Abstract
BACKGROUND Head and neck neoplasia constitute one of the commonest cancers in India. Use of smokeless tobacco (Pan masala, Zarda etc.) is on the increase in North India, especially in Uttar Pradesh, and is responsible for the large majority of these tumours. AIM To assess the patients' characteristics, yearly prevalence and histopathological subtypes of the head and neck neoplasia (excluding oral cavity) in Allahabad and surrounding regions. SETTINGS AND DESIGN A retrospective study of 11 years from 1990 to 2000 was designed. Data was collected year-wise using the tumor registry data. MATERIAL AND METHODS All biopsies submitted for histopathology to the Pathology department were reviewed and analyzed for demographic data, site and diagnosis. STATISTICAL ANALYSIS The Kolmogorov-Smirnov Two-Sample Test was utilized to determine whether two distributions are the same. RESULTS A total of 40559 biopsies were examined in the department, of which, lesions of the head and neck region, excluding the oral cavity, constituted 694 biopsies (409 males and 285 females). One hundred and forty-four malignant lesions were reported, 114 being males and 30 females. A comparison of the age-specific prevalence rates of cancer during the study period showed that the prevalence was highest in patients belonging to the 50-59 years age group and squamous cell carcinoma Grade II was the most prevalent type. On an average, 58 new biopsies per annum were received. CONCLUSIONS Properly structured site-specific data like this can augment the National Cancer Registry Programme and is an essential indicator for the magnitude and the pattern of the cancer problem in India.

Abstract
BACKGROUND Burkitt's lymphoma is endemic in Nigeria; it forms about 39% of all childhood cancers. In recent times more of these cases are being seen presenting first to the Ear Nose and Throat clinic. OBJECTIVE This study is designed to look at the pattern of presentation of head and Neck Burkitt's lymphoma at a Nigerian Tertiary hospital and to evaluate current treatment modality. DESIGN It is a retrospective study of all confirmed Burkitt's lymphoma of the head and neck region seen at the Obafemi Awolowo University Teaching Hospital Ile Ife (OAUTHC) between 1986 and 2002. PATIENTS AND METHODS The medical records of all the patients with the histopathologically confirmed Burkitt's lymphoma over a 17-year period (1986-2002) were evaluated. The proportion of the tumor affecting the Head and neck region were noted. The data extracted were entered into a questionnaire and analysis of data was done using the SPSS 10.0 software. RESULTS A total of 196 cases of Burkitt's lymphoma were seen over the period out of which 140 (71.4%) were in the head and neck region. There was a male preponderance with the incidence of 72% and 28% in females. The peak age incidence was found to be within the first decade of life. The most common sites that were affected are; the jaw (65.9%), nasal and paranasal sinuses (12.2). Majority of the patients presented with advanced disease. Combination Chemotherapy comprising Cyclophosphamide, Oncovin, Methotrexate and Prednisolone (COMP) was the mainstay of management. The treatment outcome was only favorable in 36.6%. Default rate was (11.7%) while the mortality rate was (12.6%). Relapse\recurrence was found in (5.1%) of cases. Frank drug resistance was found in (2.6%). Blindness was found to be a major morbidity associated with this disease. Septicemia and severe anemia were found to be the major causes of mortality. Some complications of treatment were noted. DISCUSSION The importance of the findings in this work was discussed in line with the existing literature. CONCLUSION Head and neck remain the mostly affected parts in Burkitt's lymphoma in this environment. Presentation with advanced disease is the bane. This partly explains high morbidity and mortality in affected children.

