Abstract
Background: Amyloidosis is the extracellular accumulation of amyloid proteins in diverse organs. While ocular and periocular involvement is rare, it can be localised or part of systemic disease. This manifestation can affect various ocular structures, including the eyelids, conjunctiva, lacrimal glands, cornea, vitreous body, extraocular muscles and ocular adnexa, leading to symptoms like ptosis. Here, we report a unique case of systemic amyloidosis presenting as papulonodules on the eyelids, diagnosed through a minimally invasive fine needle aspiration technique (FNAC).
Case presentation: A 43-year-old male presented with red to skin-coloured elevated lesions, primarily around the periocular region, persisting for 2 months. Examination revealed multiple waxy papulonodules predominantly on the eyelids, with some also in the perioral area, forehead, and neck. Additionally, the patient exhibited macroglossia with ulcers. While urine Bence Jones protein tests were negative, the urine protein creatinine ratio was elevated. Echocardiography indicated concentric left ventricular hypertrophy (LVH). FNAC from periocular papulonodules and abdominal fat pad yielded fluidy and greasy white material, respectively. The smears from eyelid lesions showed pale eosinophilic, acellular, waxy material, which was congophilic, and apple-green birefringence in polarised light. The abdominal fat pad FNAC also was positive for amyloidosis. The subsequent skin biopsies from the patient's forehead, papules, and tongue revealed eosinophilic, amorphous extracellular material deposition. Congo red staining effectively highlighted the congophilic material. These biopsy findings aligned with the earlier FNAC results, confirming the diagnosis of amyloidosis in both.
Conclusion: This case highlights the unusual presentation of systemic amyloidosis as eyelid papules and nodules, underscoring the importance of FNAC in such scenarios. FNAC is a rapid and effective diagnostic tool for accessible lesions, as demonstrated in this case. Additionally, FNAC of abdominal fat pads can provide valuable diagnostic information swiftly, making it useful in suspected amyloidosis cases.
期刊介绍:
The aim of Cytopathology is to publish articles relating to those aspects of cytology which will increase our knowledge and understanding of the aetiology, diagnosis and management of human disease. It contains original articles and critical reviews on all aspects of clinical cytology in its broadest sense, including: gynaecological and non-gynaecological cytology; fine needle aspiration and screening strategy.
Cytopathology welcomes papers and articles on: ultrastructural, histochemical and immunocytochemical studies of the cell; quantitative cytology and DNA hybridization as applied to cytological material.
