Primary bone leiomyosarcoma of distal femur: case report and literature review.

We present the case of a 58-year-old patient presented with a spontaneous right supracondylar fracture. The initial bone biopsy, highlighted the defining histopathological (HP) elements for a leiomyosarcoma (LMS), initially considered a metastasis. The complex imaging examinations did not reveal another tumor, so the final diagnosis was primary bone LMS.

SARS-CoV-2 Infection during Pregnancy and Histological Alterations in the Placenta.

(1) Background: Despite the high number of cases of COVID-19 during pregnancy, SARS-CoV-2 congenital infection is rare. The role of the placenta as a barrier preventing the transmission of SARS-CoV-2 from the mother to the fetus is still being studied. This study aimed to evaluate the impact of SARS-CoV-2 infection on placental tissue.

Synchronous bilateral primary ovarian carcinoma - case presentation.

Bilateral synchronous primary ovarian carcinoma, histopathologically identical or different is a rare entity encountered in clinical practice. We present the case of a 38-year-old patient who is admitted with the presence of a massive pelvic abdominal tumor formation of 45÷35÷25 cm occupying the lower pelvic and upper abdominal floor, reaching halfway distance between the umbilicus and sternum and lateral bilaterally in the two abdominal flanks until iliac wing. The mixed transabdominal÷transvaginal ultrasound and computed tomography (CT), establish the diagnosis of bilateral ovarian tumor.

Review of the biotechnologies and tests used for precancerous cervical lesions diagnosis.

This paper draws on the author's extensive experience in the clinical research focused on the implementation of the new biotechnologies able to identify precancerous cervical lesions and is intended to be a systematic approach to new achievements. The goal of this review is to provide updated information concerning the significance of each biotechnology used in clinical medicine to screen women for cervical cancer or to allow a pertinent discrimination between spontaneous remission lesions and progressive lesions. The data is arranged according to the most widely used biotechnologies and the worldwide recommendations of specialized guidelines.

Epithelioid trophoblastic tumor: a case report and literature review.

Epithelioid trophoblastic tumor (ETT) is a very rare case of malignant trophoblastic tumor, which can occur particularly during the fertile age of women with a long history of abortion and delivery. ETT originates from the intermediate trophoblastic cells of chorion laeve. The main features of this tumor include lack of vessels within the tumor, nuclear hyperchromasia and pleomorphism and a large zone of necrosis and hyalinization.
