Objective:To compare the clinical characteristics of nasal NK/T-cell lymphoma（NKTL） and diffuse large B-cell lymphoma（DLBCL） to improve the diagnosis and differential diagnosis of nasal lymphomas. Methods:A retrospective analysis of cases of nasal NKTL and DLBCL was conducted. The clinical symptoms, signs, and imaging features of both groups were compared and statistically analyzed. Results: The DLBCL group showed more symptoms like exophthalmos/diplopia and epiphora compared to the NKTL group （both P=0.040）. NKTL cases were more likely to be misdiagnosed as sinusitis（P=0.007）. In NKTL cases, nasal mucosal swelling（P<0.01）, destruction of nasal structures（P=0.002）, and external nasal structural abnormalities（P=0.003） were more prevalent. In imaging, the DLBCL group more commonly demonstrated worm-eaten destruction of sinus bones （P=0.004）, sinus masses （P=0.018）, and invasion of adjacent structures including the pterygopalatine fossa, infratemporal fossa （P<0.01）, orbit （P=0.039）, and skull base （P=0.011）. NKTL involved the turbinates（P=0.001）, nasal cavity and septum（P=0.016）, nasopharynx（P<0.01）, and "skip" infiltration of external nasal tissues（P=0.042） more frequently. No statistically significant differences were found in other clinical features between the two groups. Conclusion:For patients with nasal obstruction and discharge, it is essential to inquire about systemic B symptoms, such as fever, and eye symptoms, such as periorbital swelling, diplopia, and lacrimation. Lymphoma should be suspected if local examination reveals diffuse nasal swelling, destruction of turbinates or septum, and external nasal structural abnormalities. Worm-eaten bone destruction and "cast-like" changes of the turbinates, septum, and nasal cavity, as well as "skip" infiltration of the external nose, are more common in NKTL. Sinus masses with invasion of the pterygopalatine fossa, infratemporal fossa, skull base, and orbit are more typical of DLBCL.

Objective:To investigate the clinical diagnosis and treatment of IgG4-related disease（IgG4-RD） primarily involving the nasal cavity and skull base. Methods:A retrospective analysis was conducted on the clinical data of 8 patients with IgG4-RD primarily involving the nasal cavity and skull base who visited the Nasal and Skull Base Surgery Department at Xiangya Hospital from October 2017 to January 2024. The cohort comprised 4 males and 4 females, aged 8 to 69 years. Clinical data, laboratory examination results, imaging findings, histopathological results, and treatment plans were collected. The clinical manifestations, diagnosis, treatment and follow-up results of IgG4-RD primarily involving nasal cavity and skull base were summarized and previous literature were also reviewed. Results:The initial symptoms in the 8 patients included nasal congestion, headache, sensory function decline, and facial deformities. Three patients also had parotid and pulmonary involvement. Among the 8 patients, 4 underwent partial surgical resection combined with glucocorticoid therapy; 1 underwent partial surgical resection combined with glucocorticoid and immunosuppressant therapy; 1 received glucocorticoid therapy alone; and 2 received glucocorticoid combined with immunosuppressant therapy. Follow-up was conducted one month after treatment, lasting from 5 to 79 months. During the follow-up period, recurrence was observed in 1 patient treated with glucocorticoid combined with immunosuppressants and in 1 patient treated with glucocorticoid alone, while the other 6 patients achieved significant remission. Conclusion:The diagnosis of nasal cavity and skull base IgG4-RD requires the combination of histopathology, laboratory tests, and imaging results. Treatment primarily includes glucocorticoids or combined immunosuppressants. For patients with significant compression symptoms, sensory function impairment, or facial deformities, surgical resection is an important treatment option. Given the high risk of recurrence, early intervention, active treatment, and long-term follow-up are crucial.

