Skipped sentinel lymph node basin in a patient with forearm cutaneous melanoma: A case report

Oncol Lett. 2024 Mar 26;27(5):233. doi: 10.3892/ol.2024.14366. eCollection 2024 May.ABSTRACTSentinel lymph node biopsy is an important tool in the management of malignant melanoma, particularly in predicting micrometastasis to regional lymph nodes. Cases of secondary drainage to lymph nodes outside of conventional nodal basins and overall unusual lymph node localization have been reported. The present study reports a unique case of a 'skipped sentinel lymph node basin' pattern in a patient with a right forearm malignant melanoma. Lymphatic mapping using cutaneous lymphoscintigraphy revealed localization at the right supraclavicular lymph node, bypassing right axilla localization despite no prior axillary dissection or previous surgery or radiation. This unique pattern outlined in the present report adds to our understanding of disease localization and unique presentations.PMID:38586207 | PMC:PMC10996031 | DOI:10.3892/ol.2024.14366
