21188 Background: Analysis of the cases of malignant lung tumors of young people (<34 yrs, born in 1963–2004) and diagnosed in 1997–2004 was made using the materials of the database of cancer registers of Volyn (V), Ivano-Frankivsk (IF), Lviv (L), Rivne (R), Ternopil (T) and Chernivtsi (C) regions. The population of young people <34 yrs of this region - 4.2 million/year. Results: Among 7541 cases of cancer in the six regions of the Western Ukraine malignant tumors of the lungs were diagnosed in 102 cases (1.4%). This pathology was registered in males in 57 cases, and in females in 45. The number of males with tumors of the lungs prevailed in V, IF, L, T. The number of young males and females with such pathology during the said period was the same - 11 cases in each gender group - in R. The youngest among the 102 individuals from the above said six regions were a boy aged 6 and a girl aged 16 from R. Combination with other tumors was observed in three females (C49, C53, C58) and one male (C81). In C among 766 cases of malignant tumors in young people <34 years lung cancer were detected in 5 (0.7%). Among 959 cases of cancer such tumors of the lungs were detected in 8 (0.8%) in V. Among the young people <34 years this pathology was detected in 14 (1.2%) in IF out of all 1156 cases of malignant tumors, in T - 947 tumor - 15 cases (1.6%). Among the six above regions in L there have been detected 2465 cases of malignant tumors, of which lung cancer were diagnosed in 38 - 1.5%. The highest frequency of occurrence of this pathology was registered in R (1.8%) - 22 cases in 1248 cases of malignant tumors. Conclusions: Fluctuation of frequency of this pathology in all these regions in various years during the investigated period had a wave-like character. As each of these regions is characterized by different geographic and climatic conditions, physical and chemical factors, exhausts of industrial enterprises, the study of frequency of malignant tumors in young people will permit to evaluated more objectively contribution of hereditary factor in the development of this pathology. The perspectives of further research in this field lie in the study of the role of genetic predisposition to the occurrence and development of malignant tumors in each patient, taking into account ecological zone of residence, occupational hazards and harmful habits. No significant financial relationships to disclose.

Introduction. Metastases to the oral cavity are uncommon, accounting for only 1% of all oral malignant tumors. When they occur they mostly originate from primary tumors of the lungs, kidney, breast and prostate. Oral metastases from the primary colorectal carcinoma are much more infrequent. Case Outline. We present an unusual case of a 78-year-old man with a soft tissue oral metastasis originating from the primary colorectal carcinoma. The patient was referred to the Department of Otorhinolaryngology, Head and Neck Surgery with an intraoral mass on the right side of the maxilla. The diagnosis was confirmed by histopathologic examination and immunohistochemical analysis. Conclusion. Oral metastases occur rarely and often can mimic much more common benign lesions, therefore they should be considered as a possibility in a differential diagnosis.

The female reproductive tract may be the site of a wide variety of benign and malignant tumors, as well as non-neoplastic tumor-like conditions, most of which can be diagnosed by light microscopic examination including special stains and more recently immunoperoxidase techniques. Nevertheless there are situations where ultrastructural examination can contribute substantially to an accurate and specific diagnosis. It is my opinion that electron microscopy can be of greatest benefit and is most cost effective when applied in conjunction with other methodologies. Thus, I have developed an approach which has proved useful for me and may have benefit for others. In cases where it is deemed of potential value, glutaraldehyde-fixed material is obtained at the time of frozen section or otherwise at operation. Coordination with the gynecologic oncologist is required in the latter situation. This material is processed and blocked and is available if a future need arises.

Testicular maldescent is the most common endocrine gland abnormality, as 2.7% of mature neonates are cryptorchid. The significant complications are that there is a disturbance of normal maturation which results in diminished fertility and there is an increase in the malignant potential which is 35 times greater in the undescended than the descended testis. It is considered that genetic influences may be of etiological importance and recurrence has been described in some families. It is of interest, that the case reported here has 2 siblings who have also presented with cryptorchidism and malignant tumors.The propositus is 14 years old. He is well developed (described by some as obese) and shows normal secondary male characteristics except for an immature scrotum. Laparotomy showed both testes to be intraabdominal. A hard nodule (0.5cm) was palpated on the medial aspect of the left testis. Frozen section showed the presence of seminoma and bilateral orchiectomy was performed.

In classical oncological literature two mechanisms for tissue aggression in patients with cancer have been described. The first is the progressive invasion, infiltration and destruction of tissues surrounding primary malignant tumor or their metastases; the other includes alterations produced in remote sites that are not directly affected by any focus of disease, the so called paraneoplastic phenomenon. The non-invaded tissue which surrounds a primary malignant tumor or its metastases has been usually considered a normal tissue . In this work we describe the ultrastructural changes observed in hepatocytes located next to metastases from diverse malignant tumors.Hepatic biopsies were obtained surgically in patients with different malignant tumors which metatastized in liver. Biopsies included tumor mass, the zone of macroscopic contact between the tumor and the surrounding tissue, and the tissue adjacent to the tumor but outside the macroscopic area of infiltration. The patients (n = 5), 36–75 years old, presented different tumors including rhabdomyosarcoma, leiomyosarcoma, pancreas carcinoma, biliar duct carcinoma and colon carcinoma. Tissue samples were processed with routine techniques for transmission electron microscopy and observed in a Hitachi H-500 electron microscope.
