Objective: To analyze the clinical characteristics and pathological features of patitents with angiokeratoma. Methods: During the period from 2008 to 2018, 18 cases with adult angiokeratoma were collected and analyzed using HE staining. Results: 18 cases with angiokeratoma, male 10 cases, female 8 cases, and the ratio of male to female was 1.25:1. The age of presentation was from 13 to 79 years old, and the mean age was 45.9 years old. The course of disease lasted from 1 month to 2 years, average 6.6 months. Clinically, the Mibelli type of angiokeratoma and Scrotal angiokeratioma are most common. Pathological examination of skin lesions revealed that angiokeratoma characteristically has large dilated capillaries in the papillary dermis with thickening of the stratum spinosum and hyperkeratosis, and the dilated capillaries are surround by the overlying epithelium. The treatments of angiokeratoma includes: direct surgical excision, and laser. Conclusion: The clinical manifestation of angiokeratoma is diverse. Analyzing its clinical characteristics and pathological features can help the clinician and pathologist to further understand angiokeratoma and improve the diagnostic accuracy.
