Introduction
Adolescence is a critical phase of transition with a myriad of hormonal changes occurring in the body to which skin reacts in various ways. They are affected by various dermatological diseases as a result of the hormonal changes and increased exposure to the external environment. They experience difficulties associated with the transition from a structured family setting to the uncertainties of adult world.
The WHO defines adolescence as the period ranging between 10 and 19 years of age. Dermatological complaints are among the common causes for out patient visits in this age group. Adolescent self-esteem is easily threatened when a highly visible skin disorder becomes the focus for unwelcome peer attention. Since adolescents constitute one fifth of the Indian population, dermatological disorders have an impact on their health- related quality of life, especially when it occurs on face leading to considerable physical and psychological morbidity.
Although there is a considerable prevalence of adolescent facial diseases, the existence of only few studies on this subject makes the planning of health actions difficult. The importance of the current study lies in the need for an epidemiological survey to acsess the prevalence of facial skin diseases in adolescents in developing countries to help implement preventive measures to decrease their prevalence.
Materials and Methods
A total of 550 adolescents in the age group of 10-19 years presenting with facial dermatoses to the outpatient department of Dermatology, Adichunchunagiri Institute of Medical Sciences, B.G. Nagara meeting the defined inclusion and exclusion criteria were enrolled in this observational cross-sectional study after taking an informed consent from the guardian (for patients <18 yrs) and approval of institutional ethical committee. A detailed history and thorough clinical examination was recorded in a structured proforma. The diagnosis was based on detailed history and thorough clinical examination, and relevant investigations were done when needed.
Study place
This study was conducted in the Department of Dermatology, Adichunchanagiri Institute of Medical Sciences Hospital and Research Centre, B.G. Nagara on an OPD basis.
Study duration
The duration of study was 18 months (1st January 2018 – 30th June 2019: 12 months for data collection and 6 months for data analysis and compilation)
Sample size
All patients meeting the below mentioned inclusion and exclusion criteria attending the OPD within the study period were included in the study.
Inclusion criteria
Adolescent patients between the age group of 10-19 years with facial dermatoses attending the Out Patient Department of Dermatology.
Adolescent patients above 18 years of age who were willing to participate in the study.(Self consent)
Parents/Guardians who gave an informed consent (for adolescent patients less than 18 Years) for enrolling their child in the study.
Procedure of study
All patients from 10 years to 19 years, satisfying the above mentioned inclusion and exclusion criteria were recruited in the study. Approval was obtained from the Institutional Ethical Committee and an informed consent was taken from the patients or their parents (for adolescent patients less than 18 years) included in the study.
After informed written consent, a detailed clinical history as per pretested and structured questionnaire including age, sex, presenting skin lesions, its onset, duration, progression, aggravating and relieving factors, past medical history, personal history followed by elaborate general and systemic examination was recorded in the standard proforma.
A detailed dermatological examination of each patient was done with emphasis on morphology, pattern and distribution of skin lesions on the face.
The diagnosis was based on detailed history and thorough clinical examination, and relevant laboratory investigations were done when needed.
Results
The observational study was conducted among 550 patients belonging to adolescent age group (10–19 years) with facial dermatoses. They constituted 7.3% of the total OPD attendance and 18.1% of the total adolescents attending the OPD during the study. The prevalence of facial dermatoses in adolescent population was 7.3.
The mean age of the sample population was 15.79 ± 2.6 years.
Out of the 550 adolescents with facial dermatoses, 346 (62.9%) were females and 204 (37.1%) were males. An overall female preponderance was seen with male to female ratio being 1:1.4.

Discussion
Skin disorders are fairly common among adolescent age group (10–19 years).1 They are affected by various dermatological diseases as a result of the hormonal changes and increased exposure to the external environment. They experience difficulties associated with the transition from a structured family setting to the uncertainties of the adult world. The impact on quality of life can be enormous during this psychologically vulnerable period of adolescence. These physiological changes that occur in the skin during puberty and adolescence have several effects, and this may also be a reason for seeking medical advice in many cases.2 There were only a single comparative study by Radhamani et al. on facial dermatoses in adolescent population.3
Prevalance
In our study, the prevalence of facial dermatoses in adolescent population was 7.3. They constituted 18.1% of the adolescents attending the OPD during the study period. Since there was paucity of similar studies, we couldn’t compare our study results.
