Introduction: In the past enucleation was the treatment of choice for all the patients with uveal melanoma. Nowadays, we prefer glope-sparing treatment modalities, except for large tumors, tumors with extrascleral extension and painful blind eyes. Most of the patients perform radiotherapy or local resection techniques. In Slovak Republic, the only one possibility is a stereotactic radiotherapy on a linear accelerator LINAC. Nevertheless, enucleation after radiotherapy is necessary for some patients. The causes are postradiation complications, mainly neovascular glaucoma, tumor recurrence, tumor progression or patient´s decision. Material and methods: The retrospective non-randomised study of 168 eyes of the patients with choroidal or ciliary body melanoma, who performed one-day session stereotactic radiosurgery at the linear accelerator LINAC during period 2007-2016. The data about postradiation complications were analysed based on the medical records of the patients and the data about enucleated eyes based on the histopathological findings. Results: The occurence of enucleation after radiotherapy in our cohort was 17 % (28 patients), with median time period after radiotherapy 21,5 months. The most common cause was neovascular glaucoma (82 %), then tumor progression (14 %) and patient´s decision (4 %). The most common histopathological finding was spindle-cell melanoma. Discussion: Others authors describe similar enucleation rate and causes. The histopathological findings indentified more viable melanoma cells in eyes enucleated for tumor progression in comparison with enucleation for other causes. Enucleation may be more difficult and the occurence of postoperative complications can be higher in the eyes after radiotherapy rather than primary enucleation. Conclusion: The management of the patients with uveal melanoma is difficult, and requires the cooperation of ophthalmologist, oncologist, radiation physicist and pathologist. Even if we make effort to preserve the eye, enucleation after radiotherapy is necessary in some patients.

Histopathological Findings

It has been shown in previous studies that the toxin T-514 isolated from K. humboldtiana induces severe damage to the lung in treated rodents. Histopathological findings include edema, and alveolar hemorrage. However, the ultraestructure of the lesion has not been investigated. In this study we used two species of rodents: Hamster and guinea pig, and a primate: Macaca fascicularis. Animals received different single dosis of the toxin via intraperitoneal. Control animals received only the vehicle (propylen glycol). Inmediately after spontaneous death, lung samples were fixed in Karnovsky-Ito fixative, post fixed in osmium tetroxide and embedded in epon. Thin sections were prepared with an Ultratome V LKB, stained with uranly acetate and lead citrate, and studied in an electron microscope Zeiss-EM109.

A Prospective Study

Background: A breast lump is the most common symptom associated with both benign and malignant breast diseases. Therefore, a distinction of benign from malignant lump is of importance for proper management. Though a definitive diagnosis is possible with imaging for all the lesions, histopathological study is proven essential for confirming the diagnosis. Objective: The objective of this study was to evaluate the role of USG and histopathological findings of different breast lump in diagnosis and their comparison. Methods: A prospective study was conducted over a period of one year from January 2017 to December 2017. A total of 116 patients were included in this study. All breast lumps underwent surgery and the ultrasound findings of these lumps were compared with the histopathological findings. Data were collected from these patients by a preformed questionnaire and finally the data were analyzed. Results: Out of 116 patients only 21 cases were reported as malignant in ultrasound report but histopathology revealed 31 malignant patients. On histopathological examination 10 benign cases turned out to be malignant. Conclusion: The present study was undertaken to evaluate in diagnosing breast mass lesions individually by ultrasound and compared with histopathology for definitive management of a patient.
