Sentinel lymph node biopsy for conjunctival malignant melanoma: surgical techniques
BACKGROUND The purpose of this report is to examine the viability and safety of preoperative lymphoscintigraphy and radio guided sentinel lymph node (SLN) biopsy for conjunctival melanoma, and to identify the best technique to perform this procedure. METHODS Three patients diagnosed with malignant melanoma of the conjunctiva underwent lymphoscintigraphy and SLN biopsy using a dual technique c...
متن کاملSentinel lymph node biopsy correctly predicts regional lymph node recurrence in trunk malignant melanoma with multiple drainage basins
We report a young male with an initial excisional biopsy report of melanoma of the lower back, referred to our hospital for complete excision and sentinel lymph node (SLN) biopsy. Four peritumoral intradermal Tc-99m phytate injection was performed and SLNs were detected in both axillary and right inguinal regions. On the biopsy only the right axillary SLN was metastatic leading to right axilla...
متن کاملProspective study of sentinel lymph node biopsy for conjunctival melanoma
BACKGROUND To report our experience with sentinel lymph node biopsy for staging patients with conjunctival melanoma. METHODS A prospective review of patients with conjunctival melanoma who underwent sentinel lymph node biopsy at St Bartholomew's Hospital from May 2008 to May 2012. The selection criterion for sentinel node biopsy depended on the tumour thickness (≥2 mm) and location of the con...
متن کاملSentinel-lymph-node biopsy for cutaneous melanoma.
Results: Positive SLNs were detected in 39 (15%) of 260 cases, including 0 (0%) of 45 for cutaneous melanomas 1.0 mm thick or less (T1), 21 (18%) of 115 for melanomas 1.01 to 2.0 mm thick (T2), 12 (19%) of 64 for melanomas 2.01 to 4.0 mm thick (T3), and 5 (16%) of 32 for melanomas thicker than 4.0 mm (T4). Median Breslow depths were 1.89 mm for SLN-positive biopsy specimens and 1.50 mm for SLN-...
متن کاملRadioguided sentinel lymph node biopsy in malignant cutaneous melanoma.
The procedure of sentinel lymph node biopsy in patients with malignant cutaneous melanoma has evolved from the notion that the tumor drains in a logical way through the lymphatic system, from the first to subsequent levels. As a consequence, the first lymph node encountered (the sentinel node) will most likely be the first affected by metastasis; therefore, a negative sentinel node makes it hig...
