Erythema on shoulder may be caused by hemangioma, spider nevus, allergic purpura, etc. It is necessary to clarify the cause of the disease and then treat the symptomatic condition. Common treatments include medication (e.g. anti-histamine drugs), physical therapy (electrocautery, laser, etc.), and surgical excision treatment.
1. Hemangioma: it may be related to the abnormal proliferation of blood vessels during the embryonic development period, and is divided into benign tumor, junctional tumor and malignant tumor, which manifests itself in skin color, morphological changes and skin elevation. Treatment is related to the specific type of hemangioma. Commonly used treatments include medication (propranolol, prednisone, etc.), surgery, and laser treatment.
2. Spider nevus: a kind of red vascular lesion, commonly seen in face, neck, arm, shoulder and other parts of the body, manifesting itself as a central protrusion, with a lot of spider leg-like capillaries sticking out in all directions. It can be removed by high-frequency electrocautery, laser and other physical ways, and can be removed by surgery if necessary.
3. Anaphylactic purpura: due to the allergic reaction to certain sensitizing substances, manifested by the appearance of varying sizes of purpura slightly above the skin, but also arthralgia, abdominal pain, blood in the stool and other symptoms. It is necessary to stop contacting any substances that may cause allergy and to use drugs such as loratadine for treatment.
Erythema on the shoulders may also be caused by other factors (such as nevus erythematosus, etc.), it is recommended to consult a doctor in time in order to clarify the cause of the symptomatic treatment, and to avoid using medication privately, so as not to delay the condition.
