Clinical, dermoscopic, and histologic aspects of two cases of cutaneous focal mucinosis

An. bras. dermatol; 94 (3), 2019
Abstract: Cutaneous mucinoses are a complex and diverse group of connective tissue disorders characterized by the accumulation of mucin and/or glycosaminoglycan in the skin and adnexa. Cutaneous focal mucinosis appears as a solitary, asymptomatic, skin-colored to white papule, nodule, or plaque located a...

Is the colon mucosa affected by ten days of gastric restriction in an animal model?

Acta cir. bras; 34 (6), 2019
Abstract Purpose To identify whether the colon mucosa is affected by ten days of gastric restriction in an animal model. Methods An experimental model of gastric restriction was devised using rats. The animals were submitted to surgical gastrostomy, and a cylindrical loofah was inserted into the stom...

Enemas with mesalazine increase the tissue contents of mucins in the colonic mucosa devoid of fecal stream

Acta cir. bras; 34 (4), 2019
Abstract Purpose: To evaluate the inflammatory reaction and measure the content of mucins, in the colonic mucosa without fecal stream submit to intervention with mesalazine. Methods: Twenty-four rats were submitted to a left colostomy and a distal mucous fistula and divided into two groups according t...

Scanning electron microscopy of granuloma annulare

An. bras. dermatol; 93 (5), 2018
Abstract: Light microscopy of granuloma annulare shows mucin deposition with lympho-histiocytic infiltrate. We describe the ultrastructural three-dimensional aspects of a typical case of granuloma with characteristic histopathological findings. At the ultrastructural level, affected collagen bundles and ...

Caracterização dos fenótipos de mucina podem prever a recorrência do câncer gástrico precoce após a mucosectomia endoscópica

Arq. gastroenterol; 54 (4), 2017
ABSTRACT BACKGROUND: Endoscopic mucosal resection is still considered an accepted treatment for early gastric cancer for selected cases. Histopathologic criteria for curative endoscopic resection are intramucosal well-differentiated adenocarcinoma, lateral and deep margins free of tumor, no histological...

Influence of the application of enemas with oily extract of curcumin (Curcuma longa) on the tissue content of neutral and acidic mucins in the colonic mucosa without fecal stream

ABSTRACT Purpose: To verify if the application of enemas containing oily extracts of curcumin preserves the tissue content of mucins in the glands of the colonic mucosa without fecal stream. Method: Thirty-six Wistar rats were submitted to diversion of the fecal stream by proximal colostomy and distal ...

Tissue sulfomucin and sialomucin content in colon mucosa without intestinal transit subjected to intervention with Curcuma longa (curcumin)

Acta cir. bras; 32 (3), 2017
Abstract Purpose: To measure the tissue sulfomucin and sialomucin content of the colon mucosa without fecal flow, subjected to intervention with curcumin, and the influence of the concentration used and the intervention time. Methods: Thirty-six rats were subjected to proximal right colostomy and dis...

Case for diagnosis. Lichen myxedematosus

An. bras. dermatol; 91 (6), 2016
Abstract Scleromyxedema or lichen myxedematosus is a rare papular mucinosis of chronic and progressive course and unknown etiology. It is commonly associated with monoclonal gammopathy and may show extracutaneous manifestations, affecting the heart, lung, kidney, and nerves. The diagnosis is based on fou...

Number of lymph nodes dissected in colorectal cancer and probability of positive nodes, angiolymphatic/perineural invasion, and intracellular mucin in a referral service

Among the malignancies, colorectal cancer ranks fourth in incidence in Brazil. The main prognostic measure is related to the amount of affected lymph nodes. Thus, many studies try to correlate the number of extracted lymph nodes, with the probability of obtaining positive nodes. Study objectives: Determ...

Lupus tumidus: a report of two cases

An. bras. dermatol; 91 (5,supl.1), 2016
Abstract Lupus tumidus is considered a rare subtype of chronic cutaneous lupus erythematosus, characterized by erythema and bright urticarial erythematous-violaceous lesions that leave no scars after regression. Histopathology reveals perivascular and periannexal lymphohistiocytic infiltrates in the papi...