Abstract
AIMS To present the first cross-culture validation of the European organization for research and treatment of cancer (EORTC) quality of life questionnaires, the EORTC-QLQ-C30, and the QLQ-H&N 35 in India. SETTINGS AND DESIGN These questionnaires were translated into two vernacular languages and pilot test was done on 15 patients. Two hundred head and neck cancer patients completed the QLQ-C30 and the QLQ-H&N 35 at two time points during their treatment. Psychometric evaluation of the structure, reliability, and validity of the questionnaire was undertaken. RESULTS The data supports the reliability of the scales. Validity was tested by item-scale, scale--scale correlation and by performing known group comparisons. The results demonstrated that the items correlated with their respective scale and no significant correlation was found between scales. The questionnaire was responsive to change over a period of time. SUMMARY This data suggests that the EORTC QLO-C30 and the QLQ-H&N 35 are reliable and valid questionnaires when applied to a sample of head and neck cancer patients in India.

Abstract
PURPOSE OF REVIEW Aerodigestive (lung, head and neck) cancers are among the most prevalent and deadly neoplasms worldwide, and the incidence rates are rising. Given the improvements in life expectancy of persons with HIV/AIDS when treated with highly active antiretroviral agents, persons with HIV infection are therefore increasingly likely to develop these malignancies. This chapter focuses on the epidemiology of these malignancies and reviews the most recent literature and current understanding of the causes and treatment of these malignancies in HIV-positive populations. RECENT FINDINGS Aerodigestive neoplasms in patients with HIV infection are associated with younger age at diagnosis, cigarette smoking, advanced stage at presentation, and a more aggressive clinical course. The causes of these cancers, aside from the traditional risk factors of tobacco and alcohol exposure, are not clear. Although these neoplasms are non-AIDS defining, factors that might contribute to risk include HIV-related immunosuppression and co-infection with high-risk human papillomavirus subtypes. SUMMARY With continued improvements in therapies for HIV, the expected increase in incidence and mortality of persons with HIV infection from aerodigestive malignancies will likely become a major public health concern. Given the younger age of HIV-infected patients with these malignancies and the apparently higher rates of smoking among HIV-positive individuals, aggressive smoking cessation efforts should be directed to this high-risk population.

Abstract
The term "head and neck cancer" has been widely adopted in the recent literature, to include the lesions at several anatomic sites: the lip, oral cavity, nose and para-nasal sinuses, naso-pharynx, oro-pharynx, hypo-pharynx, and larynx. In this communication, the data on human papillomavirus (HPV) involvement in oral, oro-pharyngeal, sino-nasal, and laryngeal carcinomas are reviewed. Our group was the first to present evidence on the involvement of HPV infections in both laryngeal and oral carcinogenesis, prompted by the discovery of morphological similarities between oral and cervical squamous cell lesions. The latest meta-analyses of the epidemiological studies as well as the multi-centre case-control studies have confirmed HPV as an independent risk factor for oral cancer, with a range of odds ratios (OR) between 3.7 and 5.4. Until 2002, 4768 oral carcinomas have been analysed for HPV DNA, and 22% were reported to contain HPV by any of the detection techniques. Of all non-genital cancers, tonsillar carcinomas appear to have the highest prevalence of HPV. By the end of 2002, 422 cases of tonsillar carcinoma have been analyzed for the presence of HPV DNA, with the overall detection rate of 51%. HPV 16 is the most prevalent HPV type found in 84% of HPV DNA-positive tumours. HPV seems to be mainly episomal in tonsillar carcinomas, but the significance of this observation is still obscure. Interestingly, patients with HPV 16-positive tumours seem to have a better overall- and disease-specific survival, as compared with the HPV-negative group. To date, 1041 sino-nasal papillomas have been analysed for HPV and 347 (33%) cases have been positive, whereas of the 322 sino-nasal carcinomas analysed so far, 70 (22%) have been positive for any HPV type. Laryngeal squamous cell papilloma and recurrent respiratory papillomatosis (RRP) are well-established HPV-induced tumours, whereas the role of HPV in laryngeal carcinomatosis remains controversial. The molecular mechanisms of HPV-associated carcinogenesis of the head and neck require further study.

