The recommended method for histopathological diagnosis of cutaneous melanoma is excisional biopsy, although partial biopsies (shave and punch) are often used. Following a partial biopsy, treatment guidelines recommend a narrow excisional biopsy to plan definitive management. There is limited evidence on the benefits of direct wide local excision (WLE) following diagnostic partial biopsies.

Retrospective cohort study of cutaneous melanoma cases, from two tertiary referral centres from January 2013 to December 2015. Demographic and histopathological data, including tumour thickness (T-stage) from initial biopsy and subsequent excisions, were collected. Logistic regression was used to examine histopathological T-staging between biopsy and subsequent excisions (upstaging).

2304 melanomas (2157 patients) were identified; 455 shave, 308 punch, 14 incisional and 1527 excisional biopsies. Out of 1527, 5 (
