Since this method was successful in this case, a case series is warranted.
Extraskeletal Ewing's sarcoma is a rare malignant tumor of mesenchymal origin, which is histologically similar to primary osseous Ewing's sarcoma. It has been well described in deep soft tissues. However, location in cutaneous or subcutaneous tissue has rarely been reported. Being seen principally in children, it can be seen, rarely, in old men.
We present a case of large primary cutaneous Ewing sarcoma within the left thigh of a 35-year-old woman, without osseous involvement. Physical examination. MK-8245 inhibitor Histologically, it was a small round cell tumor that marked strongly for CD99. The diagnosis of cutaneous Ewing sarcoma was performed.
The things that distinguish our case are that it is the first case in Syria, in addition to the size of the large tumor with diameters of 15×20cm, and it is in a 35-year-old woman.
Ewing sarcoma is a rare malignant small round cell tumor of the skin and subcutaneous tissue. It should be differentiated from other cutaneous neoplasms composed of small round cells.

Primary testicular lymphoma (PTL) is a variety of extra-nodal lymphoma taking origin from testis. It accounts 5% of all testicular tumors. Metastasis may occur in contralateral testis, bone, central nervous system and rarely in skin. Herein, we present the case of testicular diffuse large B-cell malignant lymphoma with cutaneous metastasis.
A 60-year-old male presented with swollen painless solid right testis, with homolateral inguinal nodes. Testicular tumors markers were within normal range. Right radical orchidectomy was performed. Histopathological examination concluded to the diagnosis of Diffuse Large B Cell Lymphoma. Four weeks later, the patient presented alteration of general condition and multiples cutaneous centimetric lesions located in the right inguinal region. Biopsy of this lesion confirmed the diagnosis of metastases from the testicular lymphoma. The patient deceased three days later, before starting further treatment.
Primary testicular lymphoma is a rare variety of testicular tumors. The prognosis is poor. Metastasis may occur in different sites such as contralateral testis, central nervous system, and skin. The prognosis is usually poor in the rare case of cutaneous metastasis.
Primary testicular tumor is an aggressive rare variety of testicular tumors with poor prognosis. Cutaneous metastasis is rarely reported. Cutaneous lesions should be explored and suspected to be malignant. Early treatment with rapid multidisciplinary management is the key for adequate approach.

Fibrosarcoma is a rare malignant tumor comprising spindle-shaped fibroblasts exhibiting variable collagen production. Adult-type fibrosarcoma (AFS) mainly occurs in people aged between 30 and 80years, primarily in the deep soft tissues of the trunk, neck, and extremities, especially in areas surrounding bones. Juvenile fibrosarcoma(JFS) is a type of AFS that occurs in adolescents and rarely develops in the abdominal cavity.
A 13-year-old girl presented with right upper quadrant pain for 5days. Abdomen and pelvis computed tomography showed a 12×6-cm, ill-defined, lobulated, solid, cystic mass in the abdominal cavity. On laparoscopy, there were two masses in the abdominal cavity. One abutted the stomach and severely adhered to the gallbladder. The second mass was located between the transverse colon and duodenum, and it was surrounded by the omentum. The tissues surrounding the masses were finely dissected, and the two masses were excised completely. The patient was discharged without complications on post-operative day 7.
JFS, AFS in adolescents, is a rare malignant tumor. And there have been no reported cases of multiple JFS in abdominal cavity. Surgical excision is the gold standard of treatment for localized AFS, and the laparoscopic approach for minimal tumor handling is beneficial.
We describe a rare case of multiple intra-abdominal juvenile fibrosarcoma, managed through laparoscopic surgery.

