The clinical differential diagnosis for a scalp lesion that appears similar to a cherry angioma includes angiokeratoma, venous lake, pyogenic granuloma, and metastatic carcinoma. Therefore, dermatologists should be aware that cherry angiomas can present as multiple macules or papules on the scalp. Understandably, many people are not aware of cherry angiomas on the scalp, as they are usually asymptomatic and concealed under hair. There is a possibility that the actual incidence of cherry angiomas on the scalp may be much higher than what is currently reported. In Pereira's report, about 72% of patients had cherry angiomas on the scalp. On the other hand, Pereira reported that a high frequency of cherry angiomas occurred on the scalp. For example, Keller reported that of hundreds of cases of cherry angiomas, only 2 cases were located on the scalp. In fact, cherry angiomas on the scalp are rarely reported.

However, they are rarely seen on other body parts such as face, hands and feet. Cherry angiomas most commonly occur on the trunk or proximal extremities. The lesions are usually asymptomatic, but may bleed with trauma. As the lesions develop, they become 1- to 5-mm red papules. It is assumed that his lesions developed incidentally or as a result of an aging process.Ĭlinically, early lesions appear as flat, red macules that look like petechiae. In this case, the patient had no history of medical illness or exposure to chemicals. Furthermore, cherry angiomas have been associated with liver transplants, graft-versus-host disease, and patients who are immunocompromised secondary to cyclosporine treatment. Cherry angiomas are also known to be related to chemical exposures. One study has reported that cherry angiomas tend to be larger in diabetic patients, and another study reported that cherry angiomas have an increased expansion rate in tropical climates. However, several factors are considered as inducing factors. The etiology of cherry angiomas remains unknown. Generally, cherry angiomas develop after the third decade, and the number of lesions increases with age. The actual prevalence of cherry angiomas is not well-known, but one study reported that cherry angiomas were observed in 5% of adolescents and 75% of adults over 75 years of age.

Cherry angiomas are the most common form of acquired vascular proliferation of the skin and were first described in 1872 by Campbell de Morgan.
