Intussusception is the telescoping of proximal loop of the bowel within distal loop resulting in obliteration of the lumen. Although it frequently occurs with the most common cause of intestinal obstruction in children, it is a rare phenomenon and an uncommon cause of acute intestinal obstruction in adults. Unlike pediatric intussusception, where the cause is idiopathic, adult intussusception is associated with underlying pathology as a lead point. The underlying pathology usually is malignant, but the prognosis is better when there is a benign lead point. The benign lead point intussusceptions are rare and are treated with reduction when there are no signs of ischemia. When there is ischemia or when reduction is not feasible, they are treated with surgical resection. In this report, we describe a rare case of an adult intussusception from a large colonic lipoma in a 79-year-old male, treated successfully with surgical resection.

Streptococcus intermedius is a beta‐hemolytic, non‐motile, catalase‐negative, gram‐positive member of the Streptococcus anginosus group. When compared to other members of this group like S. anginosus and Streptococcus constellatus, S. intermedius infections are more substantial. In this case, we present a 47‐year‐old male patient who was found to have S. intermedius abscesses in his lungs, liver, and brain. The treatment of choice for these abscesses is a combination of drainage, surgery, and antibiotic therapy.

Rhabdomyosarcoma is a malignant soft tissue sarcoma of primitive mesenchymal cells, showing varying degrees of striated skeletal muscle cell differentiation. It is a very common cancer of childhood and adolescence, but rarely seen in the adult population. Here, we present a case of a 33-year-old male presented with a poorly differentiated desmin positive alveolar rhabdomyosarcoma in the left arm. The prognosis of alveolar rhabdomyosarcoma in adults is very poor, frequently detected at advanced stages or with metastases. The alveolar subtype in particular has been found to have a more aggressive course with a high rate of metastasis. Recent studies have shown that using pediatric treatment guidelines resulted in better survival outcomes and local control, but the survival rates are still below that of the pediatric population. Newer studies are looking into using specific molecular markers for more targeted therapy in hopes of further improving survival rates in the adult population.
