Abstract
Solitary fibrous tumor (SFT) can occur in varied anatomic locations, most commonly being the extremities-superficial and deep soft tissues, followed by retroperitoneum, visceral organs, and the bone. Head and neck region may harbor a few with a predilection for the orbit and sinonasal tract, oral cavity, and rarely the salivary glands. The parotid gland is most involved among all salivary glands. Overall, SFT in salivary glands is rare and mostly seen as a primary tumor. The occurrence of metastasis to the parotid gland is exceedingly uncommon. We present cytological findings of SFT, metastatic to the parotid gland in a young 31-year-old lady where the diagnosis was confirmed with the help of immunocytochemistry (ICC) on the cell block. The smears were highly cellular and showed predominantly discrete round to oval tumor cells with mild pleomorphism, coarse chromatin, inconspicuous nucleoli, and scanty cytoplasm. Mitosis and focal areas of necrosis were noted. Lymphoglandular bodies were absent ruling out a non-Hodgkin lymphoma. Features were of a poorly differentiated malignant tumor with differentials being sarcoma, myoepithelial carcinoma, and carcinoma ex-pleomorphic adenoma. A panel of ICC was done and positivity for signal transducer and activator of transcription 6 (STAT6) helped in clinching the correct diagnosis of SFT.

Abstract
Background Chondrosarcoma is a malignant tumor of chondrogenic origin and the mesenchymal type is a very rare finding. Mesenchymal chondrosarcoma tends to develop mostly in the skeleton but may also occur as a primary tumor in periosteal nervous and muscular tissues, the anterior cerebral falx, meninges, brain, maxillary sinus, eyelid, thyroid, pleura and mediastinum, while in the abdomen the most frequent locations are the kidney, retroperitoneum and even the perineum and the anogenital area. Apparently, the only splenic mesenchymal chondrosarcoma in the literature occurred in a dog. Methods and study design Our paper reports the case of a patient who had a diagnosis of mesenchymal chondrosarcoma of the spleen. Results We adopted surgery as the main therapeutic procedure without achieving complete recovery but preserving a good quality of life for our patient, minimizing the repercussions of the disease on her working and relational life. Conclusions The absence of important or invalidating symptoms and the persistence of good general conditions before and after each surgical operation encouraged us to adopt the surgical option as the most rational.

Abstract
Haemangiopericytoma (HPC) is a rare vascular tumor with borderline malignancy, considerable histological variability, and unpredictable clinical and biological behavior. HPC can present a diagnostic challenge because of its indeterminate clinical, radiological, and pathological features. HPC generally presents in adulthood and is equally frequent in both sexes. HPC can arise in any site in the body as a slowly growing and painless mass. The precise cell type origin of HPC is uncertain. One third of HPCs occur in the head and neck areas. Exceptional cases of hemangioblastoma arising outside the head and neck areas have been reported, but little is known about their clinicopathologic and immunohistochemical features. This study reports on a case of a large sacro-anterior HPC in a 65-year-old male.

Abstract
INTRODUCTION Hemangiopericytoma (HPC)/solitary fibrous tumor (SFT) is a very uncommon tumor of uncertain malignant behavior. In 1942, Stout and Murray first characterized these neoplasms as "vascular tumors arising from Zimmerman's pericytes" and till now hemangiopericytomas and solitary fibrous tumors of the soft tissues are regarded as features of the same entity in the soft tissue fascicle. PRESENTATION OF CASE We present a case of hemangiopericytoma/solitary fibrous tumor of the pectoralis major muscle in a 33-year-old female. She first noticed a painless mass in her right breast. Ultrasound of the breast revealed a large heterogeneously hypoechoic lesion within the pectoralis major muscle. Fine needle aspiration of the tumor did not produce any meaningful result. The lesion was completely removed by surgical resection. Histologically, the tumor had staghorn-like vasculature and immunohistochemistry for CD34 was positive, whereas desmin, smooth-muscle actin, S-100 protein, cytokeratins (AE1/AE3) and epithelial membrane antigen (EMA) were all negative. A diagnosis of hemangiopericytoma/solitary fibrous tumor was rendered. DISCUSSION Tumors comprising the HPC/SFT spectrum represent a small subset of soft tissue sarcomas and are found virtually at any site in the body. Wide surgical resection can achieve favorable long-term survival. CONCLUSION Due to the rarity and unpredictable biological potential of these tumors, long-term follow-up is mandatory even after radical resection, because recurrence or development of metastasis may be delayed many years.

