  • In disease diagnostics and health surveillance, the use of saliva has potential because its collection is convenient and noninvasive. Over the past two decades, the development of salivary utilization for the early detection of cancer, especially oral cavity and oropharynx cancer has gained the interest of the researcher and clinician. Until recently, the oral cavity and oropharynx cancers are still having a five-year survival rate of 62%, one of the lowest in all major human cancers. More than 90% of oral cancers are oral squamous cell carcinoma (OSCC). Despite the ease of accessing the oral cavity in clinical examination, most OSCC lesions are not diagnosed in the early stage, which is suggested to be the main cause of the low survival rate. Many studies have been performed and reported more than 100 potential saliva biomarkers for OSCC. However, there are still obstacles in figuring out the reliable OSCC salivary biomarkers and the clinical application of the early diagnosis protocol. The current review article discusses the emerging issues and is hoped to raise awareness of this topic in both researchers and clinicians. We also suggested the potential salivary biomarkers that are reliable, specific, and sensitive for the early detection of OSCC.

  • Myxomas can be divided into two groups: those derived from the facial skeleton, and those derived from external skeletal soft tissue. Soft tissue myxomas of the head and neck are uncommon, with fewer than 50 cases reported. In any form and location, myxoma of parotid gland is rare. We report a case of myxoma arising from the left superficial lobe of the parotid gland with good long-term follow-up after superficial parotidectomy with tumor excision. A 49-year-old man was referred to our department of plastic and reconstructive surgery with a painless palpable mass that had persisted in the left mandible angle region for 2 years. Excision of the facial mass and superficial parotidectomy with facial nerve preservation were performed. The biopsy result was myxoma. Long-term follow-up for 22 months showed favorable results without evidence of recurrence but with temporary facial nerve weakness right after the surgery. Myxoma should be considered as a differential diagnosis when benign tumor of the parotid gland is being considered.

  • A lipoma is a benign tumor of matured adipose tissue that usually occurs at the shoulder, back, and abdomen. 13% of lipomas occur in the head and neck area. However, the incidence of lipoma in the parotid gland is very low, approximately 2.5%. A conservational surgical excision is recommended in cases of lipoma of the parotid gland, with only 1-2% of lipomas recurring. We report a case of a lipoma in the parotid gland that was removed by conservational surgical excision. The lesion was exposed by the pre-auricular approach and the tissue was detached. After the parotid gland envelop was exposed, a yellowish mass is observed that was easy to remove due to capsulation. Most authors recommend a surgical excision of the superficial lobe of the parotid gland as the treatment for a lipoma in the parotid gland. However, enucleation only may be a sufficient treatment when a lipoma occurs in the superficial lobe or around the parotid gland. A patidectomy is not needed when a lipoma is located at the superficial lobe of the parotid gland, and a conservational surgical excision is suitable. Therefore, a clinical diagnosis is important for reducing the damage to the facial nerve.

  • Nasopharyngeal carcinoma (NPC) is the second most common neoplasm of head and neck in Tunisia. The distribution is bimodal with a first period occurrence between 15 and 20 years old and a second peak at around 50 years of age. Undifferentiated carcinoma of nasopharynx type III (UCNT) is the predominant histological type (93.4%). Data of cancer registry of North Tunisia confirmed that it is an intermediate risk area for NPC with overall ASRs of 3.6 and 1.6/100,000 respectively in males and females. This study aimed to present the evolution of incidence rate of nasopharyngeal carcinoma over a period of 12 years (1994-2006). Data of cancer registry of North Tunisia (NTCR), covering half of the Tunisian population, were used to determine evolution of NPC incidence, calculated by 5 year periods. The estimated annual percentage change (EAPC) was used as an estimate of the trend. To best summarize the behavior or the data trend across years, we used a join-point regression program. Between 1994 and 2006, we observed negative annual average change of standardized incidence in men and women (-3.3%and -2.7%) also for the standardized incidences which showed a rather important decline (26.4% in males and 22.3% in females). The truncated age standardized incidence rate of NPC in adults aged of 30 years old and more (N= 1209) decreased by -0.4% per year from 1994 to 2006 over time in north Tunisia dropping from 6.09 to 4.14 person-years. However, the rate was relatively stable during this period among youths aged 0-29 years (N= 233) in both sexes. NPC demonstrated a favorable evolution from 1994-2006 probably due to a improvement in socioeconomic conditions.

  • Plasmacytoma is a rare malignant neoplasm in the head and neck region and comprises approximately 3% of all plasma cell tumors. This lesion is a unifocal, monoclonal, neoplastic proliferation of plasma cells that usually arises within the bone. Infrequently, it is observed in soft tissue, in which case, the term extramedullary plasmacytoma is used. Approximately 80-90% of extramedullary plasmacytomas involve the mucos-Associated-Lymphoid Tissue of the upper airways with 75% of these involving the nasal and paranasal regions. The plasmacytoma is usually detected in adult males, with an average age at diagnosis of 55 years. The male-to-female ratio is 3:1.Radiographically, the lesion may be seen as a well-defined, unilocularradioluceny with no evidence of a sclerotic border. Some investigators believe that this lesion represents the least aggressive part of the spectrum of plasma cell neoplasms that extend to multiple myeloma.Therefore, plasma cytoma is believed to have clinical importance. We report a case of extramedullary plasmacytoma in the right maxillary sinus of a 59-year-old male with review of the relevant literature.

