Abstract:
Epidermal growth factor receptor (EGFR) targeting tyrosine kinase inhibitors (TKIs) can result in significant skin toxicities that may impact patients' quality of life. While these skin reactions are well documented in patients with lighter skin, there is a paucity of literature and images to guide clinicians in their assessment in patients with darker skin tones. Given that dermatological reactions in patients with darker skin are not well represented, this can result in the undertreatment or mistreatment of these otherwise common toxicities. Herein, we present a case of a female patient with a darker skin tone with metastatic non-small cell lung carcinoma (NSCLC) with EGFR-TKI-related skin toxicity and her clinical course.
Insights
Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) can cause skin issues. This case highlights EGFR-TKI skin toxicity in a patient with darker skin tones, addressing a gap in clinical representation.
Area of Science:
- Oncology
- Dermatology
- Pharmacology
Background:
- Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are crucial in treating non-small cell lung carcinoma (NSCLC).
- EGFR-TKI therapy frequently causes dermatological toxicities, significantly affecting patient quality of life.
- Current literature and visual resources predominantly feature skin reactions in lighter skin tones, leaving a gap in understanding for patients with darker skin.
Observation:
- A case study involving a female patient with darker skin tones diagnosed with metastatic non-small cell lung carcinoma (NSCLC) is presented.
- The patient experienced skin toxicity secondary to EGFR-TKI treatment.
- The clinical course and management of this specific dermatological reaction were documented.
Findings:
- Dermatological reactions to EGFR-TKIs in patients with darker skin tones are underrepresented in medical literature.
- Lack of representation can lead to misdiagnosis, undertreatment, or mistreatment of these common toxicities.
- This case underscores the need for increased awareness and tailored clinical guidance for managing EGFR-TKI-induced skin toxicities across diverse skin tones.
Implications:
- Highlights the critical need for improved clinical recognition and management of EGFR-TKI-related skin toxicities in patients with darker skin.
- Emphasizes the importance of inclusive visual resources and literature to guide dermatological assessment and treatment.
- Advocates for equitable patient care by addressing disparities in the understanding and treatment of cancer therapy side effects.
