A case of multiple hamartomas of the unilateral chest wall in a four month old infant is presented. There have been a few reports on the CT findings of the chest wall hamartoma in infancy. We describe bone changes of the ribs and mineralization of this rare tumor on the CT scan, and the locations of two separate masses.

PURPOSE: To evaluate the utility of FLAIR (Fluid Attenuated Inversion Recovery) MR imaging in cerebral infarction by comparing its results with those of T2-weighted spin-echo imaging. MATERIALS AND METHODS: We retrospectively evaluated fast FLAIR images and conventional spin echo images of 82 patients (47 men and 20 women; median age 60.9 years) with cerebral infarction. MR imaging used a 1.5T MR unit with conventional T2 (TR 3900, TE 90) and fast FLAIR sequence (TR 8000, TE 105, TI 2400). We analysed the size of the main lesion and number of lesions, and discrimination between old and new lesions and between small infarction and perivascular space. RESULTS: When T2-weighted and FLAIR imaging were compared, the latter showed that the main lesion was larger in 38 cases (46%), similar in 38 (46%), and smaller in six (7%). The number of lesions was greater in 23 cases (28%), similar in 52 (63%), and fewer in seven (9%). FLAIR images discriminated between old and new lesions in 31 cases ; perivascular space and small infartion were differentiated in eight cases, and CSF inflowing artifact was observed in 66 (80%). CONCLUSION: In the diagnosis of cerebral infaretion, fast FLAIR provides images that are equal or superior to T2-weighted images. The fast FLAIR sequence may therefore be used as a part of routine MR brain study in the diagnosis of cerebral infarction.

PURPOSE: To evaluate differential points of clustered microcalcification in malignant and benign lesions on histopathology and correlate with mammographic findings. MATERIALS AND METHODS: Authors evaluated differential points of malignant and benign calcifications in histopathologically confirmed 24 cases. In two patients, mapping studies and paraffin block mammographic examinations were done to correlate calcification on mammography with histopathologic morphology. RESULT: On histopathology, malignant calcifications were located in ductal lumen, while benign ones were usually located in ductal epithelium(p<0.05). However, associated three benign lesions of the 10 malignant lesions showed still benign calcifications adjacent to proven cancer. The typical malignant calcifications were the shape of lamination, while benign calcifications showed granular and salty on light microscope. In 2 mapping studies, malignant-looking calcifications within the area of predominant benign calcifications yielded atypical ductal hyperplasia. Mammographic pepper, granular, punctate, salty and S-shaped calcifications were correlated with granular and salty calcification on light microscope. Mammographic linear, branching, comma, tadpole and wormiform calcifications were correlated with histopathologic laminated calcification. CONCLUSION: Authors have recognized about characteristics of malignant Vs. benign clustered microcalcifications on histopathology. Authors concluded that if malignant-looking calcification such as linear, branching, comma, tadpole and wormiform are present in an are a of predominant benign calcifications, specimen radiographic correlation and mapping study will be necessary for better demonstration of the atypical ductal hyperplasia, hidden or associated breast cancer.

Brachycephaly is a kind of craniosynostosis. Because of premature closure of the coronal suture, the skull is shorter in the anteroposterior diameter but is widened with a high vault and the occiput and forehead are flattened. Diabetes insipidus had been reported in oxycephaly. We have experienced a case of central diabetes insipidus associated with brachycephaly. A brief review of related literatures is included in this report.

Eccrine nevus is an unusual entity with various clinical manifestations. Histologically the eccrine apparatus appears simply increased in number and/or size, but structurally normal. We present a case of eccrine nevus on the dorsum of the left 3rd and 4th fingers in a 20 year-old female. The lesions were 3 × 2cm sized, well demarcated, smooth surfaced, brownish plaques with mild hyperhidrosis. Histological examination revealed hyperkeratosis in the stratum corneum and hyperpigmentation of basal layer, and an increased number of eccrine sweat glands and many eccrine coils in the dermis was seen.

Albinism is an inherited ongenital disarder in which there is sgr neralized decrease or absence of pigrnent in the eyes, skin, and hair. There are two general groups (1) Oculocutneou albinism, (2) Ocular albinism. Skin cancers in albinos are rare in ternperate clirnats and t.hey occur rnostly on sun ex posed areas. We present a case of recurrance of squarnous cell carcinoma ir a Korean albinoid on both sides of the neck and right ear. On liistopathologic examination, we find I or pearls, and irregular mases of epidermal cells that proliferite downward into the devmis. The invaing cell masses are composed of atypical squamous cells.
