Anaplastic oligoastrocytoma with dual genotype: A case report of a rare entity

Splenic abscess is a rare entity, however if unrecognised or left untreated, it is invariably fatal. We herein report a case of splenic abscess in a 40-year-old man presenting with fever, left-sided abdominal pain, altered sensorium and vomiting. On clinical examination, hepatosplenomegaly was noted and the ultrasound of the abdomen showed multiple hypoechoic regions in the upper pole of spleen, and the diagnosis of splenic abscess was made. The patient received antimicrobial therapy and underwent an open splenectomy with full recovery. Pus aspirated from the splenic abscess grew an unusual organism named Parabacteroides distasonis. In the literature, there are only a few recorded cases of P. distasonis causing splenic abscess. Through this case report, we would like to emphasise the pathogenic role of P. distasonis in causing clinical disease, as this organism is typically known to constitute a part of the normal flora.

Abstract Background Mantle cell lymphoma (MCL) is an aggressive subtype of B-cell non-Hodgkin lymphoma (NHL), often diagnosed at later stages with secondary gastrointestinal (GI) involvement. Primary GI MCL is rare and is not often discussed in the literature. Aims To increase awareness of a rare condition that is likely to be encountered but can be challenging to diagnose. Methods Case report and review of the literature. Results Case Report A 78-year-old man with multiple untreated vascular risk factors including atrial fibrillation and type 2 diabetes presented with acute onset left hemiplegia, dysarthria, and imaging consistent with a left pontine stroke. As part of his workup he underwent a CT abdomen/pelvis identifying an 11 x 5 cm intraluminal mass in the transverse colon. Previous screening colonoscopies, for family history of colon cancer, were notable for tubular adenomas without high-grade dysplasia at 13, 12, 10, 7, and 2 years prior to admission. The patient had 16 pounds of weight loss without other constitutional symptoms, change in bowel habits or evidence of GI bleeding. Bloodwork was notable for microcytic anemia (Hemoglobin 91 g/L, MCV 75 fL), from a normal baseline one year prior, without other cytopenias. C-reactive protein (44 mg/L) and GGT (164 U/L) were elevated. Other liver enzymes, lactate dehydrogenase, and electrolytes were normal. Colonoscopy revealed numerous polypoid lesions throughout the entire colon and a large non-obstructive mass with submucosal appearance in the transverse colon. Biopsies were taken from the large mass and one of the smaller polypoid lesions. Histology showed a sheet-like infiltrate of small lymphocytes within the lamina propria. Immunohistochemical staining was positive for CD20, BCL2, Cyclin D1, equivocal for CD5, and negative for BCL6 and CD3. Ki67 index approached 30%. A diagnosis of colonic MCL was made. Literature Review Primary MCL of the GI tract is rare, accounting for only 1 to 4% of all GI malignancies. There is a male and Caucasian predominance with a median age of 68 years at diagnosis. Presenting complaints may include abdominal pain, anorexia, and GI bleeding. Typical endoscopic features are small nodular or polypoid tumors, between 2mm and 2 cm in size, along one or more segments of the GI tract referred to as multiple lymphomatous polyposis (MLP). A single colonic mass is infrequently seen, highlighting the importance of endoscopy for diagnosis, as subtle findings may be missed on radiographic evaluation. Biopsies for immunohistochemistry are essential to distinguish MCL from other NHLs, as almost all cases express cyclin D1. Despite aggressive immunochemotherapy, prognosis is often poor due to MCL’s rapid progression and early relapse. Conclusions Primary GI MCL is a rare entity. Awareness is essential as evaluation and management differ from lymphoma at other sites, and other GI malignancies. Funding Agencies None

Pathologic Fractures

Abstract Gorham-Stout disease (GSD) is a rare entity that destroys the bone matrix resulting mainly in osteolysis, pain and pathologic fractures among a broader clinical picture. We report a case of a 60-year-old female with a sudden discovery of pathologic fractures in the pelvis and the absence of the left femoral head. On biopsy, no cellular atypia was found, instead disturbed bone formation with prominent vascularity with scattered foci of necrosis & osteolysis, which lead to the diagnosis of GSD. Possible differential diagnoses were discussed and excluded. The patient was put on Bisphosphonate that led to a relative improvement in the symptoms. This disease needs a more thorough investigation to identify the key cause, what is beyond the scope of this report.

Abstract Background Scrotoschisis is a rare anomaly in which the testis is lying outside scrotum congenitally. Only few cases have been reported in literature under different names most of which are unilateral. We have found only one case of bilateral scrotoschisis in literature. Case presentation Newborn presented to us after normal term twin delivery as a case of bilateral scrotoschisis in which both testes were lying outside the scrotum congenitally. Baby underwent uneventful bilateral orchiopexy and was discharged home the next day. Conclusion Scrotoschisis is a very rare genital anomaly with only a few cases reported in literature. This report would add to the literature which would help in studying the exact mechanism and embryopathogenesis of this anomaly which is not known yet.
