“…However, the areas of atypical nuclear features were focal. Mesothelioma often exhibits diffuse nuclear atypia, with increased mitoses, and apparent invasion into underlying tissue 3,10. The exact etiology of atypical nuclear changes in our case is unclear; these nuclear changes can be attributed to hormonal effects.…”

Adenomatoid tumor is a benign neoplasm of mesothelial origin. Adenomatoid tumor in female genital tract shows typical morphologic features with bland nuclei. Deciduoid morphology has not been reported in adenomatoid tumor. Tumors with deciduoid cells and atypical nuclear features may pose a diagnostic challenge and raise the suspicion of malignancy. We present a case of fallopian tube adenomatoid tumor with deciduoid morphology and atypical nuclear features in a 39-year-old woman with prolonged progestin therapy. We hypothesize that the unusual morphological changes in adenomatoid tumor, like deciduoid morphology and nuclear atypia, may be secondary to hormone effects.

“…The cells are found discretely or in loose aggregates. Unlike malignant mesothelioma, adenomatoid tumor do not show nuclear atypia or mitotic figures . Differentiation of mesothelioma from metastatic adenocarcinoma and rare cases of rete testis adenocarcinoma is difficult and sometimes impossible in cytomorphology .…”

Malignant mesothelioma of tunica vaginalis testis is a rare aggressive neoplasm with ∼200 cases reported so far. A correct preoperative diagnosis of this rare tumor is difficult. Fine-needle aspiration cytology (FNAC) is a rapid and inexpensive diagnostic tool that may prove helpful in such cases. Very few cases have been diagnosed on cytology so far, and the descriptions of the cytological features have rarely been described in the literature. In this report we present the cytological features of malignant mesothelioma of tunica vaginalis testis which was diagnosed by FNAC and subsequently confirmed by histopatholoy and immunohistochemical (IHC) studies.

“…However, in our case, multiparametric ultrasound mimicked testicular cancer, confirming a vascularized and hard lesion of 0.9 cm. Nevertheless, fine needle aspiration cytology (FNAC) seems to be an attractive diagnostic method in case when adenomatoid tumor is supposed [ 15 , 16 ]. Cytological features include dilated tubular structures lined by epithelial cells with round or oval nuclei, with clear and vacuolated cytoplasm in Papanicolaou staining, staining pink with Giemsa stain [ 15 , 16 ].…”

Nevertheless, we did not perform FNAC for further diagnostic evaluation as RTE and CEUS confirmed all sonographic criteria of a malignant testicular cancer.…”

Adenomatoid tumor of the testis mimicking malignant testicular cancer on multiparametric ultrasound

BackgroundAdenomatoid tumor is one of the most common histological subtypes of paratesticular cancer arising from the epididymis. In very rare cases, these tumors appear as intratesticular lesions originating in the tunica albuginea, representing a diagnostic challenge.Case presentationWe present a case of a 51-year-old man with a small (0.9 cm) hyperechoic lesion of the left testicle mimicking testicular cancer on multiparametric ultrasound. The lesion was localized in the peripheral zone, confirming vascularization and increased stiffness on contrast-enhanced ultrasound and real-time elastography. Preoperative tumor markers and hormone levels were within normal ranges. Staging computed tomography was negative. Organ-sparing surgery with tumor enucleation and frozen section analysis was performed, confirming testicular adenomatoid tumor.ConclusionCurrently, no typical ultrasound features can definitively distinguish intratesticular adenomatoid tumors from malignant testicular masses. Thus, a surgical approach is almost always considered in such a case for both diagnostic and therapeutic purposes.
