Intraluminal Small Bowel Metastasis From Primary Lung Cancer.

Lung cancer is the leading cause of cancer-related death worldwide, with frequent metastases to the brain, liver, adrenal glands, and bone. The incidence of intraluminal small bowel metastases of the lung is extremely rare and poorly documented within the literature. Few case studies have been published since the late 1980s and early 1990s. However, little is known about this rare form of metastasis. Small bowel metastatic disease has atypical symptoms that mimic a variety of other diseases; as a result, signs and symptoms may be overlooked until the disease has progressed to a late stage. Signs of small bowel obstruction, symptomatic anemia, abdominal pain, and peritonitis are commonly reported signs and symptoms. Various modalities can be utilized for the workup of suspected small bowel metastasis, including positron emission tomography, computed tomography, and various forms of endoscopy. The prognosis for lung cancer patients with intestinal metastases is poor, with many only surviving months to a few years after diagnosis. Therefore, it is critical to consider small bowel masses as a differential diagnosis in a patient with primary lung cancer who demonstrates clinical signs consistent with symptomatic anemia secondary to gastrointestinal (GI) bleeding, peritonitis, or small bowel obstruction. We report an unusual case of intraluminal and fungating small bowel masses in a patient who had previously undergone lung resections and chemo-immunotherapy. She was diagnosed with non-small undifferentiated carcinoma with tumor necrosis over 12 years before disease recurrence in the bilateral lungs, right adrenal gland, bone, and small bowel. The discovery of the small bowel metastases occurred while undergoing treatment for advanced-stage disease. At this time, she completed chemo-immunotherapy and remained on maintenance immunotherapy. The patient also underwent a partial right adrenalectomy and radiotherapy to the right adrenal gland. Given that she was experiencing symptomatic anemia and further workup indicated that the GI masses were causing her anemia, she underwent palliative small bowel resection of the masses. The pathology results demonstrated that the masses originated from her primary lung cancer, confirming metastatic disease to the small bowel.

Perioperative Interventions to Reduce Surgical Site Infections: A Review.

Surgical site infections (SSIs) contribute to increased health care costs and morbidity after procedures as well as prolonged length of stay. Perioperative personnel can use a variety of interventions to help reduce SSI incidence; however, all strategies are not effective for all patients (eg, antibiotic prophylaxis). Results of randomized controlled trials show that some SSI reduction strategies are generally effective, including preoperative skin antisepsis with an alcohol-based agent, closing surgical wounds with triclosan-coated suture, and applying a negative pressure wound therapy device to open and closed wounds. Study results do not show that irrigating clean wounds with crystalloid solutions containing antibiotics or routinely using plastic drapes with or without impregnated iodophor or silver nylon-impregnated dressings significantly reduces SSI incidence. Perioperative leaders should support the implementation of strategies to prevent SSIs and work with interdisciplinary team members to develop an SSI prevention bundle that will meet the needs of their patients.

Scalp Leiomyosarcoma: Diagnosis and Treatment During a Global Pandemic With COVID-19.

Leiomyosarcoma is an aggressive, uncommon sarcoma effecting smooth muscle tissue. Prompt tissue diagnosis and staging workup are keys to preventing distant metastasis. Identification of this rare sarcoma has become increasingly difficult with decreased ability to seek out non-coronavirus disease 2019 (COVID-19) medical care. The pandemic has caused a widespread healthcare demand with providers reaching their full capacity causing care and resources to be shifted to the pandemic. We have experienced an 83-year-old male who significantly delayed to seek any medical attention for his scalp lesion for several months due to a combination of fear and decreased available appointments. Since the patient presented with a delayed scalp leiomyosarcoma, he required an extensive excision and flap reconstruction for the lesion. This case sheds light on the importance of weighing the risks and benefits associated with cancer management during the pandemic for both patients and healthcare providers. The healthcare system's response to the pandemic also played a role in this case as well, with shorter appointment times and decreased frequency of follow-up. As a result, the pandemic has had a catastrophic impact on the diagnostic pathway for cancer. This case report discusses the difficulties in diagnosing and treating a rare cancer such as scalp leiomyosarcoma amidst the global pandemic and the importance of telemedicine in improving future outcomes.

Immunoglobulin G4-Negative Inflammatory Pseudotumors of the Pancreas.

