RESUMO
Acroangiodermatitis is a rare, self-limiting, angioproliferative disorder associated with congenital vascular malformations or acquired venous insufficiency. The clinical features of acroangiodermatitis are notably similar to those of Kaposi sarcoma, making it difficult to differentiate between the two diseases. A 57-year-old male patient presented with multiple violaceous to black, crusted, indurated plaques with ill-defined margins on both swollen lower legs. A venous Doppler study of the bilateral lower limbs was unremarkable. A histopathological examination showed a hyperplastic epidermis, a prominent proliferation of small dilated vessels lined by plump endothelial cells in the dermis, hemosiderin deposits, and lymphocytic infiltrate around vessels. Immunohistochemical analysis showed CD31＋ and podoplanin＋ staining in endothelial cells.

RESUMO
BACKGROUND: Recently, the number of patients with scalp or hair loss disorder has rapidly been increasing and patient concerns are growing accordingly. With the flood of inadequate information available, many patients depend on treatments of which efficacy has not been proven. OBJECTIVE: To collect data on the awareness, knowledge, and behavior of scalp and hair loss disorders in Korean adults. METHODS: Between June 2015 and May 2016, a total of 1000 dermatologic outpatients, who visited St. Paul's Hospital and the Kyung Hee University Hospital at Gangdong were asked to complete a questionnaire. RESULTS: Fifty-three percent of survey responders reported scalp-related symptoms and 44% of all responders indicated that they had alopecia. Most responders (90%) agreed that scalp and hair loss disorders should be treated, and more than 80% thought they should be treated by a dermatologist; although, they hesitated to visit dermatology clinics because of skepticism of treatment effectiveness or economic burden. It was observed that the patients rely heavily on scalp-related products such as shampoo, conditioners, and hair tonic, trusting their effects, which have not been verified to be effective. CONCLUSION: Although patients who have hair loss or scalp diseases need to be treated appropriately by confirmed diagnosis of dermatologists, they often depend on non-professional methods rather than visiting dermatologists. Therefore, dermatologists should concentrate their efforts on correcting the misunderstandings about scalp and hair loss disorders to reduce unnecessary social economic burden.
