we present a case of allergic fungal sinusitis (afb) in a 20-year old man with few months' history of bilateral nasal obstruction and discharge with unilateral proptosis that underwent maxillary antrostomy due to the mass in paranasal sinuses. histological examination of tissue showed branching fungal hyphae interspersed with allergic mucin without fungal invasion to soft tissue. the patient re...

introduction rhino-orbito-cerebral mucormycosis is a progressive angioinvasive fungal disorder which almost always complicates immunocompromised patients. case presentation we described a case of fulminant rhino-orbito-cerebral mucormycosis in a 65-year-old woman, who presented with progressive neurological deficits due to involvement of orbital apex and the central nervous system by local inva...

BACKGROUND Treatment of oral cavity cancer may require variable extent of mandibular resection. Marginal mandibulectomy is a controversial technique in providing oncologic resection margin. This study analyzes the efficacy of local oncologic control and the morbidity of marginal mandibulectomy in oral cavity carcinoma. Nononcologic complication of osteoradionecrosis is discussed. METHODS A re...

Local and distant tumor spread was evaluated and compared with DNA content analyzed by flow cytometry of eight samples from each of 71 renal cell carcinomas. Twenty-six tumors were homogenously diploid while 45 tumors contained at least one aneuploid tumor sample. Diploid tumors generally respected the surrounding tissues and only three of 26 tumors (12%) had evidence of local tumor invasion. I...

Pilomatrix carcinoma originates in the matrix cell and is marked by exophytic growing and common local recurrence. There is no established treatment for wide local invasion and metastasis of the pilomatrix besides wide surgical resection. We report a case of rapidly progressive pilomatrix carcinoma, which arose around an Eloesser open window with direct invasion to the adjacent tissue.

The pH of solid tumors is acidic due to increased fermentative metabolism and poor perfusion. It has been hypothesized that acid pH promotes local invasive growth and metastasis. The hypothesis that acid mediates invasion proposes that Hþ diffuses from the proximal tumor microenvironment into adjacent normal tissues where it causes tissue remodeling that permits local invasion. In the current w...

this report provides the first record of the exotic sucker fish p. pardalis from the cauvery river system, tamilnadu state, india. information on the assumed presence of this invasive species based on sightings of a hitherto unknown species by local people and fishermen in stretches of cauvery river have been confirmed by our study. sailfin sucker fishes are popular among pet traders and aquari...

The pH of solid tumors is acidic due to increased fermentative metabolism and poor perfusion. It has been hypothesized that acid pH promotes local invasive growth and metastasis. The hypothesis that acid mediates invasion proposes that H(+) diffuses from the proximal tumor microenvironment into adjacent normal tissues where it causes tissue remodeling that permits local invasion. In the current...

Background: Proliferating trichilemmal tumors are slow-growing lobulated masses most commonly found on the scalp of elderly women. Due to the locally invasive nature of the lesion, the treatment is complete excision of the tumor with tumor-free margins. Methods: We present two cases of trichilemmal tumors that exhibited aggressive local invasion across tissue planes. The first case had dural in...
