Study of Lichen Planus and its different types andassociated conditions

Abstract

Lichen planus is associated with significant morbidity because of the severe itching that most of the patients suffer from and also due to post-inflammatory pigmentation seen at the site of lesions that is quite
resistant to treatment. Even though lichen planus has been described as self-limiting disease, it has been shown that the recurrences in the disease are quite common. Another cause of concern is the development
of squamous cell carcinoma in few cases of oral lichen planus and hypertrophic lichen planus. 
Objectives of the study are;
1. To study different clinical types of lichen planus.
2. To study association of lichen planus with other diseases
3. To study histological features in different clinical types of lichen planus
After taking history, a thorough general physical examination was done to look for any other associated
abnormalities. Systemic examination was done in all cases to look for any systemic abnormalities which
were noted. Cutaneous examination was done with regard to the morphology of the lesions, configuration
of the lesions, distribution of the lesions, presence or absence of Koebner’s phenomenon. Oral mucosa,
genital mucous membrane & nails were examined to look for any associated lesions. In our study no
association of lichen planus was seen with hepatitis C, hepatitis B and liver abnormalities. Diabetes mellitus
and hypertension were common associated systemic disease, while alopecia areata and vitiligo were
associated cutaneous disorders.
