M. Inaoki et al., Pemphigus foliaceus developing after metastasis of cutaneous squamous cellcarcinoma to regional lymph nodes, J AM ACAD D, 45(5), 2001, pp. 767-770
We describe a patient in whom pemphigus foliaceus development after utaneou
s squamous cell carcinoma (SCC) metastasized to regional lymph nodes. Immun
ologic analysis revealed that production Of antidesmoglein 1 autoantibodies
started when SCC metastasized, and the SCC expressed desmoglein 1, suggest
ing a pathogenic role of metastasized SCC in developing pemphigus foliaceus
.
