Detailed primary localised cutaneous nodular amyloidosis clinical and pathological workup.

Primary localised cutaneous nodular amyloidosis is a rare form of amyloidosis characterised by amyloid deposition in the skin but a lack of further organ involvement; therefore, it is not a systemic disease that progresses to complication. Limited knowledge exists on the causes and outcomes of long-term cutaneous nodular amyloidosis patients. This study reports a case of a woman in her late 80s presenting with a primary cutaneous nodular amyloidosis, with yellow, white plaques and a focal area of violaceous nodules along the inferior lumbar spine.
