  • Pleomorphic adenoma is the most common benign tumor in the parotid gland and a parotidectomy with preservation of the facial nerve is a widely accepted treatment. We experienced a case of huge pleomorphic adenoma arising in the parotid gland with suspicious skin invasion. This present case was 67-year-old male presenting huge parotid mass $(12{\times}7cm)$ that has been present for 30 years and this tumor showed rapid-growing nature recently. The overlying skin surface was ulcerated with serous discharge and tightly adherent to the mass. The risk of malignant transformation of a pleomorphic adenoma increases with the duration of disease. The preoperative tentative diagnosis was carcinoma ex pleomorphic adenoma in the parotid gland. The initial pathologic diagnosis of fine needle aspiration biopsy was unsatisfactory smear. After parotidectomy, the histologic examination revealed that the parotid tumor was benign pleomorphic adenoma. We present a case of huge pleomorphic adenoma with skin invasion in the parotid gland with review of literatures.

  • Pleomonhic adenoma, the most common of the benign salivary gland tumor, is called benign mixed tumor. The tumor was first described by Kaltschmied in 1725 and clinically systematized by Bilroth in 1859. Most pleomorphic adenoma arise in major salivary glands. However, their development in minor salivay glands of the oral cavity, pharynx, paranasal sinuses, and in skin and lacrimal glands is well known. The palate is the most common site of origin of pleomorphic adenoma in minor salivary gland. Recently the authors have experienced a case of the huge pleomorphic adenoma of the hard palate in a 70 years old woman. This is the report of a case with review of literature.

  • Pleomorphic adenoma is the most common tumor in the parotid gland and a parotidectomy with preservation of the facial nerve is a widely accepted treatment. With the advanced imaging methods such as CT scan or MRI and the developed surgical technique, the incidence of complications in parotid surgery declined considerably. However, when the tumor forms a huge mass after a prolonged period, surgeons tend to hesitate surgical treatment regarding the possibility of facial nerve injury and incomplete resection due to a malignant transformation of the tumor. And this is more likely when the huge tumor arised in the deep lobe of the parotid gland. We present a case of 39-year old man with a giant pleomorphic adenoma arising in the deep lobe of the parotid gland who was treated successfully by total parotidectomy without any complications. The size and weight of the tumor were 20x15x15cm and 1,100gm, respectively. In our experience, because pleomorphic adenoma is well encapsulated and not invasive to the adjacent tissue, even a giant pleomorphic adenoma arising in the deep lobe of the parotid gland can be treated by careful surgical resection with the preservation of the facial nerve.

  • Pleomorphic adenoma of the parotid gland typically presents as painless, mobile mass of long duration, and originate in the superficial lobe but, more rarely these tumors may involve the deep lobe of the parotid gland. The average size of a parotid neoplasm is 2 to 4 cm. The effective treatment of parotid pleomorphic adenoma is surgical excision. The simple excision or enucleation resulted in recurrence rate of 45% in benign tumor. Therefore, the superficial parotidectomy with identification and preservation of the facial nerve is now the most widely accepted surgery. We report a case of the huge pleomorphic adenoma of the left parotid gland in a 67-year-old man who complained the large mass, measured about $10\times7\times5$cm-sized, in front of the left ear and on the mandibular ascending ramus. The diagnosis was confirmed by the clinical examination, computed tomographic scan, fine needle aspiration, and incisional biopsy. Superficial parotidectomy including the tumor and preservation of the facial nerve using the modified Blair approach was performed. And satisfactory results have been obtained cosmetically and functionally.
