Case of primary dural epithelioid angiosarcoma with review of literature and differential diagnosis.

The central nervous system (CNS) is an uncommon site for primary epithelioid angiosarcoma. We report a case of a 25-year-old male who presented with swelling over the head, headache, and weakness of the right side for 6 months. MRI revealed a heterogeneously intense large left parietal dural-based, extra-axial mass with dural tail infiltrating the brain parenchyma, overlying calvaria along with mass effect and vasogenic edema in the left parietal lobe. The patient underwent complete resection of the tumor with adjuvant radiotherapy. Histology revealed a mitotically active vasoformative neoplasm with epithelioid morphology which was immunoreactive for CD31, ERG, FLI-1, and variably for CK. Based on the histomorphological and immunohistochemical profile, a diagnosis of epithelioid angiosarcoma was rendered. The extreme rarity in this location and the highly malignant nature of this tumor makes the clinical diagnosis and management very challenging. These tumors are often considered as meningiomas on prebiopsy imaging due to dural location and dural tail. Further, the misconception may continue on histological examination if only EMA is utilized, since both meningioma and epithelioid angiosarcoma can be positive. There are only 10 previous reports of meningeal angiosarcoma reported in the literature.

Spindle cell rhabdomyosarcoma in the adult: A rare case report.

Spindle cell/sclerosing rhabdomyosarcoma (RMS) is an uncommon type of RMS and has been classified as a separate entity by the WHO in 2013. It affects both children and adults with a greater incidence in males. These tumors can pose a diagnostic challenge and can be difficult to differentiate from other spindle cell malignant tumors in the head and neck. Here, we report a case of spindle cell/sclerosing RMS in a young woman presenting with a swelling on the left side of the face of 3 months duration. A careful correlation with the radiographic images, histopathological findings and immunohistochemistry helped to arrive at a diagnosis.

The Hidden Costs of Reconciling Surgical Sponge Counts.

Retained surgical sponges are serious adverse events that can result in negative patient outcomes. The primary method of prevention is the sponge count. Searching for sponges to reconcile counts can result in inefficient use of OR time. The purpose of this descriptive study was to estimate the cost of nonproductive OR time (ie, time spent not moving forward with the surgical procedure) spent reconciling surgical sponge counts and the cost of using radiography to rule out the presence of retained sponges. We included 13,322 patient surgeries during a nine-month period. Perioperative personnel required from one to 90 minutes of additional time to reconcile each of 212 incorrect/unresolved counts. The total annualized cost of OR time spent searching for sponges and ruling out the presence of potentially retained sponges using radiography was $219,056. These costs should be included in comprehensive cost analyses when considering alternatives to supplement the surgical count.

Glomus tumor of the nail unit.

Glomus tumor is a benign tumor arising from the neuromyoarterial plexus concentrated beneath the nail. This plexus is an arteriovenous anastomosis functioning without the intermediary capillary bed. Etiology is not exactly known. It is debilitating to the patient because of the chronicity of symptoms and lack of proper investigation which will help in identifying the tumor at an early stage. We report a case of glomus tumor situated in the proximal nail fold region and causing longitudinal splitting of nail.
