Cutaneous manifestations during Coronavirus Disease 2019 (COVID‐19) include pityriasis rosea (PR) and PR‐like eruptions 1‐3 . We describe a patient with PR demonstrating that concurrent viral reactivations may occur during COVID‐19. This article is protected by copyright. All rights reserved.

To explain why in alopecia areata the hair falls out in a particular area the hypothesis is proposed that the area occurs as a stochastic event only in those subjects who, in a restricted zone of their scalp, happen to have a group of hairs that are simultaneously in the early anagen VI subphase of the hair cycle. Once this point has been accepted, a number of conclusions may be drawn. Especially important is the inference that only people with low percentages of telogen hairs are likely to exhibit areas, whereas those with androgenetic alopecia, when affected by alopecia areata, preferentially show a diffuse and delayed hair loss that has the features of Kligman’s telogen effluvium (alopecia areata incognita). Epidemiological evidence is provided.

We describe 3 cases of papular and nodular mucinosis (PNM), a clinically distinctive cutaneous mucinosis associated with lupus erythematosus (LE), which has received little attention in the dermatologic literature. Histopathology shows deposits of mucin in the dermis without microscopic features of LE while immunofluorescent studies disclose linear or granular deposits of IgG, IgM and C3 at the dermoepidermal junction. In about 80% of the 14 cases described in the literature PMN has been associated with systemic LE with prevalent joint and kidney involvement. The possible prognostic significance of this singular dermatosis is discussed.
