Waxy nodule on the nasal ala post-trauma: clinical presentation and surgical resolution

Primary cutaneous nodular amyloidosis is a rare type of amyloidosis where the deposition of amyloid is limited to the skin, and unlike macular or lichenoid amyloidosis, traumatic epidermal damage is not believed to play an etiopathogenic role. Must be studied and followed-up, because it is associated with Sjögren’s syndrome and progression to systemic amyloidosis has been reported. Dermoscopy findings are yellow-orange background, bright white lines, and linear and serpiginous telangiectasias. The treatment is surgical excision, although various treatment options have been described. We report a unusual case of primary cutaneous nodular amyloidosis secondary to local trauma on the nose.
