Background: Relapsed/metastatic salivary gland carcinomas (SGCs) have a wide diversity of histologic subtypes associated with variable clinical aggressiveness and response to local and systemic therapies. We queried whether comprehensive genomic profiling could define the tumor subtypes and uncover clinically relevant genomic alterations, revealing new routes to targeted therapies for patients with relapsed and metastatic disease. Patients and methods: From a series of 85 686 clinical cases, DNA was extracted from 40 µm of formalin-fixed paraffin embedded (FFPE) sections for 623 consecutive SGC...

Salivary duct carcinoma (SDC) is an uncommon, aggressive malignant neoplasm histologically resembling high-grade mammary ductal carcinoma. SDC can arise de novo or ex pleomorphic adenoma. To clarify the correlation of biomarker immunoprofile with clinicopathological findings and clinical outcome of SDC, we conducted immunohistochemistry for EGFR, HER2, HER3, AR, CK5/6, p53, and Ki-67, along with HER2 fluorescence in situ hybridization in 151 SDCs. SDCs ex pleomorphic adenoma more commonly overexpressed EGFR, HER2, HER3, and Ki-67 than de novo SDCs (P = 0...

Accessory parotid gland (APG) is seen in around 21%-56% of individuals. Tumors of accessory parotid are uncommon with an incidence rate of 1%-8% of all parotid tumors. Ductal carcinoma of APG is rare, so no reported incidence was seen in the literature. However, salivary gland ductal carcinoma is reported to be 1% of all salivary gland neoplasms. We report here a case of salivary duct carcinoma of APG. Clinical presentation, investigation, and management are discussed. A 69-year-old female presented with a history of the left cheek progressive swelling of 6 years' duration...

A sialo-cutaneous fistula is a communication between the skin and a salivary gland or duct discharging saliva. Trauma and iatrogenic complications are the most common causes of this condition. Treatments include aspiration, compression, and the administration of systemic anticholinergics; however, their effects are transient and unsatisfactory in most cases. We had a case of a patient who developed an iatrogenic sialo-cutaneous fistula after wide excision of squamous cell carcinoma in the parotid region that was not treated with conventional management, but instead completely resolved with the injection of botulinum toxin...

Salivary Duct Carcinoma (SDC) is a distinctive and clinically aggressive adenocarcinoma of salivary origin. It arises from the ductal epithelium, predominantly occurring in the major salivary glands, especially the parotid gland. Here, we report a case of an extensive salivary gland pathology involving the right side of face, possibly arising from the parotid gland in a 25-year-old male patient. On routine histopathology, the tumour mass revealed a papillary pattern of neoplastic ductal epithelial cells showing comedo-like-central necrosis...

BACKGROUND: Primary ductal adenocarcinomas of the lacrimal gland are very rare. This neoplasm shares some histological and immunohistochemical similarities with salivary duct carcinoma. CASE PRESENTATION: Here, we present a case of a 55-year-old Moroccan man with lacrimal gland adenocarcinoma. He underwent orbital exenteration with lymph nodes dissection and ipsilateral parotidectomy. After surgery, he was lost to follow-up and died 13 months later. CONCLUSIONS: Lacrimal gland tumors are rare but highly aggressive salivary gland tumors...

Salivary duct carcinoma is a rare malignancy associated with hormone receptor and human epidermal growth factor receptor 2 (HER2) overexpression. Local surgical control is the cornerstone of therapy, but a subset of patients develops metastatic disease portending a poor prognosis and limited management options. Intracranial metastases are an uncommon manifestation and present a therapeutic challenge. We report the case of a 31-year-old male who presented with facial pain and swelling subsequently diagnosed with salivary duct carcinoma...

Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma (HMSC), originally known as HPV-related carcinoma with adenoid cystic carcinoma-like features, is a peculiar neoplasm that is restricted to the sinonasal tract, exhibits features of both a surface-derived and salivary gland carcinoma (particularly adenoid cystic carcinoma), and is associated with high-risk HPV. Given the limited number of published cases, the full clinicopathologic spectrum of this neoplasm is unclear. Here, we present an updated experience of 49 cases...

