[Pseudovascular squamous cell carcinoma].
The adenoid form of squamous cell carcinoma is a neoplasm that is characterized by the fact that it presents a pseudoglandular pattern in the histological study. The biological phenomenon that explains this histological pattern is acantholysis; when the latter is massive, the tumor may even mimic a vascular proliferation, and is known as pseudovascular squamous cell carcinoma. This tumor has the clinical characteristics of a squamous cell carcinoma, but histologically, it may mimic an angiosarcoma. Most cases of pseudovascular squamous cell carcinoma of the skin have a poor prognosis.
