Intramyofiber skeletal muscle invasion is the rarest pattern of muscle invasion, where the architecture of the individual myofibers remain preserved. This uncommon pattern of skeletal muscle invasion has occasionally been identified in Ewing sarcoma, non-Hodgkin lymphomas and leukemias however there are sparse literatures available on carcinomas showing intramyofiber pattern of invasion. They can closely mimic myositis and can be missed on low magnification. Thus, careful examination in high magnification supported by immunohistochemistry can resolve the issue. Here we present one case of intramyofiber skeletal muscle invasion in oral squamous cell carcinoma.<\/jats:p>","DOI":"10.4103\/ijpm.ijpm_880_22","type":"journal-article","created":{"date-parts":[[2025,8,18]],"date-time":"2025-08-18T16:01:03Z","timestamp":1755532863000},"page":"900-902","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Intramyofiber invasion in a case of oral squamous cell carcinoma; an unusual pattern of skeletal muscle infiltration"],"prefix":"10.4103","volume":"68","author":[{"given":"Soumya","family":"Dey","sequence":"first","affiliation":[{"name":"Department of Pathology, IPGME and R, Kolkata, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Md","family":"Mohin","sequence":"additional","affiliation":[{"name":"Department of Pathology, IPGME and R, Kolkata, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moumita","family":"Sengupta","sequence":"additional","affiliation":[{"name":"Department of Pathology, IPGME and R, Kolkata, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uttara","family":"Chatterjee","sequence":"additional","affiliation":[{"name":"Department of Pathology, IPGME and R, Kolkata, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,8,14]]},"reference":[{"key":"R1-20251208","doi-asserted-by":"crossref","first-page":"133","DOI":"10.5125\/jkaoms.2016.42.3.133","article-title":"Muscular invasion by oral squamous cell carcinoma of the posterior mandibular alveolar ridge is associated with cervical lymph node metastasis","volume":"42","author":"Min","year":"2016","journal-title":"J Korean Assoc Oral Maxillofac Surg"},{"key":"R2-20251208","doi-asserted-by":"crossref","first-page":"359","DOI":"10.1007\/s12105-011-0296-5","article-title":"Muscle invasion in oral tongue squamous cell carcinoma as a predictor of nodal status and local recurrence: Just as effective as depth of invasion?","volume":"5","author":"Chandler","year":"2011","journal-title":"Head Neck Pathol"},{"key":"R3-20251208","doi-asserted-by":"crossref","first-page":"103","DOI":"10.1002\/jso.2930300208","article-title":"Intramyofiber metastasis in skeletal muscle","volume":"30","author":"Sarma","year":"1985","journal-title":"J Surg Oncol"},{"key":"R4-20251208","doi-asserted-by":"crossref","first-page":"478","DOI":"10.4103\/IJPM.IJPM_1371_20","article-title":"Intramyofiber skeletal muscle invasion: An unusual pattern of muscle infiltration in breast cancer","volume":"65","author":"Dey","year":"2022","journal-title":"Indian J Pathol Microbiol"},{"key":"R5-20251208","doi-asserted-by":"crossref","first-page":"36","DOI":"10.1016\/j.semcdb.2018.07.014","article-title":"Cancer invasion into musculature: Mechanics, molecules and implications","volume":"93","author":"Beunk","year":"2019","journal-title":"Semin Cell Dev Biol"},{"key":"R6-20251208","doi-asserted-by":"crossref","first-page":"1045","DOI":"10.1016\/S0046-8177(82)80098-1","article-title":"Intraskeletal myofiber metastasis of breast carcinoma","volume":"13","author":"Lasser","year":"1982","journal-title":"Hum Pathol"}],"container-title":["Indian Journal of Pathology and Microbiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/ijpm.ijpm_880_22","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T13:20:24Z","timestamp":1787836824000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/ijpm.ijpm_880_22"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,14]]},"references-count":6,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.4103\/ijpm.ijpm_880_22","relation":{},"ISSN":["0377-4929","0974-5130"],"issn-type":[{"value":"0377-4929","type":"print"},{"value":"0974-5130","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8,14]]},"assertion":[{"value":"2022-11-06","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-05-29","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
