Parapsoriasis refers to one of a group of skin disorders that are characterized primarily by their resemblance to psoriasis (red, scaly lesions), rather than by their underlying cause. Neoplasms can develop from parapsoriasis. For example, it can develop into cutaneous T-cell lymphoma. The word "parapsoriasis" was formed in 1902. Classification
The parapsoriasis groups, described and debated for nearly a century, has spawned a confusing nomenclature. There are some authors who prefer to limit the term "parapsoriasis" to large- and small-plaque variants only. However, the following classification scheme is now generally accepted:: 450 
Large-plaque parapsoriasis
Small-plaque parapsoriasis
Pityriasis lichenoides
Pityriasis lichenoides chronica
Pityriasis lichenoides et varioliformis acuta
Lymphomatoid papulosis

This is where the sulfamethoxazole comes in; its role is in depleting the excess DHF by preventing it from being synthesised in the first place.Co-trimoxazole was claimed to be more effective than either of its components individually in treating bacterial infections, although this was later disputed. Because it has a higher incidence of adverse effects, including allergic responses, its use has been restricted in many countries to very specific circumstances where its improved efficacy has been demonstrated. It may be effective in a variety of upper and lower respiratory tract infections, kidney and urinary tract infections, gastrointestinal tract infections, skin and wound infections, sepsis, and other infections caused by sensitive organisms. Co-trimoxazole decreases the risk of recurrence of retinochoroiditis. The global problem of advancing antimicrobial resistance has led to a renewed interest in the use of co-trimoxazole more recently. Society and culture
