Ecchymosis ring

Introduction The ecchymotic ring is one of the typical symptoms of a target hemosiderin-bearing hemangioma. The disease is a subtype of a single hemangioma. Tumors that occur from vascular tissue are called hemangiomas, of which 80% are congenital. Hemangiomas are benign, slow-growing, and rarely malignant. The cause of the ecchymosis ring may be the original hemangioma with thrombus, which is caused by revascularization after trauma. In 1999, Carlson et al studied 33 cases of this disease, which is considered to be a subtype of single hemangioma.

Examination and diagnosis of ecchymosis ring:

The typical lesions are single-shot, ring-shaped lavender to purple papules with a diameter of 2 to 3 mm, surrounded by grayish edges, and the outer periphery of the gray-white margin is a ecchymotic ring, giving the lesion a target-like appearance. This loop expands to the periphery and eventually fades. Late lesions were only slightly purplish purple purplish. Most of the skin lesions occur in the trunk and limbs of young and middle-aged men.

According to the clinical manifestations, combined with histopathological examination, immunohistochemical staining can be diagnosed.

Differential diagnosis

Freckled ring confusing symptoms:

Hemangioma: A congenital benign tumor composed of vascular tissue, a common disease of dysplasia. It can occur in any part of the body. The skin and oral mucosa are the most common. The face, neck and limbs are good sites. In addition, it can occur in muscles, bones and internal organs.

Vascular malformations: all exist at birth, depending on the type of lumen, it becomes obvious at different times. Capillary malformation is more obvious at birth, lymphatic malformation is more obvious than 1 year old, and dynamic (static) vein deformity is more in infancy. Not obvious, but often manifested after changes in hormone levels, trauma, and infection.
