Juvenile fibroadenoma in 13-month-old female child

Ultrasonic elastography features of phyllodes tumors of the breast: a clinical research

The purpose of this study was to analyze the ultrasonic elastography features of phyllodes tumors of the breast comparing with fibroadenomas. A retrospective database was queried for the patients diagnosed as phyllodes tumors and fibroadenomas at Sun Yat-sen Memorial Hospital from January 2008 to August 2012. Three hundred and fifty lesions from 323 consecutive patients were included in the study. All the cases were examined by conventional ultrasonography and ultrasound elastography. Ultrasound elastography was used to calculate strain ratio of the lesions with bilateral breast tissue at the same depth as reference. There were 36 phyllodes tumors (27 benign, 8 borderline, 1 malignant) and 314 fibroadenomas (158 the pericanalicular type, 103 the intracanalicular type, 53 other special types). The strain ratio for phyllodes tumors (3.19±2.33) was significantly higher than for fibroadenomas (1.69±0.88) (p<0.05). The Spearman^.s correlation coefficient between strain ratio of ultrasound elastography and pathological groups was significant, with a value of 0.17 (p<0.05). Ultrasound elastography could provide additional information to differentiate phyllodes tumors from fibroadenoma in breast.

Juvenile fibroadenoma of the breast: Treatment and literature review

It is uncommon to find palpable breast masses in young patients. Generally, such masses are benign. Juvenile fibroadenoma is the most frequent benign tumour of the breast. The present report describes a case involving a 17-year-old girl with unilateral right breast hypertrophy, for whom resection and breast reduction was effectively achieved.Resection was combined with an aesthetically pleasing outcome through breast reduction, via a wise pattern of reduction with a superior pedicle.While young patients rarely present with breast masses, the consideration of fibroadenoma in these cases is always warranted. The disconcerting appearance of the breasts for adolescents afflicted by such benign masses underscores the importance of achieving aesthetically optimal outcomes and attaining adequate tumour resection for diagnostic purposes through pathological specimens. In the present case, the young patient underwent a procedure that fulfilled both of these valuable goals through careful pre-operative planning, pedicle selection and skin resection patterns.

Clinical features and prognosis of a unilateral fibroadenoma of the breast in a 16-month-old female

Fibroadenoma of the breast is a common benign disease, occurring mainly in females younger than 30 years of age. Infant fibroadenoma is extremely rare. Here, we report on a 16-month-old female with a 6 month history of unilateral progressive breast enlargement. Upon clinical evaluation, a palpable mass was observed in the upper and outer quarter of the right breast. The single tumor was solid and well circumscribed. Various clinical examinations were performed, including determination of hormone levels, ultrasound, mammography, magnetic resonance imaging, as well as the collection of a fine needle aspiration. The results showed that the sex hormones were present at normal levels. The size of the tumor was approximately 3 × 3 × 3 cm. Enlarged lymph nodes were not detected in the axillary region or any other regions. The tumor was removed surgically and fibroadenoma was diagnosed post-operatively. The patient was followed up for 38 months and no tumor recurrence was observed.

Mammary fibroadenoma in a lamb

A fibroadenoma was diagnosed in the left udder of a 3-month-old female Chios lamb. No recurrence was observed after surgery. Grossly, the tumor had a whitish-gray lobular appearance, and the lobules were interlaced with thin septa. Microscopically, the tumor was composed of proliferating fibroepithelial tissue, including differentiated ducts lined by whorls and interlacing bundles of abundant loose fibrovascular stroma. Immunohistochemistry revealed the ductal epithelium to be positive for pancytokeratin (AE1/AE3) and loose fibrovascular stroma was positive for vimentin and basal cells covering the ductal epithelium of alpha-smooth-muscle actin. Immunostaining for the estrogen and progesterone receptors was negative. A diagnosis of mammary fibroadenoma was made based on the histological and immunohistochemical findings.
