RESUMO
Acquired hemophilia A is a rare bleeding diathesis most typically seen in systemic rheumatic disease, solid and hematologic malignancies, and pregnancy. We present a case of this condition that occurred immediately after vaccination against SARS-CoV-2 with the mRNA-1273 (Moderna) vaccine.
RESUMO
The low prevalence rate and limited literature on eccrine carcinoma (EC) pose a challenge to properly diagnosing and treating this rare malignancy. EC lesions tend to present similarly to other cutaneous neoplasms and dermatitis-like conditions. Efficacious treatment guidelines have not been established for patients diagnosed with EC, and few treatment regimens have demonstrated clinical benefit. Due to the high metastatic potential of EC, recognizing the clinical presentation, properly diagnosing, and utilizing beneficial treatment options are important for managing this disease. We report a case of a 66-year-old female who presented with lesions that her primary care provider misdiagnosed as basal cell carcinoma. The disease responded poorly to taxane- and platinum-based chemotherapies as well as an isolated limb perfusion of an alkylating agent. However, continuous dosing of oral capecitabine achieved an 18-month period of progression free survival (PFS) and ameliorated quality of life. We wish to highlight this rare disease and discuss presentation, diagnosis, and management as it is most often misdiagnosed leading to advanced metastatic disease when patients present to the oncologist. In addition, it is crucial to study and report potentially efficacious regimens considering the lack of clinical trials in this disease.
RESUMO
PURPOSE: To establish the maximum tolerated dose (MTD) and safety profile of bi-weekly Pemetrexed (PEM) when combined with weekly cisplatin (CDDP) and standard dose external beam radiation (EBRT) in patients with locally advanced or metastatic esophageal and gastroesophageal junction (GEJ) carcinomas. METHODS: We conducted an open label, single institution, phase I dose escalation study designed to evaluate up to 15-35 patients with advanced or metastatic esophageal and GEJ carcinomas. RESULTS: 10 patients were treated with bi-weekly PEM, weekly CDDP, and EBRT. The MTD of bi-weekly PEM was determined to be 500 mg/m(2).
