Introduction: Skin diseases are a major health problem in the pediatric age group.
Aim: To determine the prevalence and clinical characteristics of different pediatric dermatoses in a tertiary care centre in Kerala.
Materials and Methods: Children with age 18 years and below with clinical evidence of cutaneous disorders were studied.
Results: 500 cases were studied which showed a female preponderance of 51.4%. The most common dermatoses was infections and infestations (33.8%) followed by eczemas (32.6%), disorders of sweat and sebaceous glands (7.4%), keratinisation and paulosquamous disorders (4%). Nutritional disorders were seen in 1% of children. 3.6% had photodermatoses, 2.6% had hair and nail disorders and 0.4 % had adverse cutaneous drug reactions.
Conclusions: Fungal infection was the most common infection noted in the study, followed by viral and bacterial infection.

| Introduction|| |
Pediatric dermatology deals with diseases and skin care requirements in individuals from birth to adolescence, a relatively short period in lifetime when significant physiological, psychological, and maturity changes take place. The pattern of skin diseases is known to differ in different countries of the world and in different regions of the same country. Dermatological problems constitute at least 30% of all outpatient visits to a pediatrician and 30% of all visits to a dermatologist involve children., The prevalence of skin diseases among children in various parts of India ranges from 8.7% to 35%.
| Materials and Methods|| |
The study was conducted in the Department of Dermatology, in a Tertiary Care Center in Kerala, in 500 children attending the outpatient department. Children with age 18 years and below with clinical evidence of cutaneous disorders were included in this hospital-based descriptive study to determine the prevalence of various skin disorders and to determine clinical characteristics of different pediatric dermatoses.
All the patients were subjected to detailed history taking and meticulous examination as per the proforma after getting the informed consent. The clinical manifestations in relation to pediatric dermatoses were recorded. Detailed systemic evaluation was carried out in each case. Statistical test used was Chi-square test. The data obtained were subjected to descriptive analysis using SPSS software (Statistical software for social sciences, Version 20.0, Chicago, USA).
| Results|| |
In this study, 500 pediatric patients of age 18 and below were included. Of them, 243 (48.6%) were males and 257 (51.4%) females. Adolescent group constituted highest percentage (48%) followed by school age group, which constitutes 27.6% of total pediatric patients [Figure 1].
Infections and infestations combined constituted highest proportion 33.8% (169), followed by eczematous dermatoses which constitute 32.6% (163) [Table 1].

| Discussion|| |
The pattern of skin lesions in children is greatly influenced by climatic factors, dietary patterns, and socioeconomic status. In our study, age group of 11–18 years constituted the maximum (48%) number of pediatric patients. Sacchidanand et al. observed 5–11 years is the common age group followed by adolescents with 33.21% and 29.81%, respectively. Sharma et al. reported that pediatric dermatoses are more common in adolescent age group. Female patients outnumbered the male patients (51.4%) in our study, similar to that of Karthikeyan et al. Flavia Regina Ferreira et al. also reported female predominance (57.2%).
Infections and infestations were the most common dermatoses encountered, which were seen in 33.8% of the total cases. Our findings were similar to study by Sacchidanand et al. and Bisht et al. which showed 32.47% and 36.46%, respectively., Negi et al., Sharma and Mendiratta, and Bhatia and Ghosh et al. studies have reported them occurring in the range of 35.6–85%.,,,
Scabies alone constituted the majority of infestation, making 3.6% of the total dermatoses. Sacchidanand et al. in their study found that the incidence of scabies was 6.97%. The incidence of scabies had varied from 5.1% to 22.4% in studies done by Negi et al., Sharma and Mendiratta, and Bhatia.,, Sarkar and Kanwar in their study pointed out that the prevalence of scabies in general population of rural communities in India is about 5%. Pediculosis capitis was the next most common infestation.
Bacterial infections constituted 14.18% of the total infections and 4.2% of total pediatric dermatoses. Furunculosis was the most common bacterial infection with 38% of total bacterial infections, followed by impetigo with 28.5%, then secondary bacterial infections with 14.2% of bacterial infections. Pyodermas were the single most common dermatoses found out by Bhatia  and Ghosh et al.
Fungal infections of the skin constituted 44.59% of the total infections and 13.2% of total dermatoses. Dermatophytic infections were the most common among these infections making up to 48.5%. Tinea corporis was found in a significant number of children forming 53.12% of dermatophytic infections and 3.4% of all dermatoses followed by tinea cruris. Tinea versicolor was seen in 39.4% of total fungal infections and 5.2% of the total dermatoses. The incidence varied from 3.3 to 8.5 in various other studies.,, Among candidal infections, which constituted 12.1% of the fungal infections and 1.6% of total dermatoses, candidal intertrigo constituted 50% of all candidal infection and 0.8% of total dermatoses. Karthikeyan et al.'s study was similar to us which showed candidal infections constituted 2.1% of total dermatoses.
The viral infections constituted 40.54% of the total infections and infestations and 12% of total dermatoses of our study. Molluscum contagiosum was the most common viral disease constituting 38.3% of these infections and 4.6% of total dermatoses. Karthikeyan et al. in their study observed that incidence of molluscum contagiosum was 2.5% in children aged 1 to 15. Second most common viral infection in our study was warts, which constituted 20% of viral infections and 2.4% of total dermatoses. We observed that viral warts were more common in the adolescent group, similar to observations in previous studies., Pityriasis rosea was the next common viral infection with 16.6% of viral infections and 2% of total dermatoses in our study. Hand foot mouth disease constituted 10% of viral infections and 1.2% of total dermatoses. The incidence of Varicella was 0.4% in our study which is similar to that reported by Karthikeyan et al.

