[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.

[Nail disorders from epothilone].

We present the cases of two patients diagnosed with non-microcytic lung carcinoma who were treated with epothilone, a new chemotherapeutic agent which disrupts microtubule dynamics. The first one developed nail symptoms consisting of painful nails with a hemorrhagic appearance, which developed into significant structural disorders and onycholysis of all of the fingernails. The patient required antibiotic treatment for the associated paronychia and surgical removal of some of the nails. In the second case, asymptomatic dyschromia of the toenails appeared, with no inflammatory component. These findings show the similarity of the adverse effects of epothilone with those of the taxanes.

Localized bullous pemphigoid overlying a fistula for hemodialysis.

Two cases of bullous pemphigoid exclusively limited to the skin overlying a hemodialysis fistula in patients with chronic renal failure are reported. This is an unusual association, but should be taken into account in the differential diagnosis of bullous disorders among patients on hemodialysis. We hypothesize about the pathogenesis of this process.
