Papillary cystic type of acinic cell carcinoma of parotid: fine needle aspiration cytological features of a high grade variant with oncocytic metaplasia.

A 60-year-old female developed a right parotid swelling six months after surgery for intra-oral squamous cell carcinoma. Fine needle aspiration (FNA) cytological smears showed dissociated large and small pleomorphic tumour cells with abundant mitoses and oncocytic features. A cytological diagnosis of parotid acinic cell carcinoma (ACC) was made. Histological study of the subtotal parotidectomy specimen showed a papillary cystic variety of acinic cell carcinoma (ACC-PCV). FNA cytological features in this case of ACC-PCV differs from the two previously reported cases in that it showed prominent oncocytic and high grade features and absence of papillary pattern in the cytological smears. ACC-PCV is an uncommon tumour and knowledge of its varied FNA cytological features is important for the diagnosis of this neoplasm.

[Parotid tumors: a diagnostic and therapeutic protocol in 81 surgical cases].

AIM: In the last five years we cured 81 patients divided in two groups: the first was managed inordinately, the second according to a diagnostic and therapeutic protocol. METHODS: The first 23 patients were differently evaluated, before surgery, by means of traditional sialography, US, CT, CT sialography, MR, larger bore needles and FNAB. Neoplasm enucleations, atipic resections, superficial and total conservative parotidectomies were performed. The following 58 patients were evaluated and cured according to a diagnostic and therapeutic protocol. RESULTS: Diagnostic and therapeutic time were shortened, patients endurance improved and cost lowered. DISCUSSION: We think that many diagnostic procedures are useless and delay operation that, if possible, must be performed according to principles of radical extirpation.

[Treatment of the facial nerve and the neck in malignant parotid gland tumors].

In the surgery of malignancies of the parotid gland the management of the facial nerve and of the neck is very important. In fact, many authors declared as the surgery of parotid gland can be considered as the surgery of facial nerve and others underlined the role of the neck management in a complete treatment of these neoplasms. The features of 47 cases of parotid gland neoplasms observed at the National Cancer Institut of Naples (Naples, Italy) are reported. In all cases a total parotidectomy was performed with neck dissection in case of neck metastases or electively in selected cases and resection of the facial nerve only in case of macroscopic tumor involvement. Radiotherapy was administrated in case of involvement of the facial nerve, and/or of the skin and/or of multiple neck metastases. The results of our experience emphasize as the neoplasms of the parotid gland can be treated sparing the facial nerve when it is clearly not involved without making worse prognosis; on the other side planing a neck dissection should be mandatory in case of high degree malignancies, and/or of tumors larger than T2, and/or of involvement of the facial nerve, and/or of the skin and/or cervical lymph nodes.

A case of lipoma of the deep lobe of the parotid gland.

Lipoma of the deep lobe of the parotid gland is extremely rare. A forty-two-year-old man presented with a painless, soft, and slow-growing mass in the left preauricular area. Ultrasonography and computed tomography findings were consistent with lipoma. The patient was treated with superficial parotidectomy and total excision of the mass with preservation of the facial nerve. Histologic findings confirmed the diagnosis. No recurrences were detected during 1.5 years in the postoperative period.

A case of epithelial-myoepithelial carcinoma of the parotid gland.

Epithelial-myoepithelial carcinomas comprise approximately 1% of all salivary gland neoplasms. Most tumors arise in the major salivary glands, especially in the parotid gland. We present a case of epithelial-myoepithelial carcinoma of the parotid gland in a 65-year-old male patient. Magnetic resonance imaging showed an irregular and heterogeneous mass in the left parotid gland. Superficial parotidectomy was performed. There was no evidence of recurrence during a 21-month follow-up.

[Cystic parotid lesions in HIV infection].

The appearance of parotid lesions of cystic aspect with a HIV's infections has been described in the past by foreign Authors above all coming from USA and from Africa. Similar cases has been recorded in France but only among children. The Authors report a casuistry constituted by five male sex's and white race's subjects, everyone HIV positive, suffering from mono or bilateral benign lymphoepithelial cysts. Every patient under examination presented a positive history because of the use of intravenous drug. Four of the five subjects underwent a surgical treatment of parotidectomy. Echotomography, CT and RM scanning seem to be the more sensitive diagnostic techniques. The peculiar histopathologic aspects allow us to differentiate these lesions both from the classical benign lymphoepithelial cysts and from the Warthin's tumor. The increase of the signalling of these cases seems to be connected with the progressive diffusion of the infection and with major survival of the patients thanks to chemotherapy. The majority of the Authors is agreed to recommend the surgical treatment for the possible malignant degeneration of this kind of forms. A careful clinical and diagnostic analysis of every patient with parotid swelling, above all if at risk for HIV's infection, is strictly necessary.

