RESUMEN
Myasthenia gravis (MG) is an autoimmune illness that causes neuromuscular junctions to be damaged by anti-acetylcholine receptor antibodies. It is a very rare condition that is more common among women. Fatigable fluctuating diplopia or ptosis is the characteristic early appearance of this condition. Dysphagia or dysphonia may be present in rare cases. This illness can affect any group of skeletal muscles, including those in the neck and upper limbs. It can also affect the muscles that help you breathe, which can lead to breathing failure. We present a case of a 20-year-old female diagnosed with mixed connective tissue disease presenting with acute respiratory failure as the initial presentation of MG. Clinicians have to have a high index of suspicion for myasthenia when patients arrive with fatigable muscle weakness. This will cut down on the amount of money spent on investigations and the risk of morbidity.
RESUMEN
Rhabdomyosarcoma (RMS) is a common soft tissue tumor in adults, but RMS's causes and risk factors are unknown. We present a case of a 62-year-old man with RMS who presented with feelings of fullness after meals and vomiting for the previous five months with anorexia and weight loss for four months. He reported feeling a rolling mass in his belly that moves from left to right. He was initially diagnosed with gastric outlet obstruction due to stomach carcinoma. During the surgical operation, we noted the gross appearance was unlike typical adenocarcinoma or lymphoma of the stomach. Histopathological evaluation of the specimen confirmed a diagnosis of primary epithelial RMS of the stomach. When treating RMS, expertise in immunohistochemistry, molecular biology, genetics, or ultrastructure may be necessary. Information on the appropriate laboratory investigations and management protocol is limited, but an early diagnosis can change the course of treatment and improve patient outcomes.