Inflammatory pseudotumor (IPT) can occur in any organ, but rarely shows pancreatic involvement. While surgical excision has been recommended as the primary treatment for IPT of the pancreas in the past, some authors suggest observation while medical management often results in regression. Corticosteroids, nonsteroidal anti-inflammatory drugs and immunosuppressive therapy have been used to treat IPTs. Spontaneous regression has also been reported in IPT managed without surgical intervention. A 62-year-old female was evaluated for worsening abdominal pain and a mass in the neck of the pancreas that was identified on ultrasound. Further imaging with magnetic resonance imaging revealed a pancreatic mass with dilated pancreatic duct and an atrophic parenchyma of the pancreatic neck. Her serum tumor markers were not elevated. As this lesion appeared to be resectable pancreatic cancer based on cross-sectional imaging, no biopsy was performed prior to surgical resection. Distal pancreatectomy and splenectomy was recommended and the patient desired to proceed. Her recovery was uneventful with no postoperative complications, including pancreatic fistula. Final pathology revealed a lesion consistent with the diagnosis of immunoglobulin G4 (IgG4)-negative IPT without neoplasm. IPT of the pancreas is a difficult entity to diagnose and treat due to clinical and imaging characteristics closely resembling pancreatic adenocarcinoma. Biopsy with immunohistochemical analysis can be useful in diagnosing IPT; however, symptomatic lesions and concerning findings on cross-sectional imaging may warrant more definitive surgical intervention.

Recurrent lymphoepithelial cysts after parotidectomy in an undiagnosed HIV-positive patient.

A benign lymphoepithelial cyst (BLEC) is defined as a rare, benign lesion composed of single or multiple cysts found within salivary glands or the lateral cervical area. Increasing reports suggest an association between BLEC and human immunodeficiency virus (HIV), although its pathogenesis remains unclear. We report a 51-year-old male who presented with recurrent bilateral BLECs after initial parotidectomy of cyst. An HIV panel was then performed with a positive result. We review the surgical and medical managements of BLEC while also discussing further treatment recommendations. Clinicians should be aware that BLEC recurrence postparotidectomy may be the initial presenting symptom of HIV in a patient with no risk factors.

Intersphincteric proctectomy for rectal mucocele in a Crohn's patient with anal stenosis. A case report and review of literature.

In patients who have undergone a colonic resection with creation of an end colostomy, drainage of mucus secreted by the mucosa of the rectal stump may not be possible if there is an outlet obstruction. With an outlet obstruction, formation of a rectal mucocele occurs. A rectal mucocele is a rare condition which has only been reported sporadically in case reports. We present here the utility of an intersphincteric proctectomy for treatment of a rectal mucocele in a 47 year old male Crohn's patient resulting in negligible post-operative or long-term morbidities.

Chylothorax after blunt trauma.

Presented is a 50-year-old female who sustained a rare blunt traumatic chylothorax. Traumatic chylothoracies are usually the result of penetrating trauma and disruption of the thoracic duct. Diagnosis and treatment are discussed. The diagnosis is sometimes difficult in the trauma setting due to the possible presence of an underlying hemothorax or empyema and the usual delayed onset of chylothorax. Increased vigilance will allow physicians to properly diagnose and treat this condition early to avoid having to ligate the thoracic duct.

Successful treatment of primary pulmonary melanoma.

Presented is a rare case of a primary melanoma of the lung in an 89 year old male patient. Primary melanoma of the lung has been previously reported in the English literature in about 30 patients. Surgical resection either with lobectomy of pneumonectomy and a lymph node dissection has been shown to be the best chance of long term survival. This is the oldest patient on record where surgical resection was successful.

Intra-gastric band erosion from an un-inflated Lap-Band: a case report.

The increasing prevalence of morbid obesity is of public health concern throughout the world, and surgical intervention seems to offer the only long-term solution to the problem. Gastric banding is one of the available options in the bariatric armamentarium. As more Lap-Bands are being inserted, intragastric erosion is increasingly being encountered as a major complication. The case of a 40-year-old man with intra-gastric band erosion is presented with the band never having been inflated, suggesting that additional factors may play a role in the development of erosions. The presentation, diagnostic modalities, and pathognomomic findings are discussed.
