Breast cancer and lung cancer are the two most common malignancies in China. With the continuous improvement of breast cancer diagnosis and treatment technology, the survival time of breast cancer patients has been prolonged, and the number of breast cancer patients with second primary lung cancer (SPLC) has increased. In addition, breast cancer is the most common primary cancer in female patients with SPLC, and SPLC is the main cause of death in this population. More and more physicians pay attention to this clinical phenomenon. This paper summarized the risk and risk factors of SPLC in breast cancer patients, and elaborated its pathogenesis, in order to provide a theoretical basis for the clinical management of breast cancer patients and achieve accurate early intervention as soon as possible.

We report here on the multiple genital tract neoplasms in a 41-yr-old Korean woman with Peutz-Jeghers Syndrome (PJS). The patient presented with lower abdominal pain. Her previous medical history was PJS and breast cancer. Pelvic ultrasound showed a multilocular cyst at the right adnexal region, diagnosed as bilateral ovarian mucinous borderline tumors. An ovarian sex cord tumor with annular tubules was incidentally diagnosed together with a minimal deviation adenocarcinoma of the uterine cervix and mucinous metaplasia of both the Fallopian tubal mucosa and the endometrium. Although the cases of multiple genital tract tumors with PJS has rarely been reported, the present case appears to be the first in Korea in which the PJS syndrome was complicated by multiple genital tract tumors and infiltrating carcinoma of the breast. The clinical significance of the multiple genital tract tumors and breast cancer associated with PJS is reviewed.

INTRODUCTIONPathological pulmonary hernia is a rare clinical entity which can be caused by malignancies.

CLINICAL PICTUREA 72-year-old female presented with a painful bulge in the left 4th intercostal space. Chest radiography and computed tomography demonstrated a left pulmonary hernia, pleural effusion and destruction of ribs.

TREATMENTThe hernia sac was excised and a part of the chest wall was resected with reconstruction of residual defect.

OUTCOMEThe patient died 2 years after the treatment.

CONCLUSIONSA multidisciplinary approach involving various medical specialists may offer patients with pathological pulmonary hernia remarkable palliation and better quality of life.

In this paper, we evaluate the radiological features of pregnancy-associated breast lesions and discuss the difficulties in diagnosis by imaging. We selected patients who were diagnosed with pregnancy-associated breast lesions during the previous 5 years. All patients complained of palpable lesions in the breast and underwent ultrasonographic (US) examination, the first choice for examination of pregnancy-related breast lesions. Any suspicious lesions found by the US were recommended for a US-guided core biopsy, US-guided fine needle aspiration (FNA), or surgery. Various breast lesions were detected during pregnancy and lactation, including breast cancer, mastitis and abscesses, lactating adenoma, galactoceles, lobular hyperplasia, and fibroadenomas. The imaging features of pregnancy-associated breast lesions did not differ from the features of non-pregnancy-associated breast lesions; however, some pregnancy-associated benign lesions had suspicious sonographic features. A US-guided core biopsy was necessary for differentiating benign from malignant. In patients with breast cancer, the cancer was often advanced at the time of diagnosis. In conclusion, various pregnancy-related breast lesions were detected and the imaging of these lesions had variable findings. Breast ultrasound could be an excellent imaging modality for diagnosis and differentiation between benign and malignant lesions. However, when the imaging results are suspicious, a biopsy should be performed to obtain a pathologic diagnosis.

Axillary breast is one of the varieties of polymastia which is characterized by the presence of more than 2 breasts. It may cause symptoms during pregnancy, lactation, or in the premenopausal period. Unless there are obvious symptoms of lactation or the assistance of further imaging studies such as mammography and breast ultrasound, the diagnosis is often confused with subcutaneous lipoma. The incidence of axillary breast cancer is low but it should be investigated and treated properly in view of another breast cancer in the embryonic milk-line. In this paper we reviewed 4 cases of axillary breast cancer and documented some articles regarding aberrant breast and carcinoma arising from it. It is suggested that subcutaneous nodules of uncertain origin around the periphery of the breast should be viewed with suspicion and treated properly.

Cowden's disease, also known as various hamartomatous malformations of multiple organs, is a rare autosomal dominant disorder. The most important feature of Cowden's disease is its frequent association with malignant neoplasm, particularly in the breast and thyroid gland. Cowden's disease with malignant neoplasms, is quite rare in Korea so far. We report a case of Cowden's disease associated with breast cancer in a 41-year-old female who underwent routine health cheek-up.

