Rare tumors Dotaz Zobrazit nápovědu
Autori referujú o 11 (3,47 %) pacientoch vo veku 8 - 79 rokov (priemer 63,5 roka) so zvláštnym alebo zriedkavým typom primárneho tumoru prostaty, ktorých liečili v rokoch 1987 - 1996. Zriedkavé karcinómy sa u 9 pacientov vyskytli v zmiešanej forme s obyčajným adenokarcinómom prostaty. U 4 pacientov išlo o karcinóm z veľkých (primárnych) duktov prostaty, 5 pacienti mali urotelový karcinóm (1 v čistej forme), 1 pacient mal malobunkový karcinóm a 1 pacient mal čistý rhabdomyosarkóm prostaty. 4 pacienti s incidentálnym adenokarcinómom z primárnych duktov prostaty prežívajú pri hormonálnej liečbe 3-73 mesiacov (priemer 49,8 mesiaca). Ostatni pacienti s pokročilým ochorením v čase stanovenia diagnózy napriek kombinovanej hormonálnej liečbe zomreli za obdobie 1 - 43 mesiacov (priemer 14,7 mesiaca). Hormonálna liečba u pacientov so zvláštnym typom karcinómu nebola úspešná. Metastázy do mozgu u dvoch pacientov s urotelovým karcinómom boli liečené operačne a rádioterapiou s parciálnou remisiou. V diskusii sa rozoberajú laboratórne, klinické a patomorfologické nálezy s možnými závermi pre liečbu.
The authors report 11 (3,47%) patients in the 8-to-79 age-bracket (average age 63,5) treated for an unusual or rare type of phmary prostate tumor during the years 1987 -1996. In 9 patients the rare carcinomas appeared in a mixed form with a regular adenocarcinoma of the prostate. There was a carcinoma arising from large (primary) prostate ducts diagnosed in 4 patients, urotelial carcinoma in 5 patients (1 of them in a pure form), a small-cell carcinoma in 1 patient and a pure rhabdomyosarcoma of the prostate in another 1 patient. 4 patients suffering an incidental adenocarcinoma coming out of the primary ducts have been surviving on hormonal therapy for 3 up to 73 months (49,8 months in average). The rest of the patients with advanced disease at the time of diagnosis died within 1 - 43 months in spite of combined hormonal therapy. The hormonal therapy was not successful in treating patients with rare types of prostate cancer. Surgery and radiotherapy were employed to treat brain metastases in two patients, achieving partial remission. In the discussion the authors analyse the laboratory, clinical and pathomorphological findings and look for possible deductions for the treatment.

Vzácná nádorová onemocnění se podle definice vyskytují u méně než 6 pacientů / 100 000 obyvatel za rok, přesto představují až 24 % ze všech diagnostikovaných malignit. Z patologického hlediska se jedná o široké spektrum morfologicky, fenotypově či molekulárně geneticky definovaných lézí. Jejich diagnostika by měla být komplexní a obvykle vyžaduje kvalitní erudici patologa a dostupnost potřebných vyšetřovacích metod včetně možnosti prediktivního testování. Tento text si klade za cíl přiblížit přístup k histopatologickému hodnocení vzácných nádorů i zdůraznit úskalí jejich diagnostiky.
Rare tumors occur by definition in less than 6 patients / 100 000 population per year. Despite being uncommon, they account for more than 24 % of all diagnosed malignant tumors. As a collective, rare tumors represent a broad spectrum of diagnostic entities defined by morphology, phenotype and molecular characteristics. Diagnostics of rare tumors should be comprehensive including pathologist specialization and availability of special methods for diagnostic as well as predictive purposes. This article aims to summarize the approach to histopathological assessment of rare tumors with emphasis on the diagnostic difficulties.

Autoři uvádí kazuistiky raritního benigního plicního tumoru z jasných buněk a poukazují na to, že peroperační histologické vyšetření ze zmrazovacích řezů může být zavádějící a definitivní histologická verifikace procesu je možná až na základě imunohistochemických vyšetření.
The authors present the case reports of rare benign clear cells tumors of the lung (CCLT) and drawn attention, that examination from frozen sections can be misleading and definitive histological verification can be done on basis of immunohistochemical analysis and can be different from frozen sections examination.

"Diagnostic Pathology: Soft Tissue Tumors, Second Edition strives to reflect the incredible amount of new information that has been uncovered in the field of soft tissue pathology over the last half decade, including changes in terminology and classification (per the latest 2013 World Health Organization Consensus Classification). The new edition includes new chapters and sections that detail both recently described true soft tissue entities/variants as well as mesenchymal tumors that occur outside of standard somatic soft tissue locations (e.g., viscera, gastrointestinal tract), and even those nonmesenchymal tumors and proliferations that often find themselves in the differential considerations of true soft tissue tumors. Additionally, chapters that discuss immunohistochemistry and molecular genetics as they pertain to soft tissue pathology have been remodeled to reflect the stunning proliferation of new antibodies and molecular signatures that seems to expand exponentially month by month. Perhaps most notably, the vast majority of histologic images herein are completely new and unique to the second edition. In addition, the photogalleries in a large number of existing chapters have been expanded to include both salient microscopic features as well as less common and even rare variant morphologies in an effort to more thoroughly photodocument the rich morphologic spectrum of soft tissue pathology."--Provided by publisher.

CONTEXT: Upper tract urothelial carcinoma (UTUC) represents the third most frequent malignancy in Lynch syndrome (LS). OBJECTIVE: To systematically review the available literature focused on incidence, diagnosis, clinicopathological features, oncological outcomes, and screening protocols for UTUC among LS patients. EVIDENCE ACQUISITION: Medline, Scopus, Google Scholar, and Cochrane Database of Systematic Reviews were searched up to May 2021. Risk of bias was determined using the modified Cochrane tool. A narrative synthesis was undertaken. EVIDENCE SYNTHESIS: Overall, 43 studies between 1996 and 2020 were included. LS patients exhibited a 14-fold increased risk of UTUC compared with the general population, which further increased to 75-fold among hMSH2 mutation carriers. Patients younger than 65 yr and patients with personal or family history of LS-related cancers should be referred to molecular testing on tumour specimen and subsequent genetic testing to confirm LS. Newly diagnosed LS patients may benefit from a multidisciplinary management team including gastroenterologist and gynaecologist specialists, while genetic counselling should be recommended to first-degree relatives (FDRs). Compared with sporadic UTUC individuals, LS patients were significantly younger (p = 0.005) and exhibited a prevalent ureteral location (p = 0.01). Radical nephroureterectomy was performed in 75% of patients (5-yr cancer-specific survival: 91%). No consensus on screening protocols for UTUC was achieved: starting age varied between 25-35 and 50 yr, while urinary cytology showed sensitivity of 29% and was not recommended for screening. CONCLUSIONS: Urologists should recognise patients at high risk for LS and address them to a comprehensive diagnostic pathway, including molecular and genetic testing. Newly diagnosed LS patients should be referred to a multidisciplinary team, while genetic counselling should be recommended to FDRs. PATIENT SUMMARY: In this systematic review, we analysed the existing literature focused on upper tract urothelial carcinoma (UTUC) among patients with Lynch syndrome (LS). Our purpose is to provide a comprehensive overview of LS-related UTUC to reduce misdiagnosis and improve patient prognosis.
