Clinical and contact allergological observations on hand eczema: a descriptive study

Area of Science:

• Dermatology
• Allergology

Background:

• Hand eczema (HE) presents diagnostic challenges for patients and physicians.
• Understanding HE's frequency, clinical patterns, and triggers is crucial for effective management.

Purpose of the Study:

• To determine the frequency and clinical characteristics of hand eczema.
• To correlate atopy and contact sensitization with specific clinical features of HE.

Main Methods:

• A study included 61 patients diagnosed with hand eczema over one year.
• Patch testing was performed on 47 patients to identify contact sensitizers.

Main Results:

• Hand eczema occurred in 0.57% of cases.
• Pompholyx was the most common morphological type; endogenous eczema was the most frequent etiological type.
• Contact allergy was identified in 55.3% of patients, with nickel sulfate being the most common sensitizer (18.5%).

Conclusions:

• Endogenous factors and pompholyx are key features of hand eczema.
• Contact allergens, though not always directly linked to specific morphological types, can exacerbate or prolong hand eczema.
• Identifying contact allergens is important for managing persistent or recurrent hand eczema.
