RESUMO

OBJECTIVE: To investigate the clinicopathologic features of reactive hyperplasia of lymph nodes in maxillofacial regions. METHODS: Thirty-two patients with lymph node reactive hyperplasia (LRH) were analyzed clinicopathologically including pathomorphologic manifestation and immunohistochemical expression. RESULTS: Histopathology of 32 patients showed significant hyperplasia in folliculus lymphaticus, marginal zone lymph, paracortical area lymph, and seldom mixed hyperplasia. Immunohistochemical study showed that the hyperplastic lymphocytes were mainly composed of CD20 positive B cells positive in 23 cases(72%), CD3 positive T cell in 7 cases (22%), CD20 positive T cell and CD3 positive B cell partially as well as histiocytes in 2 cases (6%). Atypical hyperplasia was found in 10 cases. CONCLUSION: Hyperplastic lymphocytes in LRH of maxillofacial regions are mainly composed of B cells. Malignant transformation may occur in these patients with atypical hyperplasia. Regularity follow up is necessary for these patients.

RESUMO

Calcifying epithelioma is one kind of benign tumour,which rarely happens in the neck. The clinical diagnosis of calcifying epithelioma is difficult and misdiagnosis is common. This paper reported one case of calcifying epithelioma in the neck, and discussed its clinical features and therapy based on literature review.

RESUMO

OBJECTIVE: To investigate the relationship between extracapsular spread (ECS) of cervical metastatic lymph node and the recurrence in patients with oral squamous cell carcinoma (OSCC). METHODS: The medical records of 74 OSCC patients with histologically confirmed cervical lymph node metastasis were reviewed. They were divided into 2 groups, ECS positive (ECS+) and ECS negative (ECS-). The treatment results were followed up. Statistical analysis, with chi-square test, and multiple logistic regression was conducted. RESULTS: The overall recurrence rates for pN+/ECS- and pN+/ECS+ patients were 47.6% and 75.0%, respectively, and the cervical recurrence rates for pN+/ECS- and pN+/ECS+ patients were 9.5% and 46.9%, respectively (P < 0.001). Multivariate analysis showed that ECS was one of the independent prognosis factors for cervical recurrence. CONCLUSIONS: Extracapsular spread significantly increased both overall and cervical recurrence rates, and ESC may be a prognosis factor for OSCC patients.
