Targetoid hemosiderotic hemangioma
Uncommon, benign, solitary, vascular lesion of lymphatic origin. The classic clinical presentation is as single, annular, targetoid-appearance vascular lesion with a brown to violaceous central papule surrounded by a thin, pale area and a peripheral ecchymotic ring. Patients usually describe cyclic changes in their lesions. Dermoscopy:
- Central area with red and dark lacunae
- Peripheral circular reddish-violaceous homogeneous area
- Sometimes, intermediate skin-coloured, yellow or white circular homogeneous area.
- Occasionally, a reddish-violaceous or ecchymotic homogeneous area occupies the whole lesion.
- A peripheral delicate pigment network, white structures (shiny white lines) may be present.
