Hematoma, Hemarthrosis, and Hemotympanum: A Case Report of Acquired Hemophilia A
DOI: https://doi.org/10.5070/M5.52344Non-contrast computed tomography (CT) scan of the left knee confirmed a small to moderate suprapatellar joint effusion with Hounsfield unit measurements suggestive of blood products (+47 Hounsfield units), consistent with acute hemarthrosis. The hemarthrosis appears as a gray, fluid-density collection slightly darker than the surrounding tissues that conforms to the suprapatellar space anterior to the femur, continuing distally between the femur and the patella.
The Rash That Didn’t Blanch: A Case Report of Adult-Onset IgA Vasculitis with Underlying Cirrhosis and IgA Nephropathy
DOI: https://doi.org/10.5070/M5.52253Given the patient’s physical exam findings of tender palpable purpura to the lower extremities, dermatology was consulted for suspicion of acute small vessel vasculitis. A punch biopsy for hematoxylin and eosin (H&E) stain and direct immunofluorescence (DIF) was subsequently performed. The H&E demonstrated nonspecific purpura.
Open Chest Wound with Sternal Fracture in the Emergency Department, a Case Report
DOI: https://doi.org/10.5070/M5.52202The image demonstrates the large chronic-appearing wound of the patient’s anterior chest as well as the visible fractured segments of the patient’s exposed sternum. The sternum is necrotic appearing concerning for a chronic process including osteomyelitis and malignancy. Purulent drainage is visible on the wound consistent with an infectious process.
Effects of Volume Overload: A Case Report of an Edema Bulla
DOI: https://doi.org/10.5070/M5.52206This image shows a large edema bulla on the patient's right shin. The bulla is 10 x 10 cm, filled with serous fluid, has a spontaneously occurring defect in the skin of the superior portion of the bulla, and is non-erythematous. The bulla is much larger than the 1-5 cm edema bullae described in the literature. As edema bulla is primarily a clinical diagnosis, taking the full history and physical exam into account is essential to recognize these bullae.
Case Report of a Dermatologic Reaction to Wound Closure Strips and Liquid Adhesive
DOI: https://doi.org/10.21980/J8.52256The patient removed the splint, and the wound were notable for erythematous bullae (blue arrow), blisters (yellow arrow), and skin maceration (red arrow) in the distribution under the wound closure strips. Of note, there was no surrounding erythema with poorly defined borders.
Metastatic Calcinosis Cutis in the Emergency Department: A Case Report
DOI: https://doi.org/10.21980/J87Q00X-ray imaging was obtained of the left elbow and showed soft tissue calcium deposits. Radiology stated, “massive periarticular calcinosis of renal failure obscures fine osseous detail. Several of the largest calcifications have decompressed since the prior exam and may contribute to the drainage observed clinically. Superimposed infection is not excluded.” X-rays with an asterisk are the comparison images from two months previous to the visit. Areas of decompression are highlighted in blue demonstrating that some of the larger calcified nodules are no longer present.
A Case Report of Calciphylaxis
DOI: https://doi.org/10.21980/J8KW8VOn arrival for this visit, the patient was nontoxic appearing with stable vital signs. The physical exam was notable for deep, ulcerated, bilateral anterior leg wounds with purulent drainage and large areas of eschar (see photographs).
A Case Report on an Elusive Incident of Erythema Multiforme
DOI: https://doi.org/10.21980/J8BM0WHer physical exam was notable for multiple scattered tense vesicles on an erythematous base along the left and right lower extremities and right upper extremity. The lesions were excoriated and in different stages of evolution. No oral, mucosal, or conjunctival lesions were found. Physical exam was otherwise unremarkable.
