Biennial Meeting Program

February Case of the Month Clinical History: An 84-year-old woman with a history of smoking was found to have a 7.6 cm mass in the right lower lobe with satelite lesions and FDG-avid thoracic lymphadenopathy. Endobronchial ultrasound sampling of the 4R lymph node showed an abnormal population of small to intermediate-sized cells arranged in solid nests and rosettes with prominent crush artifact (Figure 1). The cells show high nuclear to cytoplasmic ratios, nuclear molding, scant cytoplasm, and fine chromatin with occasional indistinct nucleoli (Figure 2). Mitotic forms and apoptotic forms are easily identified. Work-up demonstrates diffuse keratin AE1/AE3 expression (Figure 3), whilst antibodies directed against synaptophysin, chromogranin, INSM1, p40, desmin, MyoD1, and TTF-1 (Figure 4) are non-reactive. There is focal membranous staining for CD56 (Figure 5). POU2F3 is positive (Figure 6). Ki-67 is over 90%.
