Cutaneous adnexal carcinomas (CACs) constitute a rare, heterogenous group of malignant tumours. They make up a small fraction of non-melanoma skin cancers but there are no formal treatment guidelines available, including the recommended surgical excision margins. We performed a retrospective review of the surgical excision margins for CACs to identify the adequacy of primary excisions. Method: Patients who underwent surgical excision of a CAC in the West Australian public system, whose histopathology were reviewed via the Dermatopathology Department of PathWest between August 2018 and August 2024 were included. Patient demographics, operative details, histopathology results and treatment outcomes were collected. Results: A total of 18 patients and 19 lesions were identified. All lesions were histologically consistent with squamoid eccrine ductal carcinoma. The median surgical excision margin was 5 millimetres, with 3 unreported. Eight out of 19 lesions (42%) were incompletely excised. Seven patients underwent re-excision and 8 underwent adjuvant radiotherapy. There were 2 cases of recurrence identified in the follow-up period, with the median follow-up time of 19 months. Currently, there are no practice guidelines for surgical excision margins in the treatment of CACs. Future research should be directed at creating evidence-based guidelines for peripheral and deep surgical margins for these tumours, especially for the more aggressive histological subtypes.
