Etretinate can cause skin dryness and hair thinning. This study reports a rare case of cutaneous porphyria in a renal transplant patient due to etretinate, highlighting a potential photosensitivity risk.

Area of Science:

Dermatology
Nephrology
Pharmacology

Background:

Etretinate is a retinoid medication used for various skin conditions.
Known side effects include skin dryness, pruritus, and hair thinning.
Photosensitivity is a rarely reported adverse reaction to etretinate.

Observation:

A renal transplant recipient developed cutaneous porphyria.
The patient was prescribed etretinate to manage cutaneous neoplasia.
This occurred despite photosensitivity being a rare side effect.

Findings:

The development of cutaneous porphyria lesions was linked to etretinate use.
This case highlights a severe photosensitivity reaction.
The patient's underlying condition was cutaneous neoplasia.

Implications:

Clinicians should be aware of the potential for severe photosensitivity reactions with etretinate.
Monitoring for porphyria symptoms is crucial in patients on etretinate, especially transplant recipients.
This finding expands the known adverse effect profile of etretinate.
