Solid and papillary epithelial neoplasm of the pancreas is a rare, low grade malignant tumor of adolescence. The tumor we described was diagnosed by following preoperative percutaneous fine needle aspiration biopsy and confirmed by tissue examination. Characteristic cytologic findings were monotonous cells arranged in papillary fronds, acinus, and cords in necrotic and hemorrhagic backgrounds. Occasional foamy histiocytes and hyaline globules were present. The cytoplasm of the tumor cells were moderate in amount, pale eosinophilic or vacuolated with distinct borders. The nuclei were centrally located and round. There were one or two small nucleoli and finely granular chromatin throughout the nucleus.

This is a case of recurrent malignant fibrous histicytoma, histologic features of which are reminiscent of a clear cell carcinoma of soft tissue or myxoid liposarcoma. The tumor recurred 2 years and 10 months after the initial removal of the primary tumors in the lateral aspect of the left tigh. In view of histogenesis of malignant fibrous histiocytoma, possibility of recurrent tumor with a wide range of histologic features including clear cell type is discussed. Pertinent clinical history with review of the initial tumor is mandatory for a definite assessment of histologic feature of recurrent malignant fibrous histiocytoma.

We studied 24 cases of cutaneous T-cell lymphomas and six cases of benign lymphoproliferative diseases of the skin (2 Jessner's lymphocytic infiltration, 2 pseudolymphoma, 2 lymphomatoid papulosis) for the presence of Epstein-Barr Virus(EBV) RNA, using the in situ hybridization(ISH) method. Among the 24 cases of cutaneous T-cell lymphomas (CTCL), 18 cases including 12 cases of mycosis fungoides(MF) were primary CTCL, and the other 6 cases were secondary CTCL. The ISH study demonstrated a positive reaction for EBER probe in 6 out of the 24 cases(25%) of CTCL, and a negative reaction for BHLF nuclear RNA probe in all the cases studied. Double-labelling immunohistochemistry/ISH studies revealed that the EBV positive cells were CD45RO positive and CD20 negative. EBV genome was not demonstrated in any benign lymphoproliferative diseases of the skin. Among the EBER positive cases, none of the 12 cases of MF demonstrated EBER signals, and 6 out of the 12(50%) cases of CTCL were positive for EBER probe. In conclusion, latent infection of EBV may play a role in the development of non-mycosis fungoides T-cell lymphomas involving the skin.

Sclerosing lymphangitis of the penis is a peculiar disorder characterized by painless, firm, cord-like lesion in the coronary sulcus of the penis. Histologic findings include thickened lymphatic collecting vessels, fibrin thrombi and few inflammatory changes. The etiology is unknown, but the condition is benign and self-limited. We describe herein a 27-year-old man who had a typical painless, tender, firm, cord-like lesion in the coronary sulcus. Histologic findings disclosed a markedly thickened and fibrosed lymphatic vessel with a organizing thrombus. Whatever the cause of thrombi formation, it is prohable that the thrombi formation would be a main pathologic process, followed by the thickening of the vessel wall.

Congenital immature teratoma of the tongue is a exceedingly rare form of epignathus. We report here an autopsy case of a huge immature teratoma protruding from the tongue of a newborn female infant. The mass obstructed the mouth and caused hydramnios. The mother's serum level of alpha-fetoprotein was elevated, and the tumor was identified by a ultrasonogram subsequently done. Discussion on the histogenesis of epignathus was made through a review of literatures.

Gross deciduosis in pregnancy is rare. A case of disseminated deciduosis peritonei studied by light and transmission electron microscopy is reported. The pathogenesis of deciduosis peritonei and relationship with leiomyomatosis peritonealis disseminata are discussed in view of the present findings and those previously reported.

Atypical condyloma is a variant of flat condyloma characterized by the presence of atypical koilocytes having large hyperchromatic, smudged and often bizarre nuclei. Atypical condyloma can be frequently misdiagnosed on cytologic smear and on tissue sections by its marked cellular atypia, as high grade dysplasia, in situ or even invasive squamous cell carcinoma. We described two cases of atypical condyloma of the female genital tract. The cytologic features and histologic changes were reminiscent of those of invasive squamous cell carcinoma and severe degree of dysplasia of the uterine cervix. The differential findings between atypical condyloma and squamous cell carcinoma were discussed in detail.

Eosinophilic fasciitis is a syndrome which is characterized by scleroderma-like skin involvement, eosinophilia and hypergammaglobulinemia without significant systemic changes. The primary pathological alterations are thickening and inflammation of the deep fascia. The majority of the cases that have been reportecd respond to systemic corticosteroids. We describe a 19-year-old male patient with eosinophilic fasciitis. On physical examination, he showed tender, edematous, indurated and tight skin in the back and both lower legs, and the laboratory findings showed eosinophilia and mild hypergammaglobulinemia. He also had Raynaud phenomenon, mild dyspnea, abdominal pain, pulmonary function abnormalities and roentgenographic evidence of pulmonary fibrosis. Result of a biopsy showed sclerosis of dermia and intense infiltrations of eosinophils, lymphocytes and histiocytes and fibroais of panniculus and fascia. Treatment with systemic corticosteroids showed complete resolution of the skin lesions, but after withdrawal new scleroderma-like skin lesions developed in the dorsum of feet.
