The masticator space is an anatomical and functional entity centered on the mandibular ramus, which divides it into medial and lateral compartments. The masticator spaces considered paired supra-hyoid cervical spaces on each side of the face that extend from the angle of the mandible to the parietal bone. The masticator space contains the mastication muscles, posterior mandible, and mandibular nerve. They are separated from the nasopharynx by the parapharyngeal spaces bilaterally. Primary malignancy of the masticator space is very uncommon.Here we report a diagnostic dilemma of primary masticator space malignancy mistaken by nasopharyngeal carcinoma as the patient 40-year old gentleman presented with left lateral rectus palsy and left nasopharynx fullness.

Purpose: Radiation therapy is a standard treatment for nasopharyngeal carcinoma. Diplopia due to radiation damage to the sixth nerve significantly erodes the patient’s quality of life. This study investigated the effectiveness of extraocular surgery in the treatment of delayed diplopia caused by radiation therapy. Methods: A retrospective case series of 16 patients (7 men and 9 women) with delayed diplopia after radiation therapy for nasopharyngeal carcinoma was enrolled in the study. Unilateral lateral rectus resection was performed under topical anesthesia. Follow-up time was more than 12 months. Outcome measures were prism diopter and self-reported symptoms. Results: All patients diagnosed with sixth nerve palsy reported elimination of symptoms on postoperative day 1 without complications. One patient required a second procedure due to recurrence of symptoms. At 12-month follow-up, no patient reported recurrence of symptoms. The absolute horizontal deviation significantly decreased from a preoperative value of 16 prism diopter to a value of 1.5 prism diopter postoperatively (p < 0.001). Conclusion: These results suggest that unilateral lateral rectus resection under topical anesthesia is an effective treatment for delayed diplopia after radiation therapy for nasopharyngeal carcinoma. A large randomized prospective study to confirm these findings is warranted.

AbstractHere, the authors describe a case of 25-year-old man diagnosed with dural plasmacytoma involving calvarium with soft tissue extension. Magnetic resonance imaging (MRI) revealed extra-axial heterogeneously enhancing soft tissue mass lesion in the left parieto-occipital region with a dural tail mimicking meningioma, destroying the left parietal bone, and bulging into the scalp. Mass was excised and histopathologic examination revealed plasmacytoma with amyloid deposition. There is no recurrence after postoperative radiotherapy and 2 years of follow-up, although the future course is still not certain. The clinician should consider alternative diagnosis other than meningioma prior to proceeding to surgery if the dural-based lesion is involving calvarium and soft tissue extension.

Nongenital HSV 1 presents outside the mucus membrane. Our patient had unusual presentation that caused diagnostic dilemma. 30-year-old native Nigerian female coming with fiancée to the United States presented to our service one day after arrival through ER with a lesion on her right ankle. She was diagnosed with cellulitis, started on antibiotics, and admitted to hospital. She had fever of 39.1°C. Head and neck exam showed multiple sized lesions over tongue and palate and inner aspect of lower lip. Abdomen and genital exam was normal. Skin exam showed lesions over the face and lesions over the lateral aspect of the right leg. There was ulcerated lesion over the right lateral malleolus with surrounding erythema and edema. Her tests showed elevated ESR of 98; HIV test was negative; CT scan of the ankle showed no abscess or osteomyelitis. TB quantiferon was indeterminate; AFB stain and culture were negative; HSV IgM was elevated at 1 : 16; RPR was negative; ANA was negative; malaria screen was negative, and blood cultures were negative for bacteria, fungus, and virus. Debrided wound had no growth of bacteria or fungus or virus. This case illustrates the unusual presentation of the HSV1 outside the mucus membrane and how it can be confused with other conditions that required extensive tests. Therapeutic trail with antiviral medications resolved lesions over the leg and face.

In this paper the author gives a description of a fossil skull and certain of the teeth of a quadruped of the size of a lion, in which he points out the characters indicative of its carnivorous habits and of its affinities to the marsupial order. The large size of the temporal fossæ, meeting to form a low crest on the parietal bone, and bounded behind by a strong occipital crest; together with large carnassial teeth in both upper and lower jaws, evince the carnivorous habits of the extinct species. Its marsupial nature is, in the author’s opinion, demonstrated by the following cranial structures:—A large vacuity in the bony palate; a proportionally large lacrymal bone extending upon the face and perforated by the lacrymal canal, anterior and external to the orbit; three external precondyloid foramina; the perforation of the basisphenoid by the entocarotid canal; the great interval between the foramen ovale and foramen rotundum; the separation of the tympanic from the petrous bone; and the development of the ‘bulla auditoria’ in the alisphenoid; the position of the outlet for a vein from the lateral sinus behind and above the root of the zygoma; finally, the low and broad occiput, and the very small relative capacity of the brain-case.

AbstractThe majority of maxillofacial gunshot wounds are caused by suicide attempts. Young men are affected most often. When the lower one-third of the face is involved, airway patency (1.6% of the cases) and hemorrhage control (1.9% of the cases) are the two most urgent complications to monitor and prevent. Spinal fractures are observed with 10% of maxillary injuries and in 20% of orbital injuries. Actions to treat the facial gunshot victim need to be performed, keeping in mind spine immobilization until radiographic imaging is complete and any required spinal stabilization accomplished. Patients should be transported to a trauma center equipped to deal with maxillofacial and neurosurgery because 40% require emergency surgery. The mortality rate of maxillofacial injuries shortly after arrival at a hospital varies from 2.8% to 11.0%. Complications such as hemiparesis or cranial nerve paralysis occur in 20% of survivors. This case has been reported on a victim of four gunshot injuries. One of the gunshots was to the left mandibular ramus and became lodged in the C4 vertebral bone.MaurinO, de RégloixS, DubourdieuS, LefortH, BoizatS, HouzeB, CulomaJ, BurlatonG, TourtierJP.

The clinical presentations of herpes simplex virus (HSV) infections are varied and range from asymptomatic to a prodrome of tingling and burning followed by painful vesicles, erosions and ulcers. Resolution leads to latent infection of the sensory ganglia. HSV-1 is associated with most of the nongenital HSV–induced infections and HSV-2 is generally associated with anogenital lesions; however, lesions at either site may be caused by both viruses. In persons living with HIV (PLHIV), the lesions have been described as verrucous/hypertrophic, exophytic or vegetative and may suggest a neoplastic rather than an infective process and this can be a diagnostic dilemma in resource-limited countries with no access to confirmatory diagnostic testing for HSV. We report on two PLHIV who developed rapidly growing lesions on the face that clinically mimicked neoplasia but were found to be HSV-associated squamous proliferative lesions which responded to high dose acyclovir.
