Bleomycin-Induced Flagellate Dermatitis

Case report: a cataract induced by bleomycin in a patient with testicular cancer

Background

Bleomycin is a glycopeptide antibiotic with outstanding anti-tumor effects. A major adverse effect of bleomycin is lung fibrosis. However, the development of cataracts as a severe adverse effect has not been reported.

Case summary

Herein, we describe the first case of cataract induced by bleomycin therapy in a 22-year-old male with testicular cancer. After surgical intervention and following five successive chemotherapy cycles of the BEP regimen, including bleomycin, etoposide and cisplatin, the patient reported a gradual painless loss of vision, with substantial decline in visual ability, especially in the right eye. Following comprehensive eye examinations, a cataract was diagnosed. Eventually, the patient underwent phacoemulsification and received replacement of the intraocular lenses.

Conclusion

Bleomycin can cause cataracts, which induces a significant loss of vision. Therefore, clinicians should observe early symptoms and properly adjust treatment to prevent aggravation of symptoms.

A Danish case of bleomycin-induced flagellate erythema

Patients who are undergoing treatment with bleomycin and develop prurigo or rash should be suspected of bleomycin-induced flagellate erythema and treated early with antihistamines, topical, and oral corticosteroids.

The diverse methods of bleomycin delivery in cutaneous warts: A literature review

Bleomycin is a useful treatment option for recalcitrant verrucae. Several different methods of bleomycin delivery have been described, including intralesional injection, intralesional injection combined with laser, microneedling, multiple puncture and adhesive tape. We reviewed the literature to evaluate the various methods of bleomycin administration to treat warts, including the different doses, instruments and procedures used. Intralesional injection (cure rate ranged from 67.8% to 99.23%) and topical bleomycin with multipuncture or microneedling methods (63.6% to 100%) were found to be effective in the treatment of warts. Overall, pain is significantly less with microneedling and multipuncture techniques compared with intralesional injection. Bleomycin injection combined with pulsed dye laser, electroporation, or by other methods, such as, microneedle patches or adhesive tape do not seem to be more beneficial than bleomycin administered by intralesional injection, multipuncture or microneedling techniques.
