Solitary pulmonary hyalinising granuloma : a rare cause of pulmonary nodule

Abstract

A pulmonary nodule is a common incidental finding on chest imaging, which includes a wide variety of differential diagnosis. Pulmonary hyalinising granuloma is a rare disease aetiology of pulmonary nodule(s). We report a 74-year-old female who was referred to the respiratory clinic with incidental finding of a solitary pulmonary nodule on chest X-ray. CT confirmed the presence of a 1.2 cm solitary pulmonary nodule in the left upper lobe with no lymphadenopathy. The patient underwent wedge resection, and histopathological examination of the lesion confirmed pulmonary hyalinising granuloma. In most previously reported cases, patients had multiple lesions on chest radiography. Solitary pulmonary lesion is an uncommon presentation of this clinical entity and only a few cases have been reported in the literature.
