It is well known that the medullary carcinoma of the breast is one of the special types of breast carcinoma with a good prognosis. At present, the medullary carcinoma of the breast is subclassified into 3 types: typical medullary, atypical medullary and nonmedullary carcinoma. Among them, the former has the best prognosis. We reviewed the film mammographic and ultrasonomammographic findings of 13 patients according to the reevaluated histopathologic diagnosis. Typical medullary carcinoma shows a well circumscribed mass with surrounding halo on film mammogram, and well defined mass with central intermediate echogenicity and peripheral low echogenicity and posterior acoustic enhancement on ultrasonomammogram. Atypical medullary carcinoma shows relatively well circumscribed mass with partial marginal obliteration on film mammogram, and irregular bordered mass with inhomogeneous echogenicity due to focal necrosis in the mass and associated findings of thick boundary, asymetrical lateral shadowing on ultrasonomammogram. Nonmedullary carcinoma shows lobulated mass with surrounding parenchymal distortion and skin thickening on film mammogram, and relatively well defined lobulating mass with surrounding parenchymal distortion and marked heterogeneous internal echogenicity on ultrasonomammogram. Therefore, differentiation between typical medullary carcinoma with good prognosis and atypical medulary or nonmedullary carcinoma with poor prognosis, may be possible by various diagnostic imaging modalities preoperatively. But further collective study shall be needed in near future.

PURPOSE: To evaluate the ultrasonomammographic findings of breast fibroadenoma. METHODS AND MATERIALS:We evaluated the ultrasonographic findings of histopathologically proved 135 fibroadenomas in 103 patients from January 1986 to September 1990, retrospectively. The ultrasonographic examinations were performed with a hand held linear array 5MHz transducer(Acuson 128(USA). Aloka 650, 280(Japan)). A sonopad was also used during the examinations. RESULTS: The common ultrasonographic findings of fibroadenomas usually showed smooth contour in 120 lesions(88.9% ), oval or round shape in 114 lesions(84.4%), uniform homogeneous echogenecity in 106 lesions(78.5% ), intermediate hypoechoic internal echo pattern in 105 lesions(77.8%), thin boundary echo in 117 lesions(86.7%), lateral shadowings in 97 lesions(72%), and posterior acoustic enhancement in 56 lesions(41%). The longitudinal/transverse ratio of fibroadenoma was revealed between 0.2 and 1.14 (mean 0.58) and usually under 1.0 (68.9%). CONCLUSION: Finally, most of fibroadenomas are easily diagnosed by ultrasonography but if differential diagnosis from malignant breast mass is difficult due to atypical appearance, other combined modalities such as filmmammography, fine needle aspiration biopsy and MRI are necessary.

BACKGROUND: Sometimes, the clinical distinction between early-stage mycosis fungoides and benign inflammatory deimatoses such as psoriasis and dermatitis can be difficult, and it is not uncommon for the histological changes to be non-diagnostic in early-stage mycosis fungoides. Aberrant immunophenotypic expression of T cells occurs frequently in mycosis fungoides, but is uncommon in benign dermatosis. OBJECTIVE: We investigated the distribution and relative numbers of T lyinphocytes and epidermal cells labelled with various monoclonal antibodies in mycosis fungoides, psoriatic, and eczematous lesions by the immunoperoxidase technique. METHODS: Lesional skin tissues were obtained from 7 mycosis fungoides(10 tissues), 9 psoriasis, and 9 eczema patients. Immunohistochemical staining was done on the frozen sections using a labelled streptavidin-biotin-peroxidase complex method with primary antibodies against CD3, CD4, CD5, CD7, CD8, Leu-8, and HLA-DR. RESULTS: The infiltrating cells in mycosis fungoides, psoriatic, and eczematous lesions were uniformly stained with anti-CD3 and most of CD3+ T cells were also stained with anti-CD4. CD 7 expression of T cells was decreased predominantly in mycosis fungoides but loss of CD7 expression was not prominent in psoriatic and eczematous lesions. In the epidermis, HLA-DR was stained extensively in keratinocytes of mycosis fungoides, but only focal staining of HLA-DR was seen in psoriatic and eczematous lesions. CONCLUSION: These findings suggest that CD4+, CD7- T cells and HLA-DR expression of keratinocytes participate in the development of mycosis fungoides, and are helpful in differentiating mycosis fungoides from psoriasis and eczema.
