ABSTRACT

Background/Aims@#We evaluated the efficacy of docetaxel and epirubicin as neoadjuvant chemotherapy in locally advanced breast cancer and assessed the predictive factors for response to neoadjuvant chemotherapy and prognostic factors related to relapse-free survival. @*Methods@#Forty patients who received docetaxel and epirubicinas neoadjuvant chemotherapy for locally advanced breast cancer were evaluated retrospectively. Neoadjuvant chemotherapy consisted of intravenous injection of 75 mg/m2 docetaxel and 60 mg/m2 epirubucin on day 1, every 21 days, and two to six cycles. @*Results@#Twenty-five (62.5%) patients showed a partial response, and 15 (37.5%) patients showed a stable disease in the first response evaluation after two or three cycles of neoadjuvant chemotherapy. In the second response evaluation of nine patients who received six cycles of neoadjuvant chemotherapy, one patient achieved a complete response, but two patients with hormone receptor-negative, human epidermal growth factor receptor 2-positive breast cancer experienced disease progression. Twenty-five (62.5%) patients experienced downstaging after neoadjuvant chemotherapy. Patients with > 20% pretreatment Ki-67 and decrease of Ki-67 between pre- and post-neoadjuvant chemotherapy showed a trend for better response. In multivariate analysis, advanced pathological stage showed a significant negative effect on relapse-free survival. @*Conclusions@#Docetaxel and epirubicin neoadjuvant chemotherapy showed a good response in locally advanced breast cancer. Pretreatment Ki-67 and change of Ki-67 may play a role as predictive factor for response to neoadjuvant chemotherapy.

ABSTRACT

PTEN hamartoma tumor syndrome is a spectrum of disorders characterized by unique phenotypic features including multiple hamartomas caused by mutations of the tumor suppressor gene PTEN. Cowden syndrome and Bannayan–Riley–Ruvalcaba syndrome are representative diseases, and both have several common clinical features and differences. Because PTEN mutations are associated with an increased risk of malignancy including breast, thyroid, endometrial, and renal cancers, cancer surveillance is an important element of disease management. We report a germline mutation of the PTEN (c.723dupT, exon 7) identified in a young woman with a simultaneous occurrence of breast cancer, dermatofibrosarcoma protuberans, and follicular neoplasm. This case suggests that it is critical for clinicians to recognize the phenotypic features associated with these syndromes to accurately diagnose them and provide preventive care.

ABSTRACT

We present image findings, especially rare MRI of a primary breast angiosarcoma with its histopathology, and also analyze the relevant medical literature reports in terms of the MRI findings. As our patient had unique features of a primary breast angiosarcoma, this case could be very helpful for future diagnosis of this rare breast malignancy by MRI.

ABSTRACT

OBJECTIVE: To evaluate the sonographic features of invasive apocrine carcinoma (IAC) of the breast. MATERIALS AND METHODS: This study included five pathologically proven cases of IAC, and their sonographic features were retrospectively analyzed according to the Breast Imaging Reporting and Data System (BI-RADS) lexicon. RESULTS: All five lesions involved the left breast and were seen as irregularly shaped masses. All lesions, except one, had a parallel orientation to the chest wall. All five lesions showed noncircumscribed margins and heterogeneous echotexture; however, they showed various posterior features. One lesion had edema as an associated feature. Sonographic assessments were classified as BI-RADS category 4 in all five cases. CONCLUSION: Invasive apocrine carcinoma sonographic findings are difficult to differentiate from those of invasive ductal carcinoma of no special type.

ABSTRACT

Focal neuroendocrine differentiation can be found in diverse histological types of breast tumors. However, the term, neuroendocrine breast tumor, indicates the diffuse expression of neuroendocrine markers in more than 50% of the tumor cell population. The imaging features of neuroendocrine breast tumor have not been accurately described due to extreme rarity of this tumor type. We present a case of a pathologically confirmed, primary neuroendocrine breast tumor in a 42-year-old woman, with imaging findings difficult to be differentiated from that of invasive ductal carcinoma.

ABSTRACT

The purpose of this paper is to show the clinical and radiologic features of a variety of diffuse, infiltrative breast lesions, as well to review the relevant literature. Radiologists must be familiar with the various conditions that can diffusely involve the breast, including normal physiologic changes, benign disease and malignant neoplasm.

ABSTRACT

A tumoral pseudoangiomatous stromal hyperplasia (PASH) that causes huge breast enlargement is very rare. Only two cases of huge tumoral PASHs have been reported in the English medical literature. We report here on a surgically confirmed case of bilateral huge tumoral PASH in a 47-year-old woman, and we present the imaging and histopathology findings. We also review the relevant medical literature.

ABSTRACT

Eosinophilic enteritis is an uncommon disease that rarely manifests as an acute abdomen. A 50-year-old man visited our hospital and complained of epigastric and periumbilical pain. He reported direct and rebound tenderness over the periumbilical area. Laboratory examinations showed leukocytosis without eosinophilia. Plain abdominal radiography revealed air-fluid levels in the small intestine and computed tomography revealed concentric wall thickening in the small bowel and ascites in the pelvic cavity. We conducted an emergency operation and segmental resection of the jejunum was performed. Histologically, transmural, eosinophilic infiltration was observed. In patients with intestinal obstruction, even when presenting with an acute abdomen with no peripheral eosinophilia, eosinophilic enteritis should be included in the differential diagnosis.

