case_images: At his outpatient clinic follow up visit, the patient reported fevers, night sweats, an erythematous skin lesion distributed over his right chest (Figure 4), and an increase in the size of the right-sided cervical lymph nodes (Figure 5).

case_images: (a) At low magnification, focal effacement of lymph node architecture by cohesive infiltrate of neoplastic cells, extending from the subcapsular sinuses into the paracortical region. (b) At high magnification, large pleomorphic neoplastic cells with abundant eosinophilic cytoplasm, pleomorphic nuclei, and frequent mitotic figures, including a "hallmark" cell with horseshoe-shaped nuclei (blue arrow).

case_images: The pathological analysis yielded focal effacement of the lymph node architecture by large cells with abundant eosinophilic cytoplasm, pleomorphic nuclei, and frequent mitotic figures (Figures 6(a) and 6(b)).
case_images: (a) At high magnification, strong, uniform CD 30 positivity in the cytoplasmic membranes and Golgi regions of the neoplastic cells. (b) At high magnification, diffuse cytoplasmic and nuclear staining for ALK.
