Sinonasal organized hematoma: Case report and review of the literature.

Sinonasal organized hematoma is a rare condition characterized by an organizing blood clot in the sinonasal cavity, which consists of blood products, fibrin, and dilated blood vessels. As a benign entity with an aggressive imaging appearance, it is important to differentiate sinonasal organized hematoma from malignancies affecting the paranasal sinuses and nasal cavities to guide appropriate management. In this report, we discuss the clinical presentation and diagnostic evaluation of an 82-year-old male with a left maxillary sinus organized hematoma and provide a comprehensive review of the relevant literature.

Lymph Node and Distant Metastases in Phyllodes Tumor of the Breast.

A 54-year-old woman who incidentally noticed a "knot" in her left breast subsequently underwent excisional biopsy which yielded a diagnosis of malignant neoplasm with sarcomatous features. Given the broad differential diagnosis and imaging findings, the patient underwent bilateral mastectomy and intraoperative sentinel lymph node assessment. An 8.

Intraductal Papilloma on Breast Biopsy: Upstaging Rate and Implications for Practice Guidelines.

Background: The recommendation for management of intraductal papilloma has not been clearly established and its surgical excision criteria remain controversial. This study determines the institutional malignancy upstage rate of benign intraductal papillomas and identifies risk factors for upstage.

Methods: Retrospective review was conducted on female patients who were diagnosed with intraductal papillomas without atypia on core needle biopsy at Atrium Health Wake Forest Baptist Hospital between 1/2012 and 6/2021.

Upstage Rate of Complex Sclerosing Lesions/Radial Scars.

Background: Radial scars (RS) and complex sclerosing lesions (CSL) are breast radiologic findings described as small, stellate lesions causing architectural distortion. This can mimic malignancy. Core needle biopsy (CNB) is often performed.

Is Excisional Biopsy Needed for Pure FEA Diagnosed on a Core Biopsy?

Background: The management of flat epithelial atypia (FEA) on core needle biopsy remains controversial. The upstaging rates after surgical excision are variable. In this study, we seek to determine the upstaging rate of FEA at our institution.

Negative Heparin-Induced Thrombocytopenia Test Result After Massive Transfusion: Believe It or Not?

Objectives: Diagnosis of heparin-induced thrombocytopenia (HIT) is complicated by a high false-positive rate for the screening enzyme immunoassay (EIA) and limited availability of confirmatory platelet activation assays such as serotonin release assay (SRA). We evaluate the impact of a massive transfusion on EIA and SRA testing and emphasize that the timing of the confirmatory sample is important.

Methods: We present a case in which separate samples for HIT testing were collected before and after a major bleed requiring massive transfusion.
