In this paper we presented a patient with a very rare form of pancreatic tumour. The disease began with very non-specific abdominal pain, loss of appetite, and vomiting, mostly mucus. Proximal endoscopy was performed which revealed hiatal hernia and ulcer in the duodenum. Computed tomography of the abdomen showed a tumour formation in the tail of the pancreas, which was surgically removed. Histopathological verification confirmed that it was a solid pseudopapillary tumour of the pancreas. The patient is on regular oncological control.

Carcinoma of unknown origin is defined as the absence of primary tumor and biopsy proved the existence of metastatic changes. The incidence is about 3% of all cancers. We present a case of a patient who underwent surgery for left breast mammography verified pathological lymphonodes on the left breast and on the left axillary region. Histopathological analysis of excised tissue showed the absence of malignant disease in the breast. A complete diagnostic evaluation also did not confirm the primary lesion. We done fluorodeoxyglucosa positron emission tomography, which had set suspicion of primary breast cancer, but biopsy and pathological reverification were not confirmed. The patient spent six cycles of chemotherapy for cancer of unknown origin. After a year and six months because of sudden right side hemiparesis were performed Computed Tomography and Magnetic Resonance imaging of the head, which indicated that it was a metastatic brain tumour. After metastasectomy, histopathological finding was finally proved to be a metastasis of breast adenocarcinomas. The patient had irradiation of the cranium, and began chemotherapy protocol for breast cancer. In this case, insufficient diagnosis did not affect in the proper therapeutic approach.

Spontaneous regression of herniated nucleus pulposus occurs when intervertebral disc herniation loses its volume partly or totally without surgical interventions. Cases of spontaneous regression of large extruded lumbar disc are rare. We presented a patient with large lumbar disc extrusion documented by Magnetic Resonance Imaging, but not found intraoperatively four months after performing diagnostic. Postoperatively he felt well for two months when the pain reappeared. Control Magnetic Resonance of lumbar spine showed complete resolution of extruded disc fragment comparing with the initial Magnetic Resonance Imaging.
