RESUMEN
BACKGROUND/OBJECTIVES: As the New Zealand Cancer Registry does not require mandatory reporting of non-melanoma skin cancers (NMSC), basal cell carcinomas (BCC) and squamous cell carcinomas (SCC), the clinical burden of these diseases is unknown. METHODS: A retrospective review of all patients with histopathology performed allowed us to estimate invasive BCC and SCC in the Auckland region in 2008 (population 1.44 million). RESULTS: During this period, a total of 21 236 NMSC were diagnosed among 13 996 patients, consisting of 5611 SCC lesions (26%) and 15 525 (74%) BCC. The Auckland incidence rates per 100 000 were 425 for SCC and 1177 for BCC. The overall rate of NMSC per 100 000 was 1906.5 (standardised to the census data of Australia 2001); 1385 for BCC and 522 for SCC. Using published data on incidence trends and population growth, we estimate that 29 000-33 000 NMSC would have been excised in Auckland in 2016, and 78 000-87 000 in New Zealand. CONCLUSION: Auckland has the highest reported incidence of invasive NMSC in the world. We believe that high-risk cutaneous SCC and complex BCC should be recorded. Our study provides information for clinicians and health economists on the scale of the problem.

A 23-year-old New Zealand Maori male with tuberous sclerosis (TSC) and associated neurocognitive abnormalities presented with altered behavior and increasing seizure frequency. Endogenous hyperinsulinemia from an underlying insulinoma was confirmed and this was managed surgically. This case represents only the sixth description of insulinoma in TSC to date. The role of the hamartin-tuberin complex in regulation of the mechanistic target of rapamycin pathway provides a plausible pathogenetic mechanism between insulinoma and TSC. This rare disease association should be considered in TSC patients who present with otherwise unexplained worsening neurocognitive symptoms.
