Primary hepatic leiomyosarcoma is exceedingly rare accounting for less than 1% of the hepatic tumors. Close to 45 cases have been reported in the English literature. Presentation is usually nonspecific and diagnosis is often delayed until tumors reach a large size. This leads to a dismal prognosis. The tumors are not yet fully understood, hence the standard of care is not well defined. Curative resection remains the mainstay of management. Close association of Epstein Barr virus (EBV) induced soft tissue sarcomas is proven, especially in the presence of immunosuppression encountered in HIV/AIDS patients and in posttransplant patients. We herein present a case report of a 54-year-old man diagnosed to have HIV/AIDS and EBV infection admitted to our hospital with complaints of intractable hiccups for more than a week. Extensive workup revealed primary leiomyosarcoma of the liver.
Coronavirus disease 2019 (COVID-19) predominantly presents with respiratory symptoms, however, the involvement of the gastrointestinal system has also been reported. Isolated gastrointestinal manifestation due to COVID-19 presenting as colonic distension is uncommon. Colonic ileus from COVID-19 infection presents as dilatation on imaging, with the risk of subsequent ischemia and perforation if not recognized and treated promptly. There is no consensus on the treatment modality for COVID-19-related colitis, however, COVID-19-targeted medications in conjunction with surgical intervention have been performed for management. We present a case of a 73-year-old man who presented with abdominal pain, distention, and diarrhea. He tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and was found to have marked dilatation of the colon on imaging. He was initially given convalescent plasma to reduce inflammatory markers, as tocilizumab was contraindicated due to suspected bowel obstruction. Once more stable, he underwent surgical intervention followed by tocilizumab infusion. Pathological specimens of the colon demonstrated hemorrhagic colitis with microthrombi suggestive of COVID-19-related colitis. Recognizing COVID-19-related colitis allows for timely diagnosis and management with targeted interventions in addition to surgery, which may prevent perforation. We suggest convalescent plasma followed by the formation of colostomy and finally infusion of tocilizumab as a feasible option for the treatment of COVID-19-related colitis. However, further research is needed in order to fully understand this entity and provide guidance for its management.
We report this case of secondary amyloidosis associated with Castleman's disease. A 51-year-old man presented with systemic symptoms of generalized weakness, fatigue, unintended weight loss, anorexia and progressively worsening abdominal distension. On examination he was found to have an indurated right-sided submandibular mass and tense ascites. He was found to have multiorgan dysfunction with deranged liver function tests and renal failure. Ascitic fluid analysis revealed evidence of spontaneous bacterial peritonitis. Biopsy of the submandibular mass revealed angiofollicular lymph node hyperplasia consistent with a diagnosis of Castleman's disease. A subsequent liver biopsy showed extensive deposition of amyloid protein. Bone marrow biopsy also showed the presence of amyloid and increased kappa light chain-restricted plasma cells. The patient was not considered a candidate for chemotherapy or solid organ transplantation in view of active sepsis and poor physical condition. Secondary systemic amyloidosis complicating Castleman's disease is very rare. Untreated secondary systemic amyloidosis often has a rapidly fatal course, such as seen in our patient.
BackgroundDiabetic ketoacidosis (DKA) is a common acute complication of diabetes mellitus requiring aggressive medical management. We attempted to study the incidence and various clinical and laboratory variables associated with acute gastrointestinal bleeding (AGIB) and acute upper AGIB (AUGIB) in patients with DKA.MethodsWe conducted a retrospective chart review of all the patients admitted to our hospital with DKA between January 2010 and December 2015. We collected demographic, clinical, laboratory, endoscopy and hospitalization details using an electronic medical-record database. Patients were divided into two groups based on the occurrence of gastrointestinal bleeding.ResultsA total of 234 patients with DKA were admitted during this period, of which 27 (11.5%) patients had documented AGIB. The majority of patients had hematemesis (n=22, 9.4%) except two had rectal and three had occult bleeding. We did not notice any difference in age, gender and ethnicity distribution between the two groups. There was no difference in the serum levels of electrolytes, anion gap, pH and hemoglobin A1C between the two groups. However, patients with AGIB had significantly higher initial blood glucose levels (738 vs 613 mg/dL, p =0.014). There was also increased mortality (7.4% vs 4.8%) in patients with AGIB, but this did not reach statistical significance.ConclusionWe conclude that higher initial serum blood glucose was associated with increased incidence of AGIB in patients admitted with DKA. We also noted increased in-patient mortality in patients with DKA who had AGIB, even though statistically insignificant. More aggressive measures to correct blood glucose levels may result in decreased incidence of AGIB, thereby reducing mortality during hospitalization in patients with DKA.
Adenocarcinoma of the lung infrequently metastasizes to the gastrointestinal tract. We report a rare case of a 65-year-old male with no respiratory symptoms diagnosed with adenocarcinoma of the lung by histopathological examination of metastatic sites which included an ulcer in the gastric body and a mass in the rectum. Metastatic disease also involved the liver as well. Patient was treated with systemic chemotherapy but unfortunately expired five months after the diagnosis was made.
Cystic lymphangiomas are benign colonic neoplasms arising from the submucosa. Traditionally, endoscopic resection has been described for smaller lesions, while surgery is reserved for larger symptomatic lesions. We present a case of a 69-year-old asymptomatic individual noted to have a cystic lymphangioma of the colon measuring 5 cm, which was successfully removed with endoloop endoscopic resection without any complications.
Endometriosis is a common gynecological condition wherein there is an ectopic implantation of the uterine endometrial tissue. While several diagnostic modalities are described for the condition, laparoscopy remains the gold standard. There is still an undiscovered area to diagnose colonic endometriosis at an earlier stage. We present a case report of a reproductive age woman with cyclical rectal bleeding diagnosed with colonic endometriosis with colonoscopy and biopsy using saline injection lift and sampling technique. We in our report try to impress the fact that this differential should always be considered in the appropriate clinical setting, especially in women of childbearing age and in such cases, deeper tissue sampling techniques should be sought for, given better diagnostic yield. This may be clinically important given that it may aid in earlier diagnosis and thereby early initiation of appropriate therapy before the disease takes a complicated route. It may also be helpful in avoiding unnecessary surgery, along with the morbidity, complications and costs associated with same.
We report this case of a 42-year-old woman who presented with a debilitating illness manifested by intractable nausea, vomiting, diarrhea and unchecked weight loss. The patient had multisystem involvement that presented as anemia, abnormal liver function tests and progressively deteriorating renal function necessitating dialysis. She was found to be profoundly hypoalbuminemic secondary to malabsorptive and protein-losing enteropathy in tandem with nephrotic range proteinuria. Intolerance to enteral feeding led the patient to be dependent on parenteral nutrition. Serum immunofixation revealed IgG lambda monoclonal protein. The patient underwent endoscopic evaluation with biopsies taken from the gastrointestinal tract that confirmed the diagnosis of primary systemic light-chain amyloidosis. A subsequent bone marrow biopsy revealed normocellular bone marrow with deposition of amyloid. The patient was not considered for autologous stem cell transplantation as the outcomes in patients with multisystem involvement are often poor, with a high mortality risk. Diffuse primary systemic light-chain amyloidosis involving the gastrointestinal tract is a rare entity and is to be considered among differentials in patients presenting with unexplained malabsorptive symptoms.
