Uterine Leiomyomas with Specific Histology Features of Two Fumarate Hydratase/Succinate Dehydrogenase-Deficient Tumors: A Double Case Report

Background and Objectives: Mutations in succinate dehydrogenase (SDH) and fumarate hydratase (FH) give rise to various familial cancer syndromes, with these alterations being characteristic of certain types of histomorphologically specific leiomyomas that hold significant predictive value. Materials and Methods: This study presents two cases of uterine leiomyomas exhibiting rare histomorphological and genetic characteristics, which are crucial for prognosis and further treatment. Results: Distinct histopathological features such as marked nuclear atypia, intracellular eosinophilic globules, and abnormal intratumoral vessels raise suspicion for specific leiomyoma subtypes, which carry predictive significance for additional hereditary cancer syndromes. Immunohistochemical analysis confirmed FH/SDH deficiency in both patients, who underwent careful follow-up. Conclusions: This study describes two cases involving unusual leiomyomas, the histopathological characteristics of which may easily go unrecognized. These features hold predictive significance because their specific mutations point to additional hereditary cancer syndromes, highlighting the need for further examinations.

Curious Case of Superfitial Spreading Cervical Squamocellular Carcinoma with Adnexal Involvement

Background and Objectives: Cervical squamous cell carcinoma (SCC) usually showed an infiltrative growth pattern into endocervical stroma. In rare cases, SCC spreads superficially as an intraepithelial lesion to proximal uterine segments, and more rarely, involves invasive and more aggressive behavior on secondary sites. Materials and Methods: In this study, we present the case of an interesting form of cervical SCC growth and we discuss the possible reasons for that presentation. Results: After clinical examination and repeated histomorphological analysis, we found remarkable cervical epithelial dysplasia (a high-grade squamous intraepithelial lesion—H-SIL). A histopathology report after conization and hysterectomy showed squamocellular carcinoma with microinvasive focuses. Interestingly, squamocellular carcinoma was found in the proximal uterine and adnexal structure, as well as intraepithelial and microinvasive lesions. Conclusions: Our study described a rare presentation of primary cervical SCC with unusual adnexal involvement. This pattern of tumor growth should be especially considered for patients who are proposed for sparing surgical procedures. A detailed and multidisciplinary approach for every patient is very important because unpredictable cases are present. However, they are rare.