Abstract
Tobacco exposure is a key risk factor for head and neck cancer, and continued smoking after diagnosis negatively affects outcomes. The present study examined tobacco smoking, nicotine dependence, alcohol use, and depression in survivors of head and neck cancer. Subjects at least 6 months post-initial diagnosis of head and neck cancer (N=694) drawn from three VA otolaryngology clinics (n=309, VA patients) and a university-based otolaryngology clinic (n=385, non-VA patients) were administered questionnaires and standardized rating instruments for nicotine and alcohol dependence and for depression. Additional clinical information was extracted from chart reviews. Despite high rates of prior smoking, less than one-quarter of all subjects continued to smoke. After controlling for significant confounding variables, we found that VA patients were more likely to be current smokers (OR=1.9, 95% CI=1.3-3.0), but current VA smokers did not differ significantly from non-VA smokers on the Fagerström Test for Nicotine Dependence criterion (p=.69). The VA patients were more likely to screen positive for problem drinking on the Alcohol Use Disorder Identification Test (OR=2.1, 95% CI=1.3-3.7). After adjusting for other variables, we found no statistical difference between the groups in depression scores on the Geriatric Depression Scale-Short Form. The study provides data on smoking, alcohol use, and depression in head and neck cancer survivors indicating that VA patients are at increased risk for continued smoking and problem drinking relative to non-VA patients. Head and neck cancer patients benefit from aggressive smoking cessation efforts by the VA, but many patients need specialized services that integrate smoking interventions with treatment of comorbid alcoholism.

Abstract
PURPOSE Description of clinical and epidemiological characteristics of patients who underwent surgery for oral cancer in a Medical School Teaching Hospital, and determination of differences with respect to other institutions and/or periods of time. METHOD The charts of patients undergoing surgery for oral cancer from 1994 to 2002 were reviewed. Data were collected in a spreadsheet in order to analyze clinical and epidemiological features.. RESULTS A total of 374 patients having undergone 406 operations was identified. Their ages varied from 14 to 94 years (mean = 57.4 years), with 255 men (68.2%), and 295 out 366 Caucasian (80.6%). A majority had tumors of the tongue and/or floor of mouth (55.6%), while 20.3% had lip cancer. Squamous cell carcinoma was found in 90.3%, and glandular carcinoma in 4%. T4 tumors in 39.6%, Tis or T1 lesions in 15.2% of all patients. Nearly 62% had no regional metastases, and the relative incidence in young patients (40 years or younger) reached 8.6%. CONCLUSION In spite of the predominance of locally advanced tumors, a majority of patients had no neck metastases. The 31.8% incidence in females indicates an increasing incidence of oral cavity cancer among women when compared to previous periods at the same institution.

Abstract
PURPOSE OF THE REVIEW Squamous cell carcinoma of the upper aerodigestive tract most commonly develops in the sixth or seventh decade of life, usually in patients who have significant risk factors from smoking or alcohol use. A subgroup of patients less than 45 years old, however, develops squamous cell carcinoma of the head and neck in whom the role of tobacco or alcohol use is less clear in the etiology of their cancer. Furthermore, there has been considerable debate regarding the tumor biology in this group of patients and its effects on prognosis and overall survival. This paper reviews the current literature and controversies on the etiology and management of squamous cell carcinoma of the head and neck in young patients. RECENT FINDINGS Young patients with head and neck squamous cell carcinoma do not have a poorer prognosis or disease-specific survival. SUMMARY Young patients with squamous cell carcinoma of the head and neck have a similar prognosis to older patients. There is a trend, however, towards a higher regional recurrence in young patients with head and neck squamous cell carcinoma, suggesting that prophylactic neck treatment should be considered. Further research is needed to determine whether a subgroup of patients (young nonsmoking women with tongue cancer) have a worse prognosis and warrant more aggressive treatment.

