Abstract

Pleomorphic carcinoma, characterized by aggressive behaviour, is a rare variant of invasive lobular carcinoma. Generally the oestrogen, progesterone, and Her2/neu receptors stain positively. Our case is a 43 year-old female patient who has bloody discharge and pain complaints on her right mammary for 5 months. On microscopic examination, a tumoral formation, consisting of cells with abundant eosinophilic cytoplasms, large hyperchromatic nuclei, some with prominent nucleoli, featuring many atypical mitoses is observed containing lobular carcinoma in situ areas inside the tumor. Immunohistochemically, it was determined that the tumor did not express oestrogen, progesterone, and Her2/neu receptors, and the Ki-67 proliferation index was about 30%. For the reason that there are few cases not expressing oestrogen, progesterone, and Her2/neu receptors, our case is considered worthy for presentation.

Özet

Pleomorfik karsinom, invaziv lobüler karsinomun nadir görülen ve agresif seyreden bir varyantıdır. Genelde östrojen, progesteron ve Her2/neu reseptörleri pozitif boyanır. Vakamız 5 aydır sağ memede kanlı akıntı ve ağrı şikayeti olan 43 yaşında kadın hastadır. Mikroskopik incelemede geniş eozinofilik sitoplazmalı, iri hiperkromatik çekirdekli, bazılarının nükleolusları belirgin, çok sayıda atipik mitoz içeren, çevresinde yaygın lobüler karsinoma insitu odakları bulunan tümöral oluşum izlendi. İmmünohistokimyasal olarak tümörün östrogen, progesteron, Her2/neu eksprese etmediği, Ki-67 proliferasyon indeksinin %30 civarında olduğu saptandı. Literatürde az sayıda olgunun bizim vakamızda olduğu gibi östrojen, progesteron ve Her2/neu reseptörlerini eksprese etmediği gösterilmiş ve vakamız bu yönüyle dikkate değer bulunmuştur.