Mean age of population
Mean age of patients in our study was 15.79 years which was similar to the study done by Radhamani et al.(16.22 years). 3
Sex distribution
In the present study, an over all female preponderance was observed with male to female ratio being 1:1.4. Our study results were similar to the study done by Radhamani et al. who also noticed a female preponderance (1:2.3).
This observation could be attributed to females being more conscious about their appearance and thus seeking medical care earlier.
Socioeconomic status
In the present study, infections and eczemas were found to have an association with the socio-economic status as per modified B.G. Prasad socioeconomic classification.4 Infections were found to be most common in lower middle (46.4%) and middle class (26.2%) of socio-economic status. Eczemas were found to be most common in lower middle (38.5%) and middle class (33%) of socio-economic status.
However the results of our study could not be compared to any other study due to paucity of similar studies.
The increased incidence of the infections and eczemas in lower socioeconomic status could be attributed to poor personal hygiene, overcrowding and lack of health awareness in the community. The increased incidence of steroid induced facies among these patients, could be due to lack of awareness and easy over the counter availability of topical corticosteroids.
Pattern of dermatoses
In our study, majority of the patients presented with acne vulgaris (34.8%) followed by infections (15.3%) and eczema (12.9%). Our study results were in concordance with study by Radhamani et al. where the most common dermatoses was acne vulgaris (20%) followed by folliculitis (16%) and pityriasis versicolor (15%).3
Acne vulgaris
In the present study, acne vulgaris was the most common dermatoses constituting 34.8% of the study population.
Of the 191 patients with acne vulgaris, 49 (25.7%) were males and 142 (74.3%) were females. Thus, acne vulgaris showed a female preponderance in our study (M:F ratio =1:3). This was in concordance with studies by Radamani et al. (M:F ratio= 1:2.3), Henshaw EB et al. (M:F ratio =1:1.3), Reddy VS et al. (M:F ratio = 1:1.01) and Kawshar T et al. (M:F ratio= 1:1.5).1, 5, 6, 7 In contrary, studies by Pandey P et al. (1.04:1) and Hmar et al. (1:1.1) reported a male preponderance.2, 8
In the present study, majority of patients had grade 1 acne – 85 (44.5%) cases followed by grade 2 – 60 (31.4%) cases, grade 3- 32 (16.8%) cases and grade 4- 14 (7.3%) cases. This was in concordance with study done by Smithard A et al. (very mild acne -22%, mild acne- 17%, moderate to severe acne- 11%).9 In contrary, study done by Krowchuk et al. observed moderate acne in 41%, severe acne in 28% and very severe in 3 % of patients.10
The spurt of acne vulgaris at adolescence could be attributed to the role of androgens, which target the sebaceous glands. At puberty, the spurt of hormones especially of androgens, stimulate sebaceous glands to secrete sebum, playing a major role in pathogenesis of acne vulgaris during this phase of adolescence.
Infections
The second most common dermatoses in our study were infections which was observed in 15.3% of the study population.
In the current study, among the infections, fungal infections were most common (8.4%), followed by viral (4.9%) and bacterial (2%) infections. However Radhamani et al. observed that bacterial infections were the most common (16%) followed by fungal (15%) and viral (6%) infections.3
Out of the 46 patients having fungal infections, tinea faciei was the most common (26 cases- 56.5%) followed by pityriasis versicolor (20 cases- 43.5%). However Radhamani et al. in their study observed pityriasis versicolor (15%) to be the most common fungal infection.3 Fungal infections showed a male preponderance in comparison to females (M:F=1.3:1).
