Abstract:
Sorafenib is a multikinase inhibitor increasingly used for the treatment of several solid tumors. Different types of keratotic lesions, such as squamous cell carcinoma, actinic keratosis, or infundibular cyst, have been reported in association with this therapy. We present a 15-year-old male diagnosed with desmoid fibromatosis who developed multiple penile and scrotal infundibular cysts while receiving treatment with sorafenib.
Insights
Sorafenib treatment for desmoid fibromatosis in a 15-year-old male led to the development of multiple infundibular cysts on the penis and scrotum. This highlights a rare side effect of this multikinase inhibitor therapy.
Area of Science:
- Dermatology
- Oncology
- Pharmacology
Background:
- Sorafenib is a multikinase inhibitor used to treat various solid tumors.
- Previous reports have documented keratotic lesions, including squamous cell carcinoma and actinic keratosis, associated with sorafenib therapy.
- Infundibular cysts are also a known, albeit less common, potential adverse effect.
Observation:
- A 15-year-old male patient with desmoid fibromatosis was undergoing treatment with sorafenib.
- The patient developed multiple infundibular cysts.
- These lesions were located on the penile and scrotal regions.
Findings:
- The development of multiple penile and scrotal infundibular cysts was observed in a young male patient during sorafenib treatment for desmoid fibromatosis.
- This case adds to the spectrum of dermatological side effects associated with sorafenib.
- The specific presentation of multiple genital infundibular cysts is noteworthy.
Implications:
- Clinicians should be aware of the potential for genital infundibular cyst formation as a side effect of sorafenib.
- This finding may prompt further investigation into the mechanisms underlying sorafenib-induced adnexal lesions.
- Monitoring for and managing these dermatological adverse events is crucial for patient care during sorafenib therapy.
