Rhabdomyomatous mesenchymal hamartoma is a rare
lesion of the dermis and subdermal tissue. It was first
described in 1986 as “striated muscle hamartoma”. It
has been usually reported in newborns. Until recently,
there were only 34 reported cases in the literature.
We herein report a three-month-old boy with a congenital
skin tag in the middle of the chin. Physical examination
revealed no congenital abnormalities or other dermal
lesions. Histopathological examination showed a
mixed tissue collection of subepidermal disorganized
skeletal muscle fibers, adipose, fibrous and neural tissues,
and abundant folliculosebaceous structures.
Clinically, the differential diagnosis of rhabdomyomatous
mesenchymal hamartoma includes skin tag, accessory
tragus and soft fibroma. If the presence of striated
muscle fibers has been ignored, there is microscopic resemblance
between all of these lesions. Because of the
absence of recurrence or malignant degeneration, this
lesion may be accepted a negligible diagnosis. But for as
many as 30% of the reported cases with rhabdomyomatous
mesenchymal hamartoma have several congenital
anomalies; the differential diagnosis of this lesion is important.