The present study recorded 1% of nutritional dermatoses which is very less as compared to other studies which reported incidence of 15.4% to 17.5%., Some studies have shown incidence from 0.45% to 2.8%., Phrynoderma was the most common among the nutritional deficiency disorders. Sacchidanand et al.'s study showed that incidence of nutritional dermatoses is 0.72%. Karthikeyan et al.'s study showed 2.8%. Awate et al. observed that the incidence of phrynoderma was 9.8%.
Eczema was the second common group of dermatoses in our study constituting 32.6% of total cases. The incidence rate of eczema in the study by Sacchidanand et al. was 20.66% whereas in Karthikeyan et al.'s study, it was 8.6%. JPD was the most common endogenous eczema, followed by pityriasis alba, nummular eczema, atopic dermatitis, and seborrhoeic dermatitis. Exogenous eczema constituted 4.3% of total dermatoses. Sacchidanand et al. reported atopic dermatitis as the most common eczematous dermatitis which constituted 6.12%. Other studies had same opinion as atopic dermatitis was the most common endogenous eczema which ranges from 3% to 28%., Pityriasis alba was second most common endogenous eczema in accordance with Saurabh Sharma et al. with incidence rate of 4.9%. Nanda et al. reported an incidence of 5.2%.
Nevoid and developmental disorders constituted 1.4% of total dermatoses in this study. Thappa  in their study observed a prevalence of 0.5%. Dogra and Kumar observed a prevalence of 1.1%. Congenital melanocytic nevus was the most common nevoid and developmental disorder in our study. Among keratinization disorders, ichthyosis was seen in 0.8%, followed by palmoplantar keratoderma and keratosis pilaris each with 0.4% prevalence and pityriasis rubra pilaris and lichen spinulosus each with 0.2% prevalence. Thappa observed the prevalence of ichthyoses and palmoplantar keratoderma in 2.1% of cases, which is similar to our study. In contrast, Ghosh et al. did not encounter any of these disorders in their studies. In the study conducted by Dogra and Kumar, the prevalence was 1.3%.
Papulosquamous disorders were noted in 2% of the cases during this study period. Prevalence of papulosquamous disorders in the study of Sacchidanand et al. was 6.08%. In accordance with Sacchidanand et al., among the papulosquamous disorders, psoriasis was the most common dermatoses and constituted about 4.28% of the total dermatoses. Karthikeyan et al. reported prevalence of psoriasis as 1.4%. In a prospective study from Kuwait, psoriasis was seen in 4%.
Sweat and sebaceous gland disorders constituted 7.4% of dermatoses during this study period. Acne was the most common among them with prevalence rate of 5.6%, followed by miliaria with 1.2%. In the study done by Karthikeyan et al., the prevalence of miliaria was 4.1%. Tamer et al. showed 12.4% prevalence while Rajar et al. reported a prevalence of 26% in the age group of 11–15 years.
Vesiculobullous disorders constituted 0.6% of total dermatoses with two cases of epidermolysis bullosa simplex and one case of chronic bullous dermatoses of childhood. According to Sarkar et al., the prevalence rate of epidermolysis bullosa simplex was 4.65%. Connective tissue disorders constituted 0.6% of dermatoses in this study. Dogra and Kumar reported an incidence of 0.09% in their study among schoolchildren in Northern India. Karthikeyan et al. reported that 0.5% of dermatoses were connective tissue disorders.
Pigmentary disorders constituted 1% of total dermatoses in our study. Vitiligo and freckles were 0.4% each and postinflammatory hyperpigmentation in 0.2%. Sacchidanand et al. reported that pigmentary disorders constituted 5.81% and Karthikeyan et al. reported 5.7%. Abnormal response to light was seen in 4.2% of total cases in our study. Polymorphic light eruption was the most common among them with 3.6%, followed by porphyrias in 0.4% and xeroderma pigmentosum was seen in 0.2%.
Hair and nail disorders constituted 4% of cases in this study. Telogen effluvium was the most common hair disorder noted in this study, followed by alopecia areata, premature canities, and trichotillomania. Paronychia was the most common nail disorder. Thappa reported 5.2% prevalence of hair and nail disorders in their study. Vora et al. observed alopecia in 0.07%, premature canities in 0.02%, nail changes in 0.07%, and paronychia in 0.02%.
Toxic epidermal necrolysis due to lamotrigine and 1 patient had maculopapular rash due to amoxicillin constituted 0.2%. Sacchidanand et al. reported adverse drug reactions in 0.72% of patients. Miscellaneous conditions constituted 17.6% of study population. Insect bite reaction contributed to 46.5% of these disorders.
Our study had few limitations. It was conducted in a single center and sample size was small. No laboratory tests were done for conformation. A large, prospective multicentric study needs to be conducted to know more about pediatric dermatoses.
| Conclusions|| |
The present study was undertaken to determine the characteristic clinical pattern and prevalence of pediatric dermatoses. The majority of the study population (48%) belonged to adolescent age group. Of them, females outnumbered males. Fungal infections were the most common infection noted in the study, followed by viral and bacterial infections. ACD was the most common exogenous eczema and JPD was the most common endogenous eczema. Plaque psoriasis was the most common papulosquamous disorder, followed by lichen planus. Acne was the most common sweat and sebaceous gland disorder with female preponderance. Telogen effluvium was the most common hair disorder, followed by alopecia areata. Paronychia was the most common nail disorder.
A detailed knowledge about the pattern of pediatric dermatoses in each geographic area will help us in implementing essential changes in health education, disease control, and preventive strategies in the area concerned.
