Abstract

Memenin filloides tümörleri nadir tümörler olup malign formu çok daha nadirdir. Malign formları da dahil tüm filloides tümörlerde intratümöral karsinom gelişimi olabilir. Ancak kollizyon tümörünün bir parçası olarak malign filloides tümör ve eşlik eden invaziv duktal karsinom ise çok nadir bir klinik antitedir. Malign filloides tümörün spesifik radyolojik bulgusu olmadığı için tanı histopatolojik değerlendirme ile yapılır. Eşlik eden tümörün saptanması da çok dikkatli makroskobik ve mikroskobik değerlendirmeler ile mümkündür. Biz bu sunumda 44 yaşında kadın hastada aynı memede heterolog komponentli malign filloides tümör ve arada geçiş zonu bulunmayan invaziv duktal karsinom olgusunu bildiriyoruz. Preoperatif dönemde radyolojik olarak veya cerrahi sırasında saptanmamış kollizyon tümörünün tanısında tümörden kapsamlı patolojik örneklemeler ile çok dikkatli makroskobik değerlendirme önemlidir. Malign filloides tümör hematojen yayılım gösterir, bu nedenle de aksiller lenf nodu diseksiyonuna gerek yoktur. Ancak karsinom ile birliktelik durumunda, tedavi şeklini ve prognozu karsinom evresi belirler.

Collision Tumor in the Breast: Malignant Phyllodes Tumor with Heterologous Component and Invasive Breast Carcinoma, No Special Type

Abstract

Phyllodes tumors of the breast are rare tumors, and the malignant form is much rarer. Intratumoral carcinoma may develop in all phyllodes tumors, including their malignant forms. However, malignant phyllodes tumor as a part of collision tumor and accompanying invasive ductal carcinoma is a very rare clinical entity. Since malignant phyllodes tumor does not have specific radiological findings, the diagnosis is made by histopathological evaluation. Detection of the accompanying tumor is also possible with very careful macroscopic and microscopic evaluations. In this report, we report a case of malignant phyllodes tumor with heterologous component and invasive ductal carcinoma with no transition zone in the same breast of a 44-year-old female patient. Intense sampling and very careful macroscopic evaluation are important in the diagnosis of a collision tumor that was not detected radiologically or during surgery in the preoperative period. Malignant phyllodes tumor spreads hematogenously, so axillary lymph node dissection is not required. However, in the case of association with carcinoma, the type of treatment and prognosis are determined by the carcinoma stage.
