We present a case of the patient, who developed hypersensitivity reaction during the treatment of chronic lymphocytic leukemia. Bendamustine was suspected as a culprit agent. The patient as well as 3 controls underwent skin testing with the concentrations of the bendamustine described in earlier studies. We doubted the testing recommendations as all the controls developed serious local reactions. The clinical meaning of the positive skin test reaction in the patient remained unclear and questioned the safeness of recommended testing concentrations as in certain situations wrong diagnosis could be made or even harm could be done. Future investigations are needed when allergy to bendamustine is suspected.

Background: The main technique for identification of free flap perforator vessels is Doppler sonography, which is not always accurate, user dependent and affected by the patient's body habitus.
Methods: Adult patients undergoing head and neck resection and free flap reconstruction at two academic institutions were enrolled. Doppler sonography was used to identify perforators, and were marked using a skin marker.

Historically, adolescents and young adults diagnosed with acute lymphoblastic leukemia (ALL) have faced lower survival rates compared to children with the same illness. Bullous pemphigoid (BP), a rare autoimmune skin disorder, poses unique challenges when occurring alongside hematologic malignancies. A 23-year-old male with ALL-L1 diagnosis who developed bullous pemphigoid in this report.

In alignment with the global movement toward reducing animal testing, several reconstructed human epidermis (RHE) models have been created for conducting skin irritation tests. These models have undergone development, verification, validation, and integration into OECD TG 439. Our team has introduced a novel in-house RHE named GB-RHE, and we adhere to OECD TG 439 to pre-validate the model and test its potential employment for nanoparticle irritation studies.

The objective of this study is to describe the clinical and histologic features of a dog that developed anterior uveitis and uveal depigmentation in association with vitiligo. A 3-year-old, female-spayed, Bernese Mountain Dog with a history of bilateral idiopathic anterior uveitis developed iris depigmentation, leukotrichia, and skin depigmentation. The initial diagnostic evaluation for uveitis was unremarkable, including general bloodwork, urinalysis, infectious disease testing, thoracic radiographs, and abdominal ultrasound.
