Ultrasound in Emergency MedicinePoint-of-Care Ultrasound (POCUS) for Isolated Pediatric Dysuria: An Unusual Presentation of Acute Appendicitis.

Background: Isolated complaint of dysuria in an adolescent is a rare presentation for acute perforated appendicitis. Acute appendicitis typically involves vague periumbical pain that migrates to the right lower quadrant, associated with pain, nausea, and loss of appetite. There have been case reports of associated pyuria and dysuria in addition to classical symptoms, but to our knowledge, this is the first case with isolated dysuria presenting to an emergency department (ED).

Neurotropic Gamma-Delta T-Cell Lymphoma With CD30-Positive Lymphoid Infiltrates.

Primary cutaneous gamma-delta T-cell lymphoma (PCGD-TCL) is a clonal proliferation of gamma-delta T cells with a cytotoxic phenotype that is typically characterized by an aggressive clinical course with ulcerative plaques or subcutaneous nodules. In this report, the authors describe a patient who developed an ulcerated tumor on the left upper extremity and painful papules and nodules on the right lower extremity. Interestingly, several of the papulonodules on the right lower extremity underwent spontaneous involution.
