Recurrent Cutaneous Squamous Cell Carcinoma with Direct Invasion of the Pleura: A Case Report.

Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer in the United States, second only to basal cell carcinoma. While majority of patients have a favorable outcome after surgical resection, a subset of patients carry a higher risk of local recurrence, distant metastasis, and mortality. In this article, we present an unusual case of a 54-year-old male who had trunk cSCC at the site of burn wound that recurred after surgical resection and radiotherapy. Interestingly the cSCC disease recurrence presented with respiratory symptoms secondary to malignant pleural effusion from direct invasion of pleura as the tumor eroded through the chest wall. The patient died within a few weeks from progressive disease. Despite the high incidence rate of cSCC, there is a paucity of randomized controlled trials to guide evidence-based management of cSCC in recurrent and metastatic disease.

Misdiagnosis of myasthenia gravis presenting with tongue and palatal weakness.

We discuss the case of an elderly male who presented with a history of dysphagia, dysphonia, palatal weakness and a sensation of tongue swelling, each symptom of varying time duration. Myasthenia gravis may have a variety of presentations that include ocular fatigability, respiratory muscle weakness and bulbar symptoms. The variety of these myasthenic syndromes can serve as a barrier to diagnosis and can often result in delayed or incorrect diagnosis. In this report, we present an atypical presentation of a relatively rare condition.

Delayed Diagnosis of Atypical Presentation of Myasthenia Gravis.

Myasthenia gravis is an autoimmune disorder affecting the neuromuscular junction, resulting in muscle fatiguability and weakness. The pathological characteristics of the disorder include ocular weakness resulting in diplopia and/or ptosis. More generally, the disease can result in fluctuant weakness of skeletal muscle, predominantly affecting ocular, bulbar and respiratory muscles. Autoimmunity in this instance is mediated by IgG anti-acetylcholine receptor antibodies that results in an impaired structure of postsynaptic neurotransmission. Approximately 15% of patients with myasthenia gravis present with bulbar symptoms, of which isolated bulbar symptoms are seen only on occasion. As with our patient, this presentation is most commonly seen in men with late-onset myasthenia gravis. We present a case of an 83-year-old male who presented with a 1 year history of dysphagia for solids and fatigable dysarthria. Following a diagnosis of myasthenia gravis, he was initiated on corticosteroid treatment. He later descended into myasthenic crisis, requiring invasive ventilation measures due to a failure of both non-invasive ventilation and intravenous immunoglobulin G (IVIG) to achieve therapeutic goals. LEARNING POINTS: Isolated bulbar symptoms in an elderly man warrants consideration of myasthenia gravis to be included in the differential diagnosis.There is possibly an increased risk of myasthenic crisis in late-onset isolated bulbar myasthenia gravis.Empirical treatment for myasthenia gravis must be administered within a hospital setting, paying attention to respiratory tract infection and corticosteroid treatment as triggers for myasthenic crisis.
