Figure 1: AB) MRI showing a metastatic lesion of the neck with histology from primary lesion. Coronal contrast-enhanced T1-weighted MRI slices show the enhancing lesion of the left posterolateral neck (asterisks). The lesion’s location, encroaching on sternocleidomastoid musculature and prevertebral fascia, correlates with clinical symptoms of neck pain with lateral movement. CD) CT scan parasagittal and coronal view confirmed the presence of the mass (asterisk) and how it infiltrates surrounding structures. The round circle indicates norma lymph node.
Figure 2: Histology 200x magnification. A) Incisional biopsies of the left sternocleidomastoid muscle and superficial cervical fascia. Hematoxylin-eosin staining shows histological features suggestive of infiltrating gastric carcinoma (G2). B) Immune histochemistry with CKAE1/AE3 shows positive nuclear coloration indicative of cancer. C) Eosin and hematoxylin staining of gastric tissue from endoscopy shows classic histology of signet-ring cell carcinoma with characteristic signet-ring cell vacuoles (black arrow).
