case_images: Two smaller satellite nodules were seen along the mid dorsal forearm, each measuring 2.0 x 2.0 cm (Figure 1).
case_images: H&E staining of the tumor shows a dense perivascular and band-like monomorphous infiltrate composed of markedly atypical, large, pleomorphic epithelioid cells, along with immature cells resembling immunoblasts.

case_images: Over 75% of the atypical lymphoid cells expressed CD30 (Figure 4), but not ALK1 (Figure 5) and EMA (Figure 6), which led to the diagnosis of CD30+ primary cutaneous anaplastic large cell lymphoma (CD30+ PCLCL).
case_images: Histological image of the tumor that shows absence of the ALK-1 protein on the atypical lymphoid cells.
