Case Report: Successful R0 resection in locally advanced retroperitoneal sarcomas.

We present a case series of three successfully resected tumors in our center at Al-Makassed Hospital in Jerusalem, Palestine, all of which primarily involved or invaded adjacent structures and needed a multidisciplinary approach to achieve R0 resection. Our first patient is a 42-year-old previously healthy female with intermittent attacks of dull aching abdominal pain. Her tumor was a leiomyosarcoma that involved major vessels and other adjacent vital structures. Ultimately, she needed major highly advanced surgery necessitating the need for vascular reconstruction of the IVC, as well as R0 resection. The surgery was performed by a multidisciplinary team of highly specialized surgeons in related fields. Our second case is a 75-year-old female patient with a well-differentiated liposarcoma invading the upper pole of the right kidney, necessitating a nephrectomy. Consequently, this case demanded the interdisciplinary involvement of nephrology. Our third patient is a 59-year-old male with dedifferentiated liposarcoma that involved the spleen, pancreas, and splenic flexure while engulfing the left kidney and ureter. Beyond the removal of the tumor, multiorgan resection was imperative to achieve microscopic margin-free resection. This extensive local spread needed broad collaboration from the medical team and other surgical subspecialties. All surgeries went well, and their outcomes were promising. All patients had an uneventful follow-up and, to date, no recurrence. Invasive retroperitoneal sarcomas of different histological types and clinical stages represent a technical challenge. Careful preoperative investigation and an experienced, dedicated multidisciplinary team of surgeons and non-surgeons from related fields, including vascular, urologic, and hepatobiliary surgeons, are usually needed for a safe and successful R0 resection despite extensive tumor involvement in light of difficulty achieving early diagnosis.

Gray Platelet Syndrome-Unusual Presentation with Spontaneous Splenic Rupture: A Case Report and Literature Review.

Gray platelet syndrome (GPS) is a rare hereditary hemorrhagic disorder characterized by macrothrombocytopenia and the absence of alpha-granules in platelets. Clinically, mild-to-moderate bleeding is the main manifestation, often accompanied by thrombocytopenia, splenomegaly, and myelofibrosis. Here, we present a case of a 15-year-old male patient with a history of hepatosplenomegaly, and thrombocytopenia for 8 years, who presented with sudden generalized abdominal pain. Despite initial suspicion of gastroenteritis, diagnostic imaging revealed an extensive hemoperitoneum. Subsequent genetic testing confirmed the diagnosis of GPS, which had not been previously identified. This case highlights the importance of considering inherited platelet disorders should be considered in adolescents with long-standing thrombocytopenia, and emphasizes the need for thorough evaluation in patients with suggestive symptoms.

Unveiling follicular thyroid carcinoma by solitary spinal metastasis causing severe neurological deficit in a 67-year-old female: A case report.

INTRODUCTION AND IMPORTANCE: Follicular thyroid carcinoma (FTC) exhibits the ability to metastasize hematogenously to distant organs. Spinal metastasis is an unusual site for metastasis that even when it does, spinal metastasis manifests late in the course of the disease and is frequently linked to advanced disease and a bad prognosis. Until 2019, the literature only showed 29 cases of FTC with spinal metastasis as the first presenting feature. CASE PRESENTATION: We present a case of a 67-year-old female who presented with an acute onset of severe neurological deficit that ended up bedridden. Magnetic resonance imaging of the spine revealed a spinal lesion causing severe spinal cord compression. Urgent surgical decompression was performed, and the histopathology confirmed metastatic FTC. Subsequent comprehensive evaluation, unveiled a primary thyroid tumor. CLINICAL DISCUSSION: FTC accounts for 1 % of all malignancies, Therefore, regardless of how irrelevant symptoms may appear at first, it is important to understand all risk factors, screening recommendations, diagnostic techniques, treatment, and the vast range of potential presenting symptoms. Just like our patient, who had incontinence and abrupt loss of motor and sensory function in her lower limbs to be diagnosed with spinal cord compression by metastatic FTC. CONCLUSION: This instance emphasizes how crucial it is to consider FTC as a possible differential diagnosis in cases with spinal metastasis, even when there is no known primary thyroid cancer. Prompt diagnosis, comprehensive staging, and multidisciplinary management are crucial in optimizing outcomes.

