Objective: The feasibility, surgical outcomes and possible risks and complications encountered during a facelift procedure for patients with parapharyngeal space (PPS) tumor were analyzed. Method: This retrospective analysis examined 10 patients who had undergone surgery for PPS tumor using a facelift incision at our institutes between April 2015 and August 2019. Results: This study included four retro-styloid (benign nerve sheath tumor) and six pre-styloid tumors (pleomorphic adenoma). Average tumor dimensions were 4.1 x 4.2 x 3.8 cm respectively. None of the patients needed conversion to conventional open resection. Transient sensory changes in the auricle occurred in 30 % of the patients; however, all recovered within four months. In all the patients, postoperative scars were fully concealed by the auricle and hair. No recurrences were detected during a mean follow-up period of 16.6 months. Conclusions: The facelift procedure provides adequate visualization, workspace and excellent cosmetic results in properly selected cases.

Transoral Resection

The purpose of this study was to investigate the feasibility, safety, and efficacy of the resection of parapharyngeal space (PPS) tumors via an endoscopic transoral approach. We reviewed 9 patients who were diagnosed with PPS tumors and who were treated with an endoscopic transoral approach. PPS tumors ranging from 2.5 to 6 cm were removed completely with no complications and excellent recovery (mean inpatient hospital stay: 6.89 days). Pathology was pleomorphic adenoma (n =7), schwannoma (n = 1) and malignant pleomorphic adenoma (n = 1). For the malignant lesion, the patient underwent postoperative radiotherapy (70 Gy). There was no radiographic evidence of recurrences, with mean follow-up of 11.22 months (range: 3 to 20). We conclude that resection of PPS tumors via an endoscopic transoral approach appears to be feasible, safe, and effective. Potential advantages of this approach include an excellent surgical view, rapid surgical access, less tissue injury, avoidance of external scar, fewer postoperative complications, and less morbidity.

A benign peripheral nerve sheath tumor is illustrated in a case presentation of a painful mass in the medial thigh, with paresthesias radiating along the course of the saphenous nerve. The presenting features, appropriate workup, treatment timing, surgical strategies, follow-up, and results for nerve-associated masses are outlined. Specific imaging findings for peripheral nerve sheath tumors on contrast-enhanced MR imaging and the merits of high-resolution ultrasound are detailed. The typical features of a well-defined and noninvasive peripheral nerve tumor, the principles of exploration, and microsurgical enucleation technique are highlighted. Other nerve tumor entities that should be considered in the differential diagnosis, as well as their respective features, are discussed.

Abstract Objective Malignant peripheral nerve sheath tumor (MPNST) arises from nerve sheaths, mostly seen in peripheral nerves but rare in craniospinal nerves. The information available in the literature to build up treatment strategy and improve clinical outcomes is scarce. We are reviewing cases from our institute, with emphasis on radiological features for early differentiation from its benign variants. Methods We analyzed pathologically diagnosed cases retrospectively from January 2007 to December 2018 at our institute. Clinicoradiological details and treatment parameters were collected from medical records for evaluation. Each case was contacted telephonically for final clinical follow-up at the time of writing the manuscript. Results A total of seven cases of MPNST were diagnosed in the last 10 years. It included four intracranial and three spinal cases. The mean age for the cohort was 34.3 years, with five females. We could achieve gross total resection (GTR) and subtotal resection in four (57.1%) and two (28.6%) cases, respectively. We could achieve an overall survival of 57.1% in the average follow-up of 28.2 months (range: 8–84 months). Conclusion MPNST is a rare tumor with a bad prognosis. Radical surgical resection is the mainstay of the treatment, but it is not always possible to achieve it because of the inaccessible location and large size of lesions. Preoperative diagnosis is challenging; however, few radiological findings may give a clue toward it. As a disease entity overall, it has a poor outcome with a high rate of fatality.

Long Term Follow Up

Melanotic schwannoma (MS) is a rare nerve sheath tumor with fewer than 200 cases reported. MS has uncertain malignant potential and comprises 1% of all nerve sheath tumors with a predilection for the spinal nerve roots. An even rarer location for this tumor is the vagina. Up to 55% of MSs that contain psammoma bodies are associated with the Carney complex, an autosomal dominant syndrome. Criteria for malignancy in MS are still not well established and long term follow-up of patients is recommended. A 26-year-old woman presented with a bleeding vaginal tumor which was diagnosed as MS following excision. The clinical, histopathological, and immunohistochemical features of this tumor are discussed.

