Summary Liposarcoma is one of the most common soft tissue sarcomas in adults with a relative incidence amongst other sarcomas ranging from 9.8% to 16%. It usually locates in the limbs and retroperitoneum. Primary liposarcomas of the larynx and hypopharynx are rare, comprising less than 20% of all head and neck liposarcomas. According to World Health Organization, these tumors are divided into four histologic types, and well-differentiated liposarcoma is the most common one. It is a tumor of low-grade malignancy that may recur locally, but does not metastasize. We present a case of laryngopharyngeal well- differentiated liposarcoma in an old patient with two previous removals. We also discuss recently published cases with this unusual location of liposarcoma.

Abstract Liposarcoma is one of the most common soft tissue sarcomas and has multiple subtypes, including atypical, well-differentiated, and dedifferentiated liposarcoma1. These tumors most commonly occur in the extremities and the retroperitoneum2, and account for 20% of all retroperitoneal tumors3. Retroperitoneal liposarcoma is very rare overall, occurring in 2.5 per one million people4. Patients will present from symptoms of mass effect due to the uncontrolled growth in the large potential space of the retroperitoneum, with its median size being around 30 cm5. The mainstay of treatment for this type of tumor is resection to a negative margin6. This is a case report describing a retroperitoneal liposarcoma presenting with bilateral inguinal hernias containing intraperitoneal fat from mass effect.

Mixed adenoneuroendocrine carcinomas are rare tumors that contain both an exocrine and an endocrine component. Since the latest classification by the World Health Organization and with the aid of immunostaining, more mixed adenoneuroendocrine carcinomas are now identified and diagnosed. Nonetheless, our knowledge of these tumors is still limited, notably concerning gastric variants, as the cases reported in the literature are very limited. The clinical and surgical treatment, including the chemotherapy schemes, the prognosis, and recurrence still represent challenges for the medical teams. We present the case of a 62-year-old woman. After an upper endoscopy revealed multiple polyps and a low-grade neuroendocrine tumor, a D2 radical gastrectomy was performed. A low output esophageal anastomotic leak was discovered in the postoperative period and successfully managed. Pathology revealed a gastric mixed adenoneuroendocrine carcinoma, the first case of this kind reported in Ecuador. Patient is doing well and under constant surveillance up until her 13th postoperative month.

Abstract Ameloblastic fibrosarcoma (AFS) is a rare, aggressive malignant odontogenic tumor. AFS is seen most frequently in second and third decades of life. We are reporting a case of a low grade AFS in a 21-year-old male complaining of a painless swelling in the right side of the maxilla. The patient was treated with surgical excision followed by radiotherapy, which is considered the most effective approach for most of soft tissue sarcomas. AFS has a high-reported recurrence rate (up to 37%); therefore, long-term surveillance for recurrence is crucial.

Sarcomas are relatively rare, accounting for only 1% of all adult malignancies and 15% of childhood malignancies [2]. According to the World Health Organization (WHO), the group of soft tissue sarcomas includes more than 100 different histological subtypes [3]. According to the recommmendations of the WHO to improve the accuracy of diagnosis in soft tissue sarcoma, the traditional histopathological examination should be supplemented with immunohistochemical and molecular methods [1]. It was carried out immunohistochemical research of CD31 receptor of Vascular Endothelial Growth Factor (VEGF) in 129 patients with STS. The age range of patients is on average 14-77 years with a peak in the age of 50-59 years. The most common reason for initial visit to a medical institution was palpable tumor (100%). It was studied the following correlative interdependences: It was determined that histodifferentiation of tumour is in inverse correlation with expression CD31 receptor. Distinctions of expression level of CD31 are shown, depending on the degree of tumor differentiation, presence or absence of its spontaneous necrotization, limphoid infiltration of pathological nidus and amount of vessels in tumor tissue. That is as high the degree of histological differentiation of tumour as low the level of expression CD31 receptor (χ2=35,4; p<0,001; р=-0,322). In FHTof ST is exposed inverse dependence between expression CD31 endotelial cells with spontaneous necrosis and lymphoid infiltration. As more the size and foci of spontaneous necrosis (χ2=67,1; p<0,001; р=-0,473) and lymphoid infiltration (χ2=46,1; p<0,001; р=-0,346), as low the level of expression CD31 receptor. It was found that the high level of espression CD31 receptor is in direct correlation with metastasis (χ2=18,6; р=0,42; p<0,001) and recurrence (χ2=9,43; р=0,30; p<0,01) of the process. Studied modern approaches to the diaqnostics and treatment of malignancies. One such approach is ”Oncology Control”, which means minimizing the risk of recurrence at the local and systemic level. Following treatment, follow-up should include history and physical examination accompanied by imaging (Ultrasound or MRI) every 3 to 6 month for 2 to 3 years, and then every 6 to 12 months thereafter to asses for recurrence. So in high positivity of CD31 receptor is exposed unfavourable prognosis in patients with STS. Summarizing before said we have come to the conclusion that immune-histo-chemical investigation of CD31 receptor of VEGF has important prognostical meaning in patients STS.