Abstract
A retrospective, cross sectional, series of cases were currently studied in the department of ENT-Head & Neck Surgery of Tribhuvan University Teaching Hospital (TUTH) Kathmandu, Nepal to find out the distribution of different malignancies in head and neck regions and to identify their treatment modalities during the period of one year from January 2003 to December 2003. Altogether 159 new cases of histopathologically/cytopathologically confirmed malignancies of head and neck regions and their treatment modalities were analyzed. Out of 159 cases, malignancies of larynx (41), pharynx (31) and oral cavity (30) were found to be the commonest head and neck malignancies where as malignancies of ear (1), and salivary glands (4) were found to be the least common. Likewise surgery with or without radiotherapy and/or chemotherapy was found to be the commonest treatment modality. Of the 159 cases seven were occult primary. As the laryngo-pharyngo-oral malignancies are the commonest malignancies and surgery with or without radiotherapy and/or chemotherapy the commonest treatment modalities for these head and neck malignancies. A well equipped head and neck unit is needed at TUTH along with proposed radiotherapy and medical oncology support for better management of these malignancies.

Abstract
OBJECTIVE To study the clinical presentations, diagnosis and management of patients with the pathological diagnosis of branchial cysts. METHODS This was a retrospective analysis of the records of 33 patients with the diagnosis of branchial cyst, seen between 1987 and 2003 at the General Surgical Unit of Jordan University Hospital. RESULTS Thirty-four cases of branchial cysts were seen in 33 patients: 22 females and 11 males. There was a wide range in age (1-57 years), but the majority (25 patients) were in their second or third decades of life. Thirty-one cysts occurred in the classical site. The same number of branchial cysts occurred on the right and left sides of the neck (17 on the right and 17 on the left). Correct clinical diagnosis was made in only 14 cases (41.2%). CONCLUSION Branchial cysts are frequently incorrectly diagnosed and forgotten in the differential diagnosis. Thus, the diagnosis is often delayed, resulting in the mismanagement of these patients. Branchial cyst should be suspected in any patient with a swelling in the lateral aspect of the neck, regardless of whether the swelling is solid or cystic, painful or painless. Fine needle aspiration cytology will accurately demonstrate the cystic nature. The presence of cholesterol crystals and/or epithelial cells in the aspirate will suggest the diagnosis of branchial cyst.

Abstract
Angiosarcoma of the head and neck is a rare and lethal neoplasm. Data from the Connecticut Tumor Registry was analyzed for all head and neck angiosarcomas between 1980 and 2001. The authors also present the first reported case of familial angiosarcoma of the head and neck region. The 1-year mortality was 48% for all patients with angiosarcomas (38% for males, 69% for females). The 5-year survival was 28% for all patients (38% for males, 15% for females). The combination of surgery and radiotherapy resulted in improved survival compared with either treatment alone.

Abstract
Head and neck cancer comprises squamous cell carcinomas of the upper aerodigestive tract. There are similarities in their natural history, epidemiology and control. For these cancers premalignant changes can be identified. Smoking and drinking are the major risk factors. The geographical variations in incidence and mortality are indicative of differences in the prevalence of risk factors between countries. The dramatic increase in head and neck cancers is cause for great concern, particularly in Central-Eastern Europe. The great majority of these cancers could be prevented by reducing the prevalence of established risk factors. Screening could be used to detect both precancerous lesions and early invasive cancers; however, no study as yet has demonstrated a reduced incidence and mortality resulting from screening. When setting strategies for prevention, the socioeconomic differentials in incidence and mortality from head and neck cancers need to be taken into account.

