The injection of paraffin for cosmetic purpose is an illegal method as it evokes late complications such as the development of grauuloma, migration of foreign body, inflammation, ulceration, embolic phenomenon, etc. However, paraffin has been used by some unauthorized people for the augmentation of the soft tissue, i.e. face, breasts, as they can easily reansform the body contour in a short time and paraffin is not expensive to do so. Paraffinoma has been reported frequently as a delayed or late complication of foreign body reaction in the field of plastic surgery. And various mehtods of its surgical treatment also has been a topic of plastic surgeon, as postoperative outcome is not satisfactory. As the nose is located at the center of face, the patients who are suffering from paraffinoma in nose could not conceal their deformed appearance by cosmetics. Therefore the only method of improvement is surgical removal of paraffinoma. Paraffinoma of nose has been removed by transcolumellar, infracartilaginous, intercartilaginous incision. However, complete removal of the foreign material does not seem to be possible, may leave complications such as hematoma and overlying skin necrosis, and the remaining foreign material does not permit symmetric appearance. We experienced excision of paraffinoma by direct incision on nasal dorsum. 3 patients with paraffinoma of nose were successfully treated without any complications by vertical elliptical excision on the dorsum of the nose, and scars on nasal dorsum were acceptable with satisfaction by patients. Therefore, the authors concluded that excision of paraffinoma by direct incision on nasal dorsum is a good method for symmetric resection of foreign material, low risk of complication.

Fibrous pseudotumor of the testicular tunics is a rare benign fibrous proliferative disorder, but it is the second most common mass-forining lesion of the testicular tunics. While these lesions are not strict neoplasms, they do form nodules and are often mistaken for neoplasms. Herein, we report 2 cases of fibrous pseudotumor with characteristic histologic findings. Both cases had been incidentally found as slow growing scrotal masses and underwent excision. There were several nodules along the testicular tunics which had bulging whitish-gray cut surface with focal myxoid change and a whorling appearance. These two cases showed the histologic spectrum seen in fibrous pseudotumor from a haphazard arrangement of fibroblastic type cells with intervening collagen and focal lymphocytic infiltrates in case 1, to a densely collagenized lesion in case 2.

Malignant tumor is found in 1-2% of ovarian benign cystic teratomas. Among these malignant neoplasms, squamous cell carcinoma is by far the most common malignancy, whereas the incidence of struma ovarii is less than 5% in mature teratoma. As far as concerned the struma ovarii, a very small percentage is associated with carcinoid, mucinous or serous cystadenoma, or Brenner tumor. However, any reports of struma ovarii associated with squamous cell carcinoma in the same ovary could not be found in English literature. Recently we have experienced a case of squamous cell carcinoma and struma ovarii arising in an ovarian benign cystic teratoma in 72 year old female patient.

Iatrogenically developed immunosuppression-associated Kaposis sarcoma is the result of immunosuppressive therapy after an organ transplantation, particularly after a renal transplantation. Since the advent of powerful immunosuppressive agents such as cyclosporine, recently the incidence of Kaposis sarcoma has been increased. In addition to immunosuppression, other factors, such as genetic predisposition, environmental and geographic factors, and oncogenic viruses, may play a role in the pathogenesis of this tumor. Ilerein we report a case of Keposis sarcoma with multiple organ involvement of the skin, lung, small intestine and mesenteric lymph node in a renal allograft recipient who received cyclosporine and prednisolone. Reduction of the dosage of immunosuppressant for 1 month resulted in improvement of the cutaneous lesions.

Forty-four ovairan tumors were immunohistochemically studied for the presence of broad-spectrum keratin, vimentin, desin, carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), and alpha 1-antitrypsin (AAT) in formalin-fixed, paraffin-embedded tissues. 1) Among the common epithelial tumors, all the serous carcinomas (4) expressed keratin and AAT, and one additionally CEA. Six mucinous carcinomas exhibited keratin-positivity in two. One endometrioid carcinoma coexpressed keratin and vimentin as well as AAT, but one clear cell carcinoma expressed only keratin. Keratin-and CEA-positivity in epithelial cell nests and vimentin-positivity in stromal cells were observed in two Brenner tumors. Two undifferentiated carcinomas showed keratin-positivity in one and focal CEA positivity in the other. 2) In sex cord-stromal tumors, four out of six granulsa cell tumors, all four thecomas and three fibromas expressed vimentin, and two granulosa cell tumors and two thecomas showed AAT-positivity. The others were negative. 3) Among germ cell tumors, four dysgerminomas showed focal vimentin-positive cells in two and diffuse staining for AAT. Seven endodermal sinus tumors expressed AAT in all. Additionally, AFP were positive in two and CEA in three out of them. One embryonal carcinoma expressed CEA, AAT and AFP. 4) In four metastatic carcinomas, three exhibited keratin-and CEA-positivity, whereas one exhibited keartin-and vimentin-positivity. All showed AAT-positivity. 5) There was no positive case for desmin among ovarian tumors.

Localized enterocolic lymphocytic phlebitis is characterized by selective phlebitis involving the small to medium-sized veins and venules, infiltration exclusively by lymphocytes, and no other systemic vasculitis or inflammatory bowel disease. This vasculitis can be a rare cause of intestinal ischemia. We experienced a case of enterocolic lymphocytic phlebitis in a 72-year-old woman, who presented with abdominal pain and distension. The resected colon and terminal ileum showed striking lymphocytic phlebitis affecting the veins and venules of the bowel and mesentery which resulted in ischemic injury of the bowel. This vasculopathy was the only demonstrable cause of ischemia. Arteritis and arteriolitis was not found. There is no clinical or laboratory evidence or a history of extraintestinal vasculitis. The etiology of this clinicopathological entity has not been elucidated. Herein, we report the clinicopathological findings in this patient who presented with ischemic intestinal necrosis caused by localized intestinal lymphocytic phlebitis associated with thrombosis.