Inferior mesenteric arteriovenous malformation extending to splenic flexure colonic wall presenting with massive lower gastrointestinal bleeding, a case report.

INTRODUCTION AND IMPORTANCE: An arteriovenous malformation (AVM) in the inferior mesenteric artery is a rare vascular pathology that accounts for 6 % of the causes of gastrointestinal bleeding. AVMs are typically classified as congenital persisting embryonic vasculature that link both systems and do not develop into arteries or veins [3], but they may also develop later in life. The majority of documented cases are iatrogenic after colon surgery. CASE PRESENTATION: Herein we describe a 56-year-old man who presented complaining of fresh blood per rectum with passage of clots not related to defecation with no previous similar episodes, he was found to have extensive inferior mesenteric branches AVM invading the colonic splenic flexure via Computed Tomography (CT) angiography following three non-revealing upper and lower endoscopies which was later managed surgically with left hemicolectomy with primary end to end colo-colic anastomosis. CLINICAL DISCUSSION: Although AVMs seldom manifest in multiple sites through the gastrointestinal tract, it is more prevalent in the stomach, small intestine, and ascending colon, and very unusual to affect the Inferior mesenteric artery and vein and to extend to the splenic flexure colonic wall. CONCLUSION: Even if rare, inferior mesenteric AVMs should be suspected in a patient presenting with GI Bleeding with unrevealing endoscopies, where CT Angiography is to be considered.

Pancreatic duplication cyst misdiagnosed as distal pancreatic tumor: A case report and surgical approach.

Enteric duplication cysts (EDCs) are a benign and uncommon congenital malformation, with a nonspecific and extremely variable clinical presentation. EDCs associated with the pancreas are called pancreatic duplication cysts (PDCs). They are especially rare and can present with recurrent abdominal pain or even severe pancreatitis. These cysts often get confused with pancreatic neoplasms or pseudocysts, thus posing diagnostic and surgical challenges. Here, we report a case of a 20-year-old male patient with a 14-year history of recurrent abdominal pain and many hospital admissions, who had several imaging studies revealing a persistent focal heterogeneous lesion affecting the tail of the pancreas, surrounding a small pseudocyst. An ultrasound (U/S) guided biopsy was avoided due to the location of the mass. Surgical resection was carried out for the suspicion of malignancy and final pathology report showed benign findings while revealing that what was thought to be a pseudocyst turned out to be a gastric-type PDC, and after reviewing the available literature, we encountered 16 similar cases regarding misdiagnosing PDCs. We conclude that PDCs are very rare and have a variable clinical presentation as well as a likelihood of being confused with other pancreatic neoplasms. Therefore, PDCs need a high index of suspicion to avoid recurrent hospital admissions and unnecessary procedures due to the fact that sometimes a simple cystectomy is adequate.

Resection of Primary Renal Leiomyosarcoma Involving the Inferior Vena Cava (IVC) with IVC Resection and Reconstruction.

Renal leiomyosarcoma is a rare, aggressive tumor of the smooth muscles of the kidney. In our case, the tumor has special characteristics that made it highly challenging, as it involved major vessels and other adjacent vital structures. The rarity of the tumor type itself and the special challenging features we faced intraoperatively encouraged us to report the case including the management plan for R0 resection. Our patient is a forty-two years old previously healthy female, with vague nonspecific presenting complains, ended up with a major highly advanced surgery necessitating the need for vascular reconstruction of IVC. The surgery was performed by a multidisciplinary team of highly specialized surgeons in related fields. The surgery went well, and the outcome was promising. The patient was followed up for about four months later, with uneventful course.
