Multiple inflammatory lesions in an oncology patient

Figure 1 Multiple erythematous papules. Notice that the inflammation is well limited. The most affected areas were the chest, upper back, forearms, and lower legs. It is important to note that the face and scalp (not shown) were completely spared Figure 2 A punch biopsy specimen from the trunk shows an atrophic epidermis with keratinocytes atypia, dyskeratosis, and a dense lymphocytic inflammatory infiltrate (hematoxylin–eosin stain, original magnification 940) Figure 3 At higher magnification, the lichenoid infiltrate and epidermal changes may be observed. Epidermal dysmaturation consistent in disruption of keratinocyte maturation, apoptotic cells, and irregular nucleus is present (hematoxylin–eosin stain, original magnification 9100)
