Metastatic Invasive Lobular Breast Carcinoma Mimicking Synchronous Breast and Gastric Cancers

Abstract

Metastatic lobular carcinoma to stomach is seen as small round cells in linear cords within the normal tissue and it is not easily differentiated from signet cell adenocarcinoma of the stomach. Differentiating synchronous primary gastric carcinoma from metastatic involvement is vital in accurately planning treatment. Herein, we report a case of gastric metastatic invasive lobular breast carcinoma initially misdiagnosed as synchronous gastric and breast carcinoma and discuss the diagnostic and therapeutic challenges.

Senkron Meme ve Mide Kanserlerini Taklit Eden Metastatik İnvazif Lobüler Meme Karsinomu

Abstract

Memenin lobüler karsinomunun mide metastazı küçük yuvarlak hücreler olarak gözlenir, lineer kordonlar yapar ve midenin taşlı yüzük hücreli kanserinden ayrımı zordur. Bu ayırıcı tanı hastanın tedavisini uygun şekilde planlamada hayati öneme sahiptir. Bu vakada başlangıçta senkron gastrik ve meme karsinomu tanısı konulan, sonrasında metastatik invazif lobüler karsinom tanısı alan olgunun seyri ve bu konuda tanı ve tedavi yaklaşımlarının literatür tartışması sunulmuştur.
