Cyst of the canal of Nuck is a rare cause of inguinal swelling in woman. We report a case of a cyst of the canal of Nuck in which sonography showed a tubular cystic structure with internal septae localized within the inguinal canal. Magnetic resonance examination demonstrated that the mass was hypointense on T1-weighted and hyperintense on T2-weighted series and that there were fine hypointense septae inside the mass on the T2-weighted sequence. Diagnosis of cyst of the canal of Nuck was confirmed by surgery and subsequent histopathologic evaluation.Sommario La cisti del canale di Nuck è una rara causa di tumefazione inguinale nelle donne. Riportiamo un caso di cisti del canale di Nuck in cui l'ecografia aveva evidenziato una struttura tubulare cistica caratterizzata da setti interni, localizzata nel contesto del canale inguinale. L'esame di RM aveva confermato la natura cistica della lesione, che appariva pertanto ipointensa in T1 e iperintensa con fini sepimentazioni ipointense nelle sequenze T2 pesate. La diagnosi di cisti del canale di Nuck è stata successivamente confermata all'intervento chirurgico e dall'esame isto-patologico. ª

Our findings indicate that human thyroid development can occur despite loss of TTF-2 function and suggest that TTF-2 gene defects should also be considered in cases of syndromic CH without total athyreosis.

Extramedullary plasmacytomas (EMPs) are localized plasma cell neoplasms that occur within the soft tissues; by definition they cannot occur within bone. They account for 1-2% of all plasma cell growths and have a great predilection for the upper respiratory tract, without specific manifestations. Males are more frequently affected during the fifth and sixth decades of life. At initial presentation, multiple myeloma should be excluded. We report herein the case of a 63-year-old man with an EMP arising in the right maxillary sinus who was referred for surgical excision and postoperative radiotherapy and briefly review the clinical implications and management of this pathology.

We present a patient with symptoms of abdominal pain and frequent urination due to a huge mass in the retrovesical region. All imaging modalities revealed a cystic mass containing small daughter cysts located between the urinary bladder and rectum. Its characteristics led us to suspect the presence of a hydatid cyst, and an indirect hemagglutination test for Echinococcus granulosus was found positive. No other involvement of hydatid cystic disease was detected. The primary site for the hydatid disease was therefore regarded as the pelvis, on which only a few cases have been reported previously. The patient started albendazole therapy, but refused operation. Hydatid cyst should always be considered in the differential diagnosis of abdominopelvic masses in endemic regions of the world.
