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).
