Abstract
Ekstramedüller hematopoez, hematopoetik dokunun kemik iliği ve periferik kan dışındaki neoplastik olmayan proliferasyonudur. Ekstramedüller hematopoeze pek çok organ ve tümör içerisinde rastlanılabilmektedir. Dismenore ve metroraji şikayetleri ile hastanemize başvuran 37 yaşındaki hastaya radyolojik görüntülemelerde izlenen submukozal myom nedeniyle myomektomi uygulanmıştır. Materyalin mikroskobik incelemesinde, tümör hücrelerinin birbirini çaprazlayan demetler şeklinde düzenlenmiş iğsi hücrelerden oluştuğu görülmüştür. Morfolojik olarak leiomyoma benzeyen bu tümör, büyük büyütmede incelendiğinde, stromasında küçük odaklar halinde yerleşim gösteren, hiperkromatik nükleuslu, nükleus /sitoplazma oranları yüksek, değişik büyüklüklerde birkaç farklı hücre grubundan oluşan hücre topluluklarına rastlanmıştır. Uygulanan immünohistokimyasal çalışmalar sonucunda odaklardaki hücrelerden bazılarının glikoforin A, bazılarının ise myeloperoksidaz ile immünreaktivite gösterdiği görülmüştür. Morfolojik ve immünohistokimyasal boyamalar sonucunda bu hücre gruplarının eritroid ve myeloid seri öncülleri içeren ekstramedüller hematopoez alanları olduğu ortaya konmuş, olgu ekstramedüller hematopoez alanları içeren leiomyoma olarak raporlanmıştır. Leiomyoma, üreme çağındaki kadınlarda sık rastlanılan benign düz kas tümörü olmakla birlikte, literatür incelendiğinde, ekstramedüller hematopoez alanları içeren leiomyom olgusunun az sayıda olduğu görülmüştür.
Extramedullary hematopoiesis is non-neoplastic proliferation of hematopoietic tissue other than bone marrow and peripheral blood. Extramedullary hematopoiesis can be found in many organs and tumors. Myomectomy was applied to the 37-year-old patient who was admitted to our hospital with the complaints of dysmenorrhea and metrorrhagia due to submucosal myoma observed in radiological imaging. In the microscopic examination of the material, it was seen that tumor cells consist of spindle cells arranged as bundles that cross each other. When this tumor, which is morphologically similar to leiomyoma, was examined at high power, cell groups consisting of several different cell types of different sizes, with hyperchromatic nucleus, high nucleus/cytoplasm ratios, sawed in the stroma of leiomyoma. As a result of immunohistochemical studies, some of the cells in the foci showed immunoreactivity with glycophorin A and some with myeloperoxidase. Morphological and immunohistochemical staining revealed that these cell groups were extramedullary hematopoiesis containing erythroid and myeloid serial precursors and the case was reported as leiomyoma containing extramedullary hematopoiesis. Although leiomyoma is a benign smooth muscle tumor that is common in women of reproductive age, it has been observed that the case of leiomyoma involving extramedullary hematopoiesis areas is rare.