La acupuntura es una técnica de origen chino que surge hace aproximadamente 2000 años. Es una modalidad terapéutica que ha cobrado gran importancia en el mundo occidental para el tratamiento de diversos cuadros, incluida la lumbalgia. Comunicamos el caso de un hombre de 74 años de edad, que consulta por reagudización de la lumbalgia crónica, luego de un tratamiento alternativo, a quien se le diagnostica una complicación infecciosa. Si bien, en manos experimentadas e instruidas, es una técnica con relativamente escasas complicaciones, se han publicado diversos reportes que describen complicaciones, en su mayoría, menores y asociadas a una técnica estéril insuficiente o a falta de conocimiento por parte del acupunturista. El auge de estas técnicas alternativas puso el foco en las medidas de seguridad, por lo cual entes, como la Organización Mundial de la Salud han creado guías para su correcto uso. Conocer las posibles complicaciones facilita el diagnóstico temprano y el tratamiento. Se analiza la presentación clínica y se realiza una revisión bibliográfica del cuadro. AbstractAcupuncture originated in China approximately 2000 years ago and is a growing modality of treatment worldwide sought by patients for a variety of conditions including lumbar pain. We report a case of a 74 years old man who had received acupuncture to treat lower back pain, who subsequently presented an increased in his pain; an infection was diagnosed, and treated. Despite acupuncture can be considered inherently safe in the hands of well-trained practitioners, we found different reports of complications in worldwide literature; most of them minor, and usually as a result of inappropriate technique. The popularity of this alternative treatments, has made organizations, such as World Health Organization (WHO), create guidelines to reassure its safety. The knowledge of the possible complications, allow the early diagnosis and treatment. The case is discussed, and pertinent review of literature is included.

Myofibroblastic Differentiation

Low-grade myofibroblastic sarcoma (LGMS) is an exceedingly rare, malignant tumor with myofibroblastic differentiation. It frequently occurs in the oral cavity and extremities, despite being classified as a distinct entity by the World Health Organization (WHO). Here, we report a rare case of orbital LGMS occurring in an 11-month-old baby with a 3.2 × 2.4 × 2.1 cm mass. LGMS was diagnosed based on the histological and immunohistochemical findings. Previous literature suggests that surgical resection with clear margins is an appropriate method for the treatment of LGMS, and combined adjuvant therapy (local radiotherapy with or without chemotherapy) can improve the prognosis, but further studies are needed.

Retroperitoneal sarcomas are a heterogenous group of rare tumors arising in the retroperitoneum. Retroperitoneal sarcomas comprise approximately 10% of all soft tissue sarcomas. Though any soft tissue sarcoma histologic types may arise in the retroperitoneal space, liposarcoma (especially well-differentiated and dedifferentiated types) and leiomyosarcoma do so most commonly. Retroperitoneal sarcomas are diagnostically challenging, owing to their diversity and morphological overlap with other tumors arising in the retroperitoneum. An accurate diagnosis is necessary for correct management and prognostication. Herein, we provide an update on the diagnostic approach to retroperitoneal sarcomas and review their key histologic findings and differential diagnoses.

Context.— Neoplasms originating in the thalamus are rare overall (1% of all brain tumors); however, they comprise approximately 5% of pediatric intracranial tumors and approach 15% of all malignant pediatric intracranial tumors in some series. Objective.— To update readers about the current understanding of the diverse histology, biology, and behavior of pediatric thalamic tumors. Histologic verification is now thought to be critical for planning treatment, and, as a result, biopsy and total/subtotal resections are much more common today than in the past. Data Sources.— A PubMed search using the keywords “pediatric + thalamic + glioma” yielded 45 publications with a total of 445 cases of thalamic gliomas in patients less than 18 years of age. We found only 9 substantial institutional series tabulating all encountered thalamic histologic types in children. This survey confirmed a high proportion of astrocytomas, 81% (214 of 265), of which approximately two-thirds were diffuse astrocytomas (146 of 214) and one-third were pilocytic astrocytomas (68 of 214). Of the diffuse astrocytomas, 34% (49 of 146) were low grade (World Health Organization grade II) and 55% (81 of 146) were high grade (World Health Organization grade III or IV), making the latter subgroup the largest single category of all pediatric thalamic tumors. Oligodendrogliomas and ependymomas (mostly anaplastic in both cases) comprised 10% and 3% of all pediatric thalamic tumors, respectively. Conclusions.— Tissue diagnosis is now thought crucial for prognostication and treatment, particularly as more potentially therapeutic molecular targets are discovered. Secure diagnosis allows identification of tumors for which resection is more feasible and beneficial.
