Abstract:
Sentinel lymph node biopsy (SLNB) is a prognostic tool used in cases of melanoma with a stage IB or greater and the absence of clinical lymphadenopathy. A positive SLNB historically indicated a need for regional lymph node clearance. However, cases of clinical lymphadenopathy in the presence of primary melanoma negates the use of SLNB and rather the British Association of Dermatologists advocate a primary block dissection of regional lymphatic tissue [NICE UK. Melanoma: assessment and management. NICE Guideline NG 14. 2015]. The following describes the case of a patient with an original stage II melanoma and a concurrent diagnosis of B cell lymphoma associated with widespread lymphadenopathy. Our multi-disciplinary team believe the use of SLNB is a more informative investigation compared with ultrasonograpphy and fine needle aspiration for such cases. In cases of clinical uncertainty due to a dual diagnosis of lymphoma, cytology would not provide nodal morphology or histological architecture, required for lymphoma grade and subtype.

Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
