The genomic landscape of transformed splenic diffuse red pulp small B-cell lymphoma.

The genetic landscape underlying the transformation of splenic diffuse red pulp small B-cell lymphoma (SDRPL) is not well understood. The present study aimed to unravel the genomic alterations involved in the progression and transformation of SDRPL. We performed genetic studies on both SDRPL and subsequent or synchronous diffuse large B cell lymphoma (DLBCL) samples in three SDRPL patients who eventually developed DLBCL.

Large B-cell lymphomas with CCND1 rearrangement have different immunoglobulin gene breakpoints and genomic profile than mantle cell lymphoma.

Mantle cell lymphoma (MCL) is genetically characterized by the IG::CCND1 translocation mediated by an aberrant V(D)J rearrangement. CCND1 translocations and overexpression have been identified in occasional aggressive B-cell lymphomas with unusual features for MCL. The mechanism generating CCND1 rearrangements in these tumors and their genomic profile are not known.

Characterization of Ovarian Granulosa Cell Tumors using Magnetic Resonance Imaging.

Purpose: To identify the MRI features that aid in the characterization of ovarian granulosa cell tumors.

Materials And Methods: 11 MR pelvis of an adult woman with pathology-proven ovarian granulosa cell tumors with surgical pathology.We evaluated the patient's age, Ca-125, size, laterality, and with MRI features such as indirect signs (i.

Early pancreatic cancer in IgG4-related pancreatic mass: A case report.

Background: IgG4-related disease can manifest diversely, including autoimmune pancreatitis and IgG4-related cholangiopathy. We are reporting a very unusual cause of pancreatic cancer triggered in a previously unknown IgG4-related disease.

Case Summary: A 75-year-old man was diagnosed with a 43 mm × 33 mm pancreatic head tumor after consulting for abdominal pain and jaundice.

Syringocystadenocarcinoma papilliferum with orbital invasion: a case report with literature review.

We present a case of Syringocystadenocarcinoma papilliferum that originated in the eyelid and extended into the orbit. These tumors are very rare and have the potential to metastasize. A literature review of all the previous cases has been compiled from the Medline, EMBASE, and PubMed databases.
