Blastic Plasmacytoid Dendritic Cell Neoplasm Associated with Dystrophic Xanthomatosis after Chemotherapy

Dystrophic xanthomization secondary to lichen planus pigmentosus associated with frontal fibrosing alopecia

“…Dystrophic xanthomas are defined by the accumulation of lipidrich foam cells within an area of damaged skin, independently of the normolipemic or hyperlipoproteinemic states. This uncommon phenomenon has been reported in local inflammatory (recurrent phlebitis and lymphangitis, photosensitivity disorders, erythroderma, herpes zoster), non-inflammatory (trauma, lymphoedema), and neoplastic diseases (breast carcinoma, hemathological disorders) 4. Dystrophic xanthomas have also been reported in cutaneous, oral, and genital lichen planus but not related to lichen planopilaris or LPPigm [5][6][7].…”
