Figure 1: (a-c) Clinical pictures. (a) A reddish, ulcerated tumor (6 cm in diameter) and a red-brown papule adjacent to the tumor on the right buttock. (b and c) Multiple papules and postinflammatory pigmentation on (b) the left upper abdomen and (c) the thighs. (d) Hematoxylin–eosin staining of the tumor on the buttock. Massive infiltration of large atypical and pleomorphic cells with abundant mitoses was observed throughout the entire dermis. (e-h) Immunohistochemical staining for (e) CD30, (f) CD8, (g) anaplastic lymphoma kinase, and (h) Ki-67 of the large cells. (i) An ulcerated tumor on the left axilla. (Original magnification: [d-h] ×200).