Out of the 27 patients having viral infections, verruca plana was the most common (20 cases-74.1%) followed by molluscum contagiosum (7 cases-25.9%). This was similar to study done by Radhamani et al, who found viral warts (6%) to be the most common viral infection. Viral infections showed a male preponderance in comparison to females (M:F= 1.5:1).3
In the current study, out of the 11 patients having bacterial infections, impetigo was the most common (72.7%) followed by cellulitis (27.3%). In contrary, Radhamani et al. found folliculitis (16%) as the most common bacterial infection followed by furuncle (9%). Bacterial infections showed a female preponderance in comparison to males (M:F=1:1.2).3
Lack of health awareness, ignorance regarding diseases and failure to understand the importance of cleanliness, poor personal hygiene, poverty and overcrowding, increased exposure and enhanced outdoor activity would have been the important factors that may have contributed to higher prevalence of infections in our study.
Eczema
In the present study, seborrhoeic dermatitis (5.5%) was the most common followed by pityriasis alba (4.2%), irritant contact dermatitis (2.7%) and perioral dermatitis (0.5%). In contrary Radhamani et al. observed contact dermatitis as the most common eczema (14%) in their study. 3
Of the 71 cases of eczema, 36 (50.7%) were males and 35 (49.3%) were females. Thus in our study, eczema showed a slight male preponderance (M:F=1.03:1)
The incidence of irritant contact dermatitis in our study was 2.7% (15 cases)
Perioral dermatitis constituted 0.5% of the population. Of the 3 cases, 1(33.3%) case was a male and 2 (66.7%) cases were females, showing female preponderance (M:F=1:2).
Pigmentary disorders
In the current study, pigmentary disorders constituted 8.7% of the study. Among the pigmentary disorders, postinflammatory hyperpigmentation was most common (3.75%), followed by freckles (1.8%), lentigens (1.8%) and vitiligo (1.4%). However, due to paucity of similar studies, our study results couldn’t be compared with any other study.
An over all female preponderance was seen in comparison to males. (M:F=1:3).
This could be a consequence of postinflammatory hyperpigmentation to either acne lesions, inflammatory lesions or infective lesions, all of which were the most commonly seen dermatoses in this study.
Nevi
Nevi constituted 2.4% of the total dermatoses in our study. Congenital menalocytic nevi (0.9%) was the most common nevi followed by nevus of ota (0.7%), nevus sebaceous (0.4%) and linear epidermal veruccous nevi (0.4%). The study by Radhamani et al. found epidermal nevi as the most common nevi (8%).3 Nevi showed a female preponderance in the present study(M:F =1:5.5).
Disorder of keratinisation
Keratosis pilaris of face i.e. erythromelanosis follicularis faciei et colli was the only keratinization disorder observed with a prevalence of 2% in our study.
Of the 11 cases of keratosis pilaris on face, 4 (36.4%) cases were males and 7 (63.6%) cases were females, thus showing a female preponderance (M:F=1:1.8).
Papulosquamous disorders
In the present study, papulosquamous disorders were observed in 0.5% of the total population, and all cases (4 cases) reported were of pityriasis rosea.
Of the 3 cases of pityriasis rosea, 1 (33.3%) case was male and 2 (66.7%)cases were females, showing a female preponderance (M:F=1:2)
However the results of our study could not be compared to any other study due to paucity of similar studies
Conclusion
The prevalence of adolescent facial dermatoses in the study population was 7.3%. Infections and eczema were observed most commonly in lower middle class of socioeconomic status. Acne vulgaris was the most common dermatoses observed followed by infections and eczema.
Facial dermatoses are a major cause of emotional, personal, behavioral and social difficulties in adolescents. They even contribute to psychosocial problems including depression and low self-esteem especially in patients with acne vulgaris. Thus, it is prudent to recognize, intervene and treat facial dermatoses at the earliest to prevent the psychological sequelae. Infections were commonly seen in our study, and this could be attributed to poverty, overcrowding and poor hygiene. Proper health education to patients and families regarding the mode of spread of infections and the importance of personal hygiene is the need of the hour. Knowledge about the pattern of adolescent facial dermatoses will help us in disease control, implementation of adequate preventive strategies and in creating public awareness regarding the cause and course of various facial dermatoses.
