Summary
This study details a rare case of granulocytopenia and dermatitis caused by cyanamide treatment for alcoholism. Prompt treatment with granulocyte colony-stimulating factor led to recovery, highlighting cyanamide
Area of Science:
- Toxicology
- Dermatology
- Hematology
Background:
- Cyanamide is used to treat alcoholism.
- Adverse drug reactions can manifest in various ways.
Observation:
- A 64-year-old male developed scaly erythema and severe granulocytopenia after one month of cyanamide treatment.
- Bone marrow examination revealed granulocyte maturation arrest.
Findings:
- Cyanamide was identified as the causative agent through drug lymphocyte stimulation and patch testing.
- Treatment with granulocyte colony-stimulating factor and cessation of cyanamide resulted in clinical improvement and increased granulocyte counts.
Implications:
- This is the first reported case of cyanamide-induced granulocytopenia.
- Highlights the importance of considering drug-induced toxicity in patients presenting with cytopenias and dermatological symptoms.
- Suggests potential diagnostic value of lymphocyte stimulation and patch testing for cyanamide hypersensitivity.
