BACKGROUND: Acantholysis in pemphigus vulgaris (PV) and pemphigus foliaceus (PF) occurs predominantly in the suprabasal area and the granular layer, respectively. However, acantholysis can occasionally be observed in unusual locations.
METHODS: We retrospectively studied the acantholysis locations in 35 PV and 27 PF cases, and analyzed them using the index value of Desmoglein (Dsg) 1 and Dsg3 by enzyme-linked immunosorbent assay, clinical data, and inflammatory cells. We also analyzed the relationship between clinical subtype and various parameters.
RESULTS: In PV, acantholysis was noted in the suprabasal area in 3 cases, in the lower half of the epidermis in 19 cases, and throughout the epidermis in 13 cases. In PF, acantholysis was observed in the granular layer in 6 cases, in the upper half of the epidermis in 14 cases, and throughout the epidermis in 7 cases. Mean index value of Dsg1 in PV patients with acantholysis throughout the epidermis was 2-fold higher than other PV patients. Neutrophils tended to infiltrate the dermis and epidermis more in PF than in PV.
CONCLUSIONS: Higher Dsg1 index values seem to correlate with acantholysis in the upper part of the epidermis in PV. Neutrophils may play some role in unusual acantholysis locations in PF.
