Primary malignant melanoma of the urethra in women: About a case

Primary malignant melanoma of the urethra in women is a rare tumor with a poor prognosis. We report the case of a 48-year-old patient who consulted for a mass in the urethral meatus associated with symptoms of the lower urinary tract. The result of the biopsy of the mass revealed a malignant melanoma confirmed by immunohistochemistry. The extension workup was negative. She had a total cystectomy with lymph node dissection done. The one-year follow-up was without particularity.

Female perineal diseases: spectrum of imaging findings

The female perineum, which is divided into the anterior urogenital triangle and the posterior anal triangle, is a surface structure often overlooked. Female perineal diseases may present with nonspecific clinical signs due to its close anatomical relationship between the different compartments. Diagnosis of the origin of a perineal disorder may also be a difficult problem encountered in pelvi-perineal imaging. Therefore, a precise knowledge of the female perineal anatomy and the associated disease processes is essential to radiologists, pathologists, and surgeons alike who are involved in the evaluation of the patient who presents with a perineal mass. Cross-sectional imaging plays a crucial role for proper management. Due to the robust contrast resolution of MR, MR imaging is the modality of choice for evaluation of the extent of a complex perineal lesion, its relationship to the adjacent structures. It has a greater sensitivity and specificity for the diagnosis than the other non-invasive imaging techniques and is helpful in guidance for surgical planning. The purpose of this article is to highlight the spectrum of imaging findings of female perineal diseases.
