It manifests as discrete, rounded nodules within the lung parenchyma. A 39-year-old woman presented for investigation after pulmonary nodules were found incidentally. Chest computed tomography showed multiple, discrete, non-enhancing pulmonary nodules bilaterally. Positron emission tomography (PET) was negative. Biopsy demonstrated a non-specific lymphoplasmacytic infiltrate. Open resection yielded two nodules consistent with hyalinizing granulomas. The differential for multiple pulmonary nodules is broad. PET scan can help rule out metastatic disease, although some cancers are not hypermetabolic on PET. Furthermore, some non-malignant conditions, including hyalinizing granuloma, can show increased activity on PET. PHG should be included in the differential of multiple pulmonary nodules, especially if nodule stability can be demonstrated and\/or needle biopsies are non-diagnostic. Associated immune-mediated conditions, such as idiopathic thrombocytopenic purpura (ITP) in our patient, may also favor HG. In this case report we find an association between PHG and ITP.<\/jats:p>","DOI":"10.4103\/2156-7514.127835","type":"journal-article","created":{"date-parts":[[2014,2,25]],"date-time":"2014-02-25T07:19:28Z","timestamp":1393312768000},"page":"8","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Pulmonary Hyalinizing Granuloma Associated with Idiopathic Thrombocytopenic Purpura"],"prefix":"10.25259","volume":"4","author":[{"given":"Christopher","family":"Coleman","sequence":"first","affiliation":[{"name":"Department of Diagnostic Radiology, Mayo Clinic, Jacksonville, FL 32224, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aziza","family":"Nassar","sequence":"additional","affiliation":[{"name":"Department of Pathology, Mayo Clinic, Jacksonville, FL 32224, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Barbara","family":"McComb","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Mayo Clinic, Jacksonville, FL 32224, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2014,2,25]]},"reference":[{"key":"10.4103\/2156-7514.127835\/ref-1","first-page":"997","article-title":"Pulmonary hyalinizing granuloma","volume":"115","author":"Engleman","year":"1977","journal-title":"Am Rev Respir Dis"},{"key":"10.4103\/2156-7514.127835\/ref-2","doi-asserted-by":"crossref","DOI":"10.1155\/2010\/984765","article-title":"Hyalinizing granuloma: An unusual case of a pulmonary mass","author":"Brand\u00e3o","year":"2010","journal-title":"Case Rep Med 2010"},{"key":"10.4103\/2156-7514.127835\/ref-3","doi-asserted-by":"crossref","first-page":"662","DOI":"10.1590\/S1806-37132010000500019","article-title":"Recurrent pulmonary hyalinizing granuloma","volume":"36","author":"Arruda","year":"2010","journal-title":"J Bras Pneumol"},{"key":"10.4103\/2156-7514.127835\/ref-4","first-page":"1459","article-title":"Pulmonary hyalinizing granuloma.
