Areata-Like Lupus as a Clinical Manifestation of Cutaneous Lupus Erythematosus.

Introduction: Lupus erythematosus (LE) is a chronic autoimmune disease that frequently causes hair loss and scalp lesions. Hair loss can be scarring and nonscarring, diffuse, or patchy. The nonscarring patchy alopecia is usually related to systemic LE (SLE) and may simulate alopecia areata (AA), reason why it is named areata-like lupus.

The impact of an educational video about radiotherapy and its toxicities in head and neck cancer patients. Evaluation of patients' understanding, anxiety, depression, and quality of life.

Objectives: Head and neck radiotherapy can cause several toxicities, and its management has important treatment implications. Proper information about treatment is crucial to assist patients by preparing them and enhancing their ability to manage their illness. Thus, this study aimed to verify the impact of an educational video on the improvement of the patient's understanding, satisfaction, quality of life, and influence on their emotional state in different moments of treatment.

Diagnostic approach of eosinophilic spongiosis.

Eosinophilic spongiosis is a histological feature shared by some distinct inflammatory disorders, and is characterized by the presence of intraepidermal eosinophils associated with spongiosis. Most often, isolated eosinophilic spongiosis indicates the early stages of a subjacent autoimmune bullous dermatosis, such as the pemphigus group and bullous pemphigoid. Herein, the main causes of eosinophilic spongiosis are discussed, as well as the supplementary investigation needed to elucidate its etiology.

Lichen Planopilaris with Pustules: A Diagnostic Challenge.

Introduction: Lichen planopilaris (LPP) is a lymphocytic primary cicatricial alopecia presenting with scarring hair loss and variable degrees of perifollicular erythema and scaling. Pustules are infrequent and may mimic folliculitis decalvans (FD) and other forms of neutrophilic alopecia. We present a series of LPP cases with pustules and discuss the importance of differentiating them from primary neutrophilic folliculitis.

Histopathological and clinical evaluation of chronic spontaneous urticaria patients with neutrophilic and non-neutrophilic cutaneous infiltrate.

Background: Chronic urticaria has an expressive prevalence in general population, especially in adults, and is defined by the presence of intermittent hives for six weeks or longer. Our study aims to characterize the histological patterns of chronic spontaneous urticaria, based on the inflammatory cell infiltrate, and correlate them to laboratory exams.

Methods: It was performed a retrospective analysis of laboratory, histopathology and direct immunofluorescence data of 93 patients with chronic urticaria.
