "papillary and cystic," which showed a projection into the cystic components, or "non-papillary and cystic" morphology, which did not show projection of the solid components. Tumor metastasis was found in 10/35 patients (28.6%) during the follow-up period, with a significant difference in frequency between the tumors with well- and ill-defined margin (well-defined (4/26) vs. ill-defined (6/9); P = 0.0074). CONCLUSION MASCs are newly recognized malignant tumors. Characteristic T1WI high intensity on MRI and predominant cystic morphology may reflect its unique histological profile. Ill-defined tumor margin status was related to frequent metastasis. Awareness of these characteristic radiological features can assist radiologists in better detection of this novel entity.

Abstract
Secretory carcinoma (SC) is an uncommon salivary gland neoplasm of the oral cavity that microscopically may mimic acinic cell carcinoma (ACC) and mucoepidermoid carcinoma (MEC). This study describes a series of SC in minor glands with a literature review. We performed a retrospective search for oral SC, within the archives of the University of Florida, Oral Pathology and Surgical Pathology Biopsy services from 2010 to 2018. A total of 10 SCs were identified in the oral and maxillofacial region, four of which were in the minor salivary glands. The demographic, clinical, histological, and molecular findings were aggregated for all 4 cases. Patient age varied from 30 to 60 years, with an average of 45 years. Two cases each were in female and male patients. Two cases presented on the labial mucosa, and one each on the hard and soft palate. Immunohistochemical (IHC) staining showed mammaglobin positivity in all cases, GATA3 positivity in two cases, S100 positivity in three cases, and SOX10 positivity in only one case. Fluorescence in situ hybridization demonstrated positivity for ETV6-NTRK3 fusion in 4 cases. Although oral SC is rare, pathologists should be aware of the histologic overlap between the SC and other salivary gland neoplasms such as ACC and MEC. A judicious application of IHC staining would aid in diagnosis. SC should be considered in the differential diagnosis for intraoral salivary gland tumors.

INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2019; 12:4338-4343. [PMID: 31933835 PMCID: PMC6949877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Accepted: 11/26/2019] [Indexed: 06/10/2023]
Abstract
Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumour notable for a balanced chromosomal translocation t(12;15)(p13;q25) that contributes to ETV6 gene rearrangements. It was first reported in 2010 by Skalova et al. with histological features resembling secretory carcinoma of the breast and was acknowledged and referred to as "secretory carcinoma" in the updated 2017 WHO classification. It is reported that MASC accounts for <0.3% of all salivary gland tumours, with a finite number of published reports on it. MASC has a range of histological features and clinical behaviours. The histopathological diagnosis of MASC can be difficult with current immunohistochemical methods. One case was located in the left palate, and 1 case was located in the soft palate. The maximum diameter of the tumour was 1.4~3.7 cm. CT demonstrated a mass that had not invaded into the palate bone, and the patients underwent palate neoplasm expanded ectomy without neck dissection or postoperative radiation therapy. Histopathological examination revealed that the tumour cells consisted of a mixed arrangement of microcystic, papillary-cystic, follicular, and solid lobular growth patterns. Eosinophilic cytoplasm and intraluminal or intracytoplasmic colloid-like secretions were observed. The final pathology confirmed the diagnosis of MASC with immunohistochemically neoplastic cells staining positive for S-100 and mammaglobin. The patients were asymptomatic at their 12-month follow up. More studies are needed to identify the typical behaviour of this tumour and establish the standard treatment regimen. This study aims to reinforce the awareness of this tumour by analysing its clinicopathologic features, immunophenotype, and diagnosis.
