Although diagnosis of cutaneous granulomatous disorders (CGDs) is usually suspected based on morphologic findings, localization, and anamnestic data, clinical differentiation from each other and from similar dermatoses may be challenging. Recently, dermatoscopy has been demonstrated to be a useful tool for assisting the recognition of several CGDs. This article provides a current overview of the dermatoscopic features of the main noninfectious and infectious CGDs, including sarcoidosis, necrobiosis lipoidica, granuloma annulare, rheumatoid nodules, and leishmaniasis. Other, less common, CGDs are briefly addressed, including granulomatous rosacea, acne agminata, and leprosy.
