Introduction
Smooth muscle hamartoma (SMH) is a benign skin tumor characterized by
the proliferation of smooth muscle bundles, primarily originating from
the pilomotor muscles. SMH most commonly presents in the lumbar and
sacral regions and typically manifests within the first six months of
life. The clinical presentation of SMH is characterized by pale brown
macules with slightly indistinct borders. To date, there have been few
reported cases of multiple SMH in the literature 1.
Additionally, there are very limited reports of acquired SMH2. In this report, we present a unique case of
acquired SMH with multiple distribution and depressed appearance.
