A Rare Case of Anti-TIF-1γ Antibody Positive Dermatomyositis in Adulthood.

Dermatomyositis (DM) presents with inflammatory myopathy and distinct skin manifestations, often linked to specific autoantibodies. Anti-transcriptional intermediary factor-1 gamma (TIF-1γ) antibodies (Abs) are typically linked to DM in older patients and malignancy in 15% to 40% of cases. We highlight a case of a 24-year-old female who presented with weakness of proximal muscles, periorbital edema, heliotrope rash, erosions on oral mucosa, and painful scaly rash on the lower extremities. Transcriptional intermediary factor-1 gamma Abs were positive, confirming inflammatory myopathy. Treatment with steroid pulse therapy and immunoglobulin led to improvement. Evaluation for malignancy yielded unremarkable results. This case underscores the importance of recognizing and managing DM with TIF-1γ Ab positive, even in atypical demographics, and highlights the need for comprehensive malignancy evaluation.

A Patient Develops Bullous Rash After Receiving the Second Dose of COVID-19 Vaccine.

Our knowledge about the clinical spectrum of COVID-19 has continued to evolve. The clinical features of the infection and vaccine are continuously updated. We present a case of bullous pemphigoid after receiving a second dose of the COVID-19 vaccine. This case highlights autoimmune skin findings seen in a patient after COVID-19 vaccination. A 70-year-old male presented with the chief complaint of blistering skin rash. He received his second dose of Pfizer COVID-19 vaccine two days before developing a painful pruritic maculopapular rash that started on his hands and extended proximally to his trunk. Physical exam was remarkable for tense bullae with negative Nikolsky sign. Biopsy and direct immunofluorescence lead to the diagnosis of bullous pemphigoid. The lesions improved significantly with steroids. Various cutaneous eruptions have been reported with Moderna and Pfizer COVID-19 vaccines, including the new onset of bullous pemphigoid. Based on our case, we suggest that bullous pemphigoid after COVID-19 vaccination is responsive to steroids and the prognosis is excellent. Understanding the clinical course and prognosis of bullous pemphigoid from the COVID-19 vaccine is of significant importance as we strive to keep our patients and communities safe. More data is needed to better guide recommendations, but so far looking at the example from our case, the benefits of COVID-19 vaccination seem to outweigh the risks. Therefore, patients should be advised to continue with future vaccinations.

An Atypical Presentation of Hemosuccus Pancreaticus Manifesting as Hematochezia.

Hemosuccus pancreaticus is a rare cause of upper gastrointestinal bleeding that is often associated with chronic pancreatitis. The bleeding usually manifests as melena because the source originates superior to the ligament of Treitz. We present a patient who was admitted for acute-on-chronic pancreatitis and ultimately developed hematochezia. Endoscopy revealed active oozing at the minor duodenal papilla. Computed tomography angiography identified active contrast extravasation at the gastroduodenal artery, and it was managed successfully with angioembolization. Our case emphasizes clinicians to consider hemosuccus pancreaticus as an alternative differential in a patient with a history of chronic pancreatitis manifesting with hematochezia.
