Large retroperitoneal lymphangioma.

Abnormal cystic lymphangioma is a rare, benign tumour of lymphatic origin that often presents with subtle clinical symptoms. A man in his 20s sought medical attention for a progressively tender mass located in the right lower quadrant. Following ultrasound and CT imaging, surgical pathology confirmed the presence of abnormal cystic lymphangioma. This case is noteworthy because of the patient's young age and the retroperitoneal location. An exploratory laparotomy was performed, mitigating the risk of recurrence. In the future, if imaging identifies a cystic mass, consideration of abnormal cystic lymphangioma within the differential diagnosis is imperative. Despite its predominantly subtle symptoms and non-malignant nature, the mass effect by the abnormal cystic lymphangioma can compromise surrounding structures. Overall, clinicians confronted with a cystic mass should adopt a comprehensive diagnostic approach, encompassing abnormal cystic lymphangioma in the differential diagnosis due to its unknown and complex nature.

An Ancillary Central Catheter Emergency Support Service Team Staffed by Surgical Personnel Improves Workflow During the Coronavirus Disease 2019 Crisis.

Background. The SARS-CoV-2 novel coronavirus disease 2019 (COVID-19) pandemic has posed significant challenges to urban health centers across the United States. Many hospitals are reallocating resources to best handle the influx of critical patients. Methods. At our New York City hospital, we developed the ancillary central catheter emergency support service (ACCESS), a team for dedicated central access staffed by surgical residents to assist in the care of critical COVID-19 patients. We conducted a retrospective review of all patients for whom the team was activated. Furthermore, we distributed a survey to the critical care department to assess their perceived time saved per patient. Results. The ACCESS team placed 104 invasive catheters over 10 days with a low complication rate of .96%. All critical care providers surveyed found the service useful and felt it saved at least 30 minutes of procedural time per patient, as patient to critical care provider ratios were increased from 12 patients to one provider to 44 patients to one provider. Conclusions. The ACCESS team has helped to effectively redistribute surgical staff, provide a learning experience for residents, and improve efficiency for the critical care team during this pandemic.

Anterior knee schwannoma.

Peripheral nerve tumors are relatively uncommon with schwannomas being the most common type. Schwannomas are usually benign encapsulated tumors composed of neoplastic Schwann cells that generally do not transform to malignancy. Many are discovered incidentally as solitary tumors. The cause is unknown. Most occur spontaneously, while some develop in association with genetic disorders such as neurofibromatosis type 2 or schwannomatosis. Schwannomas can occur anywhere in the body. They affect all ages, with peaking incidence between ages 20 and 50 years, without predilection to sex or race. Many are asymptomatic; however, presenting signs and symptoms, such as paresthesia and pain, are due to mass effect and direct nerve invasion. Diagnosing includes combinations of thorough physical examination, imaging modalities such as magnetic resonance imaging and surgical biopsy. Treatment depends on factors such as location of the tumor and severity of symptoms. Asymptomatic patients are treated conservatively while symptomatic patients undergo surgical resection with favorable prognosis.

Perforation of appendiceal adenocarcinoma ex goblet cell carcinoid: a rare case.

Goblet cell carcinoid tumor is a rare form of carcinoid tumor of the appendix. It behaves more aggressively than classical carcinoid tumor of the appendix. Thus, special attention must be given to its disease course and treatment. Our case presentation is of a 68-year-old female who presented with abdominal pain. Computed tomography of her abdomen and pelvis showed a perforated appendicitis. She underwent an ileocectomy with pathological report showing a goblet cell carcinoid tumor of the appendix with negative lymph nodes. A subsequent colonoscopy done 5 months later showed no synchronous lesions and a healthy anastomosis. Given the limited amount of data available about goblet cell carcinoid tumors of the appendix, it is important to report all findings in an effort to improve our understanding and treatment approaches of this rare disease.

A rare case of percutaneous endoscopic gastrostomy causing a small bowel obstruction and subsequent bowel erosion.

