ABSTRACT

Introduction: Tracheobronchial amyloidosis is an uncommon localized form of amyloidosis that can simulate a tracheal tumor. Clinical signs are not specific and the diagnosis is rarely given before performing a bronchoscopy with multiples biopsies.

Case presentation: We report the case of a 60-year-old Moroccan woman, complaining of dyspnea and wheezing for three years, who was treated at our institution for management of severe asthma. A bronchoscopy revealed a tumor formation of her trachea; multiples biopsies were performed and a diagnosis made of amyloid light-chain amyloidosis. She successfully received an endoscopic resection.

Conclusion: This case highlights the importance of routinely carrying out an endoscopy in any patient complaining of atypical bronchial symptoms or with uncontrolled asthma. Tracheal amyloidosis is a rare disease, confirmed by histological examination of bronchial biopsies, and the treatment of choice is based on the bronchoscopic resection.

Tracheal biopsy and histology findings. (a) A tracheal biopsy revealed a chorion occupied by massive amyloid deposits. (b) Intense staining by anti-lambda light chain antibodies confirming the diagnosis of an amyloid light-chain amyloid tumor.

Figure 3: Tracheal biopsy and histology findings. (a) A tracheal biopsy revealed a chorion occupied by massive amyloid deposits. (b) Intense staining by anti-lambda light chain antibodies confirming the diagnosis of an amyloid light-chain amyloid tumor.

Mentions: The tracheal biopsies revealed a chorion occupied by massive amyloid deposits (Figure 3a). These deposits showed a green birefringence under crossed polarized light after Congo red staining. An immunohistochemical analysis showed intense staining by anti-lambda light chain antibodies confirming the diagnosis of an amyloid light-chain (AL) amyloid tumor (Figure 3b).
