Smooth muscle hamartoma is an uncommon lesion. Diagnosis is usually made at birth in infants presenting a plaque with minimal or no infiltration and covered with long dark hairs. Congenital forms with multiple plaques are rarely reported.
A 5-day-old infant (normal pregnancy and delivery) had plaques localized on the buttocks, the left thigh, leg and shoulder and the right ankle. The plaques were minimally infiltrative and covered with long black hairs. Histology examination showed hyperplastic smooth muscle bundles with varying orientation. The diagnosis was smooth muscle hamartoma. The rest of the clinical examination was normal.
This case of congenital smooth muscle hamartoma showed a particular form with partially regressive multiple plaques.
平滑肌瘤是一种罕见的病变。诊断通常在出生时做出，表现为斑块，浸润极少或无浸润，表面覆盖着长长的深色毛发。先天性多发斑块的病例很少见。
一名5天大的婴儿（妊娠和分娩正常）臀部、左大腿、小腿、肩部及右踝部有斑块。这些斑块浸润极少，表面覆盖着黑色长毛。组织学检查显示平滑肌束增生，方向各异。诊断为平滑肌瘤。其余临床检查正常。
该例先天性平滑肌瘤表现为一种特殊形式，即多发斑块部分消退。