AIMS: PLAG1 gene rearrangement is the most common genetic abnormality in pleomorphic adenoma (PA), resulting in overexpression of PLAG1 protein. PA and carcinoma ex pleomorphic adenoma (CA ex-PA) can mimic various benign and malignant salivary gland tumors. The aims of this study are to evaluate the sensitivity and specificity of PLAG1 immunohistochemistry (IHC) in the differential diagnosis of PA and CA ex-PA and to compare the PLAG1 immunohistochemical results to PLAG1 gene abnormalities as detected by fluorescence in situ hybridization (FISH)...

With the advent of targeted therapies, expression of sex hormone receptors and HER-2 in salivary gland tumors (SGTs) is of clinical interest. Previous reports of estrogen (ER) and progesterone (PR) receptor expression have varied. Androgen receptor (AR) and HER-2 overexpression are frequently reported in salivary duct carcinoma (SDC), but have not been studied systematically in other SGTs. This study examines ER, PR, AR, and HER-2 expression in SGTs. Immunohistochemistry for ER, PR, AR, and HER-2 was performed on 254 SGTs (134 malignant)...

OBJECTIVES: PD-1/PD-L1 and CTLA-4 have been investigated and are thought to play an important role in tumor evasion. This study aimed to investigate expression patterns of immune-related molecules, and their clinical impacts in malignant salivary gland tumors. PATIENTS AND METHODS: We performed immunohistochemical staining for PD-L1, PD-L2, CTLA-4, PD-1, and CD8(+) tumor-infiltrating lymphocytes in 70 malignant salivary gland tumors. Protein expression was assessed by H-score by multiplying the staining intensity by the percentage of cells with positive staining...

BACKGROUND: Salivary duct carcinomas (SDCa) are rare highly aggressive malignancies. Most patients die from distant metastatic disease within three years of diagnosis. There are limited therapeutic options for disseminated disease. RESULTS: 11 cases showed androgen receptor expression and 6 cases showed HER2 amplification. 6 Somatic mutations with additional available targeted therapies were identified: EGFR (p.G721A: Gefitinib), PDGFRA (p.H845Y: Imatinib and Crenolanib), PIK3CA (p...

Salivary duct carcinoma is a highly aggressive disease with a poor prognosis. Surgical resection is currently the only curative treatment, as there is no effective systemic therapy for this malignancy. Recently, trastuzumab has been shown to exhibit therapeutic efficacy in the treatment of salivary duct carcinoma; similarly, molecularly targeted agents, such as cetuximab, are expected to be useful for salivary duct carcinoma treatment. We herein describe the case of a 56-year-old man diagnosed with salivary duct carcinoma in the left submandibular region, with ipsilateral multiple metastases to the neck lymph nodes...

We report a rare case of low-grade intraductal carcinoma with tumor-associated lymphoid proliferation (TALP) in the parotid gland of a 75-year-old woman. Grossly, the tumor was solid and cystic. Histologically, the tumor consisted of a papillary-cystic, micropapillary, or focally cribriform proliferations of epithelial cells with low-grade cytological atypia. The interspaces between the epithelial components were filled with prominent lymphoid stroma and lymphoid follicles, superficially mimicking Warthin tumor...

Malignant non-basaloid tumors that arise from basal cell adenoma (BCA) are extremely rare. The patient was a 72-year-old Japanese male, who had noticed swelling of the left parotid region 21 years ago. A superficial lobectomy was performed. About 60% of the tumor was made up of cribriform and trabecular tissue composed of basaloid cells, which exhibited mild atypia and nuclear expression of β-catenin. This portion of the tumor was considered to be a BCA. In the other part of the tumor, the proliferation of large eosinophilic atypical cells, most of which formed intraductal structures, was observed...

BACKGROUND: Few studies have examined whether the use of adjuvant treatment impacts survival for early stage high-grade salivary tumors. METHODS: A retrospective review of the SEER database between 1973 and 2012 was performed. Patients with high-grade major salivary gland tumors including salivary duct carcinoma, carcinoma ex-pleomorphic adenoma, high-grade mucoepidermoid carcinoma, or adenocarcinoma, NOS were identified. Only stage I-II tumors were included. The impact of radiation status on observed and relative survival was examined...