  • Fine needle aspiration cytology has become a frequently used technique for the diagnosis of lesions in the head and neck. Fine needle aspiration cytology of the salivary glands were performed on 66 patients. In 59 patients with satisfactory samples, cytologic diagnoses were as follows; there were 47 benign lesions, including pleomorphic adenoma(20), Warthin's tumor(3), benign cystic lesion(4), Inflammatory lesion(4), lymphoid lesion(3), myoepithelioma(1), unspecified benign neoplasm (5), and unclassified benign lesion(7). There were 6 cases of undetermined malignancy and 6 malignant lesions including mucoepidermoid carcinoma(3), adenoid cystic carcinoma(1), carcinoma ex pleomorphic adenoma(1), and metastatic carcinoma(1) in cytologic diagnosis. In 25 patients, the cytologic diagnosis was correlated with histologic findings. The sensitivity of the benign lesion was 96% and the specificity was 82%. There was no false-positive diagnosis. The sensitivity and the specificity of pleomorphic adenoma were 75% and 95%, respectively. Some of Warthin's tumors were confused with benign cystic lesion due to frequent cystic change of the tumor. The sensitivity and specificity of the malignant lesions were 56% and 88%, respectively. There were three false negative diagnoses. Two mucoepidermoid carcinomas were correctly diagnosed by cytology. Two of three adenoid cystic carcinomas were misdiagnosed as benign tumors.

  • Atypical fibroxanthoma is a pleomorphic spindle cell neoplasm characterized by a variable combination of cells with fibroblastic and histiocytic features. It occurs mostly on sun-exposed area of the head and neck of elderly person and is a clinically benign reactive lesion despite apparent malignant histologic features. However, because of its potential for metastasis, it is widely regarded as a low-grade sarcoma. We report a 30-year-old woman with atypical fibroxanthoma developed on the left occipital area. The lesion was $1.5{\times}2cm$ sized papule. There was no skin lesion such as ulcer or eschar. However, mass was involving occipital bone and composed of dense, pleomorphic spindle cells and several bizarre multinucleated giant cells. After wide excision of the scalp and occipital bone, the defect was covered with bone cement, bipedicled local flap and the donor site was covered with STSG. The wound healed completely without complication. It remained free of recurrence for a period of about 1 year follow up.

  • 측두하악장애 증상으로 나타나는 구강안면부의 통증 및 개구제한 증상은 대부분 관련 구조물 자체의 구조적이거나 기능적인 변화에 의해 유발되지만, 드물게 다른 병적인 상태로 인하여 발생할 수도 있으므로 진단 및 치료에 있어서 주의가 요구된다. 특히 통증 양상 및 임상 소견, 전신적 동반 증상, 치료에 대한 반응 등에 대한 평가에서 두경부 종양과 같이 다른 질환에 의한 측두하악장애 증상이 의심되거나 일반적인 측두하악장애와 다른 소견이 나타나는 경우에는 전산화단층촬영 또는 자기공명영상 등의 부가적인 방사선학적 검사를 적극적으로 시행하여 부가적인 정보를 얻는 것이 필요하다. 본 증례에서는 측두하악장애 증상으로 내원하였던 비인두암종 환자의 진단 및 치료 과정을 통해, 측두하악장애의 진단 및 치료에 있어서 비인두암종 등 두경부 종양의 가능성을 고려해야 할 임상적 소견에 대해 고찰하고자 한다.

  • 1859년 Billroth가 부비동에 발생한 종양을 "Zylindrome" 이라고 처음 명명한 이후 cylindroma, basaloma, basaloid adenoma, cribriform adenocarcinoma등으로 일컬어져 왔다. 그러나 최근에는 adenoid Cystic carcinoma라고 널리 사용되고 있다. 이 종양은 주로 두경부의 타액선에서 발생하고 있으나 그외 기관, 폐, 유방, 피부 등에서도 드물게 생긴다고 한다. 이 종양은 근치수술과 같은 광범위한 외과적 절제후에도 국소재발이나 원격전이가 많으며 방사선 치료로서 완전치유는 불가능 하나 종양의 축소와 동통의 소실등 경감치료에 좋은 효과를 보여 주는 것이 그 특징이다. 저자들은 1963년 1월부터 1980년 l2월까지 전주 예수병원에서 진단받은 adenoid cystic carcinoma 44례에 대하여 분석 검토하여 다음과 같은 결과를 얻었다. 1) 동기간의 두경부 악성종양중 3.8%를 차지하며 타액선 악성종양중 40%였었다. 2) 가장 흔한 원발장소는 구개, 악하선으로 각각 8례이며 그외 상악동이 6례 비강이 5례, 이하선, 설부위가 각각 4례였다. 3) major gland가 13례(31%), minor gland가 29례 (69%)였 다. 4) 성별은 남자 21례, 여자 23례로 남여의 차이는 거의 없었다. 5) 연령빈도는 19세에서 78세 사이로 평균 연령은 50세 였다. 6) 초친시 종양의 크기는 4∼6cm가 10례로 가장 많으며 임상적 경부 임파전이가 7례, 원격전이가 1례 였다. 7) 27례에서 근치수술을 시행 하였으며 이 중 14례는 수술과 방사선 병용 요법을 시행하였다. 8) 추적 관찰이 가능 하였던 29례에서 gross 3-year survival은 27.6%, determinate 3-year survival은 44.4%였다. 이 중 근치수술 받은 12례 있어서 3-year survival rate는 58%였다. 9) 29례중 10례에서 치료후 국소 재발을 보였다. 치료와 국소 재발 간의 기간은 3개월에서 88개월이며 이중 3례는 5년 이후였다. 10) 치료후 원격전이를 보인 것은 3례이며 전이장소는 모두 폐 였다.