Abstract
INTRODUCTION In 2002, the World Health Organization reclassified the soft tissue tumors known as hemangiopericytoma (HPC) as a variant of solitary fibrous tumor (SFT). As this classification system is still debated and has not been universally applied, the following account will provide an updated review of our understanding of those tumors still classified as HPC in the literature with special emphasis on hepatic HPC/SFT. HPC is a soft tissue neoplasm of mesenchymal origin first described by Stout and Murray in 1942. HPC constitutes 1 % of all vascular neoplasms and has been thought to coexist with trauma, prolonged steroid use, and hypertension. CLINICAL OVERVIEW Although its presentation may be variable, intrahepatic HPC often presents with the patient's increasing awareness of a painless mass. Marked hypoglycemia may also accompany the neoplasm. Recent evidence suggests that uncontrolled growth may result from a loss of imprinting with overproduction of IGF-II in addition to alternative promoter usage. Diagnostic modalities including imaging, biopsy, and biochemical assays may be used to detect the presence of HPC. As most lesions are benign and slow growing, the prognosis is relatively favorable with 10-year survival between 54 and 70 %. MANAGEMENT Current mainstays of treatment include hepatic resection when possible especially with the use of adjuvant radiotherapy. Chemotherapeutic approaches have been poorly studied and are generally reserved for inoperable cases. Antiangiogenic compounds such as temozolomide and bevacizumab provide an exciting avenue of treatment. Finally, a case study will be reviewed highlighting diagnosis, treatment, and spectrum nature of hepatic HPC.

Abstract
Plexiform fibrohistiocytic tumor is a rare soft tissue tumor that has a propensity to occur in the extremities in adolescents and young adults. Its cytologic features are not well documented, with only two case reports available in the literature. We present the case of a recurrent plexiform fibrohistiocytic tumor in a 19-year-old male, the cytologic features of which mimic that of a high-grade sarcoma. We discuss the likely differential diagnosis based on the cytologic findings and a review of the current literature on this highly unusual tumor is also performed.

Abstract
INTRODUCTION Hemangiopericytoma is an uncommon soft tissue vascular neoplasm. Intraperitoneal hemangiopericytomas such as primary or secondary liver location have been exceptionally described. Its natural history is mostly benign, but recurrences may occur and determining if these late-discovered tumors are distant metastases or synchronous slow and silent-growing locations is sometimes challenging. The histopathological diagnosis and definition of hemangiopericytoma is based on its distinction with solitary fibrous tumors. Liver resection to treat liver hemangiopericytoma seems to be supported by various published experiences. CASE PRESENTATION We herein report the first case of liver metastases from a subcutaneous temporal hemangiopericytoma. The patient was treated by a liver resection. CD34 Immunostaining was negative, but strong expression of Bcl2 and CD99 was found in the neoplastic cells. After 1 year of follow-up, the patient is alive without recurrence. CONCLUSION To date, published data, including the case herein reported, support the need for a prolonged follow-up and the role of liver resection to treat liver metastases of hemangiopericytomas. Complete resection of all gross disease appears to be the most significant prognostic factor.

Abstract
BACKGROUND: Hemangiopericytoma (HPC) is a rare vascular tumor originating from the capillary pericytes, and HPC of the breast is extremely rare. CASE REPORT: We describe a 50-year-old woman with HPC of the breast and focus on the diagnosis before operation and the extent of the operation. Under local anesthesia, a complete tumor excision was performed. Then, the fast-frozen material was pathologically examined and the diagnostic conclusion was 'malignant tumor of the breast, perhaps original from lobus intermedius tissue'. Finally, a modified radical mastectomy was performed, after which all 7 lymph nodes from the axillary fossa position of the excision showed symptoms of reactive hyperplasia. CONCLUSION: ON THE BASIS OF REVIEWING THE LITERATURE ABOUT THE DISEASE, WE PROPOSE SEVERAL BASIC IDEAS: an accurate biopsy together with an appropriate histological and im-munohistochemical examination is promising, and since lymph node metastasis is extremely rare, a simple mastectomy may be considered.

Abstract
Metastases to the kidney from extrarenal primary tumors are uncommon and may mimic renal-cell carcinoma clinically when presenting as a single mass with hematuria. Fine-needle aspiration biopsy (FNAB) is a useful diagnostic method for the evaluation of primary renal tumors. Only a few studies have investigated the value of cytological evaluation of secondary renal tumors. We report our experience with these tumors. Eleven cases of extrarenal primary tumors metastatic to the kidney, diagnosed by aspiration biopsy with histological correlation, are discussed. The diagnosis of metastatic disease to the kidney was accurately made by aspiration biopsy. Knowledge of the patients' history, histological correlation with the primary tumor, and the radiological characteristics of the renal masses were helpful in achieving a correct diagnosis. FNA cytology (FNAC) is an accurate method for the diagnosis of tumors metastatic to the kidney. Distinction between primary and secondary tumors of the kidney is crucial to guide management and prevent unnecessary surgery.

