Abstract

Leiomyosarcoma of the head and neck is very rare, as only about 100 cases have been reported; of these, only 3 cases have been previously reported in the parapharyngeal space. We report the fourth such case, and we review the features of this entity. The patient was an 84-year-old woman who presented to the emergency department for treatment of an 18-month history of right-sided headache, a 6-month history of right-sided hearing loss and nasal obstruction, and a 2-month history of dysphagia. Physical examination revealed a bulge in the right side of the soft palate and the right lateral nasopharyngeal wall and complete obstruction of the right eustachian tube. Indirect laryngoscopy detected a bulge in the right lateral hypopharyngeal wall. Otoscopy revealed otitis media with effusion in the right ear. Imaging demonstrated a space-occupying lesion in the right parapharyngeal space that extended from the base of the skull to the level of the hypopharynx. Biopsy and histology identified the mass as a leiomyosarcoma. Metastasis to the brain was discovered shortly thereafter, and the patient died 10 months later. The unusual presentation of head and neck leiomyosarcoma requires a high index of suspicion and appropriate diagnostic imaging. Surgical excision is the recommended treatment when feasible; chemoradiotherapy does not appear to affect disease progression.

Abstract

We report the case of a 19-year-old man with neurofibromatosis type 1 who presented for evaluation of odynophagia, left-sided hemiparesis, multiple café au lait spots all over his body, and numerous subcutaneous and cutaneous neurofibromas. Imaging revealed the presence of two large neurofibromas-a 60 x 50 x 35-mm tumor in the left parapharyngeal space and an intradural tumor measuring 25 mm in diameter. We removed the larger tumor via a transoral route with the Harmonic Scalpel. The size of this tumor far exceeded the size of any other reported tumor removed in this manner. Various approaches to the parapharyngeal space have been described in the literature. To the best of our knowledge, this case represents the first report of a transoral removal of a huge parapharyngeal space neurofibroma with a Harmonic Scalpel.

Primary cervical thoracic duct cyst: A case report and review of the literature

July 13, 2014     Ameet Kumar, MS; T.S. Ramakrishnan, MS; Samaresh Sahu, MD, DNB
article

Abstract

Thoracic duct cysts are uncommon entities that are usually found in the thoracic segments of the thoracic duct. The presence of a thoracic duct cyst in the cervical area has been rarely reported. Etiologically, these cysts can arise either as a primary growth or secondary to trauma, obstruction, or inflammation. This entity was first described in 1964, and only 33 cases have been previously reported in literature. Of these, 16 cases involved a primary cyst. We report a new case of a primary thoracic duct cyst, and we discuss its presentation, diagnosis, and management, with an emphasis on meticulous surgical technique. We also review the relevant literature.

Petrosquamosal sinus discovered during mastoidectomy, and its radiologic appearance on temporal bone CT: Case report and brief review

July 13, 2014     Hyun Joon Shim, MD; Seong Jun Song, MD; Ki Woong Chung, MD; Sang Won Yoon, MD
article

Abstract

We report the case of a 47-year-old woman who underwent a mastoidectomy. Preoperative computed tomography demonstrated an unusually distended bony canal that passed through the superolateral portion of the right petrous bone. Intraoperatively, we identified the anomaly as a petrosquamosal sinus (PSS). This unusually dilated venous channel had arisen from the adjacent sigmoid sinus. A PSS is an emissary vein of the posterior fossa that courses along the petrosquamosal junction, connecting the sigmoid or transverse sinus with the extracranial venous system. While it usually regresses during fetal life, a dilated PSS occasionally persists into adulthood. Its anatomic course may lead to problematic bleeding during mastoidectomy.

article

Abstract

Ossifying fibromyxoid tumors are rare soft-tissue neoplasms, usually with an indolent course. However, atypical/malignant variants have been described, showing either local recurrence after complete excision or metastasis to the lungs, mediastinum, adrenals, or soft tissue. We report the case of an ossifying fibromyxoid tumor of the left ankle that metastasized to the lung and thyroid gland 12 years after the initial diagnosis and surgical treatment. To our knowledge, this is the first reported case of this neoplasm metastasizing to the thyroid gland.

Endoscopic management of spontaneous CSF rhinorrhea with septal graft and middle turbinate rotational flap technique: A review of 31 cases

article

Abstract

Spontaneous cerebrospinal fluid (CSF) rhinorrhea poses a major challenge to rhinologists. Much controversy attends its cause, pathophysiology, management, and prognosis. It has been suggested that endoscopic placement of a septal graft with a middle turbinate rotational flap may represent the ideal approach to closing skull base defects. We conducted a retrospective chart review to compile the results of this approach in 31 patients with spontaneous CSF rhinorrhea-22 women and 9 men, aged 18 to 67 years (mean 38.5 ± 8.96) at diagnosis. After one surgery, success had been achieved in 27 of these patients (87.1%). The remaining 4 patients underwent a second surgery, and 2 of them experienced a successful closure. In the remaining 2 patients, a third surgery was still unsuccessful, and they were referred to the neurosurgical team for a shunt procedure. Thus, the overall success rate with the septal graft and a middle turbinate rotational flap was 93.5% (29/31). Septal grafts and middle turbinate flaps are easy to harvest and easy to place. Accurate localization of the defect, meticulous surgical technique, and cerebral dehydrating measures may improve outcomes. Further study of spontaneous CSF rhinorrhea to better evaluate its pathophysiology and prognostic factors is warranted.

