Generalized vitiligo after erythroderma.

Area of Science:

• Dermatology
• Oncology
• Internal Medicine

Background:

• Erythroderma and vitiligo are distinct dermatological conditions.
• Prostate adenocarcinoma is a common malignancy in older men.
• The association between these conditions and malignancy is rarely reported.

Observation:

• A 65-year-old man presented with erythroderma of unclear etiology.
• Generalized vitiligo developed six weeks after the onset of erythroderma.
• Evaluation revealed an underlying prostate adenocarcinoma.

Findings:

• This is the first reported case of vitiligo following exfoliative dermatitis.
• The patient exhibited two uncommon markers of internal malignancy: erythroderma and vitiligo.
• Both erythroderma and vitiligo were observed concurrently with prostate adenocarcinoma.

Implications:

• This case suggests a potential, though rare, association between erythroderma, vitiligo, and prostate adenocarcinoma.
• Highlights the importance of investigating underlying malignancies in patients presenting with unusual dermatological manifestations.
• Underscores the need for further research into the paraneoplastic potential of dermatological conditions.
