Fig 1
Multicolored rainbow pattern in an aneurysmal dermatofibroma observed on dermatoscopy.
Fig 2
Fig 2
Histopathology of aneurysmal dermatofibroma. There are fibroblast proliferation within the dermis with peripheral collagen trapping, focal interstitial hemorrhage, and an overlying acanthotic epidermis with tabled hyperpigmented rete ridges.
Fig 3
Fig 3
Dermatoscopic rainbow pattern observed at the periphery with central ulceration in a pleomorphic sarcoma.
Fig 4
Fig 4
Histopathology of pleomorphic sarcoma. A to C, A tumor composed of atypical epithelioid cells and numerous mitoses closely abutted on the epidermis. D, CD10 immunostaining to evaluate for pleomorphic sarcoma was strongly and diffusely positive. E, Pan-cytokeratin immunostaining to evaluate for squamous cell carcinoma was negative. F, SOX10 immunostaining to evaluate for melanoma was negative.

Fig 5
Intravascular papillary endothelial hyperplasia (Masson tumor) with dermatoscopic rainbow pattern in the central area.
Fig 6
Fig 6
Histopathology of intravascular papillary endothelial hyperplasia (Masson tumor). Within the dermis is a sharply circumscribed nodule with an intraluminal proliferation of plump endothelial cells with papillary formations and thrombi.
