Erythema nodosum in sarcoidosis. Relationship with extrathoracic involvement and prognostic significance.

Introduction: Only a few studies analysed the prognosis significance of erythema nodosum (EN) in sarcoidosis. Our objective was to analyze the prevalence of EN in sarcoidosis, its possible association of EN with extrathoracic sarcoidosis, and its prognostic significance.

Methods: Retrospective study including patients diagnosed with sarcoidosis at Bellvitge University Hospital, Barcelona, Spain, between 1980 and 2017.

The knowledge and skills required for the onco-rheumatologist: Study of four-year consultation records of a high-volume cancer centre.

Objectives: Onco-rheumatology, the intersection of oncology and rheumatology, is an emerging field requiring further definition. This study aimed to identify the knowledge and skills essential for rheumatologists in clinical oncology.

Methods: We retrospectively reviewed consultations with the onco-rheumatology department of a high-volume tertiary cancer centre in Japan from January 2020 to December 2023.

Development of Behçet's disease on maintenance therapy for autoimmune hepatitis.

Behçet's disease is a clinical diagnosis with variable presentations. Liver involvement is rare in the absence of vascular complications. We describe a patient diagnosed with Hashimoto's thyroiditis and autoimmune hepatitis on azathioprine who developed extensive aphthous ulcers approximately 10 years later.

Progressive Neurosarcoidosis Presenting as Idiopathic Hypopituitarism With Atypical Radiological Features for 13 Years.

Sarcoidosis is an immune-mediated multisystem condition of unknown etiology, characterized by non-caseating granulomatous inflammation. While it commonly affects the lungs and the reticuloendothelial system, it can affect any organ. Most of such cases involve the central nervous system, but the condition rarely presents with symptoms related to hypothalamic-pituitary dysfunction.

Erythema nodosum followed by eosinophilic pneumonia as an adverse effect of dupilumab treatment in a patient with severe asthma.

Dupilumab is a monoclonal antibody that has recently been introduced for the treatment of asthma. It has the potential to significantly alter the progression and severity of T2 -dependent diseases, including severe asthma. However, dupilumab can cause transient hypereosinophilia.

Atypical Type 2 Lepra Reaction Masquerading as Recurrent Sweet Syndrome.

Erythema nodosum leprosum (ENL) is an immune complex-mediated response in Mycobacterium leprae infection, presenting with fever, arthralgias, and tender cutaneous lesions. It mimics Sweet syndrome (SS) clinically and histologically but requires distinct management. A 65-year-old man with recent travel presented with fever and edematous plaques.

Case Report: Acute Additive Polyarthritis as a Presentation of Type 2 Lepromatous Reaction: The Role of Differential Diagnosis.

Introduction: Type 2 lepromatous reaction is a severe complication triggered by proinflammatory cytokines, it affects patients with lepromatous leprosy and border lepromatous leprosy. This reaction can occur before, during, or after treatment.

Case Report: We report a case of acute polyarthritis as type 2 lepromatous reaction debut.

Sarcoid Vasculitis in the Skin: A Clinicopathologic Study of 8 Cases With Various Skin Lesions but the Common Unique Cannonball-like Vessel Destruction by Sarcoid Granulomas.

While the skin is a common target organ for sarcoidosis, cutaneous granulomatous vasculitis is rare among patients with sarcoidosis. Due to the lack of detailed studies on cutaneous sarcoid vasculitis, both dermatologists and pathologists remain unfamiliar with this rare but important vasculitic disorder. We clinicopathologically evaluated eight cases with biopsy-proven cutaneous vasculitis and cutaneous sarcoidosis and analyzed morphologic changes in the process of vasculitis for both small vessels and muscular vessels in detail.

Immune Markers and Inflammatory Cytokines in Granulomatous Lobular Mastitis: A Case-Control Study.

Purpose: Granulomatous lobular mastitis (GLM) has seen a rising incidence, though its pathogenesis remains unclear, posing challenges for treatment and contributing to high recurrence rates with conventional therapies. While the role of inflammatory and immune factors in GLM has been recognized, a comprehensive clinical evaluation of these markers is still lacking. This study aims to identify potential diagnostic markers and therapeutic targets by comparing immune markers and cytokine levels in GLM patients and healthy controls.

Hospitalist-performed skin biopsy in the diagnosis of skin disease.

In hospitalized patients, dermatologist intervention can lead to rapid identification and treatment of skin disease. However, many medical centers lack a specialized dermatologist, so skin biopsies might instead be performed by hospitalists. We aimed to determine the impact of skin biopsies performed by hospitalists on the diagnosis of skin conditions.

Skin as a Reflection of Gut Health: An Overview of Dermatological Manifestations in Primary Neoplastic and Autoimmune Gastrointestinal Disorders.

Gastrointestinal (GI) diseases can present with several extraintestinal manifestations, and cutaneous signs and symptoms are most frequent. Although conventionally GI and skin are considered two entirely separate organ systems, they are closely correlated in origin. An increasing amount of data highlights the complex relationship between GI and dermatological conditions.

[Erythema nodosum].

Erythema nodosum (EN) is the most frequently occurring form of acute panniculitis. It is characterized by painful red to livid raised nodules or bumps that typically occur symmetrically in the shin area. The cause of EN is often a reaction of the immune system to various triggers including infections, inflammatory diseases or medications.

Erythema Nodosum Secondary to CD5-Positive Diffuse Large B-Cell Lymphoma as a Paraneoplastic Symptom: A Case Report.

Introduction: Erythema nodosum (EN) is the most common form of panniculitis. EN can be idiopathic or secondary to an underlying systemic disease, infection, drug use, or tumor. CD5-positive diffuse large B-cell lymphoma (CD5+ DLBCL) is a relapsed and refractory lymphoma, and further understanding of its pathology is required.

Erythema nodosum as first clinical manifestation of metastatic neuroendocrine tumor: A case report.

Erythema nodosum (EN) is a reactive inflammatory panniculitis, which has been associated with medications, infections, autoimmune and autoinflammatory diseases. It has rarely been associated with neoplasms. We present the case of a 61-year old woman who was admitted because 3-week history of painful erythematous subcutaneous nodules on the lower limbs clinically consistent with EN, which was confirmed by skin biopsy.

Baggio-Yoshinari Syndrome: A Report of Five Cases.

Compared to classic Lyme disease (LD), Baggio-Yoshinari syndrome (BYS) has the following distinctive characteristics: it is transmitted in the Amazon area and Northeast, Central-West, Southeast, and South regions of Brazil by hard ticks, notably or sp. The absence of sp. ticks in areas at risk of BYS in Brazil is probably the main reason for the disease's differences from LD in the United States, Europe, and Asia.

Erythema nodosum manifestation of Parvovirus B19-associated reactive arthritis.

Introduction: Parvovirus B19 virus-mediated viral inflammation and immune-complex deposition generate mainly short-term manifestations in the affected individuals. The objective of this study was to determine Parvovirus B19 infection in rheumatoid arthritis (RA) patients.

Methodology: The study employed 50 patients diagnosed with RA and 30 healthy individuals.
