The lesions are generally solitary sessile papules or skin tag lesions that occur during childhood. We retrospectively reviewed patients diagnosed with RMH pathologically between January 2001 and June 2020 at a tertiary medical center. A literature review was conducted. Seven plaque-type RMHs on the chin were found, including 6 in adults and one in a 14-year-old boy. The average age was 45.7 years. The onset of the RMH appearance was between several months and years. Pathologically, all patients showed a scattered haphazard arrangement of skeletal muscle bundles in the dermis and\/or subcutis. Subcutis replaced by fibrous tissue and skeletal muscle bundles was present in 2 cases. Some skeletal muscles had a periadnexal distribution. This case series demonstrated a distinct clinical presentation of acquired RMH specifically located on the chin.<\/jats:p>","DOI":"10.1097\/dad.0000000000002016","type":"journal-article","created":{"date-parts":[[2021,7,7]],"date-time":"2021-07-07T07:22:37Z","timestamp":1625642557000},"page":"908-912","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Plaque\u2010Type
