Non infective bullous lesions: a diagnostic challenge in a minimally equipped centre- based solely on microscopic findings|
Garg, Rashi & Bhojani, Kaushal
Vesicobullous lesions of skin may occur in different forms of dermatosis, which include various inflammatory, infective,
autoimmune, drug induced as well as genetic conditions. Autoimmune bullous lesions, may be fatal if not treated with appropriate agents. Bearing in mind, the morbidity of these diseases, it is important to establish a firm diagnosis. A diagnostic
skin biopsy with immunofluorescence is frequently used to confirm a clinical diagnosis, especially where it is not apparent
clinically. There are many centres in India where immunofluorescence is not available and the diagnosis in these lesions
is based on clinical and histopathological features only. Here in this study, we studied 53 skin punch biopsies with clinical
suspicion of vesicobullous lesions followed by histopathological examination was carried out over a period of 2 years in a
Medical College in Gujarat. Lesions were categorised based on the location of the blister. 1) Suprabasal 2) subcorneal 3)
and subepidermal. Further subtyping was done based on additional histopathological features and clinical correlation. All
the patients responded appropriately to the treatment and the results correlated well with the immunofluorescence done in
a few cases. This study lays emphasis upon the histopathology and clinical features keeping in consideration of the lack of
ancillary techniques in many centres especially in the developing world.
