Ectopic pancreas at the ampulla of Vater diagnosed with endoscopic snare papillectomy: A case report and review of literature

BACKGROUND Ectopic pancreas is a rare developmental anomaly that results in a variety of clinical presentations.Patients with ectopic pancreas are mostly asymptomatic,and if symptomatic,symptoms are usually nonspecific and determined by the location of the lesion and the various complications arising from it.Ectopic pancreas at the ampulla of Vater(EPAV)is rare and typically diagnosed after highly morbid surgical procedures such as pancreaticoduodenectomy or ampullectomy.To our knowledge,we report the first case of confirmed EPAV with a minimally invasive intervention.CASE SUMMARY A 71-year-old male with coronary artery disease,presented to us with new-onset dyspepsia with imaging studies revealing a‘double duct sign’secondary to a small subepithelial ampullary lesion.His hematological and biochemical investigations were normal.His age,comorbidity,poor diagnostic accuracy of endoscopy,biopsies and imaging techniques for subepithelial ampullary lesions,and suspicion of malignancy made us acquire histological diagnosis before morbid surgical intervention.We performed balloon-catheter-assisted endoscopic snare papillectomy which aided us to achieve en bloc resection of the ampulla for histopathological diagnosis and staging.The patient’s post-procedure recovery was uneventful.The en bloc resected specimen revealed ectopic pancreatic tissue in the ampullary region.Thus,the benign histopathology avoided morbid surgical intervention in our patient.At 15 mo follow-up,the patient is asymptomatic.CONCLUSION EPAV is rare and remains challenging to diagnose.This rare entity should be included in the differential diagnosis of subepithelial ampullary lesions.Endoscopic en bloc resection of the papilla may play a vital role as a diagnostic and therapeutic option for preoperative histological diagnosis and staging to avoid morbid surgical procedures.

CD34-Negative B-Lymphoblastic Leukemia/Lymphoma Presenting as Cutenous Lesions at Infancy: A Case Report

Acute lymphoblastic leukemia/lymphoma is a highly aggressive neoplasm of precursor lymphoid (blast) cells. There are 2 main subtypes based on lymphoid lineage;B lymphoblastic leukemia/lymphoma (B-ALL/LBL) and T lymphoblastic leukemia/lymphoma (T-ALL/LBL). B-ALL/LBL commonly presents with fever, fatigue, bone or joint pain, bleeding or anorexia (signs of bone marrow infiltration), lymphadenopathy, hepatosplenomegaly, involvement of skin, soft tissue and testes, with a predilection for the central nervous system. Immature cell markers, such as CD34 and TdT, can help to differentiate lymphoblasts from Burkitt lymphoma which, is considered a mature high-grade B cell lymphoma that mimics lymphoblastic lymphoma/leukemia. Unfavorable prognostic factors include: infancy and adult age of diagnosis, high white blood cell count, slow response to initial therapy, central nervous system involvement at the time of diagnosis and Minimal residual disease after therapy. We present a case report of a 4 months old infant seen at a Tertiary Hospital with a rare presentation of CD34 Negative B-lymphoblastic leukemia/lymphoma presenting as cutaneous lesions in infancy.
