Abstract
Introduction. Primary pulmonary salivary gland-type carcinomas are rare malignancies arising from minor salivary gland tissue in the lower respiratory tract. Given their rarity, constituting <1% of all primary lung malignancies, their epidemiological features and outcomes remain poorly documented. This study analyzed data from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database to identify primary pulmonary salivary gland carcinomas, including the most prevalent tumor types. Methods. All patients diagnosed with mucoepidermoid carcinoma, adenoid cystic carcinoma, and epithelial-myoepithelial carcinoma, with the lung designated as the primary site between 1975 and 2019, were subject to analysis. Overall and disease-specific survival were calculated using Kaplan-Meier curves and Cox proportional hazards models. Results. The study identified 323 mucoepidermoid carcinoma, 284 adenoid cystic carcinoma, and 6 epithelial-myoepithelial carcinoma diagnosed as pulmonary salivary gland-type carcinoma. An analysis of age distribution revealed a unimodal pattern for both mucoepidermoid carcinoma and adenoid cystic carcinoma, with most patients diagnosed after age 40. Most patients were Caucasians (77% for mucoepidermoid carcinoma and 83% for adenoid cystic carcinoma). Both disease-specific and overall survival were worse for patients diagnosed at the age of 60 years or above. Race or sex did not significantly impact patient survival. High-grade mucoepidermoid carcinoma demonstrated a significantly worse prognosis than low or intermediate-grade mucoepidermoid carcinoma. Conclusion. A comprehensive review of clinical and epidemiological features of pulmonary salivary gland-type carcinomas reveals that the age of diagnosis and tumor grade are the most significant factors in determining patient survival.

Abstract
Primary pulmonary salivary gland-type tumours are rare neoplasms that are thought to arise from seromucinous glands that are located in the submucosa of large airways. These neoplasms have clinical and pathologic features that are distinct from other pulmonary neoplasms. The majority of primary pulmonary salivary gland-type tumours are malignant, with the most common entities being mucoepidermoid carcinoma, adenoid cystic carcinoma, and epithelial-myoepithelial carcinoma. Less commonly seen are myoepithelial carcinoma, hyalinizing clear cell carcinoma, acinic cell carcinoma, secretory carcinoma, salivary duct carcinoma, intraductal carcinoma, and polymorphous adenocarcinoma. Benign salivary gland-type tumours of the lung include pleomorphic adenoma and sialadenoma papilliferum. Morphologic, immunophenotypic, and molecular features of these neoplasms are largely similar to salivary gland tumours elsewhere, and therefore the exclusion of metastatic disease requires clinical and radiologic correlation. However, the differential diagnostic considerations are different in the lung. The distinction of salivary gland-type tumours from their histologic mimics is important for both prognostication and treatment decisions. Overall, salivary gland type-tumours tend to have a more favourable outcome than other pulmonary carcinomas, although high-grade variants exist for many of these tumour types. Recent advances in our understanding of the spectrum of salivary gland-type tumours reported in the lung and their diversity of molecular and immunohistochemical features have helped to refine the classification of these tumours and have highlighted a few differences between salivary gland-type tumours of the lung and those primary to other sites.

Abstract
RATIONALE Salivary gland-type acinic cell carcinoma (ACC) is a low-grade malignancy. Primary ACC of the trachea and lungs is rare; here, we describe 1 such case. The histological morphology of tracheal ACC was similar to that of its salivary gland-associated equivalent. Because of its rarity, it is easily misdiagnosed as another type of tracheal or lung tumor. Microscopic analysis of pathological features and immunohistochemistry help diagnose primary ACC of the trachea and lungs. PATIENT CONCERNS A 33-year-old female complained of shortness of breath and hemoptysis for 2 years, and reported the symptoms to have aggravated over the last 4 months. The patient was admitted to our hospital for further treatment. Enhanced computed tomography revealed a soft tissue density nodule shadow in the trachea, which was approximately 1.3 × 1.2 cm in size. DIAGNOSES Based on the clinical information, morphological features, and immunohistochemistry, the pathological diagnosis was primary ACC of the trachea. INTERVENTION The tracheal lesion was resected with an electric snare, electrotomy, freezing, and an argon knife using a rigid bronchoscope. OUTCOMES The patient's postoperative course was uneventful. LESSONS It is important to prevent misdiagnosis of this type of tumor as another type of lung tumor. Morphological and immunohistochemical features can be useful in diagnosing primary ACC of the trachea and lungs.

