Indeterminate cell histiocytosis treated successfully with 2-chlorodeoxyadenosine

Area of Science:

• Dermatology
• Oncology

Background:

• Indeterminate cell histiocytosis (ICH) is a rare Langerhans cell-related disorder.
• Generalized papular eruption is a characteristic manifestation of ICH.

Observation:

• A 54-year-old male presented with a decade-long history of generalized papular eruption.
• The clinical presentation was consistent with indeterminate cell histiocytosis.

Findings:

• The patient received a course of 2-chlorodeoxyadenosine (2-CdA).
• Favorable response to 2-chlorodeoxyadenosine treatment was observed.

Implications:

• 2-chlorodeoxyadenosine demonstrates potential efficacy in managing indeterminate cell histiocytosis.
• This case highlights a viable treatment strategy for patients with generalized papular eruptions due to ICH.
