Abstract:
The accuracy and sensitivity of both direct and indirect immunofluorescence microseopy in diagnosing chronic bullous dermatoses were evaluated and compared in 11 cases of six different disease entities(pemphigus vulgaris, pemphigus vegetans, bullous pemphigoid, linear IgA bullous dermatosis, familial benign chronic pemphigus), which had been diagnosed clinically and by routine histopa thological studies. And the results obtained were as follows: 1) In 4 cases of bullous pemphigod, the direct IF of perilesional skin showed linear deposition of IgG and C2 along basement membrane zone(BMZ), whereas the indirect IF revealed negetive findings. 2) In 2 cases of pemphigus vulgaris, the direct IF showed deposition of IgG and C2 in intercellular substance(ICS) of perilesional epidermal tissue, and the indirect IF revealed auto-antibody to ICS(1:320) in one case. 3) In 2 cases of linear IgA bullous dermatosis, which were diagnosed as dermatitis herpetiformis by clinical and routine hisopathological findings, the direct IF of perilesional and uninvolved skin manifested linear deposition of IgA, IgM, C3 and F along BMZ, However, no immunofluorescence was detected by the indirect IF. 4) In a case of chronic bullous dermatosis of childhood, the direct IF of perilesional skin showed linear deplosition of IgA and IgM along BMZ. 5) In a case of pemphigus vegetans, the direct IF revealed no specific findings, while the inderect IF disclosed auto antibody positive to ICS(1:40). 6) In a case of familial benign chronic permphigus, no immunofluorescence was found by direct IF. These results indicate that both direct and indirect immunofluorescence micros-copy are valuable in diagnosing chronic bullous dermatoses and in understanding their immune pathogenesis.
