Tc-99m methoxyisobutylisonitrile (MIBI) scintigraphy is generally used as a second-line diagnostic tool for obscured breast lesions. When the entire field of view is examined carefully, it is often possible to detect additional lesions unrelated to the initial intent and purpose of the examination. Herein we present a case of breast cancer incidentally detected by cardiac Tc-99m MIBI scintigraphy. An area of uptake was detected in the breast during a cardiac imaging test. Further evaluation of this lesion revealed a histopathological diagnosis of invasive ductal carcinoma of the breast. Sensitivity of this scintigraphic technique is not enough sufficient to use this test as a screening test for breast cancer, but it may provide supplemental information. Since it is not uncommon to find incidental lesions during imaging studies, examination of the image field may help clinicians find otherwise unrecognized or undiagnosed pathologies.

Apocrine carcinoma is an uncommon, poorly characterized type of breast tumor. The histologic characteristics of apocrine epithelium in malignant breast lesion were first noted by Krompecher(1916), while the first detailed description of an apocrine carcinoma is credited to Ewing in 1928. The reported incidence of apocrine carcinoma is approximately 0.4% of breast cancers. Apocrine carcinoma has distinct histologic and ultrastructural features that distinguish it as a specialized form of infiltrating ductal carcinoma. The finding of a uniform pattern of apocrine differentiation with dense granularity typifying the majority of cells characterizes this variant. We experienced two cases of invasive apocrine carcinoma of the breast and report with a review of the related literature.

To make the objective standard of nuclear size in grading nuclear pleomorphism of invasive ductal carcinoma of the breast, we measured maximal nuclear diameter of tumor cells on imprint cytology slides and histologic sections from 65 cases by using computer-based image analysis system (Optimas 6.0). The maximal diameter of red blood cells were also measured to evaluate the ratio of maximal nuclear diameter of tumor cells to maximal diameter of red blood cells. The mean values of maximal nuclear diameter of tumor cells on imprint cytology slides and histologic sections were 7.56microgram, 7.53microgram in nuclear grade 1, 8.92+/-0.98microgram, 9.02+/-0.74microgram in nuclear grade 2, and 12.90+/-1.47prn, 12.44+/-1.41microgram in nuclear grade 3, respectively. There were no significant differences between values of imprint cytology and histologic section. The ratio of maximal nuclear diameter of tumor cells to maximal diameter of red blood cells were 1.3-1.4:1 in nuclear grade 1, 1.6-1.7:1 in nuclear grade 2, and 2.2-2.3:1 in nuclear grade 3. Ths would be guidelines for grading nuclear pleomorphism of invasive ductal carcinoma of the breast on routine surgical pathology work.

PURPOSE: To evaluate the usefulness of stereoscopic localization of nonpalpable breast lesions. MATERIALS AND METHODS: The authors retrospectively analyzed 60 cases of stereotactic localization performed for lesions whichwere mammographically visible but not palpable. Each case was reviewed for chief complaint, indication oflocalization on a mammograph, location of the lesion, pathological diagnosis, and complications during and afterthe procedure. RESULTS: Most patients(75%) had no specific complaint. Among the 60 cases, microcalcification,mass and combined lesions were found in 34(57%), 12(20%), and 14 cases(23%), respectively. The most commonlocation of the lesion was the upper outer quadrant(29 cases). A histopathologic report was available in 56 of 60cases. Among 43 benign cases(76.8%), fibrocystic disease was most common(38 cases, 67.9%), while among 13malignant cases, ductal carcinoma was most common(9 cases, 16.1%). In four of 56 cases(7.1%), failure to removethe target lesion was identified. Retrospective analysis suggests that movement of the patient during theprocedure is the most likely cause of failure. There were no major complications. CONCLUSION: Stereotacticlocalization is simple and accurate, and compared with the conventional method, requires less experience on thepart of the practitioner. Movement of the patient during the procedure may be the major cause of failure.

As a consequence of the incomplete resolution of embryologic mammary ridges, ectopic breast tissue can be present anywhere along the "milk line", including the axillary region. Aberrant breast tissue can develop with any disease that affects the normal breast, including a breast carcinoma. A carcinoma of aberrant breast tissue is rare, but should still be investigated and treated properly with respect to other breast cancers in the embryonic milk-line. Herein is reported our recent experience of a carcinoma originating from aberrant breast tissue in the right axilla. An abnormal nodule around the periphery of the normal breast should be suspected as a breast carcinoma and differential diagnosis and properly treated.

Breast carcinomas are an uncommon neoplastic condition in men, accounting for only 1% of all breast cancers, and less than 1% of all malignancies in men. A 70-year-old man who presented a right breast mass was found to have infiltrating ductal carcinoma. We herein report the case with a review of the literature.