Abstract
The existence of branchiogenic carcinoma remains controversial. According to some authors, this malignancy is more conceptual than a true clinicopathologic entity. The originally proposed diagnostic criteria of branchiogenic carcinoma have been subsequently challenged. Many reports regarding primary branchiogenic carcinoma have failed to provide sufficient evidence to distinguish this entity from nodal metastases arising from unrecognized primary tumours. There is growing evidence that the majority of branchiogenic carcinomas are in fact cystic metastases from oropharyngeal carcinoma, most commonly originating in the tonsils, and not true carcinomas arising in a branchial cleft cyst. The missing link between branchial cyst and branchiogenic squamous cell carcinoma could be fulfilled by the occurrence of in situ branchial cyst carcinomas, yet such cases are extremely rare. Isolated cystic neck lesions, necessitate a thorough search for a primary tumour, similarly to other occult primaries presenting with cervical metastases. The treatment of cervical cyst with dysplasia or carcinoma in situ includes complete surgical excision. The true branchiogenic carcinomas should be approached with postoperative irradiation to the half neck. A cervical metastatic cystic squamous carcinoma of unknown origin should be treated as for other cases of occult primaries, i.e. with surgery and radiotherapy. The data on the prognosis of branchiogenic carcinoma are scarce, though long-term survival has been reported. Further histopathologic and clinical studies are warranted in order to better understand the biology and natural history of cervical cystic lesions. The existence of true branchiogenic carcinoma remains to be verified with new clinical and molecular criteria.

Abstract
Lymphomas of the head and neck arise in lymph nodes and extranodal areas as Waldeyer ring, nasal cavity, thyroid gland and salivary glands. Though anatomically in close proximity, lymphomas presenting at the ENT area have different clinical characteristics if they are Hodgkin or Non-Hodgkin. We included 31 patients with the diagnosis of lymphoma and diagnosed in our Department between 1999 and 2002. We studied all the different variables that differentiate Hodgkin and Non-Hodgkin's lymphoma. Both types of lymphoma usually present as a cervical mass. Non-Hodgkin lymphoma have extranodal involvement more frequently and also a more advance disease at diagnosis. It is important to include the lymphoma in the differential diagnosis of any cervical mass or ENT lesion.

Abstract
On the basis of an inception cohort of 270 patients with a previously untreated invasive squamous cell carcinoma of the true vocal cord (232 T N0M0, 35 T2N0M0, and 3 T3N0M0) and a minimum of 3 years of follow-up, the authors analyze the oncological and functional outcomes following frontolateral vertical partial laryngectomy without tracheotomy. The 5-year Kaplan-Meier actuarial survival estimate ranged from 83.1% for T1 tumors to 67.2% for T2 tumors (p = .005). On univariate analysis, a significant statistical relationship was noted between reduced survival and the following variables: increased age, increased Charlson comorbidity index score over grade 0, increased tobacco intake, increased alcohol intake, increased T stage, local failure, nodal failure, and development of a metachronous second primary cancer. The hospital mortality rate was 0.4%. A significant postoperative surgical complication was noted in 49 patients (18.1%). The predominant significant surgical complication was wound infection (19 patients; 7%), followed by seroma and major subcutaneous emphysema. No significant statistical relationship was noted in a comparison of each, significant postoperative complication (including postoperative death) with the variables under analysis. The incidence of secondary tracheotomy was 0.4%. The incidence of completion laryngectomy due to functional problems was 0%. The 5-year Kaplan-Meier actuarial local control estimate was 91% for T1 tumors and 68.7% for T2 tumors (p <.0001). Within the T1 tumors, the 5-year Kaplan-Meier actuarial local control estimate ranged from 96.2% for tumors without anterior commissure involvement to 74.7% for tumors with anterior commissure involvement (p = .0002). On univariate analysis, a significant statistical relationship was noted between an increase in local recurrence and the following variables: increased T stage, anterior commissure involvement, and pathological margin involvement. The overall disease control rate and laryngeal preservation rate were 92.9% and 93.3%, respectively.

Abstract
OBJECTIVE To elaborate the relationship between obstructive sleep apnea (OSA) and head and neck neoplasms (HNN). STUDY DESIGN AND SETTING A systematic review of the MEDLINE literature. RESULTS Thirty of 34 articles indexed under OSA and HNN were about neoplasms that presented first as OSA. Four of the articles were about treatment of HNN causing OSA and gave incidences varying from 8% to 92%. Quality of life surveys confirm that patients with malignant HNN have sleep problems. Xerostomia may contribute to these sleep problems, and the role of salivary mucins deserves consideration. CONCLUSIONS This review of the literature raises several new research questions about the clinical and biological relationships between OSA and HNN.

