case_images: Bone marrow aspiration was indicated, with an increased ratio of erythroid series and increased megakaryocytes, and a biopsy of the bone marrow from the iliac bone had a normal appearance on pathologic examination (Fig 1).
case_images: Chest computed tomography reveals (a) a 3.0 x 2.6 cm2 soft tissue density shadow in the lower lobe parenchyma of the left lung field, and (b) the lower lobe of the left lung resection.

case_images: A chest computed tomography (CT) scan on admission showed a 3.0 x 2.6 cm2 mass in the lower lobe of the left lung, with no mediastinal or intrapulmonary lymphadenopathy (Fig 2a). The patient was followed-up every three months for 10 months after the surgery, and chest CT (Fig 2b), cranial magnetic resonance imaging, and skeleton emission CT indicated no relapse or metastasis.
