Serum immunoglobulin estimation in 30 cases of cutaneous vasculitis.

Clinically diagnosed and histopathologically proved 30 cases of cutaneous vasculitis (CV) were collected from Dermatovenereology department. Serum immunoglobulins (Igs) estimation was done in all cases. Nineteen cases showed increased levels of Igs, 4 had decreased levels, while in 7 cases Igs levels remained normal. Seventeen had increase in IgG, 17 cases had in IgA and 10 in IgM and decrease in levels of IgM was seen in 3, and IgA in 2 cases. But the fluctuation in levels of Igs was statistically insignificant.
