RESUMO
Small cell neuroendocrine carcinoma of the uterine cervix (SCNCC) is a rare form of cervical carcinoma. Precise and early diagnosis of SCNCC is crucial because of its poor prognosis and distinct therapeutic approach compared with other common squamous cervical cancers. This report presents a case of SCNCC in a 50-year-old woman with vaginal bleeding. On computed tomography and magnetic resonance imaging (MRI), the tumor presents as a bulky, expansile, solid mass with a homogenous texture, low apparent diffusion coefficient (ADC) value, and extensive nodal and distant metastases. Mimicking lymphoma, the tumor did not exhibit cervical epithelial distortion. The diagnosis of SCNCC was confirmed by punch biopsy, and the patient was treated with systemic chemotherapy. MRI features that suggest SCNCC are lesion homogeneity, low ADC values, and frequent nodal metastases, which are commonly observed in lymphomas. Therefore, despite its rarity, SCNCC should be considered in the differential diagnosis when a cervical mass presents with these findings.
RESUMO
Leiomyosarcoma (LMS) within the scrotum is a rare malignant genitourinary tumor in adults. Due to its rarity, a consensus on a clear approach to diagnosis and treatment guidelines has not yet been reached. We present a case of a paratesticular LMS in a 64-yearold man with a painless swelling of the right scrotum. Scrotal ultrasound and pelvic MRI were performed and revealed an extratesticular mass with a heterogeneous appearance.The patient underwent a right radical orchiectomy, and the mass was confirmed to be LMS, originating from the right spermatic cord. Preoperative diagnosis of LMS is challenging since it has overlapping clinical and imaging features with other sarcomas. MRI is a valuable imaging modality for the definitive characterization of the tumor. To provide timely and appropriate treatment, the correlation of the patient’s clinical information and imaging findings is necessary.