Abstract
One of the most troublesome failures in head and neck tumors treatment is the incidence of multiple primary tumors (MPT). The aim of the study was to identity the genetic factors associated with the predisposition of second cancer occurrence. The polymorphisms of genes involved in carcinogen metabolic activation (CYP1A1, CYP2E1), detoxication (GSTM1, GSTT1, GSTM3, NAT2,) and DNA repair (XPD /A35931C-exon 23 and C22541A-exon 6/, XRCC1 /G28152A-exon 10 and C26304T-exon 6/, XRCC3/C18067T/) were studied by PCR-based techniques to analyze genotypes and allele distribution in 84 patients with MPT correlated with 182 subjects with a single tumor of head and neck and 143 cancer-free male volunteers recruited from healthy smokers. Out of 11 polymorphisms examined significant differences between studied groups in CYP1A1, GSTM1, NAT2 genes, but not at the CYP2E1, GSTT1, GSTM3, XPD (exon 23 and 6), XRCC1 (exon 10 and 6) and XRCC3 were established. Further, the coexistence of some genotypes/alleles associated with a higher cancer risk, so called 'risk genotypes' was established as an added genetic factor to MPT development. The interpretation of our data indicates that the same group of low-penetration genes is involved in the development of single and multiple primary head and neck cancer but their association with MPT is significantly stronger.

Abstract
This study evaluated cytogenetic damage by measuring the frequency of micronucleated cells (MNC) in peripheral blood and buccal mucosa of head-and-neck cancer patients undergoing radiotherapy. MNC frequencies were assessed in 31 patients before, during, and after radiotherapy, and in 17 healthy controls matched for gender, age, and smoking habits. Results showed no statistically significant difference between patients and controls prior to radiotherapy in cytokinesis-blocked lymphocytes or buccal mucosa cells. During treatment, increased MNC frequencies were observed in both cell types. Micronucleated lymphocyte levels remained high in samples collected 30 to 140 days after the end of treatment, while MNC frequency in buccal mucosa decreased to values statistically similar to baseline values. There is controversy over the effects of age, smoking habit, tumor stage, and/or metastasis on MNC frequency. However, increased frequency of micronucleated buccal mucosa cells was seen in patients under 60 years old and in those with tumors >4 cm. In conclusion, the data show that radiotherapy has a potent clastogenic effect in circulating lymphocytes and buccal mucosa cells of head-and-neck cancer patients, and that the baseline MNC frequency in these two tissues is not a sensitive marker for head-and neck neoplasm.

Abstract
INTRODUCTION In the industrialized nations of the Western hemisphere the age group beyond 75 years will grow steadily, requiring special attention by medical professionals in the future. With regard to these expectations 40 patients, beyond the age of 75 and who were first diagnosed to suffer from squamous cell carcinoma of the upper aerodigestive tract, were analysed. MATERIAL AND METHODS Forty patients diagnosed and treated between 1998 and 2003 for head and neck squamous cell carcinoma (HNSCC) were analysed. RESULTS Laryngeal carcinoma was noted in 80% of the patients. All types of treatment were tolerated well. Patient compliance was generally good and the rate of complications was low. CONCLUSION The results of the present study show that HNSCC in elderly patients should be treated with curative intention. Age itself should never be a sole factor in deciding which curative therapy should be undertaken. Exceptions could be made in patients with severe general comorbidity.

