Porous biosilica nanoparticles obtained from diatomites (DNPs) have been recently demonstrated to be non-toxic nanovectors of therapeutic agents in cancer cells. In this work, the internalization kinetics and intracellular spatial distribution of functionalized DNPs incubated with human lung epidermoid carcinoma cell line (H1355) up to 72 h are investigated by Raman imaging. The label-free Raman results are compared with confocal fluorescence microscopy and photoluminescence (PL) data. Raman bands specifically assigned to DNPs and cellular components provide evidence that the nanovectors are internalized and co-localize with lipid environments...

CLINICAL PROBLEM: Intracerebral cysts are common findings in imaging of the neurocranium and are not always clinically significant. The pathological spectrum of intracerebral cysts is, however, very broad and in addition to incidental findings includes developmental disorders, malformation tumors, primary and secondary neoplasms and infectious etiologies, such as cerebral abscess formation, cysticercosis or residuals after congenital cytomegalovirus infections. Intracerebral cystic defects may be caused by inflammatory central nervous system (CNS) diseases, such as multiple sclerosis as well as by mitochondriopathies, leukodystrophy, electrolyte disturbances or osmotic demyelination syndrome or brain infarctions, e...

Central mucoepidermoid carcinoma (MEC) poses a diagnostic challenge because of its rarity and histological overlap with glandular odontogenic cyst (GOC). In MEC of both salivary glands and jaws, MAML2 arrangement has been well known as the specific gene alteration. We report a case of central MEC arising from GOC diagnosed by MAML2 fusion gene. A 57-year-old male presented a multilocular cystic lesion in left molar region of the mandible. Histopathologically, multiple cysts lined by thin cuboidal or non-keratinized squamous epithelium with small duct-like structures, mucous cells and ciliated cells were present...

We report two cases of pathologically proven intracranial epidermoid cysts. Both cases were scanned with diffusion-weighted imaging using pulsed gradient spin-echo (PGSE) and oscillating gradient spin-echo (OGSE; 50 Hz) prototype sequences with diffusion times of 47.3 ms and 8.5 ms, respectively. The apparent diffusion coefficient measured by OGSE was higher than that measured by PGSE, indicating the spatial restriction of water diffusion in the laminated keratin layers within the cyst as demonstrated by histopathology...

In this work, a novel drug delivery system consisting of poly(ε-caprolactone) (PCL) electrospun fibers containing an ad-hoc-synthesized star polymer made up of a poly(amido-amine) (PAMAM) core and PCL branches (PAMAM-PCL) was developed. The latter system which was synthesized via the ring opening polymerization of ε-caprolactone, starting from a hydroxyl-terminated PAMAM dendrimer and characterized by means of (1)H NMR, IR and DSC, was found to be compatible with both the polymer matrix and a hydrophilic chemotherapeutic drug, doxorubicin (DOXO), the model drug used in this work...

Trichofolliculoma (TF) is a hamartomatous hair follicle-related tumor, clinically described as a dome-shaped papule with a central pore crossed by one or more silky white hairs. Histologically, it described as a cystic cavity containing keratinous debris, hair shaft fragments, and numerous hair follicles arising from its linings. Collision or compound tumors are a coexistence of two or more identifiable tumors in the same lesion. We present a case of a 47-year-old man with a lesion on his left cheek clinically characterized as a TF...

The patients presenting with lump in inguinal area are mostly suspected as hernias. Epidermoid cyst commonly presenting in head and neck region rarely may develop from inguinal canal structures. We present here a rare case of epidermoid cyst measuring 7×8 cm as a content of inguinal canal diagnosed by ultrasonography. Surgical excision was done and confirmed as epidermoid cyst by histopathology. We conclude that cutaneous cysts in inguinal area may be a presentation and should be kept in mind for differential diagnosis...

Multidrug resistance (MDR) is one of major obstacles to effective chemotherapeutic treatment of cancer. This study showed that DHPAC, 2-(6-ethoxy-3-(3-ethoxyphenylamino) -1-methyl-1,4-dihydroindeno[1,2-c]pyrazol-7-yloxy) acetamide, a novel compound that binds to the same site on microtubules as colchicine, has high anti-tumour activity in vincristine-resistant oral epidermoid carcinoma (KB/V) cells. It found that the presence of DHPAC strongly inhibited KB/V cell growth in vivo and in mice xenograft. The inhibitory effect of DHPAC is much stronger than that by colchicine in these KB/V cells (IC50: 64...

This article reports a case of a cerebellopontine angle epidermoid cyst presenting as isolated painful trigeminal neuropathy. The indolent nature of these uncommon benign tumors leads to frequent delays in their presentation and diagnosis, with patients often initially undergoing dental procedures. This is illustrated in the present case reported here, which highlights the difficulties in identifying trigeminal neuralgia (TN), particularly in its early phases, and supports current recommendations for routine neuroimaging in suspected cases of painful trigeminal neuropathy, which, unlike classic TN, is caused by a disorder other than neurovascular compression (even in the absence of additional neurologic symptoms or signs) and is present particularly in younger patients with atypical features...

To date, epidermoid cysts associated with human papillomavirus (HPV) infection have been described mainly in palmoplantar locations, and have involved HPV types 60 and 57. In contrast, HPV-6/11 is a major cause of condyloma acuminatum. Here, we report the case of a healthy 31-year-old man who presented to our clinic with a 1-month history of a 1-cm, reddish-brown, cystic scrotal tumor with a punctum. The lesion was studied histologically, immunohistochemically and by DNA-DNAin situ hybridization. Histology revealed an epidermoid cyst with vacuolated keratinocytes with shrunken nuclei (koilocytes) in the cyst wall...

BACKGROUND: Advanced stage cancer treatments are often invasive and painful-typically comprised of surgery, chemotherapy, and/or radiation treatment. Low transport efficiency during systemic chemotherapy may require high chemotherapeutic doses to effectively target cancerous tissue, resulting in systemic toxicity. Nanotherapeutic platforms have been proposed as an alternative to more safely and effectively deliver therapeutic agents directly to tumor sites. However, cellular internalization and tumor penetration are often diametrically opposed, with limited access to tumor regions distal from vasculature, due to irregular tissue morphologies...

The incidence of female urethral cancer is rare and accounts for 0.02% of all women's cancers. It is dominated by epidermoid carcinoma, which most commonly develops in the distal portion of the urethra, extending to inguinal lymph nodes. The diagnosis is confirmed in the distal forms on the basis of uretrocystoscopy with biopsy. Abdominopelvic MRI allows to determine tumor extension as well as its infiltration into tissues and peri-urethral organs. As in superficial tumors of the distal urethra, simple circumferential resection of the urethra associated with resection of the adjacent portion of the anterior surface of the vagina is sufficient...
