Abstract

Matrix-producing carcinoma (MPC) is an uncommon variant of metaplastic carcinoma. It was first described by Wargotz and Norris in 1989 as invasive breast carcinoma with direct transition to cartilaginous stroma without intervening spindle cell component. Since then, several studies, mostly in the form of case reports or case series, have been reported and the origin of tumor cell, importance of appropriate terminology for the tumor, histopathological differential diagnosis, benign breast lesions that the tumor could correlate with, and prognosis and consequently the treatment modalities have been discussed. A 43-year-old woman referred to our clinic with a lump in her left breast. Physical examination and radiological findings were consistent with malignancy. Core biopsy of the lesion was reported as “invasive breast carcinoma” and then breast-conserving surgery with sentinel lymph node dissection was performed. The case was diagnosed as MPC of the breast. The literature findings imply epithelial cell (ductal and/or myoepithelial) nature of this tumor. The prognosis is still controversial. Histopathological evaluation of sufficiently sampled surgical excision material is important to recognize and make a correct diagnosis.

Özet

Matriks üreten karsinom, metaplastik karsinomun nadir görülen alt tiplerinden biridir. İlk kez 1989 yılında Wargotz ve Norris tarafından tanımlandığında, arada iğsi hücreli komponent bulundurmadan kıkırdaksı stromaya direkt geçiş gösteren invaziv meme karsinomu şeklinde tarif edilmiştir. O günden bu yana, tümörün kaynaklandığı hücre tipi, doğru terminolojiyle ifade edilmesinin önemi, histopatolojik ayırıcı tanısı, ilişkili olduğu benign meme lezyonları, prognozu ve tedavi yöntemleri genelde vaka sunumu ve vaka serileri şeklindeki yayınlar ile tartışılmıştır. 43 yaşında kadın hasta kliniğe sol memede kitle şikayetiyle başvurdu. Fizik muayene ve radyolojik bulguları malignite ile uyumluydu. Tru-cut biyopsisi “invaziv meme karsinomu” olarak rapor edildi. Meme koruyucu cerrahi ve sentinel lenf nodu diseksiyonu sonucu vaka “memenin matriks üreten karsinomu” tanısı aldı. Literatürde matriks üreten karsinomun kaynaklandığı hücrenin epitelyal (duktal ve/veya myoepitelyal) karakterde olduğu ifade edilmektedir. Prognozu ise hala tartışma konusudur. Bu tümörün tanınması ve ayırıcı tanısının doğru olarak yapılması için yeterince örneklenmiş cerrahi eksizyon materyalinin histopatolojik olarak değerlendirilmesi gereklidir.