Abstract
BACKGROUND Primary lung acinic cell carcinoma is very rare. Here we report a young female patient who suffered the largest primary lung acinic cell carcinoma with severe mediastinal deviation which has never been reported before. We also reviewed data and features of 20 previously reported cases of primary lung acinic cell carcinoma who underwent lobectomy. CASE PRESENTATION A 27-year-old female patient presented with recurrent coughing and hemoptysis for more than 10 years came to our hospital. A chest computed tomography (CT) showed a giant space-occupying lesion in the hilum of right lung. After a thorough and detailed preoperative examination, the patient then was performed a radical right pneumonectomy with mediastinal lymph node dissection. The size of the tumor was about 8.6 × 4.5 × 4.4 cm. The pathological results demonstrated a primary acinic cell carcinoma of right lung. The immunohistochemistry of the tumor showed AE1/AE3 (+), Ki-67 (2% +), CK7 (+), Vimentin (+), CK19 (+), α1-ACT (+), AB-PAS (+), S-100 (-), TTF-1 (-). The patient was discharged less than 2 weeks after the operation. So far, the patient has been followed-up for 2 years, and no evidence of tumor recurrence or metastasis was observed. CONCLUSIONS The primary acinic cell carcinoma of lung in this case is the biggest one ever reported and also the first case treated with radical right pneumonectomy. In addition, the patient had a very rare condition of severe mediastinal deviation at the same time. After surgical treatment, the patient recovered uneventfully and had stable disease without recurrence and metastasis after 2 years of follow-up. This case together with the reported case indicate that primary acinic cell carcinoma of lung is of low malignancy, the prognosis and therapy effect of surgical treatment are relatively satisfactory.

Abstract
Primary pulmonary acinic cell carcinoma (ACC) is rare. The clinicopathological features are not identical to that of classic ACC that leads to misdiagnosis. In this article, we summarized the clinicopathological features of 25 such cases, including 6 cases in this series and additional 19 cases in the literature. Pulmonary ACCs showed an overwhelming solid growth pattern. The neoplastic cells had eosinophilic granular and clear cytoplasm in most cases and displayed basophilic cytoplasm in only 4 cases. Intratumoral fibrous septa, mitotic figure, necrosis, and psammoma bodies were observed in some cases. Prominent nuclear atypia and perineural invasion might suggest high-grade transformation, metastasis, and recurrence. The tumor cells were strongly positive for CK8/18 and negative for TTF-1, p63, S-100, mammaglobin, MUC5b, MUC5ac, and DOG1. CK7 was exclusively positive for neoplastic cells with ductal differentiation. Of the 25 included cases, 10 cases were initially misdiagnosed. The tumor was prone to involve the right bronchus. The patient outcome was favorable. The accurate diagnosis of primary pulmonary ACC relies on comprehensive evaluation of histological and immunohistochemical features and realization of the difference from classic ACC.

Abstract
Abstract
Acinic cell adenocarcinoma is a malignant salivary gland neoplasm with a relatively low rate of lymphangitic spread to regional lymph nodes. Distant metastases are rare and their occurrence typically indicates an unfavorable outcome. We encountered an unusual example of acinic cell adenocarcinoma that initially presented in the lung, whereas the primary parotid carcinoma, despite extensive clinical evaluation, only became apparent 1 year after initial diagnosis. The histologic, immunohistochemical, and ultrastructural features of the tumor in the parotid gland and lung were similar. The tumor displayed an aggressive behavior resulting in death within 2 years of the initial presentation. This presentation is unique, showing that peripheral lung tumors of salivary gland type are likely to be metastatic, and careful clinical evaluation is warranted in establishing their primary site of origin.

