: A Study of Near Obstructing Sigmoid Endometrioma.

A 41-year-old woman had a near-obstructing endometrioma involving the distal sigmoid colon treated with en bloc removal of the involved segment of colon and the adherent adnexa.

Endometrioma Causing Near-Complete Obstruction of the Sigmoid Colon.

Endometriosis is characterized by extra-uterine endometrial gland and stroma implantation. Intestinal endometriosis is believed to affect about one-third of patients with endometriosis; 72-95% of patients experience recto-sigmoid involvement. Occasionally, endometriotic lesions precipitate mass effect or infiltrate the bowel wall, mimicking a neoplasm.

Metastatic Primary Gastric Squamous Cell Carcinoma: An Uncommon Presentation of a Rare Malignancy.

Primary gastric squamous cell carcinoma is a very rare disease. A 53-year-old male with history of hypertension, alcoholism, and nicotine abuse presented to the hospital after a syncopal episode. He complained of bloating abdominal pain, early satiety, and poor appetite.

Diffuse Large B-Cell Lymphoma Mimicking an Ulcerative Colitis Flare.

We present a case of non-Hodgkin lymphoma of the rectum in a 41-year-old African American male with a 1 year history of ulcerative colitis and no previous immunomodulatory therapy. The patient presented with a 10-day history of hematochezia, for which endoscopy was performed with gross findings indicative of ulcerative colitis flare. Tissue biopsy, however, demonstrated significant lymphoid infiltrating regions with histologic findings suggestive of a diffuse large B-cell lymphoma.

Prospective evaluation of impact of using the Bethesda System for Reporting Thyroid Cytopathology: an institutional experience.

Introduction: The Bethesda System for Reporting Thyroid Cytology (BSRTC) refines the definition of and provides specific diagnostic criteria for fine-needle aspiration (FNA) assessment of thyroid lesions. This study was conducted to prospectively evaluate the diagnostic and clinical impact of using BSRTC for management of thyroid lesions and to compare diagnostic performance of post-BSRTC period with that of pre-BSRTC period.

Materials And Methods: The study included FNA specimens obtained in our institution 2.
