Why This Matters

LCH can present like perianal Crohn's disease and may be missed if biopsies and molecular testing are not performed. Correct diagnosis changes treatment and prompts systemic staging for other malignancies.

Who Should Pay Attention

Clinicians treating refractory perianal/colonic disease; adult IBD patients with atypical or non-healing perianal lesions; gastroenterologists and colorectal surgeons.

What To Know

This case report describes an woman in her early 80s with chronic anal fissures concerning for perianal Crohn's disease; colonoscopy and biopsies showed LCH confirmed by BRAF V600E mutation. Systemic staging found unrelated breast and kidney malignancies. The patient received cladribine chemotherapy with resolution of LCH lesions and symptoms.

Histology and molecular profiling were key to diagnosis and to guide therapy.
