1. Pigmented eccrine poroma in an atypical location
Abstract Eccrine poroma is the term that includes benign neoplasms of the terminal duct of the eccrine sweat glands, which may clinically and dermoscopically resemble other melanoma and non-melanoma skin tumors. They are often located on the extremities (especially palms and soles), presenting as normochromic or erythematous papules and nodules, measuring up

4. Immunohistochemical analysis of FoxP3+ regulatory T cells in lower lip squamous cell carcinomas
Abstract: The aim of this study was to determine the number of FoxP3+ regulatory T (Treg) cells in the microenvironment of lower lip squamous cell carcinomas (LLSCCs) and to correlate the findings with clinicopathological parameters (tumor size/extent, regional lymph node metastasis, clinical stage, and histopathological grade of malignancy). Fifty cases of

5. Cellular neurothekeoma: case report and its (un) relation with nerve sheath myxoma
AbstractNeurothekeoma is an uncommon, benign neoplasm presenting in young adults, primarily on the head and neck. It was initially related to nerve sheath myxoma but with the advent of immunohistochemistry, new insights into its cellular differentiation and origin have emerged, unlinking Neurothekeoma and nerve sheath myxoma. Herein we describe a 19-year-old

7. Avaliação do endotélio da córnea de galinhas (Gallus gallus domesticus) em diferentes faixas etárias utilizando a microscopia especular
O endotélio corneano é uma monocamada de células poligonais localizadas na face posterior da córnea e é essencial para a manutenção da transparência corneana. Não foram encontradas referências na literatura a respeito dos parâmetros morfológicos e morfométricos do endotélio da córnea de galinhas, apesar destes animais serem amplamente utilizad

8. Caracterização da infecção por tripanossomatídeos (Protozoa: Kinetoplastida) presentes em três espécies de cascudo (Pisces: Loricariidae) do Rio Mogi-Guaçu, SP / Characterization of infection by Tripanossomatídeos (Protozoa: Kinetoplastida) present three species of armored catfish (Pisces: Loricariidae) from Mogi-Guaçu river, SP
Trypanosomes have been reported in several species of fish that inhabit salt and fresh waters. The majority of these protozoan species are described based on morphologic features. The parasites are heteroxenic and are transmitted by leeches. This work aims to characterize the prevalence and density of infection by Trypanosoma sp. present in the blood of thre

9. Evaluation of inverted papilloma and squamous cell carcinoma by nasal contact endoscopy / Avaliação por endoscopia de contato do papiloma invertido schneideriano e do carcinoma espinocelular nasossinusal
Background: Contact endoscopy (CE) was initially described as a method used in the analysis of uterine and vocal folds histology. The first nasal cavity CE studies achieved promising results regarding its use for the differentiation between benign and malignant lesions, considering that biopsy might cause some complications, especially bleeding. Objective: D

10. Characterization of Tyzzeria parvula (Kotlan, 1933) Klimes, 1963 oocysts (Apicomplexa: Eimeriidae) of the greylag goose (Anser anser Linnaeus, 1758) in Brazil. / Caracterização dos oocistos de Tyzzeria parvula (Kótlan, 1933) Klimes, 1963 (Apicomplexa: Eimeriidae) do ganso doméstico (Anser anser) no Brasil.
The principal objective of this research was to describe an coccidium found in the feces of greylag goose Anser anser Linnaeus, 1758. Based on morphometric analysis of these sporulated oocysts, they were classified as Tyzzeria parvula (Kótlan, 1933) Klimes, 1963. This coccidium was described for the firt time in goose of Brazil at rural and urban areas from

11. Individual risk prediction of node and distant metastasis based on lymphangiogenic intensity in typical pulmonary carcinoid tumor / Predição do risco individual de metástase linfática e hematogênica em função da intensidade da linfangiogênese no tumor carcinóide típico broncopulmonar
Typical pulmonary carcinoids are neuroendocrine cells proliferations and they were former considered lung adenomas with no hematogenic or lymphatic metastatic potential. However, it is known that up to 20% of patients develop metastatic disease. It is mandatory that new studies be developed due to the variation in clinical presentation of these patients. It

12. Elaboration of an Experimental Model of Pulmonary Carcinogenesis in Wistar Rats. / Elaboração de um modelo experimental de carcinogênese pulmonar em ratos wistar
The aim of this study was to elaborate an experimental model of pulmonary carcinogenesis in Wistar rats. So it was carried through an intra-pulmonary injection of the Benzo[a]pyrene (B[a]P) dilution in alcohol 70%, a polycyclic aromatic hydrocarbon widely known by its power of tumoral induction. After daily study accomplishment to verify the induced degree o
