A 64-year-old female was admitted to our outpatient clinic with a one-year history of multiple pink nodular lesions of a few millimeters and centimeters in diameter on the chest, back and gluteal regions (Figure 1).

Dermoscopic examination of the nodular lesions revealed pink-to-yellow structureless areas and polymorphous vessels (Figure 2).
Total excision specimen of the nodular lesion on back revealed diffuse dermal cellular infiltration (H&E) (A). The infiltration consisted of large atypical cells with CD3, CD4 and CD30 positivity (B, C) immunohistochemically, as well as negativity for anaplastic lymphoma kinase and CD20 staining (D).

Total excision of the nodular lesion on the back revealed diffuse dermal cellular infiltration histologically (hematoxylin & eosin staining [H&E]). (Figure 3A) The infiltration consisted of large atypical cells with CD3, CD4 and CD30 positivity (Figure 3B and C) on immunohistochemical examination, as well as negativity for anaplastic lymphoma kinase and CD20 staining (Figure 3D).
