“…The authors suggest to make a diagnosis of "hamartoma of cutaneous adnexa and mesenchyme" proposed by Grilli et al to replace RMH. 15,16 However, the proposed term is not specific enough and may be confused with other hamartomas, such as folliculosebacous cystic hamartoma. 16 Therefore, RMH is still used to reflect a hamartomatous proliferation of skeletal muscles in the skin.…”

The plaque located on the chin may reflect an etiology of aberrant embryologic development of the platysma muscle because it was inserted superficially into the dermis over the mandible.…”

Rhabdomyomatous mesenchymal hamartoma (RMH) is a rare benign tumor composed of skeletal muscle fibers and other mesenchymal-derived cells. 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-yearold 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.

Rhabdomyomatous mesenchymal hamartoma (RMH) is a rare congenital lesion of the dermis and subdermis. It has been described predominantly in newborns, with 30 cases reported in the English literature. Typically, it appears as a skin tag, papule, nodule or a mass involving the face or sternal notch. A 28-day-old girl presented with a 1.4 x 0.8 cm soft skin tag in the right sternoclavicular area. Physical examination revealed no congenital anomalies. A shaved biopsy showed that the core of the lesion contained striated muscle fibers mixed with hair follicles and sebaceous and eccrine glands. Thin epidermis lined the outside of the tag. We report a patient with a RMH in a site not previously reported and discuss the differential diagnosis.
