Importance Staged excision of lentigo maligna (LM) often requires multiple stages and can result in significant cosmetic morbidity. Imiquimod cream has been used off-label as monotherapy in the treatment of LM and may be used in the neoadjuvant setting prior to staged excision as a strategy to reduce the size of the surgical margins required to confirm negative histologic margins. Objective To examine the rate of recurrence of LM in patients treated with neoadjuvant topical imiquimod, 5%, cream prior to conservatively staged excisions. Design, Setting, and Participants This was a retrospective medical record review of 334 patients with 345 biopsy-confirmed LM tumors from June 2004 to January 2012 who were treated with imiquimod prior to undergoing staged excisions at the University of Utah Medical Center and Huntsman Cancer Institute, large academic hospitals in Salt Lake City. Interventions Patients were treated with off-label imiquimod, 5%, cream 5 nights per week for 2 to 3 months. Those deemed to have an inadequate inflammatory response were also treated with tazarotene, 0.1%, gel twice weekly. Conservatively staged excisions, beginning with 2-mm margins, were then performed. Main Outcomes and Measures The rate of recurrence of LM after long-term follow-up. Results Patients included 235 men (70%) and 99 women (30%) with a mean (SD) age of 67 (13) years. Patients were treated with imiquimod cream for a mean of 2.5 months prior to undergoing conservatively staged excisions. There were 12 local recurrences (a rate of 3.9%) with a mean time to recurrence of 4.3 years and a mean length of follow-up of 5.5 years. Conclusions and Relevance Neoadjuvant topical imiquimod, 5%, cream prior to conservatively staged excisions for LM allowed for negative histologic margins with a median final margin of 2 mm and a rate of recurrence similar to reported recurrence rates with standard staged excisions by either Mohs surgery or en face permanent sections.

BACKGROUND Nonmelanoma skin cancer (NMSC) of the ear can result in large defects with significant morbidity. OBJECTIVE To determine whether subanatomic location of NMSCs, based on ease of visualization of the ear, correlated with post-Mohs micrographic surgery (MMS) defect size. METHODS A retrospective chart review of 142 post-MMS ear lesions was performed and categorized according to subanatomic location: the helix, antihelix, and tragus (Location 1); retroauricular (Location 2); and conchal bowl, scapha, and triangular fossa (Location 3). RESULTS The average defect sizes were 2.50 cm2 (Location 1), 5.76 cm2 (Location 2), and 4.03 cm2 (Location 3). Tumors in Location 1 were significantly smaller than those occurring in Location 2 (P

Objective To better understand postoperative opioid use after dermatologic surgery. Design Prospective observational study. Setting Academic dermatology department. Patients The study included 212 adults (1) who were undergoing a single skin excision (including Mohs micrographic surgery), (2) who consented to participate, and (3) who were able to be reached by telephone on postoperative day 3 or 4. Patients who did not meet these criteria and those referred to another physician for further surgical treatment or repair were excluded. Main Outcome Measures The study examined (1) the incidence of opioid prescription after dermatologic surgery, (2) the percentage of prescribed opioid pain medications used in the postoperative period, and (3) patient and surgical characteristics associated with opioid pain medication prescription and use. Results Opioids were prescribed to 72 of the 212 patients (34%). Twenty-five of the 72 patients (35%) who were prescribed opioids did not use them. Forty-nine of 57 patients (86%) who filled an opioid prescription had leftover pills, and 26 of the 49 patients (53%) planned to keep them. Only maximum pain score was significantly associated with opioid use. Conclusions Opioids were overprescribed after dermatologic surgery. Patients who had leftover opioids did not dispose of them properly, which could lead to potential misuse and abuse.

Objective To determine if the complete response rates of lentigo maligna (LM) to imiquimod, 5%, cream can be improved by the addition of a topical retinoid. Design Prospective randomized study of patients treated with imiquimod alone vs imiquimod plus a topical retinoid, followed by conservative staged excisions. Setting Mohs surgical clinic in an academic institution. Patients Ninety patients with biopsy-confirmed LM. Interventions Ninety patients with 91 LMs were randomized into 2 groups. One group received imiquimod, 5%, cream 5 d/wk for 3 months, while the other group also received tazarotene, 0.1%, gel 2 d/wk for 3 months. Following topical therapy, all patients underwent staged excisions and frozen section analysis with Melan-A immunostaining to confirm negative margins. Main Outcome Measure The presence or absence of residual LM at the time of staged excision. Results Forty-six patients with 47 LMs were randomized to receive monotherapy: 42 of 47 LMs reached the intended treatment duration, with 27 complete responses (64%). Forty-four patients with 44 LMs were randomized to receive combined therapy: 37 of 44 LMs reached the intended treatment duration, with 29 complete responses (78%). This difference did not reach statistical significance (P = .17). There have been no recurrences to date, with a mean follow-up period of 42 months. Conclusions Among patients who received topical imiquimod with vs without tazarotene, 22% (8 of 37) of lesions vs 36% (15 of 42) of lesions showed residual LM on staged excisions. Pretreating LM with imiquimod, 5%, cream may decrease surgical defect sizes; however, total reliance on topical imiquimod as an alternative to surgery may put the patient at increased risk of a local recurrence.
