Rhabdomyosarcoma is an aggressive malignant tumor rarely developing in the head and neck in adults. In the sinonasal region, rhabdomyosarcoma constitutes a clinically important group because of the difficulty of surgical resection and its generally poor prognosis. Inverted papilloma is a relative rare and benign sinonasal lesionconstituting 0.5% to 4% of all nasal tumors that has a known propensity for recurrence, local aggressiveness, and association with transformation to malignancy. Squamous cell carcinoma is the major malignancy that is associated with inverted papilloma. To our knowledge, this is the first case report of pleomorphic rhabdomyosarcoma accompanied with inverted papilloma, and we represent the case with a review of the related literatures.

Sinonasal inverted papilloma (SNIP) is one of the most common benign sinonasal tumors demonstrating a high recurrence rate after surgery, and sometimes presents malignant tendency or coexists squamous cell carcinoma. Therefore, it is essential to achieve complete surgical resection, especially the original location of SNIP. In this paper, we evaluated the predictability of preoperative CT and magnetic resonance imaging (MRI) for localization of SNIP origin.

OBJECTIVE: To explore the expression and significance of programmed cell death 5 (PDCD5) and Bcelllymphoma/lewkmia-2(Bcl-2) in sinonasal squamous cell carcinoma (SNSCC). METHOD: Immunohistochemical method and Western Blot method was used to determine the expression of PDCD5 and Bcl-2 in specimen of SNSCC in thirty cases, sinonasal inverted papillomas (SNIP) in thirty-eight cases, and normal nasal mucosa in twenty cases. RESULT: (1) The expression of PDCD5 protein in SNSCC significantly decreased compared with SNIP and normal nasal mucosa. (2) The expression of Bcl-2 protein in SNSCC up-regulated obviously compared with SNIP and normal nasal mucosa. (3) Positive rate of PDCD5 protein and Bcl-2 protein in well, moderate and low differentiatied group is respectively 100.00%, 83.33%, 38.89% and 50.00%, 70.83% and 100.00%, the difference was statistically significant (P < 0.05). (4) In the follow-up cases, the survival rate of the patients with higher expression of PDCD5 protein was higher, but that with lower expression of Bcl-2 protein was higher. CONCLUSION The inactivation of PDCD5 protein and the activation of Bcl-2 protein may play an important role in the development of SNSCC, and there are a positive correlation between PDCD5 and Bcl-2 protein in SNSCC, which may be identified as a new therapeutic target.

BACKGROUND AND OBJECTIVES: Maxillary sinus is anatomically located adjacent to the orbit and the skull base, so, in cases of advanced maxillary sinus cancer, it is difficult to completely remove the tumor with sufficient resection margins. Local recurrence is by far the most common cause of treatment failure and the long-term survival rates is low. The purpose of this study is to analyze the treatment outcomes and recurrence patterns of the advanced squamous cell carcinoma of the maxillary sinus after total or radical maxillectomy. SUBJECTS AND METHODS: A group of twenty patients who underwent total or radical maxillectomy for advanced squamous cell carcinoma of the maxillary sinus between 1995 and 2004 were examined. The medical records and radiologic findings of the same 20 patients were retrospectively reviewed. RESULTS: Eleven patients suffered from recurrence during the follow-up period. Isolated local recurrence was most common, and all local recurrences developed within 2 years after the treatment. The most common site of recurrence was the cheek. However, there was no significant difference in the recurrence rate in relation to the degree of tumor differentiation, concurrent inverted papilloma, existence of orbital involvement, the type of maxillectomy, and combined treatment. CONCLUSION: Despite the combined use of surgery and radiotherapy, prognosis of squamous cell carcinoma of the maxillary sinus is very poor as the recurrence rate is 55% within the post-treatment 2 years. Failure at the primary site is the main problem. Chemotherapy was ineffective for the recurred cases, so rescue surgery should be considered for the recurred cases, if resectable

OBJECTIVETo investigate the clinicopathological features and prognosis of patients with the malignant transformation of sinonasal inverted papilloma.

METHODSThirty-two consecutive cases encountered between January 1991 and January 2008 were retrospectively reviewed. Survival rates and prognostic factors were calculated with SPSS 17.0 software using the Kaplan-Meier method and multivariate Cox model survival analysis.

RESULTSThe malignancy accounted for 8.99% of all types of sinonasal inverted papilloma. There were 25 males and 7 females, the median age was 56.5 years. The sites of tumor included 22 cases in nasal cavity and ethmoid sinuses, 10 cases in maxillary sinuses. The tumors included 21 high grade tumors, 8 intermediate grade tumors and 3 low grade tumors. Thirty-two patients were staged as T1(3/32), T2(10/32), T3(16/32), T4(3/32). According to the percentage of the malignant cell in the entire tumor tissue, 5 patients were in grade I, 5 patients were in grade II, 8 patients were in grade III, 14 patients were in grade IV. There were 3 distant metastasis in 32 patients; 19 patients underwent surgery plus postoperative radiotherapy, 10 underwent surgery alone and 3 underwent radiotherapy alone. The 5-year overall survival were 72.5%, and the median overall survival time was 62.2 months. Kaplan-Meier univariate survival analysis indicated that the clinical stages and treatment modalities were prognostic factors, and multivariate Cox model survival analysis confirmed that the clinical stages and treatment modalities were independent factors for overall survival (HR were 4.211 and 0.312, all P < 0.05).