Objective: To summarize the preliminary experience in the treatment of esthesioneuroblastoma (ENB) and to explore the effect of age, chemotherapy, modified Kadish stage and pathological grade on the prognosis of ENB. Methods: The clinical data of 87 ENB patients from the First Affiliated Hospital of Sun Yat-sen University and Sun Yat-sen University Cancer Center between June 2002 and November 2017 were retrospectively analyzed. The modified Kadish stage was used to evaluate the extent of the lesions, and the Hyams grading system was used for pathological grading. The patients were followed up regularly to evaluate the recurrence and metastasis of the tumor. Cox proportional hazard model was used for univariate and multivariate analyses. Prognostic factors with P<0.05 in univariate analysis were included in multivariate analysis. After controlling the confounding factors, the model coefficients were used to calculate the hazard ratio (HR) and 95% confidence interval (CI). Results: The median follow-up time of ENB patients was 29 months, and the 5-year overall survival rate was 39.3%. In univariate analysis, age, chemotherapy, modified Kadish stage and pathology grade were independent predictors of overall survival, while gender, radiotherapy and surgery were not prognostic factors. Multivariate analysis showed that modified Kadish stage and pathology grade were independent predictors of overall survival rate after excluding confounding factors. Conclusions: Age, chemotherapy, modified Kadish stage and pathological grade are taking important role in the overall survival rate of patients with ENB. Modified Kadish stage and pathological grade are independent predictors of overall survival rate.

Nuclear protein of the testis midline carcinoma (NMC) is a rare malignant tumor that is mostly located in the upper trachea,mediastinal midline,and paravertebral midline,and few literature has described the imaging features of NMC in the nasal cavity and paranasal sinuses. In this article we summarize the clinical,radiologic,and pathologic data of one case of pathologically confirmed NMC in the nasal cavity and paranasal sinus by focusing on its CT and magnetic resonance imaging features.

nasal cavity. Here, we report the case of an EMC arising from the inferior turbinate, one of the most uncommon sites. A 60-year-old female patient presented with left nasal obstruction for several months, and PNS CT showed an about 4×1.4-cm-sized heterogeneously enhancing polypoid mass originating from the inferior turbinate of the left nasal cavity. After surgical treatment, the patient was diagnosed with EMC based on pathologic examinations including histopathological and immunohistochemical tests. We report a case of a patient with EMC in the inferior turbinate who was observed over 18 months without radiation therapy after successful wide excision.]]>

OBJECTIVES: To investigate the clinical and pathological features of patients with unilateral sinonasal disease (USD). METHODS: A retrospective analysis was completed on 376 adult patients with USD from January 2015 to December 2016. Their presenting symptoms, nasal endoscope, CT scanning, and pathology were analyzed respectively. RESULTS: Among the 267 (71.01%) patients with inflammatory disease, there were 4 pathological types. And there were 8 pathological types in 60 (15.96%) patients with benign tumor. Of the 49 patients with malignant tumor, there were 15 pathological types which included squamous carcinoma, malignant melanoma, and lymphoma, as well as myoepithelial carcinoma and Mesodermal mesoderm. The onset age of inflammation group was younger than that of benign (<0.05) or malignant tumor groups (<0.05). The misdiagnosis rate was 8.33% in benign tumor (5/60), and 10.20% in malignant tumor (5/49). Nasal polyps was the most common misdiagnosis in the groups of benign and malignant tumor. CONCLUSIONS The pathology of adult patients with USD is complicated, and no specific clinical feature was found for distinguishing between benign and malignant lesions. The tumor took a quite proportion in adult patients with USD. Therefore, careful consideration should be taken before diagnosing patients with USD in order to reduce misdiagnosis rate.

A patient with a history of adenoid cystic carcinoma of the nasal cavity presented himself with bone pain and an elevated PSA level. On suspicion of metastatic prostate cancer a ⁶⁸Ga-PSMA PET-CT was performed. The PET-CT showed numerous lung and non-sclerotic bone metastasis. Biopsy of a bone metastasis was performed and pathology showed adenoid cystic carcinoma instead of prostate cancer. Immunohistochemical PSMA staining of the primary tumour showed intense PSMA expression in adenoid cystic carcinoma tumour cells. Because of the high PSMA expression of adenoid cystic carcinoma, ⁶⁸Ga-PSMA PET-CT might be a promising imaging modality for this malignancy.
