Basal cell carcinoma (BCC) is currently the most common cutaneous cancer found in humans. Although it generally shows a relatively benign course (BCC1), some cases of BCCs show "aggressive" behavior, rapidly infiltrating deeper structures, or metastasizing (BCC2). Until now, the traditional histological diagnostic criteria have failed to discriminate(More)
Among the primary mesenchymal tumors of the hypopharynx and larynx, lipomas are rare. Macroscopically, they often resemble a retention cyst or laryngeal nodule. Spindle cell lipomas (SCLs) are an uncommon variant of lipoma. SCLs are extremely rare in the larynx; as far as we know, only 4 cases have been previously described in the literature. We present a(More)
Basal cell carcinoma (BCC) is the most frequent cutaneous neoplasm, with a generally favorable clinical behavior. Sometimes, indeed, it recurs after therapy and/or metastasizes. As point mutations in the coding sequence of the p53 tumor suppressor gene have been implicated in the progression of many human tumors, we studied the expression of p53 protein on(More)
Thirty patients with distal ulcerative colitis in remission (17 proctitis, 13 proctosigmoiditis) were randomly given either 5-aminosalicylic acid (5-ASA) or placebo suppositories, 400 mg bid. During the 1-yr follow-up, patients were assessed clinically every month, and flexible sigmoidoscopy with a rectal pinch biopsy specimen and laboratory data were(More)
The findings of fine needle aspiration biopsy cytology, histology, immunohistochemistry and electron microscopy in an extraskeletal myxoid chondrosarcoma of the soft tissue of the thigh detected in a 65-year-old man are described. In addition to the more usual cytologic findings of chondroblasts and pleomorphic mesenchymal cells, this tumor displayed(More)
The role played by the tunica albuginea in the erection mechanism seems to be very significant in promoting the constriction of sub-albugineal venous reticulum and trans-albugineal effluent veins, as well as providing an inextensible protective structure to the arteriolae and to the intracavernous nerves. The passive function exerted by the tunica albuginea(More)
Peyronie's disease, the etiology of which remains unknown, is characterized by a focal or multifocal disorder of penile tunica albuginea. An excessive collagen deposition gives rise to the formation of the plaque, which is fibrotic first and then becomes calcific. Typical symptoms of the disease are painful erection, pathological bending of the erect penis(More)
A case of multicystic mesothelioma of the liver with secondary involvement of the pelvic peritoneum and the inguinal region is presented. The case is of interest because of its unusual location and peculiar biological behavior.
A rare case of verruciform xanthoma of the vulva is reported. Diagnosis was made possible by histopathological examination and immunohistochemical staining. Verruciform xanthomas generally occur in the oral cavity. To the best of our knowledge, this is the third reported case of the tumour located on the genital mucosa. Immunohistochemical study supported(More)
