Signet-ring squamous cell carcinoma: a report of a rare variant and review of the literature
Published Web Locationhttps://doi.org/10.5070/D3265048777
Signet-ring squamous cell carcinoma is a rare histological subtype of squamous cell carcinoma. The distinct morphologic appearance of this variant can mimic metastatic adenocarcinoma and impose a diagnostic challenge. Unlike its glandular counterpart, signet-ring cell variant of squamous cell carcinoma has a poorly characterized histopathogenesis with no known prognostic implication. We describe an additional case and review the literature.
