While adenoid cystic carcinoma is a common malignancy to arise within the salivary glands (21.9%) (Kokemueller et al. in Int J Oral Maxillofac Surg 33:25-31, 2004), it is seldom encountered as a tracheal mass and represents < 1% of all lung cancers. Tracheal tumors are an uncommon cause of dyspnoea due to their relatively rare occurrence (Baydur and Gottlieb in JAMA 234:829-831, 1975). They pose considerable diagnostic challenge clinically as their symptoms mimics more commoner ailments like asthma and chronic bronchitis...

Immunoglobulin G4 related disease (IgG4-RD) is a fibro-inflammatory disease of unknown etiology, characterized by lesions in the form of tumors, elevated serum IgG4 levels, plasma cells with significant IgG4 infiltration, accompanied by phlebitis obliterans and fibrosis. This disease usually has multiorgan disease, including pancreas, biliary tract, salivary glands, peri orbital tissues, kidneys, lungs, lymph nodes and retro peritoneum. IgG4-RD mainly affects men with a predominance of age by young adults until old age...

Mammary analog secretory carcinoma is a primary salivary gland neoplasm with histologic, immunophenotypic, and molecular features identical to those of secretory carcinoma of the breast. Similar neoplasms have now been reported to occur in various nonmammary sites including the parotid gland, submandibular gland, sinuses, lip, skin, thyroid gland, and lung. We report, to our knowledge, the first example of a primary vulvar neoplasm with pathologic features identical to secretory carcinoma of the breast and an ETV6-NTRK3 fusion...

Antitumor necrosis factor therapies have revolutionized the treatment of some inflammatory diseases. However, the use of these agents is associated with the development of many paradoxical autoimmune diseases. Less well-recognized is the association with sarcoidosis. We report a 55-year-old female with long-standing ankylosing spondylitis who developed persistent dry cough and dyspnea while receiving etanercept therapy. High-resolution computed tomography scanning showed mediastinal lymphadenopathy and multiple nodules in both lung fields developed two months after the administration of etanercept...

Adenoid cystic carcinoma (ACC) is an infrequent cause of malignancy that accounts for 1% of all tumors of the oral and maxillofacial region. We present a 59-year-old woman with a past medical history of adenoid cystic carcinoma of the left salivary gland treated with radiation and thoracotomy due to lung metastasis. Years after the onset of diagnosis, she presented with nonspecific gastrointestinal symptoms. For this reason, an abdominal computed tomography (CT) scan was done, revealing a liver mass in the right lobe, involving segments eight and five, concerning for malignancy...

Carcinosarcoma (CS) is a rare tumor, consisting of both carcinomatous and sarcomatous components. In this paper, we present a case of CS arising from a pleomorphic adenoma (PA) of the submandibular gland. A 64-year-old Japanese man presented with a left submandibular mass that had developed for 20 years with complaints of pain for the last 3 months. Magnetic resonance imaging showed a lesion involving the left submandibular gland. The patient underwent total dissection of the left submandibular gland and left cervical lymph nodes...

IgG4-related disease (IgG4-RD) is a chronic and systemic disease that can involve multiple organs. The most commonly involved organs include the salivary glands, orbital adnexal structures, paranasal sinus, thyroid, lungs, breasts, aorta, pancreas, biliary ducts, kidneys, retroperitoneum, lymph nodes, prostate, pituitary, and endocranium. Due to increased disease research, several new site-specific nuances of IgG4-RD have been described. The authors have reviewed the recent literature and briefly summarize the infrequent organ involvement of IgG4-RD...

RATIONALE: Myoepithelial carcinoma mainly occurs in the salivary glands, but myoepithelial carcinoma of the lung is extremely rare neoplasm whose biological behavior and clinical course still remain to be fully elucidated. Although considered as low-grade carcinoma, these tumors have a high rate of recurrence or distant metastasis. PATIENT CONCERNS: To date there are only 11 cases of pulmonary myoepithelial carcinoma reported in the English literature. We report a case of a 24-year-old woman diagnosed with primary pulmonary myoepithelial carcinoma...

Extramarginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) is a non-Hodgkin lymphoma of low-grade malignancy. The most common localization is the stomach, and the common nongastric sites are salivary glands, the skin, orbits, the conjunctiva, the lung, breasts, upper airways, other gastrointestinal sites, and the liver. Primary hepatic MALT lymphoma is a rare disease and the diagnostic can be challenging. The clinical presentation is nonspecific and may range from no symptoms to end-stage liver disease...

REVIEW
Irene Defrancesco, Luca Arcaini
Extranodal marginal zone B-cell lymphomas (EMZLs) of the mucosa-associated lymphoid tissue (MALT) are indolent lymphomas which can present at any extranodal site. The most frequent localizations (other than stomach) are ocular adnexa, salivary gland, skin, lung and thyroid. Chronic inflammation and antigenic stimulation are a potential risk for the development of MALT lymphomas. While Helicobacter Pylori (HP) is known to be associated with gastric MALT lymphoma and antibiotic therapy is effective in the setting of HP-positive, other microorganisms (such as Chlamydophila Psittaci, Campylobacter Jejiuni, Borrelia Burgdoferi) have been implicated in the pathogenesis of non-gastric MALT lymphomas...

Hyalinizing clear cell carcinoma of the bronchial glands is a very rare tumor. Since only five reports describing six tumors have been published to date, only a little is known about specific histologic findings and clinical features. Because of its rarity, hyalinizing clear cell carcinoma has not been described in the latest WHO classification of pulmonary tumors yet. Here we present three cases of bronchial hyalinizing clear cell carcinomas, confirmed by both fluorescence in situ hybridization (FISH) and RT-PCR, focusing on histologic and immunohistochemical characteristics in a comparison with three cases of salivary gland origin...

Xanthomatous sialadenitis (XS) is rarely reported. Here we report XS in a case of HLA-B27-positive ankylosing spondylitis showing also anti-MAG-positive polyneuropathy with IgM-kappa dysimmunoglobulinemia/paraproteinemia, lung small cell carcinoma and buccal squamous cell carcinoma (SCC). The lesions were identified in submandibular and labial minor salivary glands of a neck dissection specimen (made during a buccal 1.7 cm large SCC resection procedure). The oral SCC was resected at 8 months after the diagnosis of the lung small cell carcinoma (with skull dome metastases, revealed by a superior cava syndrome) and at 2 months after radiotherapy...

Extraosseous Ewing's sarcoma/primitive neuroectodermal tumor (ES/PNET) is a rare but aggressive and malignant tumor, and has been reported in various sites such as the lungs, biliary tract, kidney, prostate, stomach, esophagus, oral cavity, salivary glands, urinary bladder, uterus, cervix, gonads, and vagina. However, the pancreas is considered to be an extremely uncommon site and only a handful of cases have been published to date. We present here another case of a pancreatic ES/PNET. Our case intensifies the importance to recognize this rare type of tumor in the pancreas as there is a broad spectrum of tumors with a similar morphology that includes sheets of small, round blue cells...

Clinical studies have revealed that some patients will develop glucose tolerance dysfunction after recovering from acute pancreatitis (AP), which indicated the importance of investigating the potential therapies for restoration of islet β cell function. Cytokeratin 5 (Krt5)-positive cells are considered to function as stem or progenitor cells in the regeneration of lung and salivary gland following injury. In the present study, AP was induced by six hourly intraperitoneal injections of 100 μg/kg cerulein for 4 consecutive days in adult mice, in order to determine the role of Krt5-positive cells in pancreatic regeneration, especially in the restoration of β cell function and the underlying mechanisms...

Salivary duct carcinoma (SDC) is an aggressive form of salivary gland tumor, and SDC patients tend to be older men, more commonly in advanced stage with a poorer prognosis. Although the cytological characteristics of SDC on fine-needle aspiration cytology have been well-described at the primary site, they have not been explored in metastasis. Here we reported a case of HER2/HER3-positive metastatic SDC in the lung and pleural effusion. The patient was a man in his 50s who had undergone extended total parotidectomy in 2008...
