Summary
A rare toxic epidermal necrolysis (TEN) reaction occurred in a patient treated for chronic lymphatic leukemia (CLL) with chlorambucil. This severe skin condition, confirmed by patch testing and biopsy, highlights the need for vigilance with this chemotherapy agent.
Area of Science:
- Dermatology
- Oncology
- Pharmacology
Background:
- Chronic lymphatic leukemia (CLL) is a common hematologic malignancy.
- Chlorambucil is an alkylating agent used in CLL treatment.
- Cutaneous reactions can be adverse effects of chemotherapy.
Observation:
- A patient undergoing chlorambucil treatment for CLL developed a severe skin reaction.
- The reaction presented as confluent maculopapular erythema and large flaccid bullae on the trunk, limbs, and mucous membranes.
- The patient also experienced a fever of 38°C.
Findings:
- Toxic epidermal necrolysis (TEN) was suspected based on the clinical presentation.
- Diagnosis of TEN was confirmed through a positive skin patch test.
- A subsequent cutaneous biopsy further supported the TEN diagnosis.
Implications:
- This case highlights a rare but serious adverse drug reaction to chlorambucil.
- Physicians should consider TEN in patients with CLL experiencing severe cutaneous reactions during chlorambucil therapy.
- Early recognition and diagnosis of drug-induced TEN are crucial for patient management.
