Purple spots suddenly appearing on the neck may be purpura?

Purple spots appearing on the neck may indicate purpura, but could also be due to allergies, trauma, or other causes. Purpura is a disease characterized by subcutaneous bleeding, commonly seen in children and adolescents, and mainly manifests as skin petechiae and ecchymoses that do not fade upon pressure.

If the purple spots persist or increase in number, prompt medical attention is recommended for tests such as complete blood count and coagulation function. If diagnosed with purpura, further investigation is needed to identify underlying causes, such as whether there is thrombocytopenia or abnormal coagulation function.

Treatment varies depending on the cause and may involve medication, such as glucocorticoids or immunosuppressants. At the same time, adequate rest is important, with avoidance of strenuous exercise, and a light diet is recommended, avoiding seafood, spicy foods, and other allergenic substances.
