Chondromyxoid Fibroma of the Pelvis: Institutional Case Series With a Focus on Distinctive Features.

Int J Surg Pathol 2018 Dec 23:1066896918820446. Epub 2018 Dec 23.

1 Johns Hopkins University, Baltimore, MD, USA.

Chondromyxoid fibroma (CMF) is a relatively uncommon benign bone tumor of cartilaginous differentiation. The primary pitfall in the histopathologic diagnosis of CMF is confusion with a high-grade chondrosarcoma, owing to the atypical stellate and spindled cells set within a chondromyxoid background. CMF is particularly challenging to diagnose within the pelvis, where clinical suspicion for chondrosarcoma is high and benign lesions may grow to a large size to occupy the pelvic bones. Read More

Pitfalls of Frozen Section in Gynecological Pathology: A Case of Ovarian Serous Surface Papillary Adenofibroma Imitating Malignancy.

Int J Surg Pathol 2018 Dec 18:1066896918818894. Epub 2018 Dec 18.

1 Rutgers-New Jersey Medical School, Newark, NJ, USA.

Serous cystadenofibromas are uncommon benign ovarian lesions, consisting of both fibrous and epithelial components, that are usually cystic but may contain solid or papillary architecture that can be confused with a malignancy on imaging. Papillary architecture seen on frozen section may also falsely steer the pathologist in the direction of a diagnosis of a borderline serous tumor. Overcalling the lesion may lead to more aggressive surgery than necessary, so extensive tissue sampling and consideration of this entity is important in possibly avoiding this mistake. Read More

Collagenous Spherulosis in Well-Differentiated Papillary Mesothelioma in a Female With Multilocular Peritoneal Inclusion Cysts.

Int J Surg Pathol 2018 Dec 6:1066896918816815. Epub 2018 Dec 6.

1 Rashid Hospital, Dubai, UAE.

Multilocular peritoneal inclusion cysts are mesothelial tumor-like lesions with or without small foci of florid papillary mesothelial hyperplasia that might simulate serous epithelial papillary lesions or well-differentiated papillary mesothelioma (WDPM) of the peritoneum. The papillary cores in papillary mesothelial hyperplasia and in WDPM display a variety of different histomorphologic features. To our knowledge, collagenous spherulosis in WDPM was not previously described or illustrated in the literature. Read More

Morphological and Immunohistochemical Biomarkers in Distinguishing Prostate Carcinoma and Urothelial Carcinoma: A Comprehensive Review.

Int J Surg Pathol 2018 Dec 3:1066896918814198. Epub 2018 Dec 3.

1 University Hospital, Foggia, Italy.

The differential diagnosis between high-grade prostate carcinoma and infiltrating urothelial carcinoma (UC) in transurethral resection prostate specimens as well as cystoprostatectomy specimens may often be challenging due to morphologic and clinical overlap of the 2 entities. Such distinction has critical therapeutic and staging consequences, yet it is hampered by both issues in morphology and by the low accuracy rates of single immunohistochemical markers, as reported in literature. This review aims to provide a comprehensive analysis of the available morphological and immunohistochemical parameters, which may allow to discriminate between prostate carcinoma and urothelial carcinoma in the proper clinical context and to discuss their diagnostic applications in daily practice.

Coryneform Bacteria in Granulomatous Lobular Mastitis: Morphological Diagnosis in Breast Biopsies.

Int J Surg Pathol 2018 Nov 29:1066896918815580. Epub 2018 Nov 29.

1 Pontificia Universidad Católica de Chile, Santiago, Chile.

Granulomatous lobular mastitis is a rare disease whose origin is still unknown and shows an increase in its frequency. Morphological, microbiological, and molecular biology studies have linked this disease to lipophilic and fastidious corynebacteria, suggesting its possible infectious etiology. This series describes and reviews in detail the distinctive morphological characteristics of the bacteria present in the granulomas of this disease, the usefulness of histochemical techniques for their identification, and our proposal for a tissue quantification score for the bacteria.

Diffuse Large B-Cell Lymphoma With Striking Intrasinusoidal Pseudoglandular Growth Pattern as a Diagnostic Dilemma Mimicking Metastatic Poorly Differentiated Pancreatic Adenocarcinoma in an Intraabdominal Lymph Node.

Int J Surg Pathol 2018 Nov 4:1066896918810866. Epub 2018 Nov 4.

1 University of Southern California, Los Angeles, CA, USA.

We report an unusual intrasinusoidal growth pattern of an intraabdominal diffuse large B-cell lymphoma both clinically and histologically mimicking a metastatic adenocarcinoma. A 66-year-old woman presented with a high-grade distal biliary stricture with multiple enlarged abdominal lymph nodes. Frozen section at the time of pancreatoduodenectomy ("Whipple") demonstrated cohesive nests of large atypical cells within a totally effaced lymph node presenting a diagnostic challenge. Read More

Clear Cell Variant of a Follicular Thyroid Tumor With Uncertain Malignant Potential: A Case Report.

Int J Surg Pathol 2018 Oct 29:1066896918809490. Epub 2018 Oct 29.

1 Department of Pathology and Cytology, Karolinska University Hospital, Stockholm, Sweden.

Follicular neoplasms of the thyroid gland are most often characterized by follicular-patterned thyrocytes with a neutrally stained cytoplasm, while a minority of cases present with oncocytic differentiation (Hürthle cell tumors). Exceedingly rare variants with a clear cell phenotype have also been reported, both as clear cell follicular thyroid adenomas (ccFTAs) and clear cell follicular carcinomas (ccFTCs). We present a patient with a 30-mm lesion in the thyroid isthmus in which the preoperative cytology proposed a follicular tumor. Read More

Synchronous Pulmonary Adenofibroma and Solitary Fibrous Tumor: Case Report and Review of the Literature.

Int J Surg Pathol 2018 Oct 26:1066896918807302. Epub 2018 Oct 26.

1 Department of Pathology and Laboratory Medicine, Dartmouth-Hitchcock Medical Center, Geisel School of Medicine at Dartmouth, Lebanon, NH.

Pulmonary adenofibroma (PAF) is a rare neoplasm that may be related to solitary fibrous tumor (SFT). A subset of PAFs harbor the NAB2-STAT6 fusion that is typical of SFT, but a significant proportion do not. Their distinction is clinically important as SFTs can potentially have an aggressive clinical course, while there has been no report of a PAF behaving in a malignant fashion. Read More

1 University of Massachusetts Medical School, UMass Memorial Medical Center, Worcester, MA, USA.

Objectives: Transducer-like enhancer of split 1 (TLE1) immunohistochemistry is widely used as a biomarker of synovial sarcoma. Spindle cell or desmoplastic melanoma can morphologically mimic synovial sarcoma. The aim of this study was to investigate the expression of TLE1 in melanomas with a spindle cell morphology.
