Objectives: To study the spectrum and have a clinicopathological correlation of papulosquamous skin
lesions.
Material and Methods: A series of noninfectious papulosquamous skin lesions coming to Department
of Dermatology were studied over a period of one year, i.e. from June 2017 to July 2018. These were
correlated and analysed with the histopathological findings.
Results: The present study comprised of 70 cases of skin diseases presenting as papulosquamous lesions.
Majority of cases were in the age group of 31 to 40 years (16 cases, 22.8%) followed by 11 to 20 years
(15 cases, 21.4%). Females were more commonly affected with 37 cases(52.8%) compared to males with
33 cases (47.1%) and female to male ratio of incidence being 1:0.89.
In the present study, out of 70 cases, 34 cases (48.5%) were diagnosed as psoriasis, Lichen planus-
15 cases(21.4%), Chronic Dermatitis- 4 cases (5.71%), Lichen striatus- 3 cases (4.28%), Pityriasis
Lichenoides- 2 cases(2.85%), Pityriasis Rosea- 2 cases (2.85%), Prurigo Simplex- 2 cases(2.8%), Prurigo
Nodularis and Lichen Nitidus 1 case each, 1 case each of atopic eczema, contact dermatitis and chronic
actinic dermatitis and inconclusive cases being 3.
The histopathological findings of psoriasis and lichen planus were studied with special emphasis. The
predominant histopathological finding in psoriasis is acanthosis and the predominant histopathological
finding in lichen planus was band like infiltrate in the dermoepidermal junction. These findings in addition
to other specific findings and clinical correlation were used to give a conclusive diagnosis.
There were 4 cases of psoriasis, 2 cases of lichen planus, 2 cases of 1 case of, 1 case of which did not
correlate with histopathological findings.
Conclusions: In our study females were mostly affected. The age group mainly affected was 31-40 years.
Psoriasis was the commonest papulosquamous lesion. Good clinicopathological correlation is very much
necessary for diagnosis.
