Multifocal aggressive squamous cell carcinomas induced by prolonged voriconazole therapy: a case report
1Department of Dermatology, CHU Caen, Avenue Georges Clémenceau, 14033 Caen, France.
Case Reports in Medicine
|January 7, 2011
Summary
Prolonged voriconazole treatment for fungal infections may lead to skin reactions and potentially skin cancer. This case highlights a patient developing multiple squamous cell carcinomas, suggesting a link between voriconazole and skin carcinogenesis.
Area of Science:
- Dermatology
- Mycology
- Oncology
Background:
- Voriconazole is a crucial antifungal medication for severe fungal infections.
- Prolonged voriconazole use is associated with skin reactions, including photosensitivity.
- Emerging evidence suggests a potential role for voriconazole in skin carcinogenesis.
Observation:
- A 55-year-old male with pulmonary aspergillosis developed a phototoxic reaction after starting voriconazole.
- The patient subsequently developed multiple squamous cell carcinomas on sun-exposed skin.
- No new carcinomas appeared after voriconazole discontinuation; EBV and HPV were negative.
Findings:
- The case strongly suggests voriconazole's imputability in the development of multiple, aggressive squamous cell carcinomas.
- Genetic analysis revealed two variants in the MICR gene in the affected patient.
- A multifactorial hypothesis involving voriconazole, immunosuppression, and host genetics is proposed.
Implications:
- Voriconazole therapy necessitates strict photoprotection measures and regular skin monitoring for patients.
- This case underscores the importance of vigilance for potential oncogenic risks associated with long-term antifungal treatment.
- Further research is warranted to elucidate the mechanisms linking voriconazole to skin cancer development.

01:20Candidiasis
Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
01:24Drugs for Peptic Ulcer Disease: Sucralfate as Mucosal Protective Agents
In the intricate landscape of the gastric lumen, excessive acid secretion disrupts the natural defense mechanisms, weakening the mucus-bicarbonate barrier. This vulnerability allows pepsin to infiltrate epithelial cells, digesting mucosal proteins and triggering erosion, leading to ulcer formation.
In this scenario, mucosal protective agents like sucralfate play an essential role. Sucralfate, a complex of sulfated sucrose and aluminum hydroxide, demonstrates its usefulness in acidic conditions,...

01:21Barrett Esophagus-II: Clinical Manifestations and Management
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...

01:15Antifungal Agents
Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
02:56Treatment Resistent Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
