Discussion. The following differential diagnosis may be considered: A. Pityriasis rosea B. Psoriasis C. Pityriasis lichenoides Chronica D. Small plaque parapsoriasis E. All of the above . Pityriasis lichenoides is a rare skin disorder of unknown cause. Successive crops appear over weeks, so all stages of lesions can be present at one time. This observation is useful in trying to answer the PLC patients question about what causes this? It proliferates in "Dandruff ' and 'Seborrhoeic Dermatitis' and in the diseases/ conditions discussed herein - prefixed Pityriasis. It typically presents abruptly and dramatically with a wide-spread eruption of red to black ulcerated, necrotic plaques. There are several theories about the cause of the disease, including that it may be a response by the immune system to an infection or medication. Unlike lighter skinned patients where lesions leave without any trace, a patient with skin of color is often left with persistent reminders of previous outbreaks.
