PURPOSE To evaluate the characteristics of cataract changes in lens epithelial cells (LECs), in different types of human cataract. MATERIAL AND METHODS Anterior capsules for the study were obtained from patients with different types of cataracts during extracapsular cataract extraction, or phacoemulsification using continuous curvilinear capsulorhexis.(More)
OBJECTIVES The aim of the study was to demonstrate and evaluate the expression of cyclin D1, a protein connected with a cell cycle, by means of the immunohistochemical method in malignant thyroid neoplasms. The purpose of the analysis of the results was to explain the relation between cyclin D1 in thyroid cells and neoplasm transformation. MATERIAL AND(More)
Calcifying fibrous tumour (CFT) is a benign tumour of elusive aetiology and a potential for local recurrence. Despite its peculiar histological characteristics it can still be confused with interrelated differential diagnosis like inflammatory myofibroblastic tumour (IMT) or solitary fibrous tumours. The clinical differential diagnosis is however much(More)
Malignant degeneration within epidermal cysts is very rare. However, these lesions may not be recognised clinically, and histological examination plays an important role in arriving at a correct diagnosis. Hence, we believe that benign-looking cystic lesions with a history of progressive growth should be surgically excised and submitted for(More)
A case of the respiratory epithelial adenomatoid hamartoma of the nasal cavity, maxillary sinus and ethmoid sinuses for the first time in the polish literature was reported. Characteristic clinical symptoms and histopathologic features, diagnosis and surgical intervention as well differential diagnosis were introduced.
BACKGROUND Nasal angiofibromas are commonly called juvenile nasal angiofibromas (JNA) because of the almost exclusive occurrence in adolescent males. It is a relatively rare benign fibrovascular tumor originating in the posterior lateral wall of the nasopharynx with only a very few cases diagnosed in females. CASE REPORT Authors present a case of a 26(More)
PURPOSE In our research we investigated immunohistochemical expression of cell cycle proteins protein p21, cyclin D1 and cyclin E in physiological endometrium (n = 15), hyperplastic endometrium (n = 61), and post hormone replacement therapy endometrium (n = 24). MATERIAL AND METHODS We performed immunohistochemical analysis of selected cell cycle proteins(More)