Abstract

We conducted a retrospective observational study to determine the spectrum and antibiotic sensitivity pattern of organisms isolated in otorhinolaryngologic (ORL) infections. We reviewed the laboratory culture and sensitivity records of 4,909 patients-2,773 males (56.5%) and 2,136 females (43.5%), aged 2 to 90 years (mean: 45.3 ± 12.6)-who had been seen at two government hospitals in Malaysia. Of this group, 4,332 patients had a respiratory tract infection (88.2%), 206 had an ear infection (4.2%), 188 had a deep neck infection (3.8%), and 183 had an oropharyngeal infection (3.7%). The most common isolated organisms were Klebsiella spp, Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, methicillin-susceptible S aureus, coagulase-negative S aureus, and Acinetobacter baumannii. We also identified the antimicrobial susceptibility of these organisms. We conclude that since the spectrum of causative pathogens in some infections differs between tropical and nontropical areas of the world, tropical hospitals should not completely adopt the antibiotic guidelines for ORL infections that have been recommended for hospitals in nontropical regions. We hope that our review and analysis of local data will help practitioners in Malaysia develop an appropriate prescribing policy with respect to ORL pathogens and antimicrobial susceptibility. The goal is to reduce the morbidity and mortality associated with these infections.

Condyloma acuminatum of the buccal mucosa

June 8, 2014     Rashmi Jaiswal, PhD; Manoj Pandey, MS; Mridula Shukla, DipNB; Mohan Kumar, MD
article

Abstract

Condyloma acuminatum is a human papillomavirus (HPV)-induced disease. It is usually transmitted sexually, and it frequently occurs in the anogenital area. A finding of condyloma acuminatum in the oral cavity is rare. Besides HPV, other risk factors for oral condyloma include chewing betel quid and smoking. We report the case of a 52-year-old man who presented with a 2 x 2-cm verrucous white patch on his buccal mucosa. He was habituated to both betel quid and cigarette smoking. A biopsy of the lesion identified it as a verrucous hyperplasia of the squamous epithelium with HPV-related koilocytic changes. The lesion was excised, and further histopathology identified it as condyloma acuminatum. The patient was disease-free 9 months postoperatively. The possibility of condyloma acuminatum should be considered in the differential diagnosis of an oral white lesion. The most common treatments are surgical excision, cryosurgery, electrocautery, and laser excision. There is no known role for antiviral therapy.

Abstract

Scalp angiosarcoma represents a therapeutic challenge to all disciplines. This case report demonstrates the potential usefulness of helical tomotherapy (HT) as a new radiotherapeutic treatment option. A 71-year-old woman presented with a superficial angiosarcoma of the scalp, forehead, and left pre- and postauricular areas, with several nodular ulcerating and bleeding lesions. Irradiation of the gross tumor was performed with a total dose of 70 Gy in 2-Gy fractions and of the left cervical lymph nodes with 56 Gy in 1.6-Gy fractions. Good target coverage was achieved without compromising organs at risk, notably the brain. Treatment was very fast (661 seconds per fraction) and was administered with minimal acute toxicity (National Cancer Institute Common Toxicity Criteria: grade 2 erythema and grade 2 dysphagia). During treatment, tumor nodules dissolved into hyperkeratosis. We conclude that with HT, irradiation of the scalp and cervical lymph nodes can be conducted with minimal acute toxicity and without junction problems.

Sebaceous carcinoma of the parotid gland: A case report and review of the literature

article

Abstract

Sebaceous carcinoma is a rare malignancy primarily affecting the periocular sebaceous glands. Sebaceous carcinoma of the parotid gland is exceedingly rare, with only 30 cases reported in the literature. Our case brings this total to 31. We present a case involving a 57-year-old man with a slowly enlarging, right tail-of-parotid mass abutting the ear lobule with overlying skin discoloration. Excision of the mass with superficial parotidectomy was performed, and microscopic examination demonstrated sebaceous carcinoma with positive margins. Subsequently, the patient underwent a completion parotidectomy and inferior auriculectomy with no evidence of residual tumor. Six months after postoperative adjuvant radiotherapy, the patient remains tumor-free. The clinical and morphologic features of this tumor are discussed.
