Pleomorphic adenoma (PA) is the most common salivary gland neoplasm and, although mostly benign, recurrences, being called recurrent pleomorphic adenoma (RPA) and malignant transformation to carcinoma ex pleomorphic adenoma (CXPA), do occur. Recently, attention has been focused on molecular targeted cancer therapy in various tumors, including salivary gland tumors. The aim of this study was to investigate the role of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER-2) in PA, RPA, and CXPA. In total, 20 cases of PA, 18 of RPA, and 7 cases of CXPA were immunohistochemically studied for ER, PR, and HER-2. For evaluation of ER and PR, only nuclear expression and greater than 10% positive cells were regarded as cutoff criteria. HER-2 was evaluated semiquantitatively and graded from 0 to 3+. HER-2 amplification was assessed by chromogenic in situ hybridization (CISH). Tumors were negative for ER, PR, and HER-2 in all cases of PA and RPA. A case of CXPA showed moderate and complete membranous staining, and 6 cases were negative. HER-2 amplification was not observed in any case. In conclusion, the lack of ER, PR, and HER-2 expression in PA, RPA, and CXPA suggests that these proteins are not involved in progression, recurrence, or malignant transformation of PA.

A multiform adenoma is the most commonly diagnosed benign tumor of the salivary glands. In the majority of patients, surgical resection of the tumor with the adequate surrounding tissue of salivary gland allows for complete recovery. A small percentage of the cases is a recurring pleomorphic adenoma. Even more rarely the diagnosis of carcinoma ex pleomorphic adenoma is made. The study presents two clinical cases of the malignant transformation of pleomorphic adenoma into the myoepithelial carcinoma. The surgical treatment and additional radiotherapy were performed in both cases.

Objective: To present a case of carcinoma ex pleomorphic adenoma in the parapharyngeal space and discuss its management.   Methods: Design:            Case Report Setting:           Tertiary Government Teaching Hospital Subjects:         One   Results:  A 40-year-old male patient with dysphagia for three months and a left-sided mucosa-covered oropharyngeal mass was found to have a prestyloid parapharyngeal lesion on CT Scans. Fine Needle Aspiration Cytology (FNAC) revealed a pleomorphic adenoma. With a past history of parapharyngeal pleomorphic adenoma excised transorally three years before, the present mass was excised by mandibular swing approach. Post-operative recovery was uneventful, but the final histopathological report was carcinoma ex pleomorphic adenoma.   Conclusion: Malignant transformation should be suspected in recurrent salivary tumors in the parapharyngeal space. Provided there was truly no pre-existing malignant focus in the originally-excised tumor, and that early recurrence was not due to inadequate initial excision, this patient had a rare condition where the same tumor underwent malignant transformation within 3 years only. To the best of our knowledge, such an early transformation to malignancy of a minor salivary gland tumor of the parapharyngeal space has not been reported in the English literature.   Keywords: carcinoma ex pleomorphic adenoma, pleomorphic adenoma, carcinoma,  parapharyngeal space, malignant, transformation, minor salivary gland tumor,  mandibular swing

AimsThe aim of the study is to correlate p16Ink4a expression with the clinical courses of pleomorphic adenoma (PA), its malignant transformation (CaexPA) and treatment outcomes.MethodsRetrospective analysis (1998–2019) of 47 CaexPA, 148 PA and 22 normal salivary gland samples was performed. PAs were divided into two subsets: clinically ‘slow’ tumours characterised by stable size or slow growth; and ‘fast’ tumours with rapid growth rate.ResultsPositive p16Ink4a expression was found in 68 PA and 23 CaexPA, and borderline expression in 80 and 20, respectively. All 22 (100%) normal salivary gland samples presented with no p16Ink4a expression. Significant difference in p16Ink4a expression was observed between normal tissue, PA and CaexPA (χ2 (4)=172,19; p=0.0001). The PA clinical subgroups were also evaluated separately, revealing additional statistical relations: ‘fast’ PA and CaexPA differed significantly in p16Ink4a expression (χ2 (2)=8.06; p=0.01781) while ‘slow’ PA and CaexPA did not (χ2 (2)=3.09; p=0.2129). 3-year, 5-year and 10-year survival among p16Ink4a positive CaexPA patients was 100%, 90.56% and 60.37%, respectively, and in CaexPA patients with borderline p16Ink4a expression was 90.0%, 73.64% and 22.20%, respectively. Statistically significant difference between expression pattern and survival rate was observed (F Cox test – F (16, 24)=2.31; p=0.03075).ConclusionsOur study confirms no p16Ink4a expression in normal tissue, but reveals differences in expression between ‘fast’ and ‘slow’ PA. We suggest that p16Ink4a overexpression is connected to PA proliferation and subsequent malignant transformation to CaexPA. Borderline p16Ink4a staining correlates with worse prognosis of CaexPA.

Karsinoma payudara invasif (KPI) merupakan keganasan yang berasal dari epitel saluran kelenjar susu dan menginvasi jaringan sekitarnya. Pemeriksaan patologi anatomi biasanya menyertakan derajat keganasan (DKg) dan dilanjutkan dengan pemeriksaan imunohistokimia estrogen receptor (ER), progesterone receptor (PR) dan human epidermal growth factor receptor 2 (HER2) untuk menentukan terapi dan memperkirakan prognosis. Penelitian ini bertujuan untuk mengetahui hubungan status ER, PR, HER–2 dengan DKg pada KPI. Subjek penelitian yang digunakan adalah pasien KPI yang telah diperiksa DKg, status ER, PR dan HER–2 pada tahun 2014–2015 di RSUD Abdoel Moeloek Bandar Lampung. Hasil penelitian menunjukkan DKg low grade sebanyak 13 pasien (24,1%), high grade sebanyak 41 pasien (75,9%), status ER‒ sebanyak 32 pasien (50,3%), ER+ sebanyak 22 pasien (40,7%), PR‒ sebanyak 32 pasien (59,3%), PR+ sebanyak 22 (40,7%) dan HER2‒ sebanyak 33 pasien (61,1%), HER2+ sebanyak 21 pasien (38,9%). Hasil uji Chi‒Square antara ER dengan DKg nilai p=0,001, antara PR dengan DKg nilai p=0,002, antara HER2 dengan DKg nilai p=0,53. Simpulan, terdapat hubungan antara estrogen receptor dan progesterone receptor dengan derajat keganasan pada karsinoma duktal invasif.

AbstractThe presence of melanin pigment and melanocytic markers expression have been rarely reported in salivary gland tumors. Herein, two cases of carcinoma arising in pleomorphic adenoma of the parotid gland and showing diffuse expression of myoepithelial and melanocytic markers are described. The clinical-pathological clues useful in the differential diagnosis with melanoma are discussed. In addition, a review of the pertinent literature is also proposed, discussing the pathologic mechanisms potentially involved in this phenomenon.
