Polymorphous low-grade adenocarcinoma is a rare salivary gland malignant tumor of low aggressiveness, commonly occurring in minor salivary glands. Its origin in major salivary glands is considered exceedingly rare. We report a case of polymorphous low grade adenocarcinoma arising from left parotid in a 21-yearold female patient.Journal of Pathology of Nepal (2012) Vol. 2, 331-334DOI: http://dx.doi.org/10.3126/jpn.v2i4.6890

Clinicopathological Study

AbstractThe major salivary glands are considered to rarely be the sites of primary terminal duct adenocarcinomas, a neoplasm with a considerable predilection for origin from intraoral minor salivary glands. We present a clinicopathological study of 22 terminal duct adenocarcinomas of the parotid gland, the largest single series to date. A comparison between the parotid neoplasms and over 200 minor salivary gland terminal duct adenocarcinomas indicates there is little difference in biological behaviour and confirms the low-grade quality of the carcinomas, regardless of site of origin.

Introduction. Although pleomorphic adenoma is the most common neoplasm of the salivary glands, this tumor most commonly involves the minor salivary glands of palatal and rarely occurs in cervical region.Case Report. A 21-year-old female referred to our clinic due to painless mass of right upper region of neck. After paraclinical and pathologic evaluation, it was diagnosed as cervical pleomorphic adenoma.Conclusion. Pleomorphic adenoma may be rarely involving the neck. Although the prognosis is good, the choice treatment is the complete resection of the tumor.

Background Hyalinizing clear cell carcinomas (HCCCs) are rare, low-grade, malignant tumors which most often arise from the minor salivary glands primarily in palate and tongue but can arise in any location with minor salivary glands including the nasopharynx. Methods A case report of primary nasopharyngeal HCCC is presented. Because of the rarity of this tumor and location, a literature search was conducted to determine the most common presenting symptoms, treatment strategies, and outcomes. Results A 48-year-old man underwent biopsy of a 4.5 cm mass of the right nasopharynx with pathology suggesting an intermediate grade mucoepidermoid carcinoma. After discussing management with the patient, an endoscopic resection was performed. Final pathology revealed an HCCC which was confirmed after negative Mastermind-like 2 (MAML2) and positive Ewing sarcoma breakpoint region 1 (ESWR1) gene rearrangements on fluorescence in situ hybridization (FISH) studies. Literature review of other nasopharyngeal HCCC cases shows diverse presentation and overall excellent prognosis through surgical and radiation therapy. Conclusion HCCCs are rare, low-grade malignant tumors of the minor salivary glands and can present as a nasopharyngeal mass. Presenting symptoms are diverse but frequently involve otologic and sinonasal disturbances. HCCC is an indolent tumor with an excellent prognostic outcome when treated appropriately with surgical resection and adjuvant radiotherapy.

Histopathologic Features

Non-neoplastic cysts of the salivary glands are uncommon and represent 2-5% of all salivary gland lesions. They are mainly mucoceles or salivary duct cysts. Unlike a mucocele, which is surrounded by granulation tissue, the salivary duct cyst is lined by epithelium. Salivary duct cysts are more common in the oral minor salivary glands and rarely occur in the major salivary glands, show a marked predilection for the superficial lobe of the parotid, and represent 10% of all salivary gland cysts. Neoplastic differentiation of the lining of the salivary duct cyst has been reported. We report a case of a salivary duct cyst of the left parotid gland, with a review of radiographic and histopathologic features.

Adenocarcinomas of salivary glands are encountered less frequently than adenoid cystic or mucoepidermoid carcinomas. They fall into two well-defined clinicopathologic groups: 1) those arising from intercalated ducts and 2) those from the excretory and interlobular ducts. The former, designated terminal duct adenocarcinomas, are low-grade malignancies found preponderantly in the oral cavity, especially the palate. The latter, designated salivary duct carcinomas, are high-grade neoplasms and arise almost exclusively in major salivary glands, especially the parotid gland.

Gland Tumour

The origin of a salivary gland tumour is attributed to cells at various levels of differentiation which present histologically as diverse tissues and cellular patterns. Mitochondria-rich, eosinophilic oncocytes are cells commonly encountered in salivary gland neoplasms. We report a case of mucoepidermoid carcinoma (MEC) in the palate of a 43-year-old female that exhibited a prominent oncocytic component. While the parotid and submandibular glands have been reported as predominant sites for oncocytic MEC (OMEC), the palate and minor salivary glands are rare sites for occurrence. Also, most of the reported cases of OMEC have been histologically of low-grade mucoepidermoid carcinoma with large cystic spaces and good prognosis. In this article, we discuss the differential diagnosis and diagnostic workup of an MEC presenting with oncocytes.

Abstract BACKGROUND. Primary malignant lymphomas of the salivary gland are rare, accounting for 2% of salivary gland tumors and 5% of all extranodal lymphomas. The clinical presentation is not particularly characteristic, a feature that usually leads to diagnostic and treatment delays. CASE REPORT. We report a case of a parotid gland triple-hit diffuse large B-cell (DLBCL) lymphoma associated with follicular lymphoma in a 76-year-old female patient with a unique personal history, which included a diagnosis of Sjogren Syndrome and exposure to a toxic working environment with pesticides. Diffuse large B-cell lymphomas are uncommon given the fact that most lymphoid malignancies are low-grade lymphomas, with MALT (mucosa associated lymphoid tissue) lymphomas being the most common. Triple-hit DLBCL are extremely rare and the diagnosis can be challenging. Parotidectomy, as the first step, must be followed by histopathology and immunohistochemistry for final diagnosis and treatment. CONCLUSION. This case highlights the fact that B-cell lymphoma in the salivary gland can be unrecognized due to unspecific symptoms and requires immunohistochemistry studies for confirmation. It is important to recognize triple-hit lymphoma due to its worse prognosis and differentiated treatment. Patients with Sjogren syndrome have additional risk factors for progression to lymphoma.

Salivary Gland Tumours

Abstract Basal cell adenocarcinoma is an unusual basaloid tumour that usually affects the parotid and very rarely involves the submandibular or minor salivary glands. It constitutes 1.6% of all salivary gland tumours and occurs as an asymptomatic freely mobile mass with occasional lymph node metastasis. Differentiation from benign salivary gland tumours like basal cell adenoma is accomplished by determining the depth of tumour invasion and patterns of growth or infiltration. Although it is categorised as a low-grade malignancy, it has a high propensity for recurrence. Surgical excision with a wide margin is the preferred course of treatment with radiotherapy being reserved only for tumours of the minor salivary glands with a diffuse pattern of infiltration. We present here a case of basal cell adenocarcinoma with a rare presentation in the minor salivary glands of the tongue which arose from a previously treated basal cell adenoma in the same site.
