Multiple sclerosis (MS) may rarely present as a cerebral mass with the clinical features and computed tomography (CT) scan appearance of a cerebral tumor. We report a case of MS with large cranial involvement showing a mass effect. We carried out a complete examination, including contrast enhancement, with neuroimaging studies. The operative procedure associated with medical treatment was performed and we obtained a good result.
BACKGROUND: Focal epithelial hyperplasia (FEH) is an uncommon benign oral condition that occurs mainly in young individuals of certain racial groups. METHODS: A 21-year-old Caucasian man presented with FEH of the oral mucosa. The patient was treated with interferon alpha-2a three times a week for 14 weeks intramuscularly (a total of 162 million units). RESULTS: At 2 months after the end of therapy, the papular lesions showed partial regression. CONCLUSION: This treatment modality should be used in cases with diffuse focal epithelial hyperplasia.

Male breast cancer, consisting only 1% of all breast cancers, is occasionally associated with other primary malignancies, especially in patients with familial breast cancer history. Sporadic male breast cancers with another primary tumor are extremely rare. We report a 67-year-old male with asynchronous bilateral breast cancer and prostate cancer without familial breast cancer history.

The decalcification process removes the mineralized part of the dental hard tissues, making the histologic examination of enamel-associated tissues less than optimal. The cutting-grinding technique allows preparation of histologic slides with well preserved dental hard tissues together with their surrounding soft tissue components. In this paper, the histologic appearances of undecalcified teeth and their associated periodontal tissues prepared using the cutting-grinding technique are described.

Secondary oxalosis of bone is a complication of chronic renal failure. Its frequency and the mechanism of the deposition is unknown. We report the case of chronic renal failure patient on hemodialysis with deposition of oxalate in bone. Possible mechanisms and the significance of the depositions is also discussed.
OBJECTIVE: To determine the fine needle aspiration biopsy (FNAB) findings in hepatic Echinococcus multilocularis. STUDY DESIGN: FNAB and tru-cut liver needle biopsy were applied in 14 hepatic E multilocularis cases. Cytologic smears were stained with May-Grünwald-Giemsa and periodic acid-Schiff (PAS) stain. Tissue sections were stained with hematoxylin-eosin (HE) and PAS stain. RESULTS: In tissue sections, homogeneous, thin, cystic structures of various dimensions strongly stained with PAS. Mucoid material was stained with PAS in the cystic structures. Wide, coagulative necrosis was observed in all cases. In some cases there were foreign body-type giant cells at the periphery of the lesion. In all the cytologic smears there were an intense necrotic ground, PAS-positive hyaline cuticular structures and mucoid globules; in some cases there were foreign body-type giant cells. CONCLUSION: The above cytologic characteristics are basic diagnostic criteria for FNAB of E multilocularis.
Fine needle aspiration cytologic findings in two cases of malignant lymphoepithelial lesion (MLEL) of the parotid glands are presented. Aspirates of both cases showed individual or cohesive clusters of tumor cells intermingling with mature lymphocytes. Cervical lymph node aspirates in both cases were similar to those seen in the parotids. Our findings suggest that neither cytology nor histology of the cervical lymph nodes is conclusive in establishing the primary site of a metastatic lymphoepitheliomalike carcinoma. MLEL of the salivary glands must be included in the differential diagnosis.
