Comparison of rate of development and rate of change for benign and malignant breast calcifications at the lumpectomy bed.

OBJECTIVE: The study purpose was to evaluate the rate of development and the rate of change for benign and malignant breast calcifications at the lumpectomy bed. MATERIALS AND METHODS: Retrospective review identified 53 new calcifications at the lumpectomy bed in patients with available mammograms and medical records. Breast Imaging Reporting and Data System (BI-RADS) categories were retrospectively assigned on the basis of initial prospective recommendation for yearly follow-up (category 2), 6-month follow-up (category 3), or biopsy (category 4 or 5). Outcomes were defined as benign for no recurrence at the lumpectomy bed on biopsy or follow-up and malignant if biopsy-proven at the lumpectomy bed. RESULTS: The median rate of development after lumpectomy was 23 months (range, 2-174 months) for benign and 39 months (range, 15-112 months) for malignant calcifications. Fifteen (28%) of 53 calcifications were classified as BI-RADS category 3. Twelve (80%) of 15 were downgraded to BI-RADS category 2 at a median follow-up of 6.5 months (range, 6-16 months); none represented recurrent disease. Three (20%) of 15 were upgraded to BI-RADS category 4 at the 6-month follow-up, one despite stability (benign) and two for increasing pleomorphism (malignant). Nine (17%) of 53 calcifications were classified as BI-RADS category 4 or 5; six (67%) of the nine were malignant and three (33%) were benign at biopsy. Twenty-nine (55%) of 53 calcifications were classified as BI-RADS category 2, none representing recurrent disease. CONCLUSION: Benign calcifications at the lumpectomy bed usually develop earlier than malignant calcifications, but the rate of development overlaps. Most calcifications initially placed in the probably benign category evolve quickly to more benign or more malignant morphology. Most calcifications heralding recurrence appear suspicious on first presentation.

Local tumor recurrence following breast-conservation therapy: correlation of histopathologic findings with detection method and mammographic findings.

PURPOSE: To correlate histopathologic findings with detection method and mammographic appearance in primary and locally recurrent breast carcinoma after breast-conservation therapy. MATERIALS AND METHODS: Medical records and mammographic findings were retrospectively reviewed; 26 patients with 27 local recurrences after breast-conservation therapy were identified. RESULTS: Primary histopathologic findings included six in situ and 20 invasive carcinomas. Of the 27 recurrences, 19 (70%) were at or adjacent to the lumpectomy site and eight (30%) were elsewhere in the breast. All primary ductal carcinoma in situ (DCIS) cases manifested mammographically as microcalcifications and recurred as DCIS with microcalcifications. Eleven primary invasive carcinomas (10 masses, one case of microcalcifications) were detected only mammographically, three were detected only with physical examination, and six (six masses) were detected with both. Among these 20 recurrences, 14 (five masses, nine cases of microcalcifications) were detected only mammographically, one was detected only with physical examination, and five (five masses) were detected with both. Seventeen (85%) of 20 primary invasive carcinomas recurred invasively: 16 (94%) with similar histopathologic findings and eight (47%) with similar mammographic findings. CONCLUSION: In local recurrence after breast-conservation therapy for DCIS, histopathologic findings, detection method, and mammographic findings are usually similar. Histopathologic findings of primary invasive breast carcinoma and local recurrence are usually similar, but the detection method and mammographic findings vary. This is relevant to the interpretation of new clinical or mammographic findings following lumpectomy.

Retroareolar breast carcinoma: clinical, imaging, and histopathologic features.

PURPOSE: To evaluate the clinical, imaging, and histopathologic features of breast carcinoma in the retroareolar tissues and to determine whether there are any characteristics common to this location. MATERIALS AND METHODS: Thirty-five patients (age range, 38-77 years) with 37 retroareolar carcinomas were identified retrospectively. Retroareolar carcinoma was defined as that within 2 cm of the nipple-areolar complex. Mammographically occult tumors were identified by using histopathologic records (n = 4) or clinical examination findings (n = 6). RESULTS: Twenty-nine (78%) tumors had clinical findings, including palpable mass (n = 29), associated nipple inversion or retraction (n = 4), and associated nipple discharge (n = 2). Twenty-seven (73%) tumors had mammographic findings of mass (n = 16), mass with calcifications (n = 5), and microcalcifications (n = 6; four of these microcalcifications were associated with a mammographically occult palpable mass). Ultrasound was performed in 17 tumors, all of which were hypoechoic. The stage of 31 carcinomas was known: one was stage 0, 17 were stage I, and 13 were stage II. Histopathologic analysis revealed 35 ductal carcinomas and two invasive lobular carcinomas. CONCLUSION: Retroareolar carcinoma usually manifests as a palpable mass. Mammography is less sensitive in this area than in other areas of the breast. Ultrasound can be a valuable adjunct in the assessment of retroareolar malignancy.

A technique for developing and photographing ridge impressions on decomposed water-soaked fingers.

One of the most challenging tasks confronting a crime laboratory technician is the fingerprinting and subsequent identification of an unknown homicide or drowning victim whose fingers have been subjected to a long period of exposure to water and the effects of decomposition. If the fingers of the individual have not been exposed to the erosive effects of water and decomposition for a long period of time, they may be allowed to dry, and suitable impressions are often obtainable. In other cases the fingers may have to be removed, with the permission of the Medical Examiners Office, and processed by the Crime Laboratory in an attempt to develop suitable ridge structure for inked impressions or an exact photographic copy of the individual's fingers. In extreme cases the effects of water and decomposition make the fragile ridge structure appear to be nonexistent to the naked eye. The procedure used in this case report, combines the use of cyanoacrylate vapor, commonly called "super glue fuming," and the ninhydrin process in conjunction to develop fragile ridge structure into discernable ridges that are easily seen and photographed for the purpose of making an identification of the individual.
