    Abstract Objective and design: The hallmark of type 2 inflammation is eosinophilia and/or high IgE serum levels, mostly in atopic dermatitis. Nevertheless, many dermatoses may present similar findings. Our aim is to explore the biological and clinical spectrum of cutaneous manifestations involving tissue and/or systemic eosinophilia, and distinct serum levels of IgE, where atopic dermatitis or other primary allergic eczema, not always is the definitive diagnosis.
    Materials/methods: A total of 37 scientific papers were enrolled in this narrative review.
    Results: A diagnostic approach for patients with elevated serum IgE level and a list of conditions not related to atopic dermatitis that runs through inborn errors of immunity, inflammatory disorders, lung disorders, malignancy, infections/infestations are displayed. Regarding to peripheral eosinophilia, differential diagnosis is also explored and clinical patterns of skin diseases associated with tissue eosinophilia are listed, to facilitate our diagnosis.
    Conclusions: We should maintain a high level of suspicion about other differential diagnosis involving eosinophilia and IgE dysregulation, especially in patients very young (when innate errors of the immunity may present) and in middle to elderly patients classified as having atopic dermatitis, due to the possibility of cutaneous hematological malignancies, paraneoplasia or autoimmune blistering diseases.

    Abstract Prurigo is a reactive, hyperplastic skin condition characterized by pruritic papules, plaques, and/or nodules. The temporal classification includes acute/subacute and chronic disease (≥ 6 weeks), with different clinical variants, synonymies, and underlying etiological factors. The immunology of chronic prurigo shows similarities with atopic dermatitis due to the involvement of IL-4 and IL-13, IL-22, and IL-31. Treatment includes antihistamines, topical steroids, dupilumab, and JAK inhibitors. Several conditions manifest clinically as prurigo-like lesions, and the correct clinical diagnosis must precede correct treatment. Furthermore, chronic prurigos represent a recalcitrant and distressing dermatosis, and at least 50% of these patients have atopic diathesis, the treatment of which may induce adverse effects, especially in the elderly. The quality of life is significantly compromised, and topical treatments are often unable to control symptoms and skin lesions. Systemic immunosuppressants, immunobiologicals, and JAK inhibitors, despite the cost and potential adverse effects, may be necessary to achieve clinical improvement and quality of life. This manuscript reviews the main types of prurigo, associated diseases, their immunological bases, diagnosis, and treatment.

    Abstract Chronic urticaria is a common condition presenting with intensely pruritic wheals. Although individual lesions resolve within 24 hours, by definition, chronic urticaria lasts for a duration of at least 6 weeks. Both spontaneous and inducible forms exist. In the spontaneous variant, chronic urticaria occurs in the absence of clearly identifiable triggers. In chronic inducible urticaria, specific triggers may include dermatographism, cholinergic (heat), cold, exercise, delayed pressure, and solar. Extensive laboratory evaluation for chronic spontaneous urticaria is not required unless indicated by clinical history or physical examination. Angioedema describes sudden onset of localized edema involving the deep layers of the skin and submucosal tissues. It can be seen in isolation or in conjunction with chronic urticaria. Angioedema typically resolves slower than wheals, taking up to 72 hours or longer. Histamine- and bradykinin-mediated forms exist. Both chronic urticaria and angioedema have many mimics, and a broad range of differential diagnoses should be considered. Importantly, an incorrect diagnosis may have significant implications for the additional investigation, treatment, and prognosis of the affected patient. The aim of this article is to discuss the characteristics of chronic urticaria and angioedema, and an approach to the investigation and diagnosis of their mimics.

    Abstract Dermatophytes are known as a common cause of superficial mycosis, but atypical presentations in immunosuppressed patients make the diagnosis more challenging. Here, we report a case of a 39-year-old patient, a renal transplant recipient from a living donor, who presented with atypical cutaneous lesions of lower extremities caused by Arthroderma gypseum (Nannizzia gypsea), four months after receiving a renal transplant. It is important to highlight the importance of the early detection of fungal infections in immunosuppressed patients. Clinicians should have a high degree of suspicion for the early detection and treatment of the cases.

    Abstract Chromoblastomycosis (CBM) is a fungal infection caused by fungi belonging to the order Chaetothyriales, and caused mainly by Fonsecaea pedrosoi. The classic treatment, based on itraconazole and/or terbinafine as well as physical approaches, is considered complex and ineffective due to the high rate of relapses. Thus, new strategies are needed to manage CBM; in this regard, the present work reports the evolution of lesions in patients successfully treated with imiquimod. Of note, classic treatment was not effective in healing the lesions of two of them, but single topical treatment with imiquimod healed the lesions.

    Abstract Tuberculosis verrucosa cutis is a rare medical condition that is caused by the inoculation of Mycobacterium tuberculosis into the skin of a previously sensitized individual. This clinical form of tuberculosis corresponds to 1-2% of all cases of tuberculosis and due to the paucibacillary characteristic of the lesions, patients can be misdiagnosed, accounting for the chronification of the skin infection. Herein, we report the case of a 26-year-old male farmer, presenting plaques with verrucosa and hyperkeratosis features in the left thigh and buttocks during 15 years. M. tuberculosis was identified by PCR and the patient was treated with standard anti-tuberculosis drugs, with subsequent improvement of the skin lesions.
