Life-threatening bleeding from gastric mucosal angiokeratomas during anticoagulation: A case report of Fabry disease

Rationale: Angiokeratomas are the earliest manifestation of Fabry disease (FD), and the extent of their appearance is related to disease severity. Angiokeratomas are mostly found on cutaneous regions. Patient concerns, diagnoses, interventions, and outcomes: Here we report an FD patient with widespread gastrointestinal angiokeratomas who developed life-threatening bleeding following anticoagulation for atrial fibrillation. Lessons: Careful observation for gastrointestinal bleeding is warranted for patients on anticoagulation with extensive cutaneous angiokeratomas. Furthermore, our experience suggests that surveillance is needed to assess the prevalence and extent of gastrointestinal angiokeratomas in patients with FD.