[Intraparotid facial nerve schwannoma: a case report].

OBJECTIVE: We describe a case of intraparotid facial nerve schwannoma. About sixty patients with intraparotid tumors have been reported in the literature. MATERIAL AND METHODS: A 89-year-old female patient presented with a history of progressive facial palsy and a left intraparotid mass. The mass was removed by parotidectomy for definitive diagnosis and treatment. We reviewed the findings in comparison with data in the literature. RESULTS: The well-encapsulated tumor arose from the superior branch of the intraparotid facial nerve. As the tumor could not be dissected from the nerve, a segment of facial nerve was sacrificed and repaired by interposing a greater auricular nerve. The final pathological diagnosis was schwannoma arising from the facial nerve. DISCUSSION: This case illustrates the clinical and pathologic features of intraparatid facial nerve schwannoma and points out the pitfalls of diagnosis and treatment. Consensus has recognized total resection surgery with facial nerve sacrifice as the most reasonable treatment for these tumors. We discuss the currently accepted management approach as well as the different treatment modalities for recovering facial function.

Spontaneous infarction of a parotid gland pleomorphic adenoma. Report of a case with cytologic and radiographic overlap with a primary salivary gland malignancy.

Pleomorphic adenoma is the most common neoplasm of the parotid gland, generally presenting as a slowly enlarging, firm, well-circumscribed, painless nodule. Occasional cases have presented after a short period of rapid growth or have been associated with pain. The vast majority of these tumors are solid, but rare examples have been associated with cystic degeneration or hemorrhage. Spontaneous and tumor-associated infarction of the parotid has been reported, but these examples have been limited to infarctions of Warthin's tumors and postoperative infarctions of salivary glands. We present the case of a 48-year-old male with a one-year history of a painful, enlarging, left parotid mass associated with paresthesia of the tongue. Computed tomographic examination of the parotid demonstrated a left superficial lobe mass with a rim of enhancement and low attenuation center. Fine needle aspiration yielded necrotic debris and atypical squamous elements that were thought to be compatible with carcinoma. A superficial parotidectomy with intraoperative frozen section revealed a pleomorphic adenoma with extensive central necrosis. To our knowledge, this represents the first reported case of an infarcted pleomorphic adenoma and illustrates the potential for misinterpretation of these cytologic and radiologic findings as indicative of malignancy.

[The cancerous recurrence of a pleomorphic adenoma of the parotid. Comments on a case].

After taking the clinical case examined as a starting point and supporting the data obtained with a literature analysis of the cancerous relapse of a parotid pleomorphic adenoma, the Authors suggested a suitable surgical operation (total parotidectomy with conservation of the facial nerve) in the treatment of parotid pleomorphic adenoma. Doing so, it is possible to avoid a relapse of neoplasm and a possible transformation into malignancy. Furthermore it might prevent the formation of parotid carcinoma.

Parotid tumor operations; the case against enucleation.

So-called mixed "encapsulated" parotid tumors are best managed by surgical procedures which avoid contact with the "capsule." Enucleation is often a hazardous and incomplete procedure. Subtotal or total parotidectomy with exposure of the facial nerve to avert accidental damage to it is the treatment of choice. Microscopic study of the periphery of such tumors reveals that the "capsule" does not fully encapsulate; hence, enucleation and lesser procedures may leave neoplastic tissue behind.Surgical procedures to achieve complete excision without endangering the facial nerve were carried out in 123 cases. There was local recurrence in one case.

End results in parotid tumors.

