    Phosphohistone-H3 and Ki67: Useful Markers in Differentiating Dermatofibroma From Dermatofibrosarcoma Protuberans and Atypical Fibrohistiocytic Lesions.
    Am J Dermatopathol 2017 Jul;39(7):504-507
    *Department of Pathology, Baylor University Medical Center, Dallas, TX; †Department of Pathology, Pathologist Biomedical Laboratories, Dallas, TX; ‡Department of Pathology, UF Health, Jacksonville, Jacksonville, FL; §Department of Pathology, The University of Texas MD Anderson Cancer Center, Houston, TX; and ¶Department of Pathology, MD Anderson Cancer Center, Houston, TX.
    Dermatofibromas (DF) are common, benign, skin tumors, usually easily differentiated from dermatofibrosarcoma protuberans (DFSP) by the presence of a relative low cellularity, lesser degree of infiltration of subcutaneous tissue, and immunohistochemical pattern (eg, FXIIIa in DF and CD34 in DFSP). Atypical fibrohistiocytic lesions (AFL) have features intermediate to DF and DFSP (trunk location, storiform pattern, infiltration of the subcutaneous tissue, and focal expression of both CD34 and Factor XIIIa). It is unclear if mitotic counts/degree of proliferation is helpful to distinguish DF from DFSP. Read More

    Cutaneous malignancies simulating seborrheic keratoses: An underappreciated phenomenon?
    J Cutan Pathol 2017 Sep 2;44(9):747-748. Epub 2017 Jul 2.
    Department of Dermatology, University of Texas Southwestern Medical Center, Dallas, Texas.
    Background: Seborrheic keratosis (SK), a common and benign entity, is generally diagnosed clinically without the need for a biopsy. Given their variable appearance, SK may mimic cancer clinically and require biopsy for clinically equivocal cases. A clinician may also choose to perform biopsies on SK based on other circumstances, such as cosmetic reasons or SK being in an inconvenient and irritative location. Read More

    Xanthomatous Posttraumatic Fibro-Osseous Lesion of the Rib: A Rare and Underrecognized Entity. Case Report and Literature Review.
    Int J Surg Pathol 2017 Oct 4;25(7):640-643. Epub 2017 Jun 4.
    1 Bichat Hospital, AP-HP, Paris, France.
    Posttraumatic fibro-osseous lesion (PTFOL) is a rare lesion that typically affects the ribs and is probably a posttraumatic reactive process. Because PTFOL is often misdiagnosed as fibrous dysplasia, osteoid osteoma, benign fibrous histiocytoma or rib metastases, chest wall resection, leading to a significant morbidity, is the main treatment modality. We report the case of a 30-year-old male patient with no history of previous trauma presenting with chest pain. Read More

    The Immunological Roles of Periostin/Tumor-Associated Macrophage Axis in Development of Dermatofibrosarcoma Protuberans.
    Anticancer Res 2017 06;37(6):2867-2873
    Department of Dermatology, Tohoku University Graduate School of Medicine, Sendai, Japan.
    Background/aim: Dermatofibrosarcoma protuberance (DFSP) is a fibrohistiocytic tumor of intermediate malignancy characterized by slow infiltrative growth and a high tendency to recur locally. Periostin is involved in modulating cell function and inducing the production of proinflammatory cytokines, chemokines, and matrix metalloproteinases (MMPs) from tumor-associated macrophages (TAMs) to promote fibrosis and tumor growth. This study aimed to examine the cancer stroma of DFSP, focusing on TAMs-related proteins and MMPs. Read More

    Pathologically Benign Lymph Nodes Can Mimic Malignancy on Imaging in Patients With Angiomatoid Fibrous Histiocytoma.
    Clin Orthop Relat Res 2017 Sep 23;475(9):2274-2279. Epub 2017 May 23.
    Department of Surgery, Memorial Sloan Kettering Cancer Center, New York, NY, USA.
    Background: Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue neoplasm, and its rarity makes studying it difficult. We found that several of our patients with AFH presented with radiologically suspicious local lymph nodes that were sampled because of their imaging characteristics, but the nodes proved to be benign on pathologic evaluation. Although the frequency of this finding is unknown, it seems important for orthopaedic oncologists who care for patients with AFH to know whether suspicious-appearing associated nodes in these patients warrant aggressive management.

    Lung 2017 Aug 11;195(4):503-506. Epub 2017 May 11.
    Respiratory Division, University Hospital Limerick, Limerick, Ireland.
    The following report describes the case of a 43-year-old male smoker that was referred to the rapid access lung clinic with haemoptysis, chest pain, and axillary lymphadenopathy-a clinical picture that raised concern for a possible underlying malignancy. Preliminary investigations revealed elevated D-dimers, low-volume haemoptysis, and a normal chest X-ray, which lowered the index of suspicion. However, computed tomography (CT) pulmonary angiogram identified a right hilar mass, several parenchymal cysts, and a large mediastinal mass. Read More
