Although the lesions appeared malignant on imaging, they were benign by biopsy. The enlarging left anterior chest wall mass was surgically resected to prevent cardiovascular compression. The significant chest wall defect was reconstructed using the bird-cage technique with overlying pectoralis major muscle flap and native skin. The lesions at the left posterior rib and left maxillary sinus were closely observed. This case is the first reported synchronous chest wall and maxillary sinus chondromesenchymal hamartoma.<\/jats:p>","DOI":"10.1136\/bcr-2022-252019","type":"journal-article","created":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T03:26:07Z","timestamp":1698204367000},"page":"e252019","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Chest wall and nasal chondromesenchymal hamartoma in a toddler: treated during a global pandemic"],"prefix":"10.1136","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6949-4924","authenticated-orcid":false,"given":"Joan Kristi Decena","family":"Zaldivar","sequence":"first","affiliation":[{"name":"Department of Surgery, University of the Philippines-Philippine General Hospital, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eduardo","family":"Bautista","sequence":"additional","affiliation":[{"name":"Department of Surgery, University of the Philippines-Philippine General Hospital, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jesyl Obtinario","family":"Gagto","sequence":"additional","affiliation":[{"name":"Department of Surgery, Philippine General Hospital, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,10,24]]},"reference":[{"key":"2025082708095628000_16.10.e252019.1","doi-asserted-by":"crossref","first-page":"e37","DOI":"10.1016\/j.jpedsurg.2010.08.057","article-title":"Perinatal evolution of mesenchymal hamartoma of the chest wall","volume":"45","author":"Braatz","year":"2010","journal-title":"J Pediatr Surg"},{"key":"2025082708095628000_16.10.e252019.2","doi-asserted-by":"crossref","unstructured":"Golbin DA , Ektova AP , Demin MO , et al .
