IntroductionHyperthermic isolated limb perfusion (HILP) has an established role in the management of melanoma, but its role for Merkel cell carcinoma (MCC) is less well defined.MethodsRetrospective review of our institutional experience with HILP for MCC was conducted (2009–2015). Literature search was performed through 04/2015 and 10 studies met inclusion criteria.ResultsFour patients underwent HILP for MCC at our institution. There were no major complications and complete response was achieved in all patients. Early metastatic recurrence developed in two patients. The remaining two had no evidence of disease at last follow‐up (36 months) or death (39 months). Systematic review identified an additional 12 pts that underwent HILP for MCC, for a total of 16 cases. Median age was 73 [IQR 69–78] years and 56% were men. Of the patients with reported follow‐up, 12 (86%) had complete response, 1 had stable disease, and 1 partial response. Four patients developed local–regional recurrence and six distant metastases, all within 6 months. Overall median follow‐up time was 15 [7–36] months.ConclusionAmong a highly selective group of patients, regional perfusion for MCC is safe and has a high complete response rate. HILP is an acceptable therapeutic modality for obtaining durable loco‐regional control but early distant metastatic disease remains a significant cause of mortality. J. Surg.

Diabetic mastopathy is an uncommon, benign disease of the breast that can occur in women with diabetes and clinically mimic breast cancer. We describe a patient with long-standing type 1 diabetes who presented with a palpable breast mass with negative imaging findings on mammography, ultrasonography, and breast MRI. Surgical biopsy and histopathology confirmed diabetic mastopathy. We use this case to highlight the recognition, radiographic features, pathology, and management of this benign breast condition and emphasize that, in diabetic patients, the differential diagnosis of a new breast mass should include diabetic mastopathy.
