Papulosquamous disorders comprise a group of dermatoses that have distinct morphologic features. The characteristic primary lesion of these disorders is a papule, usually erythematous, that has a variable amount of scaling on the surface. Plaques or patches form through coalescence of the primary lesions. Some common papulosquamous dermatoses are pityriasis rosea, lichen planus, seborrheic dermatitis, tinea corporis, pityriasis rubra pilaris, psoriasis, and parapsoriasis. The etiology, diagnosis, and treatment of pityriasis rosea, lichen planus, and seborrheic dermatitis (including seborrheic dermatitis associated with AIDS) are discussed in this chapter. Also discussed are the diagnosis and treatment of pityriasis rubra, parapsoriasis (pityriasis lichenoides and small- and large-plaque parapsoriasis), and erythroderma. This chapter includes color photographs of the aforementioned dermatoses plus the Koebner phenomenon, lichen planus of the mucous membranes, and erythroderma in Sézary syndrome. This review contains 11 highly rendered figures and 79 references.

Pityriasis Rubra Pilaris

Imiquimod is an immunomodulator with both antitumor and antiviral properties. It is currently available in two cream formulations as Aldara (imiquimod 5%) and the newly approved Zyclara (imiquimod 3.75%). Imiquimod has been associated with localized erythema, crusting, and scaling at the site of application. However, more severe generalized skin eruptions including erythema multiforme, psoriasis, and hyperpigmentation have been described. The newly approved imiquimod 3.75% cream is a presumably safer alternative due to its lower concentration. This paper describes the development of generalized acantholytic pityriasis rubra pilaris after the treatment of an actinic keratosis on the forehead with imiquimod 3.75% cream.

There have been increasing reports of skin manifestations in COVID-19 patients. We conducted a systematic review and included manuscripts describing patients with positive RT-PCR coronavirus testing from nasopharyngeal swabs who also developed cutaneous manifestations. A total of 655 patients were selected, with different types of skin rashes: Erythematous maculopapular (n = 250), vascular (n = 146), vesicular (n = 99), urticarial (n = 98), erythema multiforme/generalized pustular figurate erythema/Stevens-Johnson syndrome (n = 22), ocular/periocular (n = 14), polymorphic pattern (n = 9), generalized pruritus (n = 8), Kawasaki disease (n = 5), atypical erythema nodosum (n = 3), and atypical Sweet syndrome (n = 1). Chilblain-like lesions were more frequent in the younger population and were linked to a milder disease course, while fixed livedo racemosa and retiform purpura appeared in older patients and seemed to predict a more severe prognosis. For vesicular rashes, PCR determined the presence of herpesviruses in the vesicle fluid, which raised the possibility of herpesvirus co-infections. The erythema-multiforme-like pattern, generalized pustular figurate erythema and Stevens-Johnson syndrome were most frequently linked to hydroxychloroquine intake. A positive PCR determination of SARS-COV-2 from conjunctival swabs suggest that eye discharge can also be contagious. These cutaneous manifestations may aid in identifying otherwise asymptomatic COVID-19 carriers in some cases or predict a more severe evolution in others.

To the Editor.— Erythema multiforme (EM) is an acute, self-limited mucocutaneous eruption characterized by the abrupt onset of symmetrical, fixed, red papules, some of which evolve into target lesions, the hallmark of EM.1 Since the original description by Ferdinand von Hebra in 1860, there has been confusion regarding the diagnosis.2 From children referred for a National Institutes of Health-sponsored research study of EM, we noted that a large majority of the children did not meet the criteria for EM.1
