Summary
This study details a rare case of bullous subacute cutaneous lupus erythematosus presenting as a blistering, photosensitive rash in a patient without systemic lupus erythematosus symptoms. The condition mimicked other severe skin reactions, highlighting diagnostic challenges.
Area of Science:
- Dermatology
- Autoimmunology
- Oncology
Background:
- A 59-year-old woman with a history of autoimmune disease and disseminated uterine leiomyosarcoma developed a severe skin eruption.
- The patient's condition was characterized by a photoaggravated, blistering rash.
Observation:
- The initial rash, appearing during chemo- and radiotherapy, resembled erythema multiforme.
- Skin biopsy revealed subacute cutaneous lupus erythematosus, despite the absence of systemic lupus erythematosus signs.
- A later, photosensitive rash presented with bullae and epidermal denuding, mimicking toxic epidermal necrolysis.
Findings:
- The patient was diagnosed with bullous subacute cutaneous lupus erythematosus.
- This diagnosis was made in the absence of other systemic lupus erythematosus features.
- The case highlights a unique presentation of cutaneous lupus erythematosus.
Implications:
- This case expands the understanding of subacute cutaneous lupus erythematosus presentations.
- It underscores the importance of considering cutaneous lupus erythematosus in blistering, photosensitive eruptions, even without systemic involvement.
- The findings may aid in differentiating lupus erythematosus from other severe dermatoses.