Abstract
We have prepared the map of regional distribution of cervical cancer in Hungary. Serial HPV genotyping of sexual partners provided evidence for the sexually transmitted infections. Molecular epidemiology studies revealed activating c-kit mutation in bilateral testicular cancers. A cost-effective molecular staging method was introduced to the management of breast cancer patients. Genomic profiling identified the gene signature of Herceptin and taxane sensitivity of breast cancer. In colon cancer patients we have determined the mutational spectrum of hMLH1 and hMSH2 genes in Hungary. The prognostic power of SHMT and MTHFR polymorphism was determined in colorectal cancer patients. In head and neck cancer the gene signature of cisplatin sensitivity and the EGFR polymorphism was determined. We have introduced a cost-effective in vitro assay to determine the drug resistance of pediatric leukemias. The prognostic power of N-myc genotyping was determined in neuroblastoma patients. A phase I trial for gene therapy of brain cancer was started by using a GM-CSF adenoviral vector system. Using global genomic approaches the gene signature of malignant melanoma and its metastatic disease was determined. We have found that Ca-channel blockers and EGFR tyrosine kinase inhibitors are effective in preclinical human melanoma models in breaking the apoptosis resistance of this tumor.

Abstract
The incidence of multiple primary carcinomas (MPCs) associated with esophageal cancer has increased. The purpose of this study was to analyze clinicopathologic findings for MPC and for only esophageal cancer (OEC). Of 157 patients with MPCs, 60 had synchronous cancer and 97 metachronous cancer. Another 42 patients had antecedent esophageal cancer (AEC), and 55 patients had subsequent esophageal cancer (SEC). We retrospectively analyzed the clincopathologic findings for patients in these categories. The incidence of early-stage carcinoma was higher in patients with MPCs than in those with an OEC. Of patients with MPCs, those with metachronous cancer had a higher rate of early-stage carcinoma than those with synchronous cancer. The 5-year survival rates were not significantly different for MPC and OEC patients. Patients with metachronous cancer had a significantly better prognosis than those with synchronous cancer (p = 0.017); and in the metachronous cancer group the prognosis was significantly better for patients with AEC than for those with SEC (p = 0.0005). Meticulous follow-up after treatment of a first cancer should be required to detect other early-stage carcinomas.

Abstract
It has been hypothesized that cutaneous melanoma at different anatomic sites develops through divergent pathways. We examined this hypothesis prospectively. We followed 152,949 women and 25,204 men free of cancer at baseline for up to 14 years in three large prospective studies. We examined risk factors for melanoma by anatomic location (head or neck, trunk, upper extremity, and lower extremity). Polytomous logistic regression was used to test the difference among risk factors by location of melanoma. A total of 511 incident cases of invasive melanoma (49 head or neck, 188 trunk, 98 upper extremity, and 176 lower extremity) were included in the analysis. Compared with females, males had a higher risk of developing melanoma on the head or neck and trunk. History of severe and painful sunburn was most strongly related to melanoma of upper extremity; individuals with >10 burns had a 6.86-fold (95% confidence interval, 2.62-18.00) higher risk of melanoma of upper extremity compared with those with no burns (P for trend < 0.0001; P for difference by body site = 0.04). Number of moles was most strongly related to melanoma of the trunk; the multivariate relative risk for having >10 moles was 4.67 (95% confidence interval, 3.07-7.11) compared with having no moles (P for trend < 0.0001; P for difference by body site = 0.04). Age, family history of melanoma, and hair color did not statistically differ by anatomic site of the cancer. These data support divergent etiologic pathways of melanoma development by anatomic sites.

Abstract
This article reviews the clinical characteristics, histology, biologic behavior, and recommended treatment for several benign and malignant lesions that may arise on the head and neck. Nevus sebaceus and congenital melanocytic nevus are two benign lesions that can present at a size of several centimeters. Surgical excision may be considered for cosmetic purposes and to reduce the small risk for the development of malignancy within each lesion. Basal and squamous cell carcinoma, lentigo maligna and lentigo maligna melanoma, dermatofibrosarcoma protuberans, and Merkel cell carcinoma are malignant lesions for which surgical excision is the recommended treatment. Local flap reconstruction may be used to address the surgical defects resulting from excision of these benign and malignant conditions.