Gastrostomy tubes can be used to provide long-term nutrition and feeding when oral intake is not adequate. A rare but serious complication includes iatrogenic small bowel injury. The incidence of this is infrequent due to its position of the small bowel beneath the omentum, however, injury leading to obstruction and volvulus has been previously described in the literature. We present an unusual case of gastrostomy tube transection into omental fat causing a kink in the small bowel allowing for a transition point of obstruction and subsequent erosion of the gastrostomy tube into the small bowel.

Unusual complication of bladder prolapse with subsequent diagnosis of urothelial carcinoma leading to a necrotizing soft tissue infection after radical cystectomy.

There is lack of information in the literature on long-term complications of suprapubic catheters. The most common complications include urinary tract infection, bladder calculi, urine leakage and neoplastic changes. We report a case of an unusual complication of bladder prolapse, with subsequent diagnosis of urothelial carcinoma, leading to a necrotizing soft tissue infection after a radical cystectomy in a patient with long-term catheterization and its management. Due to the rarity of this complication, its management has not been well studied. In this particular case, the logical indication was radical cystectomy due to the presence of bladder necrosis.

Giant inflammatory polyposis, a phenomenon of inflammatory bowel disease, presenting as acute large bowel obstruction mimicking colonic neoplasm.

Inflammatory bowel disease (IBD) remains a topic of ongoing research given its prevalence, yet the pathogenesis and all clinical manifestations of the disease remain poorly understood. Giant inflammatory polyposis is one of the clinical manifestations of IBD that has rarely been described to the best of our knowledge. This is a recognized clinical entity, however, only a limited number of IBD associated cases have been described in literature to date. This phenomenon consists of numerous benign, inflammatory polyps that clump together giving the appearance of a larger mass, which may cause clinical colonic obstruction and radiographic findings mimicking colonic neoplasm. This clinical entity may present in 10-20% of patients with IBD.

Rhabdomyosarcoma masquerading as lymphadenopathy in a patient with newly diagnosed Hodgkin's lymphoma.

BACKGROUND: Hodgkin's lymphoma (HL) is a rare malignancy which often presents with lymphadenopathy and classic "B symptoms" of weight loss, fever, and night sweats. Additional masses or nodes could easily be presumed to be a result of the initial diagnosis. On the other hand, adult rhabdomyosarcoma is a rare malignancy presenting with a new mass in a patient with previous diagnosis of Hodgkin's lymphoma. In both cases, a tissue diagnosis should be obtained to appropriately confirm the diagnosis. CASE PRESENTATION: We present a case of a 64-year-old male who presents with right axillary lymphadenopathy, diagnosed as Hodgkin's lymphoma. He subsequently developed left inguinal lymphadenopathy without the classic B symptoms of HL. Excisional biopsy revealed rhabdomyosarcoma. Stage III Hodgkin's lymphoma (lymph node involvement on both sides of the diaphragm) is not commonly seen without typical B symptoms. Once the diagnosis of two primary malignancies is made, the dilemma becomes determining the treatment course. In the case of Hodgkin's lymphoma and rhabdomyosarcoma, there is some overlap in the chemotherapeutic regimen and use of radiation. CONCLUSIONS: This case illustrates the importance of careful examination of Hodgkin's lymphoma patients and consideration of additional tissue diagnoses in atypical presentations of new masses or lymphadenopathy on the opposite side of the diaphragm.

Metastatic prostate carcinoma mimicking primary anal cancer.

A 71-year-old man with a history of castration-refractory prostate cancer was initially treated with hormonal therapy. He responded with a decreasing prostate-specific antigen level and improved symptoms. Chemotherapy was initiated later, after an increasing prostate-specific antigen level and findings of distant metastases. Nine months after his initial diagnosis, he presented with a large multinodular perianal mass that was suspicious for primary anal cancer. Biopsy revealed poorly differentiated metastatic prostate carcinoma. The patient died 2 months after the initial presentation with perianal skin metastasis.
