5-Fluorouracil (5-FU), a pyrimidine analogue, is widely used in different chemotherapy regimens with established indications for the treatment of gastrointestinal, breast, head, and neck tumors. Various prospective studies including randomized controlled trials and retrospective reviews have shown a wide range of reported incidence of cardiotoxicity related to 5-FU use. This incidence is dependent on drug regimen, doses, concomitant therapy, patients' clinical characteristics, and risk factors. Herein, we present a clinical case of coronary vasospasm mimicking ST-elevation myocardial infarction during a 5-FU infusion for salivary gland cancer. Cardiologists and oncologists must keep in mind the potential life-threatening side effects of 5-FU on the heart and they must be familiar with the risk factors for their occurrence and their management strategies.

Tick salivary proteins are crucial for efficient and successful tick feeding. Most of them are still uncharacterized, especially those involved in the formation of tick cement. Tick salivary protein PA107 is a putative cement protein, which is transcribed in salivary glands during the initial phase of tick feeding.

Salivary gland diseases encompass a broad range of conditions, including autoimmune, inflammatory, obstructive, and neoplastic disorders, significantly impacting oral health and overall well-being. Recent research has highlighted the crucial role of exosomes, small extracellular vesicles, in these diseases. Exosomes mediate intercellular communication by transferring bioactive molecules such as proteins, microRNAs, and lipids, positioning them as potential diagnostic biomarkers and therapeutic agents.

Metastasizing pleomorphic adenoma is a rare entity that has the propensity for distant metastasis despite being histologically benign. We report the case of a 56-year-old woman with a long-standing right upper neck swelling and a recent-onset swelling over the left side of the scalp. Clinical workup did not reveal any other tumor deposits in the body.

Retinoic acid (RA) signaling plays multiple essential roles in development of the head and face. Animal models with mutations in genes involved in RA signaling have enabled understanding of craniofacial morphogenic processes that are regulated by the retinoid pathway. During craniofacial morphogenesis RA signaling is active in spatially restricted domains defined by the expression of genes involved in RA production and RA breakdown.
