Morbihan disease: A diagnostic dilemma: two cases with successful resolution

Morbihan syndrome is a rare entity characterized by persistent erythema and solid edema of upper two-thirds of the face. Although its etiology is poorly understood, it is known to have a wide differential diagnosis and is frequently under-recognized.1–3 We report two such cases of Morbihan syndrome in patients that responded well to treatment with a combination of 2.5% hydrocortisone cream, brimonidine 0.33% topical gel, metronidazole gel and 100 mg doxycycline twice daily. This report emphasizes the necessity of biopsy for clinical correlation in cases of chronic facial edema. It also serves to highlight a potential association of Morbihan syndrome to diabetes mellitus through recently discovered pathophysiology of diabetes on the lymphatic system. It underscores the effectiveness of our therapeutic regimen in the context of other treatment regimen effectiveness. Finally, it highlights novel advances into the diagnosis and treatment of the disease.OA publication support through Carolina Consortium agreement with Sag

Primary Malignant Melanoma of the Gastric Antrum: A Case Report

Primary melanoma of the antrum is a rare and aggressive disease. Diagnosis requires a correlation between the patient's history, tumor histopathology, and immunohistochemistry. Surgery and mutation‐targeted treatments may improve overall survival

Orbital mantle cell lymphoma presenting as myasthenia gravis

<p>A 69-year-old man, previously treated with pyridostigmine for myasthenia gravis (manifesting as ptosis and diplopia) was evaluated for several concomitant bilateral anterior orbital masses. Imaging revealed 3 discrete, solid masses within and around the orbits. An incisional biopsy demonstrated atypical lymphocytes positive for CD20 and Cyclin-D1, consistent with mantle cell lymphoma. The patient received induction chemotherapy with a rituximab-based regimen. He experienced resolution of his diplopia and ptosis after one cycle of chemotherapy and achieved complete remission of the orbital masses and myasthenia symptoms after 6 cycles. Myasthenia gravis is most commonly associated with thymoma, but may also be observed with other malignancies. Recognition that orbital lymphoma may coexist with myasthenia gravis will help in expediting the diagnosis of future cases and in guiding treatment decisions.</p

Sipuleucel‐T associated inflammatory cardiomyopathy: a case report and observations from a large pharmacovigilance database

International audienceAims: The major cardiovascular (CV) adverse effects observed with sipuleucel-T from large multi-institutional clinical trials included thromboembolic events, myocardial infarction, and congestive heart failure in up to 0.3% of patients with CV risk factors. The incidence, outcomes, and mechanisms in real-world clinical settings of these CV adverse effects to date have not been fully elucidated. Our study identified a patient with sipuleucel-T-induced inflammatory cardiomyopathy, which led to the identification of CV adverse effects associated with sipuleucel-T from a large pharmacovigilance database and elucidation of its potential mechanisms.Methods and results: Using the MedDRA term 'cardiac disorders' (System Organ Class level), CV adverse events associated with sipuleucel-T versus all other drugs were reviewed from VigiBase, a large pharmacovigilance database. Disproportionality analysis was calculated by the information component (IC), a Bayesian disproportionality indicator. A positive IC025 (IC 95% lower end credibility interval) value (>0) is the traditional threshold used in statistical signal detection at the Uppsala Monitoring Centre. From VigiBase, the total number of CV adverse drug reaction reported with sipuleucel-T was 306 out of a total of 22 980 104 adverse drug reactions in VigiBase on 10/25/2020. MedDRA preferred terms levels were grouped into major CV adverse drug reaction categories where we observed significant reports of myocardial ischaemia, supraventricular tachycardia (particularly atrial fibrillation/atrial flutter), congestive heart failure, and valvular disorders. Myocardial ischemia included acute myocardial infarction (IC025 2.3) with n = 4/26 (15%) of these individual case safety reports considered fatal. Among patients with 'cardiac failure congestive' (IC025 1.5), 11 of these 43 cases (26%) were fatal with 42 (98%) of these cases considered to be solely due to sipuleucel-T.Conclusions: Patients with CV risk factors who are receiving sipuleucel-T may be at higher risk for congestive heart failure, myocardial ischemia, and supraventricular tachycardia. Electrocardiograms during weekly sipuleucel-T infusions and left ventricular function monitoring with echocardiogram should be considered in these patients. Our findings are suggestive of another rare presentation of T-cell-mediated CV toxicity with cancer immunotherapy
