Pyogenic granuloma of the terminal ileum diagnosed by colonoscopy: the relevance of ileocecal valve intubation.

Pyogenic granuloma is a benign vascular lesion that is most frequently found in the epidermis or mucosa of the oral cavity. Its finding in the ileum is rare, there are only a few case reports. In most reported cases, diagnosis is made with capsule endoscopy or double-balloon enteroscopy. We present a case of a lesion in the ileum, approximately 15 cm from the ileocecal valve, documented by colonoscopy.

Endoscopic stent placement after spontaneous esophageal perforation associated with chemoradiotherapy for esophageal cancer.

A 38-year-old male with established diagnosis of stage IV squamous cell carcinoma of the esophagus treated with chemoradiotherapy (25 sessions of 50 Gy), presented with acute aphagia, thoracic pain, productive cough, and mild hemoptysis. Upon physical examination the right hemithorax presented with crepitations. An initial CT scan showed an esophageal perforation. An upper endoscopy was performed, visualizing the esophageal perforation in the mid third of the esophagus at 26 cm of the dental arcade. It was possible to bypass and intubate the stomach, enabling the placement of a guide wire under endoscopic visualization. Afterwards, a partially covered, self-expandable, metal stent (Wallflex esophageal stent 10 cm/18/23; Boston Scientific) was placed in the esophagus restoring continuity, visualized by fluoroscopy.

Acute Leukemia Characteristics are Different Around the World: the Mexican Perspective.

BACKGROUND: The incidence of acute leukemia (AL) has increased. Its prognosis is variable and depends on several baseline characteristics with a highly heterogeneous presentation. In Mexico, large-scale descriptive studies have not yet been published; the objective of this study was to analyze the initial basic characteristics of patients diagnosed with AL in our population. PATIENTS AND METHODS: In this multicenter, retrospective study, 1018 patients ≥ 16 years of age and diagnosed with AL between 2009 and 2014, were included. We described age, gender, complete blood count, and AL subtype according to flow cytometry analysis. RESULTS: Acute lymphoblastic leukemia (ALL) was as common as acute myeloid leukemia (AML) (51% vs. 49%). The median age was 31 years. Only 9.6% of patients with ALL were positive for the Philadelphia chromosome. No gender differences were observed. The median age at presentation of AML was 43 years. Acute promyelocytic leukemia was the most frequent AML subtype (38.3%), with a median age of 37 years. CONCLUSION: ALL is equally as frequent as AML in patients ≥16 years of age. Philadelphia-positive prevalence is less frequent than that reported in literature. AML cases occur in a younger age in comparison with other countries. There is a higher rate of acute promyelocytic leukemia among our patients compared with other non-Latin American populations. This study is the largest ever performed in Mexico regarding descriptive AL data.
