OBJECTIVE AND IMPORTANCE: A case of metastasis to the pituitary gland from a ductal adenocarcinoma of the salivary gland is presented. Metastasis to this site is rare, and a salivary gland source has never previously been described. CLINICAL PRESENTATION: This patient presented with hypopituitarism, including diabetes insipidus. INTERVENTION: A craniotomy was performed to alleviate visual loss. The histological features of the sellar tumor were identical to those of a tumor removed from the parotid gland 18 months earlier. CONCLUSION: Although intrasellar tumors originating from embryonic rests of salivary gland tissue have been reported, metastasis from a malignant neoplasm arising within a true salivary gland is also possible and should not be excluded from consideration for patients in whom a salivary gland-like tumor is discovered in the sella turcica.

PURPOSE: To compare retrospectively radiotherapy with neutrons, photons, and a photon/neutron mixed beam in patients with advanced adenoid cystic carcinoma of the head and neck. Local control, survival, distant failure, and complications were analyzed. MATERIALS AND METHODS: Between 1983 and 1995, 75 patients with inoperable, recurrent, or incompletely resected adenoid cystic carcinoma of the head and neck received radiotherapy that consisted of either fast 14.1 MV DT neutrons (median dose 16 neutron Gy), linac-based photon irradiation (median dose 64 photon Gy), or both (median dose 8 neutron Gy and 32 photon Gy). Follow-up ranged from 1 to 160 months (median 51 months), and the surviving patients had a minimum follow-up of 3 years at the time of analysis. RESULTS: The actuarial 5-year local control was 75% for neutrons, and 32% for both mixed beam and photons (P = 0.015, log-rank). This advantage for neutrons in local control was not transferred to significant differences in survival (P > 0.1). The survival is dictated by the tumor diseases due to distant metastases occurring in 29 (39%) of the 75 patients. Positive lymph nodes were the only significant factor (P = 0.001) associated with the development of distant metastases although negative lymph nodes did not predict absence of distant metastases, but predicted a delay of occurrence. In multivariate analysis postoperative radiotherapy (P = 0.003) and small tumor size (P = 0.01) were associated with high local control, while primary therapy (P = 0.006) and negative lymph nodes (P = 0.01) were associated with longer survival. While acute toxicity was similar in all three radiotherapy groups, severe late grade 3 and 4 toxicity tended to be more prevalent (P > 0.1) with neutrons (19%) than with mixed beam (10%) and photons (4%). CONCLUSION: Fast neutron radiotherapy provides higher local control rates than a mixed beam and photons in advanced, recurrent or not completely resected adenoid cystic carcinoma of the major and minor salivary glands. Neutron radiotherapy can be recommended in patients with bad prognosis with gross residual disease (R2), with unresectable tumors, or inoperable tumors. The type of radiation does not impact survival, which is dominated by the high number of distant metastases.

BACKGROUND AND PURPOSE: An optimization algorithm has been developed to determine the best beam-arrangement for a small number of intensity-modulated radiotherapy (IMRT) fields. The algorithm is designed to avoid, if possible, beam-orientations that pass through organs-at-risk (OARs) with low radiation tolerance. MATERIALS AND METHODS: An independent, fast IMRT algorithm based on the Bortfeld algorithm was developed to determine the profile of the intensity-modulated beams (IMBs) for each beam-arrangement and a fast-simulated-annealing algorithm finds the 'optimal' beam-arrangement. The final beam-arrangement was transferred to the CORVUS (NOMOS Corporation) treatment planning system, and the IMBs were re-optimized for comparison with a standard nine-field, equi-spaced arrangement. The algorithm has been initially tested on a single example patient, with a parotid gland carcinoma. RESULTS: The nine-field, IMRT plan for an example patient with a parotid gland tumour significantly reduced the dose to the cochlea compared with the conformal radiotherapy plan. In addition, the planning-target-volume (PTV) homogeneity was improved, but the plan produced a higher dose to the contralateral parotid (73% of the OAR received more than 6 Gy). The beam-orientation optimization algorithm produced a three-field plan that greatly reduced the dose to the contralateral parotid (maximum dose of 2 Gy), whilst maintaining the PTV dose homogeneity and the reduced cochlear dose of the nine-field plan. Some changes in the dose to the other OARs, namely the brain and the oral cavity, were seen, but were deemed not to be clinically significant. CONCLUSIONS: In conclusion, IMB-orientation optimization for head and neck treatment sites can produce improvements in treatment plans with only a few fields.

