Granuloma annulare is a benign, inflammatory skin disorder with no
distinct aetiology or widely accepted pathogenic process. Case description and
Methods: We report a case of a 71-year old female with a 4-year history of an
erythematous annulopapular lesion to the lateral aspect of her right forearm from
a pressure pleat ridge in a high-density polyethylene plastic elbow orthosis to
immobilise a prior radial head fracture. Morphological and histopathological
assessment was consistent for granuloma annulare. Findings and Outcomes: The
granuloma annulare was ameliorated after 3 months of high-potency topical
steroids under occlusive dressing. CONCLUSION: This case highlights an atypical
presentation of a pressure-induced patch of localised granuloma annulare
persisting long-term after temporary use of a high-density polyethylene orthosis
with a pleated point ridge. Special care should be taken when choosing the
appropriate orthosis in patients with sensitive skin conditions. Moulded orthoses
can have defects after manufacturing that can lead to localised skin irritation,
inflammation and subsequent rash formation. Clinical relevance Appropriate
casting and splint moulding should be taken into special consideration in
patients with sensitive skin conditions. This prevents or diminishes the chance
inducing or exacerbating skin conditions.
