Nasopharyngeal carcinoma in Sarawak : a 10-year review and update.

AIM: Nasopharyngeal carcinoma (NPC) is prevalent in certain regions, particularly Southeast Asia and Southern China. In Malaysia, it is notably frequent among the Bidayuh community. This study presents a comprehensive review of NPC cases diagnosed and treated at Sarawak General Hospital from 2010 to 2020. METHOD: A retrospective data collection was conducted using the clinical records of patients who were histopathologically diagnosed with NPC at the Otolaryngology-Head & Neck Clinic and the Radiotherapy & Oncology Clinic at Sarawak General Hospital. RESULT: The study comprised a total of 892 patients from 2010 to 2020. Males outnumbered females 3-to-1, with a mean age of 51 years (standard deviation: 13.9). The largest groups of patients were the Iban (34%) and the Bidayuh (21%), followed by the Chinese (19%) and the Malay (15%). The Bidayuh had the highest incidence rate with 81 cases per 100,000. Only 10% of the study population had a family history of NPC. The most common presentation was a neck lump (64.5%). Distant metastasis was discovered in 20% of patients. 82% of the cases were stage 3 or 4 at the time of presentation. The histological types of the 892 cases were mainly undifferentiated carcinoma (73%). Eighty-six patients developed recurrence, with 83% experiencing local recurrence, 10% developing distant metastasis, and 7% developing regional recurrence. Treatment for recurrence included nasopharyngectomy, neck dissection, and chemotherapy. CONCLUSION: The study highlights a significant incidence of NPC among the Bidayuh. Emphasis on screening and early detection is crucial for better outcomes, with lifelong follow-up recommended.

Cavernous sinus fungal infection: a rare case.

Intracranial fungal infection of the cavernous sinus is a condition that usually affects immunocompromised individuals and is rarely seen in immunocompetent individuals. It is a potentially life threatening condition which requires prompt treatment. Here we present a case of an immunocompetent patient with a fungal infection of the cavernous sinus.

A Rare Case and Literature Review of Endoscopic Endonasal.

We report a rare case of localized anterior clinoid mucocele (ACM) with acute visual loss and a literature review of the endoscopic endonasal surgery. We advocate that endoscopic endonasal approach is the best choice. To our knowledge there a limited report on localized ACM that treated via endoscopic endonasal approach.

Pharyngeal Lipoma-A Potentially Life Threatening Presentation.

Pharyngeal lipoma of the upper aero-digestive system is extremely rare. It is typically benign, slow growing and symptoms would depend on its size and location. Surgical intervention is often needed especially for large tumour with impending airway obstruction. Here we present a case of potentially life threatening presentation of pharyngeal lipoma.

Endoscopic Endonasal Approach in Clival Chordoma Surgery: Case Series.

Chordomas are rare and slow-growing locally destructive bone tumors that can develop in the craniospinal axis. It is commonly found in the sacrococcygeal region whereas only 25-35% are found in the clival region. Headache with neurological deficits are the most common clinical presentations. Complete surgical resection either via open or endoscopic endonasal approaches are the main mode of treatment. Here, we report a series of 5 cases of clival chordomas which was managed via endoscopic endonasal approaches in our center. A retrospective analysis of patients who had undergone endoscopic endonasal resection of clival chordoma in Sarawak General Hospital from 2014 to 2018. A total of 5 cases were operated on endoscopically via a combine effort of both the otorhinolaryngology team and the neurosurgical team during the study period from year 2013 to 2018. From our patient, 2 were female and 3 were male patients. The main clinical presentation was headache, squinting of eye and nasopharyngeal fullness. All our patient had endoscopic endonasal debulking of clival tumor done, with average of hospital stay from 9 - 23 days. Pos-operatively, patients were discharged back well. Endoscopic endonasal resection of clival chordomas gives good surgical resection results with low morbidity rates and therefore can be considered as a surgical option in centers where the surgical specialties are available.

Adenoid Cystic Carcinoma of the Nasopharynx: A Case Series.

Adenoid cystic carcinomas are tumors that are more commonly seen in the salivary glands than in the nasopharynx. Nasopharyngeal adenoid cystic carcinomas are rare and cases that are reported in the literatures are few. Treatment is mainly by surgical resection. Here, we report 2 cases of nasopharyngeal adenoid cystic carcinoma.

Laryngeal Leiomyosarcoma: A Rare Case.

Laryngeal leiomyosarcoma is a rare smooth muscle malignancy of the head and neck region. Diagnosis is based on immunohistochemistry. Here we present a case of laryngeal leiomyosarcoma that was diagnosed and treated in our center, focusing on the clinical features, histological diagnosis and management of this rare disease.
