Malignant melanoma (MM) on the trunk, because of its anatomical location, has multiple potential lymphatic basins to which to drain. The aim of this study is to map the location of the sentinel lymph node (SLN) on the basis of the anatomical location of the primary malignant melanoma on the trunk.MethodsPatients diagnosed with MM on the trunk who had undergone a SLN biopsy from January 2006 to March 2015 were identified in the Christie NHS Foundation Trust through a computer database search. The anterior and posterior surfaces of the trunk were divided into four sections each.ResultsA total of 212 patients were evaluated. MM was more common on the posterior trunk, accounting for 73% of cases, and 57% of melanomas were on the right side of the trunk. The axillary basins were involved in drainage in 91.5% of all truncal melanomas. Drainage was to a single lymphatic basin in 68.3% of cases. The incidence of drainage to multiple lymphatic basins was not uniform for the anterior and posterior surfaces of the trunks.ConclusionOne-third of MM on the posterior surface of the trunk will drain to multiple basins. Around 50% of the melanomas of the upper back drain to a contralateral basin. Independent of the location of the MM, the axillary basins were the most common location of drainage, with a total of 91% of the cohort. Therefore, the location of the SLN could be predicted, depending on the location of the MM on the trunk.
