Carcinomas of the gallbladder are rare malignancies. They are mostly represented by adenocarcinoma. Pure squamous cell carcinoma is a rare histologic subtype characterized by a rapid growth, with local extension and a poor prognosis. We present a recent case of a 63-years-old man admitted with the complaints of pain in right hypochondrium. Computed tomography revealed a tumour in the gallbladder fossa region with infiltration of the liver. Cholecystectomy was achieved. Pathologic examination of the surgical specimen revealed a well differentiated squamous cell carcinoma. [ABSTRACT FROM AUTHOR]

Background. Primary squamous cell carcinoma of the endometrium is exceedingly rare. It has been described in association with pyometra but its etiology is still unclear.: CaseThe authors report the case of a 75-year-old woman who presented with pelvic pain and pyometra. No gross tumor was identified in the uterus; however, extensive epidermalization of the endometrial mucosa was noted. Microscopic findings were consistent with a primary in situ squamous carcinoma of the endometrium associated with extensive squamous metaplasia and areas of dysplasia. HPV antigen and DNA detection were negative in both the endometrial lesions and the cervix.: ConclusionsThese results support the sequence of change with squamous metaplasia, progressing through dysplasia to carcinoma as a possible pathogenetic process. HPV’s role, however, remains uncertain. [Copyright &y& Elsevier]