Abstract
The role of fine needle aspiration biopsy (FNAB) as the primary modality for the initial diagnosis of previously undiagnosed soft tissue sarcomas presents several important challenges. Most practicing pathologists are inexperienced with the wide array of soft tissue neoplasms and their morphologic heterogeneity, making them susceptible to misdiagnosis. However, in the hands of experienced cytopathologists, FNAB in conjunction with ancillary techniques has a diagnostic accuracy approaching 95% for the diagnosis of malignancy. FNAB has been shown to have a diagnostic yield nearly identical with core needle biopsy while avoiding significant clinical complications. Nevertheless, FNAB has certain limitations related to the accurate histologic grading and subtyping of certain subgroups of sarcomas. It may also be difficult to accurately distinguish between low-grade sarcomas and benign or borderline cellular lesions, especially in the spindle cell sarcoma subgroup. The aim of this review is to highlight the utility and limitations of FNAB in the primary diagnosis of soft tissue sarcomas, highlight diagnostically challenging lesions, and comment on the limitations of FNAB in providing a "definitive" diagnosis.

Abstract
The glomus tumor is usually a benign solitary neoplasm that arises from modified smooth muscle cells of the glomus body, a type of neuromyoarterial receptor that plays a role in the regulation of arterial blood flow. We report a case of gastric glomus tumor diagnosed by endoscopic ultrasound-guided fine-needle aspiration. Smears exhibited groups of cohesive, uniform, small, round to polygonal cells with scant cytoplasm, indistinct cell borders, and round, hyperchromatic nuclei with homogeneous chromatin. The cell block contained fragments of cells with similar morphologic features and immunohistochemical staining exhibited positivity for smooth muscle actin and vimentin. The diagnosis was confirmed by the surgically resected specimen. Ultrastructural examination revealed prominent pinocytotic vesicles lining the plasmalemma. In this report, we discuss the differential diagnosis of gastric glomus tumor and compare the cytologic features of this case with two others reported in the literature.

Abstract
Purely benign mesenchymal spindle cell neoplasms of the breast are currently labeled under various terms in the literature (benign spindle cell tumor, fibroma, spindle cell lipoma, myofibroblastoma, solitary fibrous tumor, myogenic stromal tumor). The lack of strict diagnostic criteria to clearly indicate such mesenchymal neoplasms is the main reason which generated the risk of terming the same lesion under different names or, conversely, of collecting different types under the same term. Although such neoplasms exhibit morphological and immunophenotypical heterogeneity, they actually represent variations of the same tumor entity, likely arising from the uncommitted vimentin+/CD34+ fibroblasts of the mammary stroma, capable of multidirectional mesenchymal differentiation. To cover the entire spectrum of such lesions, the term "benign spindle cell tumors (BSCTs) of the mammary stroma" is advocated. BSCTs can be subtyped into four main groups by light microscopy (LM) and immunocytochemistry (ICC): fibroblastic, myofibroblastic, fibrohistiocytic, and mixed forms. A simple and practical approach to a nosologically correct diagnosis and a list of differential diagnoses are presented. The awareness of the diversity of morphological and immunophenotypical features of BSCTs of the mammary stroma, including uncommon variants, is helpful to avoid confusion with other monomorphic bland-looking benign and malignant spindle cell tumors and tumor-like lesions of the breast.

Abstract
A glomus tumor of the stomach was found as an incidental finding on routine ultrasound in a 72-yr-old asymptomatic woman. A fine-needle aspiration biopsy (FNAB) was performed and was initially interpreted as a well-differentiated neuroendocrine neoplasm, possibly a carcinoid tumor. The aspirate revealed tightly packed nests or clusters of uniform, small, round to polygonal cells with scanty, faintly eosinophilic or clear cytoplasm and ill-defined cell borders. The nuclei were uniform, and round to oval, and contained a granular chromatin pattern and inconspicuous nucleoli. Very occasional intranuclear cytoplasmic inclusions were seen. Laparotomy and a wedge resection of the stomach were performed. The surgical pathology findings revealed a glomus tumor which was confirmed by immunohistochemical stains and ultrastructural studies. Since glomus tumors of the stomach are essentially benign and are amenable to conservative excision, it is important to separate them, preoperatively, from more aggressive gastric neoplasms. FNAB offers a rapid, cost-effective method of diagnosing this entity. We present the cytological, histological, ultrastructural, and immunocytochemical features of this particular gastric neoplasm, along with differential diagnoses.
