| description | Introduction: Differentiation between Chronic Hand Eczema
(CHE) and Palmoplantar Psoriasis (PP) is a diagnostic challenge.
Dermoscopy can help to distinguish between the two conditions.
Aim: To establish and compare the dermoscopic findings of the
CHE and PP using DermLite DL4 dermoscope and to confirm the
accuracy of the dermoscopic findings with the histopathological
findings.
Materials and Methods: A cross-sectional study was conducted
at Navodaya Medical College, Hospital and Research Centre,
Raichur, Karnataka, India, from January 2017 to June 2018. Fifty
patients each of CHE (26 male and 24 female subjects) and PP (25
male and 25 female subjects) were included in the study. A detailed
clinical history, cutaneous clinical and dermoscopic findings of
each case were noted. A 4 mm punch biopsy was taken from 30
patients for histopathological analysis. The data was tabulated,
analysed and tested for significance using the Chi-square test.
Results: The mean age of the patients was 46±4 years. On
dermoscopic examination, diffuse white scales in 45 (90%)
patients, over a red background in 49 (98%) patients with
regularly arranged dots and globules in 45 (90%) patients
was seen in PP. Patchy yellow scales 46 (90%), yellow
dots, globules and yellow to brown crusts against a yellow
background was seen in all patients (100%) of CHE (p-value
<0.001). Histopathological findings are in agreement with
dermoscopic findings in 9/16 and 10/14 cases of CHE and PP
respectively.
Conclusion: Dermoscope is a useful non invasive clinical aid
to differentiate between CHE and PP. The presence of diffuse
white scales over a red background and regularly arranged
vessels indicates PP, whereas the presence of patchily
distributed yellow scales, yellow dots and globules; and
yellow to brown crusts against a yellow background is more
suggestive of CHE. |
