The association of polypoid growth pattern with lymphnode involvement in endometrioid type endometrial adenocarcinoma

Background: Tumor size is an independent predictor of lymph node metastasis and survival in the endometrioid type endometrial adenocarcinoma (EC). However, some of the ECs tend to grow towards the cavity in the polypoid pattern, which can reach very large sizes. In this study, we aimed to analyze the association of growing in the polypoid pattern of the tumor with the proportion of lymph node metastasis and extrauterine tumor spread. Methods: Four hundred seven patients were analyzed retrospectively. The effect of tumor size, tumor growing pattern, myometrial invasion, grade, and lymphovascular space invasion on the lymph node metastasis and extrauterine tumor spread were investigated. Statistical analysis consisted of unpaired t?tests for parametric data and Mann Whitney?U test for non?parametric data, whereas the Chi?square test for categorical variables. Logistic Regression, Cox Regression and multivariate analysis were used to estimate the risk predictors. Results: No association was found between the growing in polypoid pattern and lymph node metastasis (P > 0.05). In the analysis of endometrioid type EC patients who had myometrial invasion less than � as a subgroup, no association was found between the growing pattern and lymph node metastasis and extrauterine disease. Tumor size was found to be a statistically significant predictor of lymph node metastasis and extrauterine disease (P < 0.05). Conclusions: Lymphovascular space invasion, grade, and myometrial invasion are associated with a higher proportion of lymph node metastasis. The polypoid growth pattern of the tumor does not correlate with any histopathological parameters

Thick-needle vacuum-assisted biopsy technique for inflammatory breast carcinoma diagnosis

PURPOSE: Inflammatory breast carcinoma (IBC) is a rare clinicopathological cancer type with unique clinical features and a poor prognosis. In this disease, there is generally no palpable mass in the breast. IBC can be mistakenly diagnosed as mastitis and patients may receive a delayed diagnosis and treatment, since these two disorders cause similar pathological appearences on the breast. Clinical suspicion of the disease followed by histopathological observation of occluded dermal lympthatics by tumor emboli leads to definitive diagnosis of IBC. METHODS: Here, we report our experiences in diagnosing IBC using Thick-Needle Aspiration Biopsy (TNAB). RESULTS: Eight patients having clinically suspected IBC, received TNAB. IBC was definitively diagnosed upon observation in histopathological examination of occluded dermal lymphatics by tumor emboli since TNAB allowed adequate tissue sampling. CONCLUSION: In this study, we showed that IBC can be reliably diagnosed using TNAB.

OBJETIVO: O carcinoma inflamatório da mama (CIM) é um raro tipo histopatológico do câncer mamário, com características clínicas especiais e prognóstico reservado. Nesta doença, geralmente não se palpa nódulos mamários. O CIM pode equivocadamente ser diagnosticado como mastite e gerando um retardo no diagnóstico e tratamento, visto que ambas as doenças tem apresentação semelhante. A suspeita clínica da doença seguida da observação histopatológica de embolia tumoral com oclusão dos linfáticos da derme conduz ao diagnóstico definitivo de CIM. MÉTODOS: Relata-se o procedimento no diagnóstico de CIM utilizando a biópsia de aspiração por agulha de grosso calibre (BAAGC). RESULTADOS: Oito pacientes com suspeita clínica CIM foram submetidos a BAAGC. Todos os casos receberam diagnóstico definitivo de CIM após caracterização histopatológica da biópsia. BAAGC permitiu a amostragem adequada do tecido. CONCLUSÃO: O CIM pode ser diagnosticado utilizando BAAGC.