Management of parotid tumors can be based on a clinical classification of these lesions as being either "encapsulated" or infiltrating. The Warthin tumor (papillary cystadenolymphomatosum) is a benign encapsulated tumor, often occurring multicentrically or bilaterally especially in the lower pole area of the parotid. It is characterized clinically by its softness and fluctuation in size and a high incidence in elderly men. The so-called "capsule" of well demarcated mixed and mucoepidermoid tumors is represented by a condensation of host fibrous stroma, in the interstices of which tumor cells may be present. The "encapsulated" tumors should be excised with a "shell" of uninvolved parotid tissue. To do this safely, the facial nerve should first be isolated. Total parotidectomy is necessary only if the size of the tumor, the multiplicity of recurrences, or the infiltrating nature of the tumor are such that complete eradication of the primary site must be done. Radical neck dissection is never performed electively except in the small group of nonencapsulated infiltrating primary lesions. In a series of cases of previously untreated parotid tumors treated by the method outlined, the local parotid recurrence rate was less than 1 per cent.

Calcifying epithelioma of Malherbe--a case report of a large preauricular tumour.

Calcifying epithelioma of Malherbe (pilomatrixoma) is a relatively uncommon benign skin tumour of hair follicle origin. It usually presents in the face and upper extremities of young adults as an asymptomatic subcutaneous or dermal tumour. Treatment is surgical excision. This paper presents a case of a large tumour in the preauricular region with difficulty in diagnosis preoperatively and required a superficial parotidectomy to clear the tumour from the facial nerve.

SIALADENITIS AND MAJOR SALIVARY GLAND TUMORS IN CHILDREN: EXPERIENCE AT LOS ANGELES CHILDRENS HOSPITAL AND A REVIEW OF THE LITERATURE.

Except for mumps, the benign lesions most frequently seen in the salivary glands of a child are parotitis, hemangioendotheliomas and mixed tumors. Carcinoma and sarcoma are uncommon. Rapid growth and pain are features of malignant change. Chronic parotitis usually subsides under conservative treatment. If operation is necessary, total parotidectomy is advisable. Scout x-ray films and sialangiographic examination are useful in differentiating an inflammatory lesion from a neoplastic growth.The treatment of choice for a non-inflammatory tumor is surgical excision, for most parotid tumors are radioresistant. Small masses should be completely excised for pathological evaluation. Since operation entails risk of damage to the seventh nerve, incisional biopsy may occasionally be indicated in the case of a large diffuse lesion for it is very likely to be benign and operation unnecessary. The risks of seventh nerve damage are magnified in a child as the anatomic structures are smaller and the nerve lies in a more superficial position.

[Clinical features of papilliferous cystadenolymphoma of the parotid (Whartin's tumour) (author's transl)].

Out of 222 parotid tumours treated by surgery 22 (10%) proved to be cystadenolymphoma papilliferum. The tumour was found predominantly in men over fifty, tended to grow rapidly often causing pain. Suspicion of papilliferous cystadenolymphoma (a parotid tumour in older men) must be confirmed by early operation. The surgical procedure for cystadenolymphoma is like that for pleomorphic adenoma (exposure of the facial nerve followed by partial parotidectomy). An extracapsular dissection is not recommended.

[Primary malignant lymphoma of the parotid gland. Report of a case].

Primary malignant lymphoma of the parotid gland is often correlated, in literature data, with inflammatory autoimmunological disease of the salivary gland. Finding of blasticlymphoid cells in myoepithelial scialoadenitic areas in a case of parotid disease is described by the Authors. Needle may be useful in detecting these high radio-chemosensitive neoplasms to reduce the occurrence of complications of total parotidectomy.

Multiple intraparenchymal parotid calculi: a case report and review of the literature.

We describe an unusual case of bilateral intraparenchymal parotid stones with unilateral parotitis in a 17-year-old boy. The patient went on to develop multiple parotid abscesses, which we treated with a superficial parotidectomy. To our knowledge, this is only the second report of intraparenchymal parotid stones in a pediatric patient.

Oncocytic carcinoma of the parotid gland: report of a new case.

Prior to 2003, only 39 cases of oncocytic carcinoma of salivary gland origin had been reported in the English-language literature. We report a new case, which occurred in a 48-year-old woman whose disease had metastasized to regional lymph nodes. She was treated by radical parotidectomy, with sacrifice of the facial nerve, and radical neck dissection. At the 3-year follow-up, she remained free of disease. Our review of the literature suggests that patients with such tumors who undergo aggressive surgery rather than conservative treatment have the best prognosis.
