You need to be seen by your dermatologist in person.

Suzanne Sirota Rozenberg, DO, FAOCD, FAAD

There are a number of skin conditions that can present in a manner such as yours including progressive pigmentary purpura, lichen amyloidosis, contact dermatitis and psoriasis. Based on your clinical presentation and severity of itch, a confirmatory biopsy is indicated to establish a diagnosis and guide treatment selection. Dermatologists are specifically trained to diagnosis and treat your condition once established through a biopsy. Best regards,