Abstract
In the lung, acinic cell carcinoma (ACC) is a rare form of tumor. Reported herein is a unique bronchial gland-type tumor diagnosed as well-differentiated ACC that developed in the B9 bronchus of the left lung. Various immunohistochemical and histochemical staining partly satisfied the diagnosis of ACC. Moreover, this tumor contained various sizes of mucous cysts lined by columnar mucous cells, which produced abundant mucin positive for Alcian blue, which is usually present in mucoepidermoid carcinoma. Therefore, the present case is a unique tumor having a broad spectrum of cell differentiation from the terminal duct--acinar unit to the striated duct and excretory duct. This is the first case of unique bronchial gland-type tumor with mixed histological features of ACC and mucoepidermoid carcinoma.

Abstract
Salivary gland-type carcinomas of the lung are rare but well-known tumors. Among them, acinic cell carcinoma (ACC) is extremely rare and its cytological features have not been reported. We present a case of bronchial ACC and describe its cytological characteristics. The tumor occurred in a 58-yr-old man as a 15-mm polypoid lesion at the right middle lobar bronchus and filled its lumen. Transbronchial brush cytology and a biopsy failed to collect tumor cells but transbronchial fine-needle aspiration (FNA) cytology was successful. The smear obtained was richly cellular and a large number of thick-layered or monolayered sheet-like tumor cell clusters and dissociated tumor cells were observed. Cribriform globular spaces were common and a lobulated acinar structure was found focally. The tumor cells had a fine granular large polygonal cytoplasm and rather uniform round or ovoid nuclei. The nuclei were situated eccentrically or centrally and the nuclear/cytoplasmic ratio was consistently low. These cytological features were essentially similar to those of ACC of the head and neck region. The patient underwent a lobectomy and the tumor was resected completely. Transbronchial FNA cytology was useful for diagnosing bronchial ACC and differentiating it from other conventional and salivary gland type carcinomas.

Abstract
Salivary-type tumors occur in multiple sites in the human body, likely related to a basic structural homology between exocrine glands in these different anatomic areas. This paper reviews these salivary gland tumor types in breast tissue and lung. Salivary-type tumors of both breast and lung are relatively uncommon in comparison to their salivary gland counterparts. This may be attributable in part to lack of familiarity with these tumors in extra-salivary sites, and in part to histologic overlap with other primary and metastatic tumor types. Recognition of these entities is improving as the clinical and pathologic features are better delineated, and tumors are more accurately classified. Prediction of malignant behavior is not always possible in these unusual sites. In some instances, such as adenoid cystic carcinoma, behavior is known to differ considerably from that of analogous primary salivary gland tumors and in other instances there are simply too few reported cases to allow for adequate prognostication. In fact, more recent papers discuss the need to consider a spectrum encompassing benign and malignant lesions, in both breast and lung. Of course, some entities show clear-cut evidence of malignancy with documented potential for metastasis, others show bland features and well-reported benign behavior, and the less well-defined entities reside between these two extremes. The molecular pathology of salivary gland tumors has been reasonably well investigated in that location; however; there are few molecular studies devoted to salivary-type tumors of the breast and lung. This represents a potential area for future growth in further clarifying these tumors and their behavior.

Abstract
We report the case of a 30-year-old woman who presented with a subpleural mass in the lower lobe of the right lung, which was found incidentally on a routine chest radiograph. A wedge biopsy followed by lobectomy and lymph node staging revealed an acinic cell carcinoma with involvement of a hilar lymph node. The subcarinal and mediastinal lymph nodes were free of tumor. Perineural invasion was identified at the periphery of the tumor. There was no evidence of origin from salivary gland or involvement of any other organ. The patient was well 12 months postoperatively. To our knowledge, this is the second case report featuring lymph node metastasis in an acinic cell carcinoma of the lung and the first to demonstrate perineural invasion.

Abstract
This article provides a broad overview of tumors that can involve the tracheobronchial tree. For the most part, the clinical, radiographic, and endoscopic presentation of these rare tumors does not differ significantly from the more common tumors of the lung. Appropriate classification of many tracheobronchial tumors ultimately requires complete sampling and a thorough microscopic evaluation. The introduction of ancillary diagnostic techniques such as immunohistochemistry and molecular analysis will continue to refine tumor classification.
