1. Non-alpine primary thyroid angiosarcoma
SUMMARY Thyroid angiosarcoma is an extremely rare malignancy, which occurs more frequently in the alpine region, likely associated with iodine deficiency and endemic goiter. This is an aggressive neoplasm that usually harbors a poor prognosis. We report the case of a 49-year-old Portuguese female patient presenting with a large nodule in the anterior neck re

2. Evaluation of different protocols for culturing mesenchymal stem cells derived from murine bone marrow
ABSTRACT Introduction: Culturing bone marrow mesenchymal stem cells (BM-MSCs) is a key point in different fields of research, including tissue engineering and regenerative medicine and studies of the bone marrow microenvironment. However, isolating and expanding murine BM-MSCs in vitro has challenged researchers due to the low purity and yield of obtained c

4. Case for diagnosis. Dorsal nodule in a 10-year-old male,
Abstract Granular cell tumors (GCTs) are rare soft-tissue neoplasms. GCT immunohistochemistry is positive for S-100, NSE, and CD68. This report describes the case of a 10-year-old male who presented with a dorsal nodule. A biopsy revealed aggregates and sheets of large epithelioid and spindle cells. The cells had abundant eosinophilic granular cytoplasm. Imm

5. Superficial Acral Fibromyxoma: Literature Review
Resumo O fibromixoma acral superficial é um tumor raro de tecidos moles. Geralmente se manifesta por meio de uma massa indolor de crescimento lento que acomete principalmente adultos do sexo masculino na quinta década de vida. Ele normalmente afeta a região distal, com aparência polipoide. A aparência histológica é de uma massa dérmica sem cápsula,

6. Rare Case of Sarcomatoid Squamous Cell Carcinoma Arising in an Ovarian Mature Teratoma
Resumo Embora o teratoma cístico maduro (MCT) seja benigno, a transformação maligna (MT) ocorre em cerca de 1% a 2% dos casos, e geralmente apresenta-se sob a forma de carcinoma espinocelular (CEC), responsável por cerca de 80% dos casos. O carcinoma (sarcomatoide) de células fusiformes (CSCF) é um tipo incomum de CEC, compreendendo até 3% de todos os

7. Cholesteatoma and hydrocephalus associated to a third ventricle meningioma in a cat
RESUMO: Meningiomas são neoplasias que comumente envolvem o sistema nervoso central de gatos, enquanto colesteatomas são formações nodulares granulomatosas raramente descritas nessa espécie e que resultam de lesões crônicas em plexo coroide. O objetivo desse trabalho é descrever um caso de meningioma em terceiro ventrículo culminando com a formaç�

8. Scanning electron microscopy of dermatofibroma
Abstract: Dermatofibroma is a proliferation of spindle cells located in the dermis. We used scanning electron microscopy to examine two histologically confirmed lesions and observed preserved collagen bundles in the perilesional area. In the lesional area, the collagen was denser, without formation of bundles. Higher magnification showed collagen with mesh-l

9. PRIMARY LEIOMYOSARCOMA OF BONE: CLINICOPATHOLOGIC AND PROGNOSTIC FACTORS ANALYSIS IN A SINGLE INSTITUTION
RESUMO Objetivos: O leiomiossarcoma primário do osso (LPO) é um tumor ósseo maligno raro, considerado uma variante do sarcoma de células fusiformes (SCF). O objetivo deste estudo foi fazer uma análise clínico-patológica e dos fatores de prognóstico dos pacientes diagnosticados com LPO tratados em uma instituição única. Métodos: Foram analisados

10. Solitary fibrous tumor of the kidney: a report of two cases
RESUMO Tumor fibroso solitário (TFS) é uma neoplasia mesenquimatosa rara composta por células fusiformes monótonas, intercaladas por fibras de colágeno. Localização renal é incomum, com escassos casos descritos. Relatamos dois casos do gênero masculino, com 40 e 48 anos, um com detecção incidental de massa periférica; outro com lesão hilar desco

11. ENVIRONMENTAL VARIABLES AND QUALITY TOOLS APPLIED TO THE OPERATOR OF AN AGRICULTURAL MICROTRACTOR
ABSTRACT Work in the field is characterized as unstructured because it is performed in inconvenient postures, without a fixed workstation, exposing the worker directly to the sun and other inclement weather. This may interfere in the health and the performance of the activity. The objective of this work was to characterize the environment of the agricultural

12. Standardization and quality assessment for clinical grade mesenchymal stem cells from human adipose tissue
Abstract Background Mesenchymal stem cells have immense potential in stem cell-based therapies, however there is a pre-requisite to develop a curative cell dose. Adipose tissue-derived mesenchymal stem cells are promising mainly due to their potential abundance, immunomodulatory effect and remarkable differentiation potential. Nevertheless, senescence may d
