Squamous cell carcinoma of thyroid is an uncommon, very aggressive neoplasm, having a poor prognosis and poor response to chemotherapy and radiotherapy. Surgery is the initial treatment of choice, although it often presents as a widespread disease at the time of diagnosis, usually with cervical swelling that causes most of the symptoms due to local infiltration or metastasis. Local infiltration from adjacent tumour and metastatic disease needs to be excluded from other primary epidermoid carcinomas, in order to make a correct diagnosis...

The heterocyclic amine 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) targets multiple organs for tumorigenesis in the rat, including the colon and the skin. PhIP-induced skin tumors were subjected to mutation screening, which identified genetic changes in Hras (7/40, 17.5%) and Tp53 (2/40, 5%), but not in Ctnnb1, a commonly mutated gene in PhIP-induced colon tumors. Despite the absence of Ctnnb1 mutations, β-catenin was overexpressed in nuclear and plasma membrane fractions from PhIP-induced skin tumors, coinciding with loss of p120-catenin from the plasma membrane, and the appearance of multiple p120-catenin-associated bands in the nuclear extracts...

BACKGROUND: Although treatment of localized anal cancer (AC) is well established, very little evidence is available to inform the management of advanced tumors, and the prognosis of these patients remains poor. We have analyzed treatment pathways and outcomes of a single-institution series of advanced AC patients in order to provide insight into the management of this rare condition. MATERIALS AND METHODS: Inclusion criteria included epidermoid histology, inoperable locally recurrent or metastatic disease, and availability of full medical records...

Multiplex staining of cell and tissue sections with antibodies raised in the same host species is a serious challenge because of unwanted but inevitable cross-reactivity of secondary antibodies with irrelevant primary antibodies. Several techniques can be used to overcome this obstacle including direct labeling of primary antibodies with fluorescent tags and using tyramide signal amplification. Unfortunately these techniques either lack sensitivity, or require a long multistep protocol which can cause physical damage of specimens...

Intraosseous epidermoid cysts are exceedingly rare. Known as pseudotumors, not true neoplasms, intraosseous epidermoid cysts usually involve the phalanges, the skull, and the toes. Intraosseous epidermoid cysts typically present as destructive osteolytic lesions on X-ray, mimicking malignant bone tumors. Here, we present two cases of an intraosseous epidermoid cyst in the distal phalanx treated with curettage and synthetic bone graft, followed by a review of the relevant literature. In both cases, the patient presented with a painful enlargement of the fingertip following a minor trauma...

INTRODUCTION AND OBJECTIVES: Dysphonia is a common problem in children, especially those of school age. Exploration of vocal folds is often difficult and less accurate in children. The most frequent lesions found in children with chronic dysphonia are vocal nodules, followed by epidermoid cysts and other congenital lesions, such as sulci and mucosal bridges. The treatment is multidisciplinary and it is fundamentally based on vocal rehabilitation. We indicate surgical treatment in children older than 9 years of age for whom the problem persists after rehabilitation, especially if we suspect a congenital lesion of the vocal fold...

The study of the chemical constituents of branches and twigs of Cratoxylum cochinchinense collected in Singapore led to the isolation and structural elucidation of four new xanthones, named cratoxanthone A (1), B (2), C (3), and D (4), together with six known xanthones (5-10) and one known dihydroanthracenone (11). Eight xanthones (including 1 and 2) and 11 were tested for their antiproliferative activity in three human carcinoma cell lines (lung adenocarcinoma A549, colorectal carcinoma Colo205, and epidermoid carcinoma KB) and a human acute lymphoblastic leukemia B cell line (NALM-6), and the mitochondrial membrane potential was determined in KB cells...

OBJECTIVE: The aim of this study was to develop a rapid diffusion-weighted (DW) magnetic resonance imaging (MRI) technique for whole-brain studies without susceptibility artifacts and measuring times below 3 minutes. MATERIALS AND METHODS: The proposed method combines a DW spin-echo module with a single-shot stimulated echo acquisition mode MRI sequence. Previous deficiencies in image quality due to limited signal-to-noise ratio are compensated for (1) by radial undersampling to enhance the flip angle and thus the signal strength of stimulated echoes; (2) by defining the image reconstruction as a nonlinear inverse problem, which is solved by the iteratively regularized Gauss-Newton method; and (3) by denoising with use of a modified nonlocal means filter...

INTRODUCTION: Retrorectal cysts are rare benign lesions which are frequently diagnosed in middle-aged females. According to their origin and histopathologic features, retrorectal cysts are classified as squamous-lined (dermoid or epidermoid) cysts, postanal gut (tailgut) cysts, and rectal duplications (enteric or enterogenous cysts, enterocystomas). Described in this case report is an extremely unusual patient, a woman who simultaneously had a retrorectal cyst and an ovarian serous cystadenoma in addition to a long history of misdiagnosis and multiple unsuccessful surgeries...

To investigate the characteristics of symptomatic trigeminal neuralgia (TN) caused by tumors and the relationship between anatomicosurgical findings and tumor type, the authors undertook a retrospective review of 35 patients with symptomatic TN between 2006 and 2015. The tumors included 16 meningiomas, 14 epidermoids, 4 vestibular schwannomas, and 1 hemangioblastoma. The studies show that patients with tumor-induced TN were significantly younger than those idiopathic TN (P <0.05). Meningioma-induced TN tended to have responsible vessels, while epidermoid tumor seemed to cause TN by wrapping or compressing the nerve...

Superficial angiomyxomas (SAMs) are rare benign cutaneous tumors that involve the subcutaneous layer. They are commonly located in the trunk, lower limbs and head or neck of women of reproductive age. SAMs in the vulva of postmenopausal women are especially rare case. Herein, we report a vulvar SAM in a postmenopausal 60-year-old woman. The patient presented with a palpable cutaneous mass in the right labium majora that had appeared 3 months earlier. The mass was slow growing and approximately 5 cm in size and resembled a soft tissue malignancy...

A 71-year-old woman, previously treated for malignant lymphoma, was admitted to our hospital with a tumor in the right breast. The tumor size was 2.0 cm in diameter, and the borderline was unclear. The core needle biopsy material revealed an invasive adenocarcinoma with metaplastic change. Right mastectomy and sentinel lymph node biopsy was performed. Histologically, the tumor was composed of mucus-secreting, epidermoid, and intermediate cells. These findings confirmed the diagnosis as mucoepidermoid carcinoma (MEC) of the breast...
