Abstract
Abstract: The fibroadipose vascular anomaly (FAVA) is a relatively unknown vascular anomaly in the realm of adult dermatopathology. Despite its intramuscular location, dermatologists often encounter cases, approaching them surgically under the presumption of a potential lipoma. This entity was first described in 2014, and consequently, many FAVA cases may be concealed in our archives under diagnoses of other entities that require differential diagnoses, such as intramuscular fast-flow vascular anomaly. Clinically, these anomalies typically manifest preferably in young women or girls and predominantly in the extremities. In this article, we present 2 cases of FAVA with atypical clinical features in terms of their topography and age at onset. However, histopathologically, they exhibit typical characteristics with fibroadipose tissue and dysmorphic venous vessels dissecting the affected striated muscle.
