We encountered an unusual case of pemphigus foliaceus in which there were early clinical signs of dermatitis herpetiformis with eosinophilic spongiosis histologically. Numerous authors have appreciated that eosinophilic spongiosis occurs in early pemphigus foliaceus, usually in the preacantholytic stage when the lesions may clinically simulate dermatitis herpetiformis. Recognition of eosinophilic spongiosis may help differentiate early pemphigus from other vesiculobullous disorders.

Background: Allergic contact dermatitis cannot be reliably differentiated from other forms of spongiotic/eczematous dermatitis by histology alone. Textbooks and recent studies have variably supported the specificity of dermal eosinophils, eosinophilic spongiosis, and Langerhans cell collections, among other features.
Objective: To assess which histopathologic features favor a diagnosis of allergic contact dermatitis.

Background: Folliculotropic mycosis fungoides (FMF) is a rare cutaneous malignancy that can be mistaken for inflammatory diseases, such as discoid lupus erythematosus (DLE), due to the variability of histopathological findings.
Methods: This study aims to provide dermatopathologists with evidence-based histopathologic criteria to distinguish DLE from FMF by reporting overlapping and distinguishing microscopic features. Forty-three biopsies from patients with a confirmed diagnosis of DLE or FMF were graded for the presence or absence of 18 histopathologic features.

Introduction: Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a potentially life-threatening, drug-induced adverse reaction characterized by skin eruptions, lymphadenopathy, fever, and a broad range of other bodily manifestations. The spectrum of histopathologic and clinical presentations is wide; therefore, DRESS syndrome can mimic other diseases.
Case Presentation: We present a case of a 4-year-old male patient who started chemotherapy with vincristine, cytarabine, and etoposide.
Introduction: Lymphocytic esophagitis (LyE) is a rare esophageal disorder of unknown etiology, characterized by dense peripapillary lymphocytes without neutrophils or eosinophils, and spongiosis. Patients typically present with symptoms such as dysphagia or chest pain. Here, we describe a notable case of lymphocytic esophagitis in a patient who presented with food impaction.
