AIMS To investigate the smooth muscle nature of the spindle stromal cells in the capsule of thyroid tumours and tumour-like lesions. METHODS Immunostaining for high molecular weight caldesmon (HCD), a highly specific marker for smooth muscle differentiation, was performed in 70 primary thyroid tumours and tumour-like lesions (21 hyperplastic nodules, 29 follicular adenomas, five minimally inv...

Tamoxifen is a widely used in anti-oestrogen treatment of breast cancer. Previous reports showed that tamoxifen is associated with proliferative endometrial lesions. We herein reported an unusual case of concurrent hyperplastic lesions in the uterine cavity and right ovary in a 45-year-old woman with tamoxifen therapy. Regular vaginal ultrasonography showed the progressive endometrial thickenin...

 Abstract Reactive soft tissue lesions are common in the oral cavity. These lesions usually occur as a painless non-neoplastic proliferation. Surgical excision of these lesions will cause aesthetic and mucogingival problems in the area. In this case, a prominent lesion in the anterior maxilla of a 40-year-old woman had recurred after two years. Surgical treatment was performed with complete ...

OBJECTIVE Podoplanin, a known lymphatic endothelial cell marker, has been reported to be expressed in various types of cancer. To elucidate the expression of podoplanin in precancerous lesions, we examined the immunohistochemical profiles of podoplanin in oral squamous epithelial lesions. METHOD We studied a total of 298 foci of squamous cell carcinoma (SCC), carcinoma in situ (CIS), epitheli...

The purpose of this study is to identify colorectal serrated lesions in the inflammatory mucosa of inflammatory bowel disease (IBD), to characterize their molecular status based on BRAF and KRAS mutations, mismatch-repair (MMR) deficiency and microsatellite instability (MSI), and to verify that these molecular alterations are specific to the 'serrated neoplasia pathway' in IBD. Neoplastic lesio...

OBJECTIVES To determine if there are differences in the expressions of the E-cadherin adhesion molecule of precancerous laryngeal lesions classified according to Ljubljana and World Health Organization (WHO) classification. PATIENTS AND METHODS We examined 41 cases (3 females, 38 males; mean age 54 years; range 8 to 80 years) of laryngeal hyperplastic-dysplastic lesions from the Kocaeli Unive...

Rhinosporidiosis is an inflammatory disease caused by Rhinosporidium seeberi, a protoctistan mesomycetozoa, member of a group of novel aquatic parasites, characterized by hyperplastic polypoid lesions of the nasal cavity and rarely other mucous membranes. We report an unusual presentation of rhinosporidiosis as an urethral polyp, which is only the second case of rhinosporidiosis reported from P...
