Background: Nail diseases account for about 10% of all dermatological conditions. Any abnormality that affects any part of the nail unit is classified as a nail condition. The plate, matrix, bed, proximal and lateral folds, hyponychium, and underlying distal phalanx are all part of the nail unit. Heredity, skin problems, infections, systemic disease, and the ageing process, as well as internal and external drugs, physical and environmental agents, trauma, and benign and malignant tumours, can all affect these tissues. Papulo-squamous disorder is one of the main causes. Nail changes in Papulo-squamous disease have received insufficient attention, with only a few research available.
Aims & Objectives: This study attempts to shed some information on the frequency and patterns of nail involvement in Papulo-squamous illnesses.
Methodology: This is a descriptive research project. Over the course of two years, it was conducted at the dermatology department of a tertiary healthcare centre in central India. Examinations of the general, systemic, and dermatological systems were performed. The nails were meticulously examined. In pertinent cases, special examinations such as skin biopsy and potassium hydroxide (KOH) mount were performed.
Results: Papulo-squamous disorder affected 100 people. Psoriasis was the most frequent Papulo-squamous condition, followed by lichen-planus and PRP. Pitting was the most prevalent nail alteration (81%) while dorsal pterygium was the least common.
Conclusion: The nail is an important appendage that affects a variety of dermatoses and serves as a diagnostic window. Knowing the normal and abnormal variations, as well as their relationship to various Papulo-squamous illnesses, aids not only in diagnosis but also in treatment.
Key words: Papulo-squamous disorder, nail changes, psoriasis, lichen-planus.
