Background And Aims: Pulmonary amyloidosis is usually associated with systemic amyloidosis. Localized pulmonary amyloidosis without systemic amyloidosis is even rare. We reported a rare case of multinodular pulmonary amyloidosis to improve the understanding of the disease.
Methods: Report of a case.
Results: We present an unusual case of primary pulmonary multinodular amyloidosis in a middle-aged woman. She presented our hospital with cough and chest distress only. Results of computed tomography (CT) showed multiple nodules with diffused calcification and thick-walled cavity in bilateral lung parenchyma. And the diagnosis of nodular amyloidosis was established by a CT-guided core needle biopsy.
Conclusions: The case clearly shows it is difficult to distinguish parenchymal nodular amyloidosis from malignant primary lung neoplasm in radiology because of their similar images. Thus, the role of CT-guided core needle biopsy in diagnosis of pulmonary multinodular amyloidosis is very important.

Improving prognostic evaluations in patients with stage IIIb light chain cardiac amyloidosis: role of haemodynamic parameters.

Background: There is no unified prognostic scoring system for light chain cardiac amyloidosis (AL-CA), particularly stage IIIb AL-CA. This study aimed to use invasive haemodynamic information to investigate markers that can more accurately evaluate the prognosis of patients with stage IIIb AL-CA.
Methods: In this retrospective cohort study, we conducted invasive haemodynamic measurements concurrently with myocardial biopsies to diagnose AL-CA.

Objective: Tafamidis has shown potential in slowing disease progression in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). This study aimed to evaluate serial changes on [Tc]Tc-pyrophosphate (PYP) scintigraphy during tafamidis treatment for hereditary ATTR-CM.
Methods: We retrospectively analyzed a prospectively collected cohort of Ala97Ser (A97S) hereditary ATTR-CM patients treated with tafamidis (61 mg/day) and a control group comprising A97S hereditary ATTR-CM patients who had not received disease-modifying medications.

Background: Amyloidosis combined with lung cancer is a rare occurrence. To date, there are no reported cases of amyloid light-chain(AL) amyloidosis solely affecting the colon combined with pulmonary adenocarcinoma.
Case Summary: Here, we describe a case of a 66-year-old woman who presented with recurrent abdominal pain and was eventually diagnosed with AL amyloidosis with colon involvement and pulmonary adenocarcinoma.
A Case of Ossified Tissue Misdiagnosed as Amyloid Deposits by Congo Red Stain and Birefringence.
Cureus

Pathology, Tokyo Metropolitan Tama Medical Center, Fuchu, JPN.
Pulmonary amyloidosis is diagnosed by identifying amyloid deposits using Congo red stain (CR) and birefringence under polarized light. However, collagen fibers can also produce similar staining results, complicating diagnosis. We report a case of a 55-year-old male patient with lung opacities, initially suspected to have amyloidosis based on CR positivity and green birefringence.
