Abstract Background/Objectives There are limited population‐based data documenting the incidence and management of lentigo maligna ( LM ) invasive melanoma LMM ). We report on occurrence in an Australian population. Methods Prospective collection clinician‐reported situ MIS ; n = 450, capped) localised 3251) notified to New South Wales Cancer Registry over 12‐months 2006–2007. Results The estimated annual all was 27.0 per 100 000 12.2, non‐ 5.9 unclassified 9.0). Patients with or were average approximately 10 years older than those other subtypes P < 0.001). head neck location 59% , 44% <20% majority treated only by specialists. Diagnostic partial biopsies more frequent for subtypes, primary care physicians likely specialists do a punch biopsy shave biopsy. reported median definitive excision margin 5.0 mm compared 7.2 Conclusions In this population, twice as types . Improved strategies diagnosis required.
