[Paraneoplastic palmar erythema].

Area of Science:

• Dermatology
• Oncology

Background:

• Palmar erythema is a skin condition characterized by redness of the palms.
• Its association with various systemic diseases is documented, but its link to neoplastic conditions requires further investigation.

Observation:

• A case of symmetric palmar erythema with chronic evolution preceding subclinical gastric adenocarcinoma metastasis is presented.
• Clinical presentation and iconography were similar to a previously reported case associated with Hodgkin disease.

Findings:

• The study suggests a potential association between palmar erythema and occult malignancies.
• Review of literature reveals limited references connecting palmar erythema to neoplastic diseases.

Implications:

• Systematic oncological screening is recommended for patients presenting with palmar erythema of unknown etiology.
• Early detection of cancer through dermatological signs may improve patient outcomes.
