This follow-up study of LM surgical treatments shows excellent outcomes for wide excision and MMS. Because this is a nonrandomized retrospective study, no direct comparisons between the 2 treatments can be made. When recurrences occurred, repeat surgery, either standard excision or MMS, was usually sufficient to provide definitive cure.

Mucous membrane pemphigoid and pemphigus vulgaris are autoimmune blistering disorders in which many similar drugs and therapeutic strategies are utilized. In general, localized disease can be treated with topical agents. In contrast, patients with more severe and progressive disease usually require a combination of systemic corticosteroids and immunosuppressive medications. Oral corticosteroids, adjuvant immunosuppressive agents, antibiotics such as dapsone and immunomodulatory procedures like intravenous immunoglobulin are the main therapeutic agents used in treating these two disorders. Much of the morbidity and mortality associated with these disorders are related to the sites involved and to the drugs used for therapy. Treatment should be individualized based on severity, extent, and rate of progression of disease, comorbidities, and age of the patient. Serum levels of specific autoantibodies and indirect immunofluorescence titers, in certain cases, can be used to monitor response to therapy.

Background The incidence of lentigo maligna (LM) may be increasing, but no population-based epidemiologic studies have been performed. Objective To determine the incidence of LM in Olmsted County, Minnesota, as well as overall and recurrence-free survival. Methods Using the Rochester Epidemiology Project, we identified all adult residents of Olmsted County, Minnesota, with a first lifetime diagnosis of LM between 1970 and 2007. Medical records were reviewed to determine demographic, clinical, and surgical data, and incidence and survival were calculated. Results Among 145 patients identified, median (range) age at diagnosis of LM was 70 (33-97) years. Treatment changed over time, with Mohs micrographic surgery becoming available after 1986. No patients died of LM; 5 had local recurrence. Estimated local recurrence-free survival at 5, 10, 15, and 20 years after diagnosis was 98%, 96%, 92%, and 92%, respectively. Overall age- and sex-adjusted incidence of LM among adults was 6.3 per 100,000 person-years, increasing from 2.2 between 1970 and 1989 to 13.7 between 2004 and 2007. Limitations Retrospective study; homogeneous population. Conclusion The incidence of LM increased significantly among residents of Olmsted County, Minnesota, over an extended time frame, with incidence being significantly higher among men than women and increasing with age.
