Os angioceratomas são tumores benignos caracterizados por ectasia dos vasos sanguíneos da derme papilar associada à acantose e hiperceratose epiderme. Ao exame dermatológico, os de Fordyce caracterizam-se lesões papulo-ceratóticas coloração eritemato-violácea. São mais comuns no escroto, sendo raramente relatada a localização vulvar. A histopatologia é particularmente importante para difer enciá-los outros malignos. O artigo relata o caso uma mulher negra meia idade com história obstipação...
Background Chronic telogen effluvium (CTE), a poorly understood condition, can be confused with or may prodrome to female pattern hair loss (FPHL). The pathogenesis of both is related follicle cycle shortening and possibly blood supply changes. Aim To analyze number histomorphometric immunohistochemical findings through vascular endothelial growth factor (VEGF), Ki-67, CD31 immunostaining in scalp biopsies 20 patients CTE, 17 mild FPHL 9 controls. Methods Ki-67 index VEGF optical density...
Cryosurgery is an efficient therapeutic technique used to treat benign and malignant cutaneous diseases. The primary active mechanism of cryosurgery related vascular effects on treated tissue. After a cryosurgical procedure, exuberant granulation tissue formed at the injection site, probably as result angiogenic stimulation cryogen inflammatory response, particularly in endothelial cells.To evaluate freezing, part phenomenon healing rat skin subjected previous injury.Two incisions were made...
Sarcoidosis and tuberculoid leprosy (TL) are prototypes of granulomatous inflammation in dermatology, which embody one the histopathology limitations distinguishing some diseases. Recent advances use nonlinear optical microscopy skin have enabled techniques, such as second-harmonic generation (SHG), to become powerful tools study physical biochemical properties skin. We SHG images analyze collagen network, distinguish differences between sarcoidosis TL granulomas. obtained from biopsies 33...
Human bartonelloses are a group of illnesses poorly understood pathogenesis. Bartonella henselae is one the most studied bacterium its genus. The objective this study was to observe whether passages these bacteria, in vivo, would determine ultrastructural changes them. For purpose, isogenic mice were inoculated with standard strain B. (I). These initially retrieved from genetically immunodeficient animals (II) and then immunocompetent ones. bacterial colonies obtained (III) compared, by...
Background: Mercury poisoning presents a variety of clinical pictures depending on chemical structure, amount absorbed, total mercury burden, and individual factors. Distant skin lesions, after subcutaneous injection metallic mercury, have not been previously described. Case Report: We present homicidal, resulting in widespread remote from the radiologically visible mercury. The lesions appeared at 40 days began to clear 6 months injection.
Background Immunosuppression is the leading cause of recurrent sinus infections after hematopoietic stem cell transplant (HSCT), with increased incidence sinusitis in patients chronic graft versus host disease (GVHD). Histological descriptions oral mucosa, lung ciliary epithelium, and intestinal mucosa related to HSCT have been described. However, few described nasal mucosa. We, therefore, sought elucidate histological ultrastructural features better understand pathophysiology immune...
Abstract Background The distinction between chronic telogen effluvium ( CTE ) and female pattern hair loss FPHL is important because of their different prognosis treatment. Non‐invasive methods have been described to be useful in differentiating from . This prospective study investigated the use washing method differentiate mild Methods Twenty patients with 17 were recruited followed for 18 months. diagnosis was established through clinical, laboratory, histological studies. asked abstain 5...
Abstract Solid tumors typically contain high levels of fibrillar collagen. The increased stromal collagen deposition usually promotes cancer progression since biochemical and biophysical cues from tumor-associated fibers stimulate neoplastic cells. Few studies have investigated the relationship between Merkel cell carcinoma (MCC) extracellular matrix (ECM), but there are no works evaluating This is an observational, analytical, retrospective study including 11 patients with MCC. Primary...
CONTEXT: Struma ovarii, a rare neoplasm, is monophyletic teratoma composed of thyroid tissue. It generally considered to account for less than 5% mature teratomas. CASE REPORT: A diagnosis struma ovarii may be the source many diagnostic problems. cystic and microscopic examination only reveal few typical follicles, resulting in confusion with other ovarian tumors. Extensive sampling should undertaken immunohistochemistry decisive establishing nature epithelial lining. The authors report two...
Pigmented lesions of the oral mucosa encompass several benign and malignant conditions that may be a matter concern under both clinical histopathological views. We reported case 62-year-old woman, presenting with an asymptomatic, deeply pigmented lesion on soft palate. On examination, it appeared asymmetrical, irregular borders area ulceration. A biopsy, taken to rule out melanoma, revealed carcinoma in situ. Throughout tumor thickness, numerous interspersed melanocytes were found did not...
