OBJECTIVE. The objective of this article is to illustrate the spectrum of imaging findings with photographic and histopathologic correlation in patients with biopsy-proven nephrogenic systemic fibrosis (NSF).

CONCLUSION. Features of NSF may be evident on the patient's skin as well as on routine imaging studies, although these imaging findings are nonspecific and are more likely to occur with other diseases.

Pralatrexate is a novel antifolate, which shows increased antitumor activity in human tumor xenograft studies in mice compared with methotrexate. We investigated the effects of pralatrexate in a patient with adult T-cell lymphoma/leukemia with significant skin involvement. Atypical lymphocytes in epidermal Pautrier microabscesses were positive for HTLV-1. After the patient presented with leukemic conversion and with worsening of an erythematous generalized papular rash, he received one dose of pralatrexate. Within one week, his skin developed innumerable small erosions limited to the areas of the papular rash, sparing unaffected skin. Here we present in vivo evidence that pralatrexate-induced erosions in skin affected by adult T-cell lymphoma/leukemia are a manifestation of apoptosis of tumor cells infiltrating the epidermis and are not the result of cytotoxicity by pralatrexate on keratinocytes. This distinction is critical and may profoundly influence the clinical decision to continue pralatrexate treatment. Pralatrexate-induced skin erosions may indicate response to treatment.
