Abstract

Extramedullary haematopoiesis (EMH) is the production of blood cells outside the bone marrow. EMH is frequently seen in organs such as liver and spleen. Intrathoracic EMH can be diagnosed without histopathological confirmation by typical paravertebral radiological location and association with accompanying haematological disease. We report a patient who had atypical presentation of an intrathoracic intraparenchymal nodule. All investigations performed in the patient supported a prediagnosis of malignancy and the diagnosis was only confirmed by lung wedge biopsy. Intrathoracic EMH is a very rare condition. When EMHs are located in the lung parenchyma, they cannot be distinguished by radiological examinations. In this case, they may mimic malignancies and lead the clinician to needle or tissue biopsies with catastrophic results for EMHs. In these patients, complete wedge resection by VATS is a very safe method for diagnosis.

Nadir Bir Olgu: İntratorasik İntraparankimal Ekstramedüller Hematopoez

Abstract

Ekstramedüller hematopoez (EMH), kemik iliği dışında kan hücrelerinin üretilmesidir. EMH sıklıkla karaciğer ve dalak gibi organlarda görülür. İntratorasik EMH, tipik paravertebral radyolojik yerleşim ve eşlik eden hematolojik hastalıkla ilişki ile histopatolojik doğrulama olmadan teşhis edilebilir. Bu olguda atipik bir prezentasyon gösteren intratorasik intraparankimal yerleşime sahip nodülü olan bir hasta sunulacaktır. Hastada yapılan tüm incelemeler malignite açısından şüphe taşımasına rağmen asıl tanı ancak wedge rezeksiyon ile konulabildi. İntratorasik EMH çok nadir görülen bir durumdur. EMH’ler akciğer parankiminde yer aldığında, radyolojik incelemelerle ayırt edilemezler. Bu durumda, maligniteleri taklit edebilirler ve klinisyeni, EMH’ler için katastrofik sonuçlar doğurabilecek olan iğne veya doku biyopsilerine yönlendirebilir. Bu hastalarda VATS ile komplet wedge rezeksiyon tanı için güvenli bir yöntemdir.
