Background/Objectives: There is a paucity of Australian data on the use of Mohs micrographic surgery for treating melanoma in situ and lentigo maligna. We share an Australian centre's experience with the technique. Methods: A total of 62 patients with 62 lesions of melanoma in situ and lentigo maligna referred for treatment between 2015 and 2017 comprised the study group. All melanomas were excised with Mohs micrographic surgery utilising melanoma‐associated antigen recognised by T‐cells (MART‐1) immunostaining. Results: Follow up ranged from 3 to 30 months with no reported recurrences or melanoma‐related deaths. 94% (58/62) of lesions were primary melanomas and 6% were locally recurrent. 89% of lesions involved head and neck sites with 11% involving trunk or limbs. In total 55% (12/62) of lesions were cleared with 3‐mm clinical margins, 68% with 6 mm, 92% with 9 mm and 100% with 12‐mm. The mean clinical excision margin was 6.7 mm. All lesions with a tumour diameter greater than 2.2 cm required a 9‐mm clinical margin or greater for excision. The mean clinical excision margin for recurrent tumours was 9 mm. Conclusion: We provide the first Australian data on the use of Mohs micrographic surgery for melanoma. [ABSTRACT FROM AUTHOR]

Medium to large scalp defects with exposed bone can pose particular challenges to the dermatologic surgeon. Most of the publications pertaining to the repair of such defects are presented in the plastic surgery literature. Dermatologic surgeons may have less experience in this area and be hesitant to pursue surgery when these defects may be encountered. The technique described below is a simple, one‐stage reconstruction, with a short healing period, providing adequate cosmesis, and is within the capability of most dermatologic surgeons.
