- Melanoma In Situ: A Critical Review and Re-Evaluation of Current . . .
Most international clinical guidelines recommend 5–10 mm clinical margins for excision of melanoma in situ (MIS) While the evidence supporting this is weak, these guidelines are generally consistent
- Surgical Management of Melanoma - Cutaneous Melanoma - NCBI Bookshelf
Standards are well established for peripheral margins of excision (Table 1) These guidelines are based on data from randomized controlled trials The excision margins are measured intraoperatively on the skin Current guidelines for melanoma in situ recommend a 5 mm–1 cm peripheral margin
- Wide Local Excision - The American College of Surgeons
The margin width for wide local excision of a melanoma in situ should be 5 mm Standard wide local excision margin recommendations also apply to melanomas of the skin of the digits Subungual melanoma frequently requires amputa-tion of a distal phalanx
- Margins in Skin Excision Biopsies: Principles and Guidelines
In melanoma optimal excision margins (from the edge of the melanoma lesion) suggested are as follows: for In situ melanomas, melanomas of thickness <1 mm, melanomas of thickness 1-4 mm, and >4 mm deep melanomas the margin are supposed to be 5 mm, 1 cm, 2 cm, and 2-5 cm, respectively [15,16] The suggested margin to be taken in squamous and basal

If melanoma is suspected, initial excision biopsy is recommended Wide excision margins are then based on reported tumour thickness Sentinel lymph node biopsy provides important prognostic information and a probable survival benefit for patients with intermediate thickness melanomas
- Recurrence Rate of Melanoma In Situ Excised With a 5-mm Excisional Margin
Today, most clinical guidelines recommend a range of margins of 0 5 to 1 cm for all MIS, noting that the goal of excision is negative histologic margins In this issue of JAMA Dermatology , Sun et al 3 attempt to provide evidence to support the success of a 5-mm margin for a subgroup of patients with MIS that could be appropriately treated in
- Surgical margins for melanoma in situ
Results: In all, 86% of melanoma in situs were successfully excised with a 6-mm margin; 9 mm removed 98 9% of melanoma in situs The superiority of 9-mm to 6-mm margins was significant (P\ 001)
- Surgical margins for melanoma in situ - PubMed
Standard surgical excision of melanoma in situ should include 9 mm of normal-appearing skin, similar to that recommended for early invasive melanoma The frequently recommended 5-mm margin for melanoma is inadequate
