BACKGROUND: Alopecia areata is replete with data from studies using variuos therapeutic approaches, none of which is clearly superior to another. OBJECTIVE: This study was designed to evaluate the therapeutic effect of cryotherapy in alopecia areata. METHODS: Thirty three patents with AA(M:13, F:20) well conduted in this study, precluding 3 patients with the moderate and extensive lesions. Cryotherapy using a cotton swab dipped with liquid nitrogen was applied to the involved areas, repeated with 2 times of freeze thaw cycle of two seconds. In 13 cases of AA multiplex, the lesions were divided into two groups, each of which was undertaken cryotherapy and intralesional injection of triamcinolone(3mg/ml) for evaluation of their respeetive effects. The treatment was done weekly method of 1 to 11 times, Th therapeutic response was determined as the regrowth of terminal hairs on the treated area(s) at 12 Weeks. RESULTS: Of the 33 patients with AA, the overall responders were 22(66.7%). There seemed good response rates of 70.0 % in females, 71.4 % in AA multiplex and 72.2 % in third decade as well as 72.4 % in those with lower than 1 year of duration. The remarkable resionse had 3-4 times in treatment numbers. There were no untoward side effects in patients except mild erythema. In the 13 patients treated with both modalities, cryotherapy had a slightly higher esaonse than triamcinolone therapy (69.2% vs 61.5%, p>0.05 by x-test). CONCLUSION: The effect of cryotherapy therapy in AA patients is not less than the intralesional therapy of triamcinolone. In addition, cryotherapy may be recommendec as the new, safe therapeutic modality.

A case of desmoplastic fibroma of mandible in a 18 years old woman is presented. She had complained progressive swelling of right mandible for 4 years. Radiographically, a multilocular radiolucent of right hemimandibulectomy showed multinodular external surface without cortical destruction. Cut surfaces revealed grayish white, fibrous homogeneous appearance with firm consistency, sparing head portion. The maximum diameter of the tumor was 13 cm. Microscopically, the tumor was composed of interlacing bundles of monomorphic spindle-shaped cells with abundant intercellular collagen. Ultrastructurally, most tumor cells were fibroblastic-like cells with abundant RER and cytoplasmic fibrils, but a few disclosed transition to myofibroblasts. However, no fully developed myofibroblasts were seen.

Malignant mixed mesodermal tumor (MMMT) of the ovary is endometrioid tumor containing epithelial and mesenchymal components. The mesenchymal component may be homologous, in which case the term carcinosarcoma is often used, or heterologous, containing cartilage, striated muscle, osteoid, bone, or fat, or combination of these elements. MMMT usually afflicts the postmenopausal woman and occurs more often in the nulliparous female. The disease is usually advanced (stage III) when diagnosed. Cliniopathologic data were presented for 3 cases of MMMT of the ovary with review of literatures. Clinical history substantiated previous reports in postmenopausal women wit this tumor. Symptoms were the same as for ovarian malignancy in general. All the patients presented wit stage II disease, according to the International Federation fo Gynecology and Obstetrics (FIGO) classification. Two patients died of tumor 4 and 10 months after operation, respectively. One patient had been alive at 2 months after operation. None of 3 cases demonstrate evidence of endometriosis in the remaining ovaries. Microscopically, periodic acid-Schiff (PAS)-positive, diastase-resistant hyaline droplets were found frequently in undifferentiated mesenchymal stroma and epithelial structures. The clinical significance and origin of the hyaline droplets in MMMT should be further explored.

Because neuroblastoma is predominantly a tumor of childhood, patholgists and clinicians tend to exclude it from differential diagnosis when the patient is an adult. The diagnosis of neuroblastoma by light microscopy can be difficult because of similarities between neuroblasts and cells of other round cell neoplasms. The fine structural features of neuroblastoma is distinctive and is valuable in its diagnosis. We present 2 cases of neuroblastoma and a case of ganglioneuroblastoma arising in adults with their ultrastructural findings.
