Figure 4: (a) Contrast-enhanced computed tomography chest – heterogeneously enhancing mass lesion in the right upper lobe of lung (RUL). (b) Bronchial brush Leishman–Giemsa stain (×40) – Abortive glands of malignant cells suggestive of adenocarcinoma. (c) Contrast-enhanced computed tomography chest – Heterogeneously enhancing mass lesion in anterior segment of left upper lobe of lung (LUL) with necrosis. (d) Bronchial brush Leishman–Giemsa stain (×40) – Polygonal malignant squamous cells in single cluster with intercellular bridges suggestive of squamous cell carcinoma. (e) Transbronchial needle aspiration Leishman–Giemsa stain (×10) – Clusters of malignant spindle cells suggestive of spindle cell tumor. (f) Bronchoalveolar lavage fluid Leishman–Giemsa stain (×20) – Monotonous sheets of malignant lymphocytes suggestive of lymphoma
