Calcifiyng fibrous pseudotumor (CFPT) is a benign mesenchymal tumor diagnosed in children and young adults, located in the subcutaneous tissue of the trunk and limbs. Its intraabdominal localization is a unique rarity. The Authors of the study presented a case of a 48-year old female patient with an accidentally diagnosed small bowel mesentery tumor during surgery

Introduction: The fourth edition of the WHO Classification of Tumours of the Urinary System and Male Genital Organs (2016) contains new renal tumour entities. These new subtypes of renal cell carcinoma (RCC) were introduced based on morphological criteria, some genetic features, and clinical characteristics with prognostic implications. We present three patients with rare renal tumours belonging to newly recognized or still emerging categories of RCC. All cases were diagnosed based on careful morphological examination with immunophenotyping, and patho- clinical correlation. The first case is an example of acquired cystic disease - associated renal cell carcinoma with heterogeneous architecture as well as specific intra- and intercytoplasmic microlumens. The second tumour - a tubulocystic renal cell carcinoma - was composed of multiple, various-sized cysts divided by fibrovascular septa and tubules lined focally with hobnail cells. The third case presents very rare sporadic eosinophilic, solid, and cystic RCC. This tumour contained macro et microcystic, areas intermixed with solid fields composed of large, in part multinucleated eosinophilic cells. Inflammatory infiltrations accompanied the neoplastic stroma. New subtypes of RCC, although rare, can be encountered in everyday practice. It is important to perform careful differential diagnosis and classify such tumours according to the recent guidelines.

Two cases of intraspinal thoracolumbar tumours with meningeal involvement in boys aged 10.5 and 12 years are presented. Medical history of both patients comprised headaches and back pains lasting for some weeks and months before admission. Because of the significant extension of the neoplastic process, one patient was disqualified from tumour resection and was administered with neoadjuvant chemotherapy. The second patient received partial tumour resection and supplementary intense chemotherapy. Both children died of disease progression after 2 and 15 months after first symptoms occurrence, respectively. Autopsy revealed malignant gliomas with extensive meningeal involvement as well as neoplasm dissemination within central nervous system via cerebro-spinal fluid in both cases. Vertebral pain is a rare neurological symptom in children, requiring particular attention and thorough radiological examination. It needs to be stressed that headaches may be also the first symptom of the tumour located within vertebral column.

Przedstawiamy dwa przypadki guzów śródrdzeniowych odcinka piersiowo-lędźwiowego z towarzyszącym zajęciem opon mózgowo-rdzeniowych u chłopców w wieku 10,5 i 12 lat. Klinicznie choroba zamanifestowała się bólami głowy i kręgosłupa w okresie kilku tygodni i kilku miesięcy przed hospitalizacją. U jednego dziecka wykonanie zabiegu operacyjnego było niemożliwe ze względu na rozległość procesu nowotworowego, poddano je chemioterapii. U drugiego chłopca przeprowadzono częściową resekcję guza i zastosowano intensywną chemioterapię. Obydwaj chłopcy zmarli w wyniku progresji choroby, odpowiednio - w 2 i 15 miesięcy od wystąpienia pierwszych objawów neurologicznych. Badanie sekcyjne ujawniło w obydwu przypadkach utkanie glejaków złośliwych z rozległymi naciekami opony miękkiej oraz rozsiew nowotworu drogą płynu mózgowo-rdzeniowego w obrębie układu nerwowego. Zespół bólowy kręgosłupa jest rzadkim zespołem neurologicznym w wieku dziecięcym, wymagającym wnikliwej diagnostyki, ze szczególnym wskazaniem do wykonania badań obrazowych. Pierwszym objawem procesu rozrostowego w kanale kręgowym mogą być również bóle głowy.
