Seventy-three cases of malignant, atypical, and multicentric granular cell tumors soft tissue were studied to clarify criteria for malignancy prognostic factors. Six histologic assessed: necrosis, spindling, vesicular nuclei with large nucleoli, increased mitotic activity (> 2 mitoses/10 high-power fields at 200× magnification), high nuclear cytoplasmic (N:C) ratio, pleomorphism. Neoplasms that met three or more these classified as histologically malignant; those one two atypical; displayed...
Occasional glomus tumors display unusual features, such as large size, deep location, infiltrative growth, mitotic activity, nuclear pleomorphism, and necrosis. Although a small number of purportedly malignant have been described, histologic criteria for malignancy in never elaborated. The authors studied 52 (retrieved from their consultation files) previously diagnosed "atypical" or "malignant" by virtue atypia, activity. They evaluated depth, growth pattern, cellularity, grade, figures per...
Oncogenic osteomalacia (OO) is a rare paraneoplastic syndrome of due to phosphate wasting. The phosphaturic mesenchymal tumor (mixed connective tissue variant) (PMTMCT) an extremely rare, distinctive that frequently associated with OO. Despite its association OO, many PMTMCTs go unrecognized because they are erroneously diagnosed as other tumors. Expression fibroblast growth factor-23 (FGF-23), recently described protein putatively implicated in renal tubular loss, has been shown small...
Pigmented villonodular synovitis (PVNS) represents an uncommon benign neoplastic process that may involve the synovium of joint diffusely or focally occur extraarticularly in a bursa (pigmented bursitis [PVNB]) tendon sheath tenosynovitis [PVNTS]). Pathologic specimens hypertrophic appear villous, nodular, villonodular, and hemosiderin deposition, often prominent, is seen most cases. The knee, followed by hip, common location for PVNS PVNB, whereas PVNTS occurs hand foot. also referred to as...
Hibernoma, an uncommon tumor of brown fat, has been described only in a few case reports and small series. The authors reviewed 170 cases hibernoma evaluated the morphologic features behavior this tumor. records from Soft Tissue Registry Armed Forces Institute Pathology 1970 were searched for coded as "hibernoma." Clinical information available slides hibernomas reviewed. Immunohistochemical staining S-100 CD34 was performed on select cases. Follow-up obtained patients' medical records,...
Low-grade fibromyxoid sarcoma (LGFMS), usually a deeply situated mass in adults, is uncommon superficial soft tissue and children. Nineteen LGFMS from our files were studied for clinicopathologic features, the latter including tumor size, growth pattern, cellularity, collagen rosettes, vascularity, nuclear atypia, mitotic rate, necrosis, immunophenotype. The patients included 12 males 7 females who ranged age 2 to 70 years (mean, 29 years). There Tumor locations lower extremity (8), buttock...
Retroperitoneal lesions represent a broad, diverse collection of entities; when they contain fat, the differential diagnosis, which ranges from benign to fully malignant lesions, substantially narrows. Lipomas rarely occur in retroperitoneum; thus, fat-containing this location should never be dismissed as lipoma. Pelvic lipomatosis is overgrowth histologically normal fat extraabdominal compartments pelvis along perirectal and perivesicular spaces. Infants young children develop lipoblastomas...
Primary pulmonary and mediastinal synovial sarcoma is rare poses a diagnostic challenge particularly when unusual histological features are present. We present 60 cases of primary (29 male 27 female subjects; mean age, 42 years) compare our results with five prior series to better define features. Clinically, patients were younger gender bias. Radiologically, tumors well delineated distinctive magnetic resonance imaging little vascular enhancement. In all, 21/46 died disease within 5 years....
PURPOSE: To determine the imaging characteristics of soft-tissue myxoma, with emphasis on computed tomographic (CT) and magnetic resonance (MR) findings pathologic comparison. MATERIALS AND METHODS: Records 45 pathologically confirmed myxomas in 44 patients were retrospectively reviewed. Patient demographics radiographs (n = 20), bone scintigrams 2), angiograms 3), ultrasonographic (US) 6), CT 14), MR images 33) evaluated by two musculoskeletal radiologists agreement consensus for lesion...
Six childhood vascular tumors were designated as "malignant endovascular papillary angioendothelioma" by Dabska in 1969. Since then, a few reports of similar cases published, often called "Dabska tumors." Twelve identified review from the authors' institutions. There five men and seven women, including adults. Patient ages ranged 8 to 59 years (mean, 30 years). The occurred dermis or subcutis buttocks thigh (n = 6), thumb hand 3), abdomen 2), heel 1). tumor sizes 1 more than 40 cm 7.0 cm)....
