Lipomas are common benign soft tissue neoplasms but they are found rarely in the PAROTID GLAND.Surgical intervention in these tumors is challenging because of the proximity of the facial nerve, and thus meticulous surgical techniques are essential. The patient was a 12-year-old female presented with a large asymptomatic mass which had occupied the right facial area.She requested surgical excision for cosmetic reasons. The CT scan defined giant lipoma arising from the right PAROTID GLAND. The lipoma was successfully removed after dissecting and preserving of the facial nerve branches. The patient experienced an uneventful recovery, with and intact facial nerve function.Lipomas of PAROTID GLAND are extremely rare. The high- resolution CT scan provides a prefer method of preoperative diagnosis. Surgical management should be performed by experienced surgeon. Superficial PAROTIDectomy is unnecessary in selected cases of deep lobe lipomas because preservation of superficial lobe may contribute to better cosmetic results.

Approximately 3% of all head and neck neoplasms occur in PAROTID GLAND and less than 1% of these are oncocytic neoplasms. They are usually benign tumors and most commonly arise from the PAROTID GLAND. The world Health Organization histologic classification of salivary GLAND tumors divides PAROTID oncocytic neoplasms into three categories: Oncocytosis, oncocytoma, and oncocytic carcinoma. We report a case of oncocytoma in the PAROTID GLAND.

Introduction PAROTID GLAND squamous cell carcinoma is an uncommon aggressive neoplasm with poor prognosis. Aural polyps are usually the presenting features of chronic suppurative otitis media, tuberculous otitis media, and adenoma or carcinoma. The malignant aural polyp is very rare. PAROTID GLAND carcinoma masquerading as an aural polyp has rarely been described in the literature. Case Report: We report a case study of PAROTID squamous cell carcinoma in a 29-year-old male masquerading as an ear polyp. Conclusion: PAROTID GLAND primary squamous cell carcinoma is a rapidly advancing neoplasm which carries poor prognosis despite multimodality treatment. Diligent clinical and histopathological evaluation is imperative to discriminate this rare aggressive disease from the metastatic and other primary cancers of the PAROTID. A high index of suspicion is crucial in refractory aural polyps to arrive at early diagnosis.

Introduction: Schwannoma is an uncommon benign neoplasm which in is found in head and neck in 25-48% of the cases. This tumor arises from Schwann cells and nerve sheath and asymptomatic swelling is the chief complaint of this tumor. Although aspiration is performed for such cases, the nature of tumor can be defined only after histopathologic examination. In fact, Schwannoma diagnosis is difficult before the surgical procedure.Medical History: The case was a 24-year-old female who had a mass at the anterior of the left ear for three years. She did not have spontaneous pain. The lesion was mobile and painful in deep palpation. CT with contrast was performed for the patient which showed left PAROTID enlargement and a hypodense mass in the middle. Fine-needle aspiration biopsy (FNA) revealed pleomorphic adenoma. The patient underwent a superficial lobe PAROTIDectomy. Microscopic examination showed PAROTID schwannoma with cystic changes.Conclusion: PAROTID GLAND is an uncommon location for schwannoma. There are no pathognomonic visual findings for this lesion. Only 17.6% of the reported PAROTID schwannomas have been diagnosed before the surgical procedure. FNA is not a reliable procedure for tumor diagnosis, because in most of the cases it shows benign tumor of salivary GLAND i.e. pleomorphic adenoma. The nature of these tumors can be defined only after histopathologic examination. Since in histopathology of pleomorphic adenoma, myoepithelial cells were seen as schwannoma-like fusiform cells, immunohistochemistry was also performed to make sure of the diagnosis. In this method, CK and S100 markers in order to stain, which CK demonstrated negative result and S100 reported positive results, thus confirming the diagnosis of schwannoma.

Introduction: Sialolipoma is an extremely rare salivary GLAND tumor characterized by a well circumscribed mass composed of GLANDular tissue and mature adipose elements. Herein our aim was to present the fifth case of congenital sialolipoma, which was firstly followed up as a PAROTID GLAND hemangioma, and underline the fact that sialolipomas should be kept in mind in the differential diagnosis of congenital PAROTID GLAND masses. Case Report: A 10-month old male presented with a left-sided huge neck mass which progressed after birth. Radiologic examination revealed a tumor originating from the PAROTID GLAND filling the parapharyngeal space. Histopathologic examination of an incisional biopsy was consistent with sialolipoma. A total PAROTIDectomy with preservation of the facial nerve was performed at the age of 1 year. The postoperative recovery was uneventful with normal facial nerve function. There was no recurrence at the 24-month follow-up. Conclusion: Although it is a very rare benign tumor, congenital sialolipoma should be kept in mind in the differential diagnosis of congenital PAROTID mass.

Introduction: Lipoma is one of the most common benign neoplasm that is rarely observed in PAROTID GLANDs. In this report we are interested in presenting a new case of lipoma in superficial and deep lobes of right PAROTID GLAND. Case report: A 52-year-old woman with painless and progressive Inflation in the right preauricular region was referred. Computed tomography scanning showed a hypodense area in dimension 5.2×4 cm in right PAROTID GLAND region. Facial nerve was fully exposed also. Patient was undergone for PAROTIDectomy. Extensive removal of mass was done and Pathology report expressed a yellow-colored fatty tissue mass in dimension 5×4×2. In microscopic report lipoma of PAROTID GLAND were seen. Conclusion: Determine the exact tumor location is very important in surgical approach in these cases. As our knowledge this case seems to be an extremely case of lipoma in superficial and deep lobe of PAROTID.

Objective: Hydatid disease most commonly involves the liver and lungs; the abdominal cavity organs stand next in frequency, the PAROTID GLAND is a rare site of this disease. Hydatid disease is the most widespread, serious human cestode infection in the world. It is a zoonosis that is transmitted from domestic and wild members of the canine family. It is a serious problem in tropic areas and is seen in most areas of Iran. In children lungs are the most common site of infection whereas in adults liver is infected most frequently. It is rarely found in head and neck area and very few cases are reported in PAROTID GLAND. Case report: A 10-year old boy was presented with painless swelling of the right PAROTID GLAND. He was treated initially with antibiotics with no improvement. The microscopic examination of FNA aspirated material corresponded to an inflammatory process. The PAROTID tumor was surgically removed. Pathologic study of the cystic lesion revealed hydatid disease of the PAROTID GLAND.

Purpose: To report a case of limbal mass that was the initial manifestation of metastasis from an undifferentiated carcinoma of PAROTID GLAND.Case Report: A 56-year-old man without known systemic disease developed simultaneously a limbal and PAROTID mass in his left side. He underwent excisional biopsy of the limbal mass and subtotal PAROTIDectomy in the same session and underwent systemic evaluations. Histopathologic evaluations and immunohistochemistry staining of both limbal and PAROTIDal masses disclosed an undifferentiated carcinoma of both sites. Further evaluations revealed no other sites of involvement or metastasis. The patient underwent systemic chemotherapy and local radiotherapy.Conclusion: This is the first report of limbal mass that was the initial manifestation of metastasis from an undifferentiated carcinoma of PAROTID GLAND. It should be considered in the differential diagnosis of limbal masses.

We report a 30 year old woman who presented with a painless preauricular mass of two months duration. Superficial PAROTIDectomy was performed for the patient. Histological examination and immunohistochemical findings were in favor of mixed cellularity Hodgkin’s lymphoma (MCHD). According to this diagnosis the patient received local radiotherapy and during 4 months of follow-up no recurrence was seen. To our knowledge only one such case has been reported in the English literature to date by Uchinuma in 1988.
