Abstract

Pseudoangiomatous stromal hyperplasia is a benign proliferative lesion of the mammary stroma that rarely presents as a localized mass. Pseudoangiomatous stromal hyperplasia is characterized by a dense, collagenous proliferation of the mammary stroma, associated with capillary-like spaces. Pseudoangiomatous stromal hyperplasia can be mistaken with fibroadenoma on radiological examination or with low-grade angiosarcoma on histological examination. Its main importance is its distinction from angiosarcoma. The presented case was a 40-year-old woman who was admitted with a rapidly growing breast tumor. Physical examination revealed an elastic-firm, well-defined, mobile and painless mass in her right breast. Mammograms revealed a 6.7x3.7 cm, lobulated, well-circumscribed mass in her right breast but no calcification. Sonographic examination showed a well-defined and homogenous mass, not including any cyst. Based on these findings, a provisional diagnosis of fibroadenoma was made. Considering the rapid growth history of the mass, tumor excision was performed. The excised tumor was well demarcated and had a smooth external surface. Histological examination revealed the tumor to be composed of markedly increased fibrous stroma and scattered epithelial components (cystic dilatation of the ducts, blunt duct adenosis). The fibrous stroma contained numerous anastomosing slit-like spaces. Isolated spindle cells appeared intermittently at the margins of the spaces resembled endothelial cells. Immunohistochemical staining showed that the spindle cells were positive for CD34 and negative for Factor VIII-related antigen. The lesion was diagnosed as nodular pseudoangiomatous stromal hyperplasia.

Özet

Psödoanjiyomatöz stromal hiperplazi, meme stromasının benign proliferatif bir lezyonu olup nadiren lokalize bir kitle şeklinde görülür. Psödoanjiyomatöz stromal hiperplazi, kapiller benzeri boşluklar içeren meme stromasının yoğun, kollajenöz proliferasyonu ile karakterizedir. Radyolojik incelemede fibroadenom ya da histolojik incelemede düşük dereceli anjiyosarkom olarak yanlış tanı alabilir. Bu lezyonun asıl önemi, anjiyosarkomdan ayırt edilmesidir. Sunulan olgu hızla büyüyen meme tümörü nedeniyle başvuran 40 yaşında kadın hastadır. Fizik muayenede sağ memede elastik-sert kıvamda, iyi sınırlı, hareketli ve ağrısız bir kitle saptandı. Mammografide, sağ memede 6,7x3,7 cm boyutlarında, lobule, iyi sınırlı kitle izlendi, kalsifikasyon görülmedi. Ultrasonografi'de 7,4x6x3,2 cm boyutlarında iyi sınırlı ve kist içermeyen homojenöz kitle izlendi. Bu bulgulara dayanarak, fibroadenom ön tanısı konmuş ve kitlenin hızlı büyüme öyküsü nedeniyle tümör eksizyonu yapılmıştır. Eksize edilen tümör iyi sınırlıydı ve düzgün dış yüzeye sahipti. Histolojik inceleme tümörün belirgin artmış fibröz stroma ve saçılmış epitelial komponentlerden (duktusların kistik dilatasyonu, kör duktus adenozis) oluştuğunu gösterdi. Fibröz stroma çok sayıda anastomoz yapan yarık-benzeri boşluklar içermekteydi. Boşlukların sınırlarını aralıklı olarak döşeyen izole iğsi hücreler, endotel hücrelerine benzer görünümdeydi. İmmünohistokimyasal boyama, iğsi hücrelerin CD34 pozitif ve Faktör-VIII negatif olduğunu gösterdi. Lezyon, nodüler psödoanjiyomatöz stromal hiperplazi olarak değerlendirildi.
