Later, he developed haemoptysis for which he presented to our tertiary care subspecialty unit. Further evaluation with imaging revealed a left lung mass with adrenal and gastric lesions, raising suspicion of a lung malignancy with metastasis. A biopsy from a chest wall swelling confirmed primary lung small cell carcinoma with positive synaptophysin expression. Despite timely whole-brain radiotherapy and chemotherapy, his condition deteriorated rapidly, and he succumbed within weeks. This case highlights the rare presentation of small-cell lung carcinoma with cutaneous metastases, which is associated with poor prognosis.<\/jats:p>","DOI":"10.1136\/bcr-2026-272000","type":"journal-article","created":{"date-parts":[[2026,4,3]],"date-time":"2026-04-03T15:10:17Z","timestamp":1775229017000},"page":"e272000","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Atypical skin involvement as a harbinger of small-cell lung cancer"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-5990-290X","authenticated-orcid":false,"given":"Anjana","family":"Anilkumar","sequence":"first","affiliation":[{"name":"Pulmonary Medicine, All India Institute of Medical Sciences Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9520-6697","authenticated-orcid":false,"given":"Ritwick","family":"Singla","sequence":"additional","affiliation":[{"name":"Pulmonary Medicine, All India Institute of Medical Sciences Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lokesh Kumar","family":"Saini","sequence":"additional","affiliation":[{"name":"Pulmonary Medicine, All India Institute of Medical Sciences Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5136-7254","authenticated-orcid":false,"given":"Ravi Hari","family":"Phulware","sequence":"additional","affiliation":[{"name":"Pathology, All India Institute of Medical Sciences Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gayathri","family":"Saravanan","sequence":"additional","affiliation":[{"name":"Pathology, All India Institute of Medical Sciences Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,4,3]]},"reference":[{"key":"2026062608153016000_19.4.e272000.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mayocp.2019.01.034"},{"key":"2026062608153016000_19.4.e272000.2","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2013-009160","article-title":"Multiple cutaneous nodules as the presenting sign of small cell lung cancer","volume":"2013","author":"Brinkman","year":"2013","journal-title":"BMJ Case Rep"},{"key":"2026062608153016000_19.4.e272000.3","doi-asserted-by":"crossref","first-page":"571","DOI":"10.1016\/j.abd.2022.10.009","article-title":"Cutaneous metastases from solid neoplasms -
