A Rare Case of Recurrent Myoid Hamartoma Mimicking Malignancy: Imaging Appearances

Myoid hamartoma is an uncommon type of breast hamartoma and its recurrence is very rare. We report the imaging appearance of an unusual case of recurrent myoid hamartoma of the breast mimicking malignancy in a 43-year-old woman. Although the mammographic and ultrasonographic findings have long been described in the literature, MR finding with a dynamic study has not, to the best of our knowledge, been reported previously.     

乳腺黏液腺癌X线摄影表现与病理对照分析

目的探讨乳腺黏液腺癌X线摄影表现的病理学基础。方法回顾性分析30例乳腺黏液腺癌（单纯型19例,混合型11例）的X线摄影表现,并分析其病理特点。结果①乳腺黏液腺癌最常见的x线表现为肿块（25例）,伴或不伴钙化。少见征象为局部不对称性致密影伴钙化（5例）;②单纯型黏液腺癌X线表现多为边缘小分叶,混合型黏液腺癌X线摄影多表现为边缘浸润,两者差异有统计学意义;③肿块的形状、大小、密度情况在判断黏液腺癌的病理分型上无统计学意义。结论不同亚型的乳腺黏液腺癌的X线摄影表现不完全一致,单纯型黏液腺癌最常见的表现为边缘小分叶的肿块,较少伴钙化;混合型黏液腺癌最常见的表现为边缘浸润的肿块,多伴细小、多形性钙化。     

腋部副乳腺的X线诊断

目的 认识腋部副乳腺的X线表现。方法 回顾性复习了3年来的7562例女性接受日常乳腺X线检查的内侧斜位照片,观察有无副乳腺及其X线表现。诊断依据为：在腋内有和主乳腺不相连的腺体样结构。结果 7562例中发现腋部副乳腺161例,发生率2％,平均年龄39岁。38％发生于两侧,42％发生于右侧,20％发生于左侧。最大径线平均为3．5cm(右）和3．3cm(左）。在形态上,斑片状最多（35％）,其余依次为分支状（26％）、混合状（20％）及团片状（19％）。3例手术病理证实为乳腺组织。结论 腋部副乳腺不少见,有一定的X线表现,认识它很重要,以避免将此种发育异常误认为其他病变。     

Fatty tissue breast lesions

Hamartoma, lipoma and fat necrosis are benign fatty tissue lesions that may present as breast lumps. The mammographic appearance may be distinctive allowing imaging diagnosis without biopsy. The characteristic feature of hamartoma is that of a compressible mass containing radiolucent fat interchanged with dense fibrous connective tissue surrounded by a thin radioopaque pseudocapsule. Lipomas are radiolucent with well-defined thin smooth capsule. Twenty-seven percent of fat necrosis appears as discrete round or oval radiolucent oil cyst with thin capsule and egg-shell calcification.     

Mammographic and clinical predictors of drainage patterns in breast lymphoscintigrams obtained during sentinel node procedures

PURPOSE: The authors' purpose was to explore the association between mammographic findings and drainage patterns on lymphoscintigrams obtained during sentinel node procedures for breast carcinoma. MATERIALS AND METHODS: From July 1997 to March 2000, 132 patients with breast cancer who were included in a prospective mammography-pathology correlation and staging database were imaged 2 hours after perilesional injection of 1 mCi filtered (0. 22 microm) Tc-99m sulfur colloid (4 ml volume) before sentinel node procedures. RESULTS: Sixty-four percent of the scans showed axillary drainage only, 9% showed axillary and internal mammary drainage, and 4% revealed internal mammary drainage only. Twenty-three percent of scans showed no drainage. Of the patients who showed drainage, 17% showed drainage to the internal mammary basin, and 5% showed this exclusively. Internal mammary drainage was seen in 18% (10 of 57) of lateral, 21% (6 of 29) of medial, and 14% (1 of 7) of subareolar lesions (P = NS). No drainage was seen in 22% of patients with predominantly fatty mammographic parenchymal density (>50%) compared with only 8% of patients with predominantly dense (>50%) parenchyma (P < 0.05). Failure to show drainage was more common in women older than 50 years (P < 0.05). Axillary sentinel nodes were identified surgically in 73% of patients with negative scan findings. There was no significant association between scintigraphic drainage and mammographic soft tissue tumor size and appearance, histologic findings, or axillary node status. CONCLUSIONS: Dense mammographic parenchyma and age less than 50 years are associated with identification of lymphatic drainage on lymphoscintigrams performed before sentinel node procedures in 91% to 92% of patients. Internal mammary drainage, present in 18% of lateral and 21% of medial lesions, may direct therapy to include internal mammary lymph nodes.     

Breast hamartomas: variable mammographic appearance

The mammograms of 17 women with pathologically proved breast hamartomas were reviewed. Abnormal masses were detected on 12. Nine women had masses with benign features. Two of these had findings considered classic for hamartoma. In three cases, the appearance of the mass was suggestive of carcinoma. The breasts were very dense in four of five women without detectable mass. The findings suggest that the classic mammographic appearance of breast hamartomas is less common than previously reported, which may be explained by earlier detection of small hamartomas.
