With 2mm-thick CT scanning during the rapid infusion of contrast material(TICT), cerebral aneurysms arising from the circle of Willis and adjacent vessels can be directly visualized. Twenty-five patients who had cerebral aneurysm confirmed by surgery were examined with TIGT and digital subtraction angiography. The authors examined TIGT prospectively to assess the detection rate of the cerebal aneurysms and to evaluate the clinical usefulness of TIGT. The detection rates of aneurysms by TIGT and digital subtraction angiography were 68% and 84%, respectively. TIGT is a rapid, safe and reliable method in the evaluation of patients with suspected cerebral aneurysm, permitting direct visualization of the aneurysm.

We describe cytologic findings of two cases of pilomatrixoma which had been cytologically misdiagnosed as suspicious malignant and malignant lesions in 35 year-old and 22 year-old females who presented a palpable neck mass. The cytologic smears showed many basaloid cells with a high nuclear-cytoplasmic ratio, nuclear hyperchromatism and prominent nucleoli, keratinized squamous cells with pyknotic nuclei, foreign body giant cells, and chronic inflammatory cells in necrotic background. Retrospective view of this aspiration smear revealed that these findings were characteristic features of pilomatrixoma, and the evenly distributed chromatin pattern as well as the lack of nuclear pleomorphism were considered to be the differential points from malignant neoplasm. Pilomatrixoma is a benign neoplasm which should be included in differential diagnosis if the fine needle aspiration cytologic smear of a neck mass or subcutaneous mass of any site showed these features.

To evaluate the appearance rate of typhoid granuloma, a clinical and histological study was made on bone marrow smears or biopsies of 60 patients with proven typhoid fever. The results were as follws: 1) Sixty cases consisted of 34 cases of bacteriologically proved group, 10 cases of serologically proved group, and 16 cases of clinically suspected group. The positive culture rate from bone marrow fluid was the highest (70.6%) among specimens although it was obtained 1.6 days in average after the administration of antibiotics. 2) Fourth-eight cases by bone marrow smear revealed the M:E ratio of 3.93:1 in average, mild myeloid hyperplasia and 50.5% of appearance rate of typhoid cells. 3) Fourth-nine cases of bone marrow biopsy revealed 8 cases of typhoid granuloma, all of which belonged to the bacteriologically proved group. All these have no pathognomonic morphologic features. 4) Fourty cases of bone marrow examination of patients with FUO except typhoid fever revealed no typhoid cells in smear and 3 cases of granulomatous lesion from two patients with miliary tuberculosis and one patient with Hodgkin's lymphoma.

The spotted grouped pigmented nevi is one of special forms of non-giant congenital melanocytic nevi. Histologically the nevus cells tend to proliferate around the skin appendages. We have experienced a case of spotted ground pigmented nevi in a 11 year old girl who had a pigmented plaque consisting of grouped brown black regularly distributed papules on the left inguinal region since birth. Histology revealed intradermal nevus. The skin appendages, especially the hair follicles and eccrine sweet ducts were enveloped by the neuvs cells. Electron microscopic study revealed that this nevus cells were mostly of type B cells. We would like to consider that the spotted grouped nevi are closely related pathogenically with the skin appendages.

A Histologic finding of the Cutis marmorata telangiectatica congenita( CMTC) is non-specific, but dilated capillaries and increased number of vessels are often observed. Capillary hemangioma, mostly represented by strawberry nevus, may show various clinical manifestations. We report a case of Cutis marmorata telangiectatica congenita, which may be an unusual clinical presentation of capillary hemangioma.

Although cystic teratoma is the most common benign tumor of the ovary, the association of sebaceous gland tumor with cystic teratoma is rare. We have recently experienced a case of sebaceous gland tumor, arising in the cystic teratoma of the ovary in a 78-year-old Korean woman. Histologically, the tumor was characterized by an organoid lobular architectures of the sebaceous glands which are exculsively composed of germinative and mature sebaceous cells. Although it is difficult to come to a valid conclusion due to the presence of atypical mitosis and necrosis, this tumor was regarded as benign from the viewpoint of preserved organoid structures, and absence of capsular invasion or metastasis.