CONCLUSIONSThe morbidity of sinonasal inverted papilloma-associated malignancy is low, the clinical features were not specificity. The clinical stages and treatment modalities may affect the prognosis. Surgery plus postoperative radiotherapy are main treatment means.

Inverted Papilloma arising from mucous membrane of the nasal cavity and paranasal sinuses is rare benign neoplasm, and usually unilateral arise from lateral wall of nasal cavity. This tumor is histologically benign neoplasm but clinically malignant, because of frequent recurrence and extensive bone destruction. And occasionally, this tumor can be transformed to squamous cell carcinoma or verrucous carcinoma. Recently, we have experienced a case of the inverted papilloma with verrucous carcinoma of the nose and paranasal sinuses and patient expired due to extension of intracranial cavity. We report out case with review of current literatures.

Verrucous carcinoma of the penis is a rare invasive carcinoma that originates from squamous epithelial cells. It comprises 5 to 24 percent of all penile malignancies and 5 to 16 percent of all squamous cell carcinoma. In 5 % of cases, it is associated with human papilloma virus (HPV). We describe a case of a 42 year old male, with a I year history of a slowly enlarging verrucous mass which initially presented as a warty papule on the penile shaft.

BACKGROUND AND OBJECTIVES: Various host and tumor parameters, particularly the tumor size and lymph node metastasis have been studied in an attempt to evaluate and decide the optimal treatment of the patients with head and neck carcinomas. Moreover, it has been recognized that prognostic parameters can be useful for the evaluation of biological behaviors of malignancy. The p53 is a tumor suppressor gene and cyclin D1 is a cell cycle regulator, essential for G1 phase progression. Cathepsin D is a lysosomal aspartyl endopeptidase which degrades the extracellular matrix and proteoglycan. But there are still controversy in their clinical meanings in sinonasal malignant tumors. The purpose of this study is to assess the roles of p53, cyclin D1 and cathepsin D in sinonasal tumorigenesis. MATERIALS AND METHOD: 27 inverted papilloma (IPs), 5 IPs associated with malignant transformation, and 16 squamous cell carcinoma tissue specimens were investigated by immunohistochemical staining for p53, cyclin D1, and cathepsin D. Clinicopathologic values were compared with the incidence of p53, cyclin D1, cathepsin D expression in sinonasal malignant tumors. RESULTS: p53/cyclin D1 expressions were increased as tumor progressed and these expressions were statistically significant (p< .05). No significant correlations were found among p53, cyclin D1, cathepsin D and other clinicopathologic factors. CONCLUSION: These data suggest that expressions of p53, cyclin D1 and cathepsin D may play an important role in the tumorigenesis and progression of sinonasal malignant tumor sequence. Also, it is suggested that p53/cyclin D1 expressions may be useful variables for the prognostic assessment of sinonasal malignant tumors. However, it is not enough conclude so based on this result alone. Further studies, such as using molecular biological techniques, will be required to determine that p53/cyclin D1 expressions are related to the development or prognosis of sinonasal malignant tumors.

OBJECTIVE: To investigate the clinical and pathological characteristics of sinonasal neoplasms. METHOD: A cohort of 333 patients with sinonasal neoplasm, which were confirmed by surgical pathology, were enrolled in this study. The clinicopathological characteristics, in terms of age, sex, location, and disease constituent ratio were retrospectively reviewed. RESULT: (1) In this series of patients, there were 200 males and 133 females, aged from 2 to 84 years, with a median of 54 years. The benign to malignant ratio was 1.1:1. As for their origination, 144 tumors arose from the nasal cavity, while, 191 tumors derived from sinus, including 90 from maxillary sinus, 31 from frontal sinus, 46 from ethmoid sinus, and 24 from sphenoidal sinus. (2) Disease constituent ratio decreased in order of epithelial tissue, soft tissue, lymphohematopoietic tissue, bone and cartilaginous tissue, ectopic intracranial tumors. The five most frequent malignant tumors were squamous carcinoma, lymphoma, adenoid cystic carcinoma, malignant melanoma and esthesioneuroblastoma, while, benign tumors ranked in the top five were papilloma, fibroma, osteoma, angioma and ectopic intracranial tumors,respectively. (3) Of 200 cases arising from epithelium, 118 were benign, 82 were malignant, and the benign to malignant ratio was 1.4:1. Of 68 cases from soft tissue, 37 were benign and 31 were malignant tumors (ratio, 1.2:1). Among the 22 cases from bone and cartilaginous tissue, 17 were benign and 5 were malignant (ratio, 3.4:1). With respect to the 29 cases from lymphohematopoietic tissue, the majority of tumors were malignant (28 cases), with only one benign case. In addition, ectopic intracranial tumors were also observed. Besides the above all, 12 cases of other types were found in this work. CONCLUSION Neoplasms from different parts of nasal cavity and paranasal sinus have specific clinical characteristics. The pathological types of these tumors may be highly diverged. The diagnosis and differential diagnosis depend mainly on pathological examination. Comprehensive treatment, which employs surgery in combination with other modalities, is the main strategy for these tumors.
