The sentinel node was located by preoperative lymphoscintigraphy (Figure 1).
(a) Abolished microarchitecture and epitheloid granulomas of the sentinel node from the left groin. Hematoxylin and eosin staining (H&E) x50. (b-d) Micrometastasis (partly single cell spread) in the lymph node. Pictures represent the same section in the lymph node.

Surprisingly, concurrent sarcoidal granulomas (Figure 2(a)) and a micrometastasis of melanoma (Figure 2(b-d)) was described in the same sentinel lymph node.18 Fluorodeoxyglucose positron emission tomography and Computed Tomography (18FDG-PET-CT) revealed multiple metabolically active mediastinal lymph nodes (Figure 3(a-c)), above and below the diaphragm, along the left iliacal vessels and in both groins.
18-Fluorodeoxyglucose positron emission tomography (PET) and Computed Tomography (CT) in transverse (a), coronal (b) and sagittal (c) images. The transverse image (a) shows multiple active lymph nodes in the mediastinum.