History Of

ABSTRACTMalignant peripheral nerve sheath tumor (MPNST) is a rare soft tissue sarcoma. Most arise in association with major nerve trunks. Their most common anatomical sites are the proximal portions of the upper and lower extremities and the trunk. MPNSTs have rarely been reported in literature to occur in other unusual body parts. We review all such cases reported till now in terms of site of origin, surgical treatment, adjuvant therapy and outcome and shortly describe our experience with two of these cases. Both of our case presented with lump at unusual sites resembling neurofibroma, one at orbitotemporal area and other in the paraspinal region with characteristic feature of neurofibroma with the exception that both had very short history of progression. They underwent gross total removal of the tumor with adjuvant radiotherapy postoperatively. At 6‑month follow‑up both are doing well with no evidence of recurrence.

Significant Difference

Stand-alone (SA) zero-profile implants are an alternative to cervical plating (CP) in anterior cervical discectomy and fusion (ACDF). In this study, we investigate differences in surgical outcomes between SA and CP in ACDF. We conducted a retrospective analysis of 166 patients with myelopathy and/or radiculopathy who had ACDF with SA or CP from Jan 2013–Dec 2016. We measured surgical outcomes including Bazaz dysphagia score at 3 months, Nurick grade at last follow-up, and length of hospital stay. 166 patients (92F/74M) were reviewed. 92 presented with radiculopathy (55%), 37 with myelopathy (22%), and 37 with myeloradiculopathy (22%). The average operative time with CP was longer than SA (194 ± 69 vs. 126 ± 46 min) (p < 0.001), as was the average length of hospital stay (2.1 ± 2 vs. 1.5 ± 1 days) (p = 0.006). At 3 months, 82 patients (49.4%) had a follow-up for dysphagia, with 3 patients reporting mild dysphagia and none reporting moderate or severe dysphagia. Nurick grade at last follow-up for the myelopathy and myeloradiculopathy cohorts improved in 63 patients (85%). Prolonged length of stay was associated with reduced odds of having an optimal outcome by 0.50 (CI = 0.35–0.85, p = 0.003). Overall, we demonstrate that there is no significant difference in neurological outcome or rates of dysphagia between SA and CP, and that both lead to overall improvement of symptoms based on Nurick grading. However, we also show that the SA group has shorter length of hospital stay and operative time compared to CP.

Tumorlike Lesion

Over a 16-year period, 190 tumors and tumorlike lesions from 179 pet rabbits were submitted for histopathologic examination. A total of 23 different tumor types and 1 tumorlike lesion were diagnosed. The most common diagnoses were trichoblastoma, collagenous hamartoma, and Shope fibroma. Viral-induced tumors were Shope fibroma (19) and Shope papilloma (2). Common nonviral epithelial tumors included trichoblastoma (59), squamous cell carcinoma (5), squamous papilloma (4), trichoepithelioma (3), and apocrine carcinoma (3). Common mesenchymal tumors were lipoma (10), liposarcoma (3), myxosarcoma (9), malignant peripheral nerve sheath tumor (8), fibrosarcoma (7), and leiomyosarcoma (4). Malignant melanoma was diagnosed in 8 rabbits. Collagenous hamartomas were diagnosed in 26 rabbits. Mesenchymal proliferations occurred significantly more often in male rabbits than in females. Collagenous hamartomas and myxosarcomas occurred exclusively in male animals, and 3 rabbits had multiple collagenous hamartomas. Immunohistochemistry was applied in cases in which a definite diagnosis could not be reached on hematoxylin and eosin slides. Follow-up information was received in 19 cases. Carcinomas recurred (2 of 3) or metastasized (1 of 3), whereas sarcomas frequently recurred (7 of 12). One malignant melanoma (1 of 3) and one poorly differentiated round cell neoplasm recurred (1 of 1). This is the first comprehensive retrospective analysis on skin neoplasia in pet rabbits.