Hemifacial spasm (HFS) has been defined as consisting of brief clonic jerking movements of the facial musculature, beginning in the orbicularis oculi with downward spreading to other facial muscles. HFS, perhaps the most common of the abnormal involuntary facial movements, has been classically ascribed to vascular loop compression at the root exit zone of the facial nerve. Causes other than such vascular loops are rare in the medical literature. Here we present three case studies in which the phenomenology of the HFS was atypical in onset and evolution. Using these three patients as introduction to the topic, we reviewed the literature of all cases of HFS with causes other than the vascular loop. In these three cases, HFS was caused by (1) a parotid gland tumor, (2) a cerebellopontine angle meningioma, and (3) an acoustic schwannoma. We also discuss the radiological findings as well as possible differences in the genesis of HFS and phenomenology in such cases and present recommendations on how to evaluate these patients.

Fine-needle sampling (FNS) of five cases of epithelial-myoepithelial carcinoma, three primary tumors, and two local recurrences, was performed preoperatively in five patients. Cytologic diagnoses of malignancy were established in all tumors (three were reported as adenoid cystic carcinoma, two as adenocarcinoma not otherwise specified). Material for cytologic evaluation was satisfactory in all cases. Adenoid cystic carcinoma, polymorphous low-grade adenocarcinoma, papillary cystadenocarcinoma and cellular type of pleomorphic adenoma are the main differential diagnoses.

The necessity of fine-needle aspiration biopsy (FNAB) in the diagnosis and treatment of parotid gland lesions is still controversial. We examined the accuracy of cytology and histology in a review of 128 parotid gland tumors who underwent surgery with FNAB, n = 102 and/or frozen section examination (FS), n = 94. The diagnostic sensibility and specificity for malignant or benign lesions was respectively 81.5% and 97.5% for FNAB and 75% and 100% for FS as compared with definite histology (110 tumors were benign and 18 malignant). Insufficient material for FNAB evaluation was found in 12 patients mainly with small tumors (p = 0.043) or with tumors located in the deep process of the parotid gland (p = 0.029). Surgery was inappropriate (superficial lobe resection for malignant tumor) because of 4 false negative FS diagnoses. FNAB offers valuable information in the diagnosis of nonsurgical lesions and permits to avoid FS if FNAB identify a benign lesion. FS remains mandatory if FNAB evaluation is not possible or suggests a neoplastic tumor.

The biological activity of acinic cell carcinoma is uncertain. Histological dedifferentiation is one possible reason for recurrent disease, and this study was undertaken to assess its importance in acinic cell carcinoma. The initial and recurrent specimens from five patients with acinic cell carcinoma were assessed histologically and using flow cytometry, AgNOR estimation and morphometric analysis for evidence of dedifferentiation. No objective evidence of a change in biological aggressiveness in recurrent acinic cell carcinoma was identified. In this limited series of a rare salivary gland tumour, it would appear that factors other than dedifferentiation, such as close/involved margins, histological type and stage have a more meaningful effect on the likelihood of recurrence and prognosis.

Metastases to the salivary glands from distant neoplasms are unusual, with most reported cases involving the parotid gland. Metastatic deposits in the submandibular gland are extremely rare with bilateral involvement not previously reported. We present the case of a patient with advanced breast carcinoma who has had metachronous involvement of both submandibular glands and review the literature on this subject.

Facial paralysis in association with a parotid mass is usually associated with a diagnosis of malignancy. Benign parotid neoplasms and inflammatory processes resulting in facial paralysis are extremely rare. This report describes such a case and highlights some of the difficulties surrounding the diagnosis and management of these cases.