ABSTRACT

OBJECTIVE: This study was designed to evaluate the ultrasonographic (US) findings of medullary thyroid carcinoma (MTC) as compared to findings for papillary thyroid carcinoma (PTC). MATERIALS AND METHODS: The study included 21 cases of MTC that were surgically diagnosed between 2002 and 2007 and 114 cases of PTC that were diagnosed in 2007. Two radiologists reached a consensus in the evaluation of the US findings. The US findings were classified as recommended by the Thyroid Study Group of the Korean Society of Neuroradiology and Head and Neck Radiology (KSNHNR) and each nodule was identified as suspicious malignant, indeterminate or probably benign. The findings of medullary and papillary carcinomas were compared with use of the chi-squared test. RESULTS: The common US findings for MTCs were solid internal content (91%), an ovoid to round shape (57%), marked hypoechogenicity (52%) and calcifications (52%). Among the 21 cases of MTC nodules, 17 (81%) were classified as suspicious malignant nodules. The mean size (longest diameter) of MTC nodules was 19 +/- 13.9 mm and the mean size (longest diameter) of PTC nodules was 11 +/- 7.4 mm; this difference was statistically significant (p < 0.05). An ovoid to round shape was more prevalent for MTC lesions than for PTC lesions (p < 0.05). CONCLUSION: The US criteria for suspicious malignant nodules as recommended by the Thyroid Study Group of the KSNHNR correspond to most MTC cases. The US findings for MTC are not greatly different from PTC except for the prevalence of an ovoid to round shape.

ABSTRACT

PURPOSE: We wanted to evaluate the value of intravenous contrast enhanced abdomen-pelvis computed tomography (CT) for diagnosing acute appendicitis and we wanted to determine which patients groups will benefit from preoperative CT. METHODS: Between January and June 2006, the medical records of 354 patients who had clinically suspected acute appendicitis were retrospectively reviewed. Appendectomy was performed in 260 patients and CT was conducted in 108 patients of the 260 patients. The 5mm slice CT scans were evaluated for the presence of appendicitis. The sensitivity, specificity and accuracy of CT were calculated. The negative appendectomy rate (NAR) was compared between the patients with CT scans and those without CT scans. Furthermore, the patients were classified into the children and adults groups and the male and female groups and the differences of the NARs were analyzed for each group. RESULTS: The sensitivity, specificity and accuracy were 95%, 93% and 94%, respectively. The NAR was lower for the patients with a CT scan (12%) compared to 27% for those patients without CT scans (P=0.002). The difference of the NAR between the preoperative CT group and the without CT group was statistically significant for the female (P=0.004) and adult groups (P=0.012) (14% vs 36%, 11% vs 26%, respectively). CONCLUSION: Preoperative intravenous contrast enhanced abdomen-pelvis CT was effective in reducing the negative appendectomy rate in patients who were suspected of having acute appendicitis. Especially, the adults and women benefit more from CT scanning and they had a significantly lower negative appendectomy rate than the children and men, respectively.

ABSTRACT

Epidermal inclusion cyst of the breast is an uncommon benign lesion and it is usually located in the skin layer. We report here on two cases of ruptured epidermal inclusion cysts in the subareolar area, which is a very unusual location for these cysts and these lesions can be mistaken for breast malignancies.

ABSTRACT

A paraffin injection is regarded as to be a simple and effective method of breast augmentation. However, there are few reports on the long-term complication of a paraffin injected breast. The generation of breast cancer from a paraffinoma of the breast is rare, even though there is no clear evidence to suggest any relationship between a paraffin injection and breast cancer. We encountered a case of infiltrative ductal carcinoma arising from paraffinoma tissues. A 49-year-old woman had undergone bilateral breast augmentation by paraffin injection 20 years earlier. She presented with bilateral diffuse painless palpable masses with reddish discoloration and painful swelling in her left breast. She had been managed with a bilateral simple mastectomy including the mass. After discharge, the pathology report showed infiltrative ductal carcinoma of the left breast mass. The patient was readmitted for additional surgery, and she underwent a modified radical mastectomy. Ultrasonography is a useful diagnostic tool for detecting a breast mass, particularly in a dense breast. However, ultrasonography has a limitation in the case of a paraffinoma. Through this case, it is necessary to review the radiological (mammography, ultrasonography, magnetic resonance imaging, plain film) appearances and the histopathological feature to help make an accurate diagnosis and to differentiate between a carcinoma and a paraffinoma. In rare cases, a breast ductal carcinoma can be combined with a paraffinoma. Therefore, a paraffinoma must be carefully managed due to the potential risk of a carcinoma.

ABSTRACT

Leiomyomas most frequently occur in the genitourinary and gastrointestinal system. This report describes the clinical and imaging findings of a leiomyoma originating in the prevesical space, a rare location. The mass abutted the fundus of the uterus, but after the correct identification of feeding vessels from the right iliac artery, prevesical leiomyoma was diagnosed radiologically.
