Surg Laparosc Endosc Percutan Tech 2018 Dec 3. Epub 2018 Dec 3.

Department of Surgery, University Hospital of Pontevedra, Pontevedra, Spain.

Aim: The aim of this study was to evaluate the results of laparoscopic cholecystectomy (LC) in patients with xanthogranulomatous cholecystitis (XGC) compared with patients without XGC.

Methods: A retrospective study was performed including patients who had undergone elective LC between January 2003 and November 2017. Results of patients with XGC (25) were compared with those of patients without XGC (2181) with respect to operative time, conversion rate, drain use, postoperative complications, and postoperative stay.

Xanthogranulomatous reaction to trametinib for metastatic malignant melanoma.

Cutis 2018 Oct;102(4):283-286

Department of Dermatology, Icahn School of Medicine at Mount Sinai, New York, New York, USA.

Trametinib, a mitogen-activated extracellular signal-regulated kinase (MEK) inhibitor, has demonstrated great promise in treating metastatic melanoma associated with BRAF V600E and V600K mutations; however, it also is highly associated with cutaneous adverse events (AEs). As both BRAF and MEK inhibitors become increasingly used to treat malignant melanoma, it is important to better characterize these AEs so that we can manage them. Herein, we present a case of a 66-year-old man who developed erythematous scaly papules on the face and bilateral upper extremities after beginning therapy with trametinib. Read More

Comet tail artifact on ultrasonography: is it a reliable finding of benign gallbladder diseases?

Ultrasonography 2018 Oct 3. Epub 2018 Oct 3.

Department of Radiology, Eulji University Hospital, Daejeon, Korea.

Purpose: The aim of this study was to evaluate whether the comet tail artifact on ultrasonography can be used to reliably diagnose benign gallbladder diseases.

Ancillary studies in fine needle aspiration of the kidney.

Cancer Cytopathol 2018 Aug;126 Suppl 8:711-723

Baptist Hospital of Miami and Miami Cancer Institute, Miami, Florida.

An increasing number of renal cell carcinomas (RCCs) require ancillary studies for diagnosis. The majority of renal fine needle aspirates do not require ancillary studies.

Pyeloduodenal Fistula in Xanthogranulomatous Pyelonephritis: A Series of Two Cases.

Perm J 2018 06;22

Surgeon in the Division of Transplant Surgery and the Division of Acute Care Surgery and Trauma at Memorial Regional Hospital in Hollywood, FL.

Xanthogranulomatous inflammation, characterized by destruction and replacement of tissues with chronic inflammatory cells, including foamy histiocytes and hemosiderin-laden macrophages, is uncommon. In patients with xanthogranulomatous pyelonephritis, inflammation may extend from the kidney to the overlying duodenum, creating a pyeloduodenal fistula that further complicates medical and surgical management. We present two cases with recurrent kidney infections who each ultimately received a nephrectomy and repair of their duodenal fistula. Read More

From the Department of Radiology, Virginia Commonwealth University Medical Center, 1250 E Marshall St, PO Box 980615, Richmond, VA 23298.

A variety of entities may mimic drainable abscesses. This can lead to misdiagnosis of these entities, unnecessary percutaneous placement of a pigtail drainage catheter, other complications, and delay in appropriate treatment of the patient. Types of entities that may mimic drainable abscesses include neoplasms (lymphoma, gallbladder cancer, gastrointestinal stromal tumor, ovarian cancer, mesenteric fibromatosis, ruptured mature cystic teratoma, recurrent malignancy in a surgical bed), ischemia/infarction (liquefactive infarction of the spleen, infarcted splenule), diverticula (calyceal, Meckel, and giant colonic diverticula), and congenital variants (obstructed duplicated collecting system).

Urinary tract infection (UTI) is one of the most common presentations in general practice and, in most instances, occurs in a single episode and is easily treated with a course of anti-microbial therapy. In the case of recurrent urinary tract infections, it is important to consider evaluation for any underlying causes. We report the case of a 32 year old female who had recurrent UTIs; this was a case of recurrent UTI secondary to xanthogranulomatous pyelonephritis from renal stones with resultant reno-colic fistula formation.
