Abstract True malignant mixed tumor (carcinosarcoma) of the salivary gland is an extremely rare tumor. By definition, it is composed of both malignant epithelial and malignant mesenchymal elements. The most common type of the former is squamous cell carcinoma or adenocarcinoma and the most common type of the latter is chondrosarcoma, followed in frequency by fibrosarcoma, leiomyosarcoma, osteosarcoma, and in rare instances liposarcoma. We report a case of true malignant mixed tumor of the parotid gland in association with a pleomorphic adenoma in a 47-year-old man that contained a very unusual type of malignant mesenchymal component, rhabdomyosarcoma. Cytologic and histologic features and immunohistochemical results are presented. In addition, the literature is reviewed, and the possible histogenesis and pathogenesis of malignant mixed tumor of the salivary gland are briefly discussed.

True malignant mixed tumor, or carcinosarcoma, of salivary gland origin is rare. Only 19 cases have been reported in the literature, and a review of cases seen at the University of Iowa over the last 60 years yielded only two. In one case the mesenchymal component of the tumor contained both osteosarcoma and chondrosarcoma. In the second case, the history and the histology suggest a progression from a carcinoma ex pleomorphic adenoma to a carcinosarcoma. These features are documented in this report and literature review.

Abstract: Salivary glands tumours are relatively rare to find. There is still no adequate data about the incidence of salivary gland tumours in Indonesia. The main objective of this research was to cognise the profile of salivary glands tumours patients in Prof. Dr. R.D. Kandou Central General Hospital Manado from July 2012 to June 2015. Methods used is descriptive retrospective. The results showed there are 37 patients with salivary gland(s) tumour(s). Male was 59,5% and female was 40,5%. By age groups found that <19 years for 2.7%, 19-30 years for 8,2%, 31-45 years for 21.6%, 46-60 years for 37,8%, >60 years for 29,7%. Based on the histopathological classification, pleomorphic adenoma for 56.8%, Whartin's tumor for 8.1%, myoepithelioma for 2,7%, basal cell adenoma for 2.7%, oncocytoma for 2.7%, cystadenoma for 5.4%, canalicular adenoma for 2.7%, mucoepidermoid carcinoma for 10.8%, adenocarcinoma for 5.4%, and acinic cell carcinoma for 2.7%. Based on the location of the tumours’ appearance, parotid gland for 83.8%, submandibular gland for 13.5%, minor salivary glands for 2.7%. Based by the incidences annually, first year for 21.6%, second year for 32.3%, and the third year for 46.1%.Conclusion: Males are more than females, most commonly found in the age group of 51-60 years, the most commonly benign tumour found is the pleomorphic adenoma, the most commonly found malign tumour is mucoepidermoid carcinoma, the most commonly location of the tumours’ appearance is the parotid gland. The salivary glands tumours continued to increase during the last three years.Suggestion: Still necessary to do further research about salivary glands tumours.Keywords: salivary glands tumours, age, gender, histopathology, location, profileAbstrak : Tumor kelenjar liur adalah tumor yang relatif sedikit dijumpai ditemukan. Belum ditemukan data yang lengkap tentang kejadian tumor kelenjar liur di Indonesia. Tujuan utama dari penelitian ini adalah untuk mengetahui profil penderita tumor kelenjar liur di RSUP Prof. Dr. R.D. Kandou Manado periode Juli 2012-Juni 2015. Metode penelitian yang digunakan adalah deskriptif retrospektif. Hasil penelitian memperlihatkan terdapat 37 penderita tumor kelenjar liur. Laki-laki sebanyak 59,5% dan perempuan 40,5%. Kelompok usia <16 tahun sebanyak 2,7%, 16-30 tahun sebanyak 8,1%, 31-45 tahun sebanyak 21,6%, 46-60 tahun sebanyak 37,8%, >60 tahun sebanyak 29,7%. Berdasarkan klasifikasi histopatologi jenis pleomorphic adenoma sebanyak 56,8%, Whartin’s tumor sebanyak 8,2%, myoepithelioma sebanyak 2,7%, basal cell adenoma sebanyak 2,7%, oncocytoma sebanyak 2,7%, cystadenoma sebanyak 5,4%, canalicular adenoma sebanyak 2,7%, mucoepidermoid carcinoma sebanyak 10,8%, adenocarcinoma sebanyak 5,4%, acinic cell carcinoma sebanyak 2,7%. Berdasarkan lokasi munculnya tumor, kelenjar parotis sebanyak 83,8%, kelenjar submandibula sebanyak 13,5%, kelenjar liur minor sebanyak 2,7%. Berdasarkan jumlah pertahunnya, tahun pertama sebanyak 21,6%, tahun kedua sebanyak 32,3%, dan tahun ketiga sebanyak 46,1%.Kesimpulan : Penderita laki-laki lebih banyak daripada perempuan, paling banyak ditemukan pada kelompok usia 46-60 tahun, tumor jinak yang paling banyak ditemukan adalah pleomorphic adenoma, tumor ganas yang paling banyak ditemukan adalah mucoepidermoid carcinoma, lokasi tersering munculnya tumor adalah kelenjar parotis. Penderita tumor kelenjar liur terus meningkat selama tiga tahun terakhir.Saran : Perlu dilakukan penelitian lebih lanjut tentang tumor kelenjar liurKata Kunci : tumor kelenjar liur, usia, jenis kelamin, histopatologi, lokasi, profil

Pleomorphic adenoma, though essentially benign can undergo malignant transformation. This is the case report of a 72 year old male with a giant tumor of parotid gland measuring 20.0X18.0X16.5cm & weighing 7 kg. Pleomorphic adenoma can rarely transform into carcinoma ex pleomorphic adenoma over time as it enlarges; moreover, histologically, squamous cell carcinoma (SCC) is exceedingly rare. Patient developed the tumor for a period over 20 years & it caused withdrawal from social contact. The tumor gradually enlarged without any pain or other complication except for rapid growth & pain a year before. Postoperative facial function and local control of tumor was achieved. Despite Of having a cancer with significant extracapsular invasion, our patient did not present any metastatic focus. Besides morphological patterns, authors need to categorize invasive carcinoma ex pleomorphic adenoma according to its potentiality to metastasize. Various parameters which can predict malignant transformation in pleomorphic adenoma is also yet to be explored.J MEDICINE July 2015; 16 (2) : 118-121

Salivary gland neoplasms represent about 3% of head and neck tumors. The area most affected by tumors is parotid salivary gland (standing for about 80% of all cases). The most common type of the neoplasm is pleomorphic adenoma (which accounts for 80-90% of all diagnoses). One of the rare diagnoses in this region comprises synovial sarcoma, as it mainly occurs in lower extremities. In head and neck region it accounts for about 3% of all diagnoses. About 20 cases have been described in this region, so far. The etiology of the disease remains unknown, but there are reports linking synovial sarcoma with the rearrangement in the gene responsible for chromosomal transcription t(X;18) (p11,q11).
