We present a case of malignant mesothelioma (MM) of the tunica vaginalis testis. A 64-year-old man was referred for an operation on a right hydrocele that later proved to be a tumor during surgery. The tumor was malignant with a biphasic pattern of epithelial and sarcomatous components. The latter component was predominant. Cuboidal or columnar cells formed irregular tubular structures in the epithelial component. In contrast, spindle-shaped or polygonal cells formed intricate structures with stromal connective tissues in the sarcomatous component. Immunohistochemical staining revealed that the tumor was mesothelial in origin and positive for cytokeratin, vimentin, HBME-1 antigen and calretinin. In general, MM occur in the pleura or peritoneum; those originating in the tunica vaginalis testis are very rare and represent less than 5% of all MM. In addition, MM in the tissues usually consist primarily of an epithelial component. According to previous reports tumors with a predominant sarcomatous component are extremely rare. In general, a sarcomatous component predicts poor prognosis and our case does, in fact, deteriorate over time. Our case suggests that despite its low incidence, MM must be considered when a case is diagnosed as hydrocele testicle.

“…Über Rezidivität und maligne Transformation adrenaler Adenomatoidtumoren ist aufgrund der geringen Fallzahl nichts bekannt. Maligne Entartung genitaler Adenomatoidtumoren ist nur in Einzelfällen beschrieben [32]; 30 Monate nach Resektion ist auch unser Patient rezidivfrei.…”

Adenomatoid tumors are uncommon, benign tumors of the genital tract which have also been reported to occur extragenitally. Case reports on adenomatoid tumors of the adrenal gland exist. Most of these are incidentally discovered at autopsy or after the resection of incidentalomas. We report on the case of a young man with epigastic pain and with the finding of a 4 cm heterogeneous right adrenal mass on abdominal CT scan. After endocrine activity had been ruled out, an inactive, benign adrenal tumor was suspected and laparoscopic right adrenalectomy performed. The specimen was found to be an adenomatoid tumor. We discuss the differential diagnosis and the possible embryological origin of these tumors. The feature of 'local invasive ability' does not imply malignancy. All cases discovered surgically and at autopsy have been benign. Local resection seems to be the appropriate therapy.

“…3). The tumors have been given various names such as papillary mesothelioma [4], papillary carcinoma, and malignant adenomatoid tumor [5], The etiology is still unknown, also there were some reports that asso ciate the mésothélium tumors with exposure to asbestos [6], prior scrotal procedures [7] or chronic irritation as a predisposing factor [8],…”
