Acinic cell carcinoma (ACC) is a rare type of tumor which accounts for only 1–3% of the salivary gland tumors. Majority of which occurs in the parotid gland. ACC can be misinterpreted as benign because of its low grade histology. Radiological imaging techniques have low sensitivity in detecting malignancy of parotid glands. Guided FNAC can prove to be reliable diagnostic modality that can help in differential diagnosis of salivary gland neoplasms. Aspirates from these tumors can be diagnostically challenging. The lesions that have to be considered in the differential diagnosis include a wide variety of nonneoplastic as well as neoplastic conditions and pose a serious diagnostic dilemma cytologically. Hence histopathological examination is the gold standard method of choice for diagnosing these tumors. Here we report a case of Acinic cell carcinoma of parotid gland which had cytological diagnostic dilemma and confirmed diagnosis following histopathology examination.

Abstract Dedifferentiated acinic cell carcinoma of the salivary gland is an uncommon variant of acinic cell carcinoma, characterized by the coexistence of both an usual low-grade acinic cell carcinoma and a high-grade dedifferentiated component, as well as by an accelerated clinical course. We describe a case of acinic cell carcinoma of the parotid gland in a 67-year-old woman, which recurred 4 times after surgery and radiotherapy. The recurrences consisted of residual foci of acinic cell carcinoma intermingled with a high-grade epithelial proliferation; the latter was focally constituted by cells with morphologic and immunohistochemical features of myoepithelium.

The objective of this study was to evaluate the clinical outcome of patients with acinic cell carcinomas of the parotid gland after elective neck dissection (END). A retrospective chart review was performed including 66 patients with acinic cell carcinoma of the parotid gland. Clinical parameters were retrieved and statistically analyzed regarding disease-free survival (DFS) and disease-specific survival (DSS). An END was done in 27 (40.9%) patients, and occult metastases were detected in 4 (14.8%) patients of whom three were low-grade carcinoma. Positive neck nodes were associated with significantly worse DSS (p = 0.05). Intermediate and high-grade carcinoma (HR 8.62; 95% confidence interval (CI): 1.69–44.01; p = 0.010), perineural invasion (HR 19.6; 95%CI: 0.01–0.37; p = 0.003) and lymphovascular invasion (HR 10.2; 95%CI: 0.02–0.59; p = 0.011) were worse prognostic factors for DFS. An END should be considered in patients with acinic cell carcinoma of the parotid gland due to (i) a notable rate of occult neck metastases in low-grade tumors and (ii) the worse DSS of patients with positive neck nodes.

Abstract We report the familial occurrence of acinic cell carcinoma involving the parotid gland, the first such report of which we are aware. The familial occurrence of any salivary gland neoplasm is rare. Several reports are present in the literature, including pleomorphic adenoma, Warthin tumor, carcinoma of the submandibular gland, and malignant lymphoepithelial lesion. We report the case of a 35-year-old man who underwent excision of a left parotid gland acinic cell carcinoma. Eight years later, his daughter presented at the age of 16 years with a nontender parotid gland mass that was excised and found also to be acinic cell carcinoma. The histologic features of both neoplasms were typical of acinic cell carcinoma. While this may represent a coincidental event, the possibility that this familial occurrence is a manifestation of common genetic or environmental risk cannot be excluded.

Proper Diagnosis

Acinic cell carcinoma (ACC) is a rare, low-grade malignant salivary gland neoplasm.Parotid gland is the most common location reaching up to 90% of cases. Papillarycystic variant (PCV) is a much more seldom subtype of ACC. Proper diagnosis ofACC-PCV is only made on histopathology examination. The presence of psammomabody in salivary gland lesions is infrequent finding that may be confused with otherbenign or malignant lesions. The present case describes ACC-PCV in a 31-year-oldSaudi male patient referred to King Abdulaziz University Hospital as post superficialparotidectomy which the patient underwent 3 months ago. This case emphasizesthe importance of distinguishing between neoplastic and non-neoplastic lesions withnumerous psammoma bodies.Key words: papillary cystic acinic cell carcinoma–psammoma body–histopathology–parotid gland.

Parotid Gland Tumors

Salivary gland tumors account for 3–6% of tumors of the head and neck. About 80% of salivary gland tumors occur in parotid glands. Oxidative stress (OS) is implicated in the origin, development, and whole-body effects of various tumors. There are no data on the occurrence of OS in the parotid gland tumors. The aim of this study was to ascertain if whole-body OS accompanies parotid gland tumors, based first of all on oxidative modifications of blood serum proteins and other markers of OS in the serum of the patients. The group studied included 17 patients with pleomorphic adenoma, 9 patients with Warthin’s tumor, 8 patients with acinic cell carcinoma, and 24 age-matched controls. We found increased concentration of interleukin 4 in patients with acinic cell carcinoma, decreased plasma thiols, increased AOPP concentration, and decreased FRAP of blood serum in all groups of the patients while protein oxidative modifications assessed fluorimetrically, protein carbonyls, protein nitration, malondialdehyde concentration, and serum ABTS⁎-scavenging capacity were unchanged. These data indicate the occurrence of OS in patients with parotid gland tumors and point to various sensitivities of OS markers.
