Accessory axillary breast tissue has received little attention in the surgical literature although it is not an uncommon kind of aberrant breast tissue. Twenty-six patients who have been treated with an exicision of accessory breast tissue from January 1988 to June 1995 at the Department of Surgery, College of Medicine, Soonchunhyang University were analyzed retrospectively. The age of the patients ranged from 18 to 58 years, median age, 34 years. All were female including two postmenopausal females. We observed a palpable mass in the left axillae in 6 patients, in the right axillae in 8 patients and in the both axilla in 12 patients. Of the 41 masses of 26 patients, 19 masses were located on tne anterior axillary line, 20 masses on the midlle axillary line and 2 masses on the posterior axillary line. The size of the accessory breast tissue ranged from 0.5 to 8cm, with a median of 3.4cm. The presenting symptoms were mass in all cases, pain in 12 cases, growing mass in 4 cases and redness in one case. Histological diagnosis of total 41 masses revealed 28 normal breast tissue, 9 fibrocystic disease, 1 ductal ectasia, 1 fibroadenoma, 1 fibrocystic disease with ductal ectasia and 1 infiltrating ductal carcinoma. There were no typical clinical characteristics for differential diagnosis preoperatively. Of a total of 38 excisional operations, 4 complications developed (two hematoma, one wound infection and one skin tag). The postoperative hospital stay ranged from 1 to 17 days. The accessory breast tissue might be regarded as a more important disease than before, because various pathologic changes could occur in it including malignant change. Early diagnosis and correct excision are usually recommended.

OBJECTIVE: In order to elucidate the retrogressive degeneration of orofacial cleft, the fissured tissues of prenatal and postnatal cleft lip and palate were examined by histological and immunohistochemical methods. DESIGN: Totally 42 cases of prenatal (n=17) and postnatal (n=25) cleft lip and/or palate were examined in comparison with 10 cases of normal lip and oral mucosa using immunohistochemical stainings of MMP-3, MMP-9, MMP-10, cathepsin G, PCNA, E-cadherin, TGase 2, HSP-70, vWF, and VEGF. MAIN OUTCOME MEASURES: In the fissured tissue the sebaceous glands were strongly positive for PCNA and grew into the underlying fibromuscular tissue (24/42). Some hyperplastic sebaceous glands of prenatal cleft lip produced infundibular follicular cyst (9/17). The skin and mucosal epithelia from the postnatal cleft lip and palate (10/25) showed severe basal hyperplasia (11/25) and melanocyte infiltration (7/25). RESULTS: The immunostaining of MMP-3 and HSP-70 were strongly positive in the hyperplastic sebaceous glands and nearby atrophying muscle bundles of the fissured tissue, while MMP-9, MMP-10, and cathepsin G were almost negative. The immunoreactions of the other antibodies used in this study were similar between in the fissured tissues and in the normal controls. CONCLUSIONS: These data suggest that the over-expression of MMP-3 is closely related to the sebaceous gland hyperplasia, epithelial dysplasia, and the muscle degeneration, and that the over-expression of MMP-3 in the fissured tissue may continuously aggravate the cleft condition in the later life.

Diabetic mastopathy is a rare disease that occurs in long-term insulin-dependent diabetic patient. It manifests as a hard palpable breast mass that may be clinically indistinguishable from a breast carcinoma. Mammography shows a non-specific, dense, heterogenous glandular opacity in both breasts. Sonography shows a markedly hypoechoic, ill-marginated mass with a posterior acoustic shadowing. We present the mammography, ultrasonography and MRI findings of a 54-year-old woman with diabetic mastopathy.

Background/Aims: South Korean soldiers are exposed to similar environmental factors. In this study, we sought to evaluate the gut microbiome of healthy young male soldiers (HYMS) and to identify the primary factors influencing the microbiome composition. Methods: We prospectively collected stool from 100 HYMS and performed next-generation sequencing of the 16S rRNA genes of fecal bacteria. Clinical data, including data relating to the diet, smoking, drinking, and exercise, were collected. Results: The relative abundances of the bacterial phyla Firmicutes, Actinobacteria, Bacteroidetes, and Proteobacteria were 72.3%, 14.5%, 8.9%, and 4.0%, respectively. Fifteen species, most of which belonged to Firmicutes (87%), were detected in all examined subjects. Using cluster analysis, we found that the subjects could be divided into the two enterotypes based on the gut microbiome bacterial composition. Compared with enterotype 2 subjects, subjects classified as enterotype 1 tended to be characterized by higher frequencies of potentially harmful lifestyle habits (current smoker: 55.6% vs 36.6%, p=0.222; heavy drinker: 16.7% vs 3.7%, p=0.120; insufficient physical activity: 27.8% vs 14.6%, p=0.318). We identified a significant difference in the microbiome compositions of current and noncurrent smokers (p=0.008); the former differed from the latter mainly in a relatively lower abundance of Bifidobacterium species and a higher abundance of Negativicutes. Conclusions A high abundance of Actinobacteria and low abundance of Bacteroidetes
