Challenges associated with low rectal malignant obstruction stenting: a case report.

An ongoing debate exists regarding the feasibility of placing self-expanding metallic stents (SEMS) within 5 cm of the anal verge. Traditionally, SEMS have been considered contraindicated for patients with a malignant rectal obstruction within this region due to potential impact on the anorectal ring or anal canal, which can cause incontinence, proctalgia, and tenesmus. However, in the case of a 63-year-old female who presented with distention, abdominal pain, and diminishing stool output, the rectal exam identified a bulky fixed mass.

Diffuse large B-cell lymphoma associated with papillary thyroid carcinoma: a case report and systematic review on management and outcomes.

Primary thyroid lymphoma is a rare thyroid cancer, comprising ˂5% of thyroid neoplasms. Most cases are diffuse large B-cell lymphoma (DLBCL). Coexistence with papillary thyroid cancer (PTC) is extremely rare.

Laparoscopic Repair of a Congenital Diaphragmatic Hernia Presenting with a Small Bowel Obstruction.

Diaphragmatic hernias are uncommon, and can appear secondary to trauma or as a congenital defect. These hernias can be asymptomatic or have various clinical presentations. One of the clinical scenarios is incarceration of bowel through the diaphragmatic defect.

Zuska's breast disease: Breast imaging findings and histopathologic overview.

Zuska's disease describes the clinical condition of recurrent central or periareolar nonpuerperal abscesses associated with lactiferous fistulas. Pathogenesis involves the occlusion of an abnormal duct through an epithelial desquamation process that causes ductal dilatation, stasis of secretions, and periductal inflammation. Patients with Zuska's disease may develop chronic draining sinuses near the areola from lactiferous ducts fistula; therefore, the underlying abnormal duct system must be located and excised for proper treatment.

Contrast media in breast imaging.

Although mammography is the standard imaging modality for detection of breast cancer, magnetic resonance (MR) imaging is a valuable adjunct and, in certain cases, is the imaging of choice. Contrast-enhanced breast MR imaging provides a noninvasive means of staging disease, assessing posttreatment response, and screening of high-risk patients with genetic predispositions. Additional indications for MR mammography include lesion characterization, contralateral breast evaluation in patients with proved malignancy, and identifying primary malignancy in patients with axillary nodal disease.
