Approximately 80,000 cases of skin cancer are diagnosed annually in France. The management of these cancers can occur in both university hospital centers and ambulatory surgery centers. Limited data exist regarding the epidemiology of cutaneous cancers treated through ambulatory surgery centers. The objective of our study is to describe the epidemiological characteristics of cutaneous cancers managed in a tertiary ambulatory surgery center.

This is a retrospective, single-center observational study. The included patients were those who underwent surgical excision of one or more skin cancers within the maxillofacial department of a tertiary ambulatory surgery center. Clinical, therapeutic, histopathological, and follow-up data (additional surgery if margins were not clear, progression, recurrence, second cancer…) were collected.

Among the n = 1931 patients operated for a head and neck skin tumor from September 2018 to July 2022, n = 426 (22 %) were diagnosed with cancer upon histological analysis. The median age was 76 years (31–100), with a male-to-female ratio of 1/1. The most frequent locations were the nose (23 %) and cheek (20 %). Ten percent of patients had dual-site skin cancer at initial diagnosis. The most common histological types were basal cell carcinoma (77 %) and squamous cell carcinoma (18 %). Surgical treatment primarily consisted of "excision-reconstruction with local flap" (51 %) or "excision-suture" (34 %). Resection margins were mostly clear (65 %), and only six patients (2 %) experienced local recurrence or progression during follow-up.

Skin cancers are prevalent in ambulatory practice. Surgical treatment allows for effective control of the cancer. Photoprotection, particularly in immunocompromised patients, remains crucial for prevention.
