Multiple Primary Tumors Originating From the Prostate and Colorectum A Clinical-Pathological and Therapeutic Challenge.

Considering that the incidence of colorectal (CRC) and prostatic cancer (PC) increases with age, metachronous and synchronous tumors can often affect the same patient. Despite the importance of this subject for the diagnosis and management of oncologic patients, in medical literature the data are scarce. The aim of the study was to evaluate the incidence and the characteristics of double/multiple primary malignant tumors (D/MPMTs) with colorectal and prostatic origin, in patients admitted to a reference hospital in West Romania.

The new WHO classification of gastrointestinal neuroendocrine tumors and immunohistochemical expression of somatostatin receptor 2 and 5.

The 2019 World Health Organization (WHO) classification of gastrointestinal tumors defines well-differentiated grade 3 neuroendocrine tumors, the mixed neuroendocrine-non-neuroendocrine tumors (MiNENs) and classifies goblet cell carcinoid as goblet cell adenocarcinoma. The expression of somatostatin receptors (SSTRs) is the foundation for somatostatin analogue therapy. At present, there are only a few studies that have analyzed the immunohistochemical reactivity of SSTRs in gastrointestinal neuroendocrine neoplasms (NENs).

Sclerosing Extramedullary Hematopoietic Tumor (SEHT) Mimicking a Malignant Bile Duct Tumor-Case Report and Literature Review.

: Sclerosing Extramedullary Hematopoietic Tumor (SEHT) is a very rare lesion associated with chronic myeloproliferative disorders (CMPD). SEHT can mimic morphologically, both macroscopically and microscopically, a wide variety of tumors/lesions. : We present the case of a female patient diagnosed with gallstones for which surgery was decided.

Carcinomatous-like mastitis due to axillary lymphadenopathy in a case of nasopharyngeal carcinoma: A case report.

Nasopharyngeal carcinoma (NPC) is a rare form of malignancy, accounting for 2% of all cancers of the head and neck in Europe. Axillary lymph node metastases are very rare in these cases. This is a case report of a 40-year-old premenopausal woman diagnosed in May 2015 with T1N2M0 stage III NPC, treated with induction chemotherapy, followed by chemo-radiotherapy.

Prostate carcinomas mimicking a digestive malignancy.

Aim: To report our experience with specific cases of prostate cancer (PC) in which patients presented digestive symptoms, cases that represent a challenge and a source of error regarding the clinical and morphological diagnosis.

Methods: The most important clinical and pathological data were collected from three patients with PC which presented symptoms and/or investigations that initially suggested a digestive malignant tumor.

Results: We identified three patients with PC where the prostate tumor was not suspected based on the clinical-imagistic data, the correct diagnosis being the prerogative of the morphological investigation: in the first case, PC was detected during the microscopic examination of the lymph nodes (LN) in the intestinal resection specimen performed for suspected rectal cancer (RC), in the second case, in which the PC was synchronous with a RC, the dominant symptomatology was gastrointestinal, and in the third case, initially, the patient presented a widely disseminated PC, with pleural and bone metastases, as well as LN metastases, and apparent peritoneal involvement.

Unexpected diagnosis for a gastric polyp: Granular cell tumor: Case report and review of the literature.

A granular cell tumor (GCT) is a rare neoplasia that originates from Schwann cells. It usually appears in the skin or soft tissues, but it may occur anywhere in the body. The gastrointestinal tract is an unusual developmental site for a GCT, the esophagus being the most common site of origin for this tumor.

Paving the way to tumor budding assessment using digital pathology: a pilot study in Timişoara City (Romania).

Background And Aim: The outcome for some colorectal cancer patients correlates poorly with classical prognostic factors, like tumor stage. Tumor budding (TB) is a promising and intensely studied new prognostic factor. We aimed to evaluate the reliability of bud counting on Hematoxylin-Eosin (HE)-stained and immunohistochemically (IHC)-stained scanned slides.

Surgical treatment in a case of giant macrodystrophia lipomatosa of the forefoot.

Macrodystrophia lipomatosa is a rare, congenital, non-hereditary disease, characterized by local gigantism of the fingers or toes. We report the case of a 37-month-old boy, with no prior past medical history, who presented with a gigantic dystrophy of the left forefoot. The location of the deformity was involving the plantar and dorsal aspect of the foot, and digits 1 to 4.

In vivo confocal microscopy quantification of reactive oxygen species: a working model in rat kidney.

Oxidative stress is a culprit responsible for the development of acute and chronic kidney diseases. We aimed to establish a working model for the dynamic in vivo assessment of reactive oxygen species (ROS) production in rat kidney. A randomized controlled study was performed in 36 adult male Wistar rats subjected to unilateral urinary obstruction (UUO) via ureteral ligation and compared to SHAM controls.