Angiosarcoma is a very rare malignancy, which varies based on the location and organ affected. A clinicopathological form of cutaneous angiosarcoma (CAS) involves the head scalp, face, and neck. We report a 59-year-old female patient with CAS on the temporoparietal region of the scalp.
The patient presented with lesions in the head area, which appeared suddenly in the last 6months, (before her surgery). Excision was performed under general anesthesia for bleeding as indicated on the right temporal region. The excision procedure was carried out three times at various stages, and then closed with skin grafts. Pathological examination of the three excised tissues showed progression, leading to CAS. Based on the clinical picture and anatomical assessment, a consultation with the surgical oncology department was necessary for further treatment.
Angiosarcoma has a high rate of progression. The onset of lesions, which are difficult to detect, does not often lead to progression. Other macroscopic features appeasion of any remaining lesions.
The ectopic eruption of the teeth into the nasal cavity is a rare phenomenon. It is mostly found incidentally or with nasal symptoms.
A 32-year-old male patient presented with nasal obstruction and recurrent epistaxis. Nasal endoscopy revealed a mass in left nasal floor along with septal deviation and right inferior turbinate hypertrophy. Sinus CT confirmed the same clinical finding with emphasis on the mass being a foreign body mostly consistent with a tooth. Septoplasty, inferior turbinoplasty, and endoscopic removal of the nasal tooth were performed. The patient tolerated the procedure well with improvement in nasal symptoms.
The exact etiology of supernumerary teeth is still unclear. There are different clinical presentations that can occur; however, the intranasal tooth can be asymptomatic or cause a variety of signs and symptoms. The diagnosis of nasal teeth is usually made by the clinical and radiographic findings, and removal of the nasal teeth is generally advised to alleviate the symptoms and prevent complications.
Ectopic eruption of the teeth into the nasal cavity is a rare form of supernumerary teeth. Thus, crucial attention to the clinical, radiological and histopathological examination should be taken for more accurate diagnosis and thus appropriate management in case of nasal obstruction or recurrent epistaxis.

In principle, soft tissue surface is smooth and watery with sparse texture, specular reflection, and frequent deformation. As a result, we frequently obtain only sparse feature points that give rise to incorrect matching results with conventional image processing methods. To ameliorate, in this paper we enunciate an accurate and robust description and matching method for dense feature points in endoscopic videos. Our new method first extracts contours of the low-rank image sequences based on the adaptive robust principal component analysis (RPCA) decomposition. Then we propose a multi-scale dense geometric feature description approach, which simultaneously extracts dense feature descriptors of the contours in the original Euclidean coordinate space, thh potential in 2D/3D reconstruction in endoscopy.
We aim to evaluate a deep learning (DL) model and radiomic model for preoperative differentiation of nodular cryptococcosis from solitary lung cancer in patients with malignant features on CT images.
We retrospectively recruited 319 patients with solitary pulmonary nodules and suspicious signs of malignancy from three hospitals. All lung nodules were resected, and one by one radiologic-pathologic correlation was performed. A three-dimensional DL model was used for tumor segmentation and extraction of three-dimensional radiomic features. We used the Max-Relevance and Min-Redundancy algorithm and the eXtreme Gradient Boosting algorithm to select the nodular radiomics features. We proposed a DL local-global model, a DL local model and radiomic model to preoperatively differentiate nodular cryptococcosis from solitary lung cancer. The DL local-global model includes information of both nodules and the whole lung, while the DL local model only includes information of solitary lung nodules. Five-fold cross-validdular cryptococcosis and lung cancer nodules which are hard to be diagnosed by the combination of CT imaging, laboratory results and clinical data, and overtreatment may be avoided.

Real time localization and shape extraction of guide wire in fluoroscopic images plays a significant role in the image guided navigation during cerebral and cardiovascular interventions. Given the complexity of the non-rigid and sparse characteristics of guide wire structures, and the low SNR(Signal Noise Ratio) of fluoroscopic images, traditional handcrafted guide wire tracking methods such as Frangi filter, Hessian Matrix, or open active contour usually produce insufficient accuracy with high computational cost, and may require extra human intervention for proper initialization or correction. The application of deep learning techniques to guide wire tracking is reported to produce significant improvement in guide wire localization accuracy, but the heavy calculation cost is still a concern.
In this paper we propose a two phase deep learning scheme for accurate and real time guide wire shape extraction in fluoroscopic sequences. In the first phase we train a guide wire localization network to pick image that our proposed method can achieve more accurate and stable performance. Compared with other deep learning methods, our proposed method significantly improve calculation efficiency to meet the real time requirement of clinical applications.Control of appetite and feed intake in fish larvae are still largely unexplored. Two of the key players in controlling vertebrate's feed intake are cholecystokinin (CCK) and peptide YY (PYY). Here we investigated the mRNA expression of pyy, cck and cck receptors (cckr) in the brain (head) and gut of Atlantic halibut larvae in response to three consecutive meals. We used Artemia nauplii cysts that are commonly ingested by halibut larvae when present as inert feed, and three water-soluble extracts as attractants to stimulate appetite. Cyst intake was not affected by the use of attractants and overall ingestion rate was low. Differences in mRNA expression of cck and pyy were observed between the halibut larvae that had eaten and those that had not despite readily available feed (cysts), supporting that mechanisms for control of feed intake are at least partly functional. All genes analysed were present in the brain and gut, however the different expression profiles between paralogues suggest potential divergent functions.
