Article Abstract
Background: Scalp, tongue and/or lip necrosis are rare complications of GCA.
Objectives: To describe characteristics and outcome of patients with giant cell arteritis (GCA) -related scalp, tongue and/or lip necrosis.
Methods: A retrospective nationwide multicenter study included 20 GCA patients with scalp, tongue, and/or lip necrosis diagnosed between 1998 and 2021 and 80 GCA control patients matched for age, sex and management period. Logistic regression analyses were conducted to identify baseline characteristics associated with scalp, tongue and/or lip necrosis.
Results: Compared to controls, patients with scalp, tongue and/or lip necrosis showed significantly more cranial manifestations (headache, p=0.045; scalp tenderness, p=0.006; jaw claudication, p=0.02). No differences were observed between both groups regarding the occurrence of visual symptoms or large vessel involvement. At diagnosis, GCA patients with necrosis more likely received IV methylprednisolone infusions and higher doses of oral prednisone. There were no differences regarding vascular complications during follow up. Compared to controls, survival was decreased in GCA patients with necrosis (p=0.003). In a multivariable logistic regression model, scalp tenderness [odds ratio (OR) 4.81(95 % CI: 1.57, 14.79), p = 0.006] and cognitive disorder [OR 6.42 (95 % CI: 1.01, 40.60), p=0.048] were identified as factors associated to scalp, tongue, and/or lip necrosis.
Conclusion: Our results suggest that scalp, tongue, and/or lip necrosis is associated to higher mortality in GCA patients. Scalp tenderness and cognitive disorder were significant factors associated to this very rare complication of GCA.

A Clinical Case of Methotrexate Toxicity.

Internal Medicine Department, Unidade Local de Saude de Sao Joao, Alameda Professor Hernani Monteiro, 4200-319 Porto, Portugal.
Methotrexate is a commonly prescribed immunosuppressant and chemotherapy agent, carefully monitored by healthcare providers due to its potential adverse effects. As a result, methotrexate toxicity is relatively rare. We present the case of a 79-year-old man followed in rheumatology for symmetrical polyarthralgia, who inadvertently took methotrexate 10 mg daily, instead of weekly, leading to methotrexate toxicity.

Introduction And Importance: Glial heterotopia (GH) is a rare congenital lesion characterized by the presence of normal glial tissue in extracranial sites with no connection to the central nervous system. Oropharyngeal occurrence is very rare. The aim of this case report is to emphasize that oropharyngeal glial heterotopia can present as a large mass causing airway obstruction.

Objective: The increasing use of imaging techniques, particularly 18F-FDG PET-CT, together with autopsy findings, has significantly expanded our understanding of the clinical spectrum of giant cell arteritis (GCA). This study aimed to assess the frequency and spectrum of non-classical manifestations and other infrequent complications of the disease METHODS: This retrospective study analyzed a consecutive cohort of 174 patients with proven GCA diagnosed between 2005 and 2024.
Results: Among 174 GCA patients, 52 (29.
Extensive Muscular and Subcutaneous Metastases in Moderately Differentiated Squamous Cell Carcinoma of the Tongue: A Case Report.

This report details a unique case of extensive muscular and subcutaneous metastasis in the setting of moderately differentiated squamous cell carcinoma of the tongue, diagnosed in a 70-year-old male. The patient presented with a painless ulceration of the tongue, non-specific swelling of both soft tissue on the scalp, chin and upper left arm, as well as unintentional and continued weight loss. While metastatic squamous cell carcinoma of the tongue will usually follow the classic pattern of metastasizing to the lungs, liver and bones, this case presented with broad soft tissue involvement of the scalp, skeletal muscle and subcutaneous tissue.

Objectives: This study seeks to create consensus-based definitions of signs and symptoms of giant cell arteritis (GCA) for use by health care professionals, primarily in research settings.
Methods: Core definitions of signs and symptoms of GCA were extracted from 11 randomised controlled trials of GCA previously reviewed in a systematic literature review conducted in the context of the development of response criteria for GCA. This information was supplemented by definitions from other sources, such as rheumatology textbooks.
