AI Article Synopsis
- Post-COVID-19 vaccination, increased 18F-FDG uptake in lymph nodes has been noted in PET/CT scans.
- A breast cancer patient showed increased uptake in specific lymph nodes shortly after receiving the vaccine in the thigh.
- Doctors should recognize this uptake pattern as potentially related to vaccination, especially when using the thigh as an injection site.
Article Abstract
Since worldwide COVID-19 vaccination, 18F-FDG uptake in reactive axillary lymph nodes has been frequently observed in PET/CT studies. We describe a patient with breast cancer who underwent 18F-FDG PET/CT 7 days after receiving COVID-19 vaccination in the right thigh. 18F-FDG uptake was observed in nonenlarged right-sided inguinal, iliac, and para-aortic lymph nodes. As the thigh can be used as an alternate site for COVID-19 vaccine injection in case of lymphedema in both arms or for adequate axillary staging in patients with breast cancer, physicians should be aware of such 18F-FDG uptake pattern.

Aim: Sympathetic overactivation may lead to severe ventricular arrhythmias (VAs) post-myocardial infarction (MI). The superior cervical ganglion (SCG) is an extracardiac sympathetic ganglion which regulates cardiac autonomic tone. We aimed to investigate the characteristics and functional significance of SCG on neuro-cardiac communication post-MI.

We report the case of an 18-month-old boy who developed a phototoxic skin reaction to terbinafine on his scalp, ears, and face in the form of disseminated erythematous plaques, which resembled subacute lupus erythematosus (SCLE) in their clinical presentation. Skin changes appeared a short time after the boy was exposed to sunlight during the period of time when he was treated with oral terbinafine due to Microsporum canis fungal scalp infection. Tinea capitis is a common dermatophyte infection primarily affecting prepubertal children (1).

N staging systems are paramount clinical features for colorectal cancer (CRC). In N1 stage (N1) CRC, patients present with a limited number of metastatic lymph nodes, yet their prognoses vary widely. The tumor invasion proportion of lymph nodes (TIPLN) has gained attention, but its prognostic value in N1 CRC remains unclear.

The involvement of axillary lymph nodes (ALNs) is a critical prognostic factor affecting patient management and outcomes in breast cancer (BC). This study aims to comprehensively analyze the clinical data of BC patients, evaluate ultrasonic signs of ALNs, and explore the implications of a prediction model for ALN metastasis (ALNM) in early-stage BC patients based on ultrasonic features and clinical data. This study retrospectively analyzed ultrasonic features and clinical data from 216 patients diagnosed with unilateral invasive BC.

Objective: To analyze the clinical characteristics and molecular biomarkers of adult T-cell lymphoblastic lymphoma (T-LBL) to identify prognostic factors, and to evaluate the efficacy of different chemotherapy regimens, providing a basis for optimizing treatment strategies for T-LBL.
Methods: A total of 89 Patients aged 18-72 years with T-LBL, confirmed via histopathological examination of lymph nodes, extranodal tissues, or bone marrow, were retrospectively included. Clinical data, treatment details, and mutational profiles were collected.
