This elderly man was evaluated for a 2 cm dome shaped nodule on the back of the right arm. The histologic findings were consistent with an anaplastic large cell lymphoma with vascular involvement.

Description

There is an atypical mononuclear cell infiltrate that extends into the subcutaneous fat. These cells, which have vesicular nuclei with prominent nucleoli, focally infiltrate the epidermis in a pattern of tagging along the dermal-epidermal junction as well as epidermotropism. Within the infiltrate here is a component of small lymphocyte-like cells. The findings were consistent with an anaplastic large cell lymphoma with vascular involvement.