Objective: To investigate the histopathological and immunohistochemical characteristics of benign apocrine cystic papillary hyperplasia of the breast with loss of myoepithelial cell layer. Methods: The clinical data, histopathological features and immunohistochemical profile of patients with benign apocrine cystic papillary hyperplasia of breast with loss of myoepithelial cell layer from January 2016 to December 2021 were examined, in which six patients were identified. Results: All six patients were female, aged 36-61 years (median 46 years), who presented with a breast mass; three cases were from the left breast and three cases were from the right breast. Microscopic examination of all cases showed breast hyperplasia with apocrine cysts, accompanied by different degrees of micropapillary and papillary hyperplasia of apocrine cells. One case was associated with lobular carcinoma in situ, and one case was associated with apocrine ductal carcinoma in situ with intraductal dissemination in adenosis. Immunohistochemical staining of CK5/6, p63, SMA, SMMHC, Calponin and CD10 showed complete absence of myoepithelial cell layer surrounding ducts in apocrine cystic papillary hyperplasia. Conclusions: The myoepithelial cells of apocrine cystic papillary hyperplasia of the breast may undergo abnormal changes and may even be completely lost. The diagnosis should be comprehensively considered along with cytomorphological and histological features to avoid overdiagnosis.

Breast cancer developing from a surgical scar is rare; this type of malignancy has been reported in only 12 cases to date. Herein, we report on a 52-year-old female who developed infiltrating ductal carcinoma in a surgical scar following excision of a benign mass. Two years previously, the patient underwent surgery and radiotherapy for invasive ductal carcinoma of the contralateral breast. The initial appearance of the scar was similar to fat necrosis; it was observed to be progressively shrinking on follow-up sonography. On the two year follow-up ultrasound, the appearance changed, an angular margin and vascularity at the periphery of the scar were noted. A biopsy and subsequent excision of the scar were performed; the diagnosis of infiltrating ductal carcinoma of the scar was confirmed.

BACKGROUNDThe purpose of this study was to investigate the feasibility of avoiding axillary lymph node dissection (ALND) for patients with only one sentinel lymph node (SLN) metastasis. The characteristics and predictive factors for non-sentinel lymph node (NSLN) metastasis of patients with single positive SLN were also analyzed.

METHODSPatients with no and only one SLN metastasis (0/n and 1/n group, n ≥ 2) were selected from 1228 cases of invasive breast carcinoma, who underwent axillary dissection in Shandong Cancer Hospital between November 1999 and December 2011, to compare the characteristics of NSLN metastasis between them. For the 1/n group, the factors that influenced the NSLN metastasis were analyzed by univariate and multivariate analysis.

RESULTSDifferences of the NSLN metastasis between the 0/n and the 1/n groups were significant (P < 0.001). There was no significant difference between the axillary lymph node metastasis on level III in 1/n group and 0/n group (P = 0.570). When the total SLN number was ≥ 4 and with one positive case, the NSLN metastasis was not significantly different from that in the 0/n group (P = 0.118). In the 1/n group, clinical tumor size (P = 0.012), over-expression of Her-2 (P = 0.003), tumor grade (P = 0.018) and the total number of SLN (P = 0.047) significantly correlated with non-SLN metastasis. Clinical tumor size (P = 0.015) and the expression of Her-2 (P = 0.01) were independent predictive factors for non-SLN metastasis by the Logistic regression model.

CONCLUSIONUnder certain conditions, breast cancer patients with single SLN metastasis could avoid ALND.

OBJECTIVETo evaluate and compare localization by ductoscopy-guided wire with localization by conventional methods in the terminal duct excision for women with pathological nipple discharge.

METHODSBreast terminal duct excision were performed in 174 consecutive patients with intraductal lesions diagnosed by mammary ductoscopy. Sixty-eight of those underwent ductoscopy-guided wire localization for more accurate ductal excision. The patients received mammary ductoscopy and a hooked wire was anchored at the intraductal lesions under endoscopic surveillance just before the operation. Then a biopsy resection of wire-guided terminal duct and frozen section were done. Tbe other 106 patients received terminal duct excision under localization with conventional methods without ductoscopy either by puncturing a needle or injection of blue dye through the duct with pathological discharge.

RESULTSOf the 68 patients with ductoscopy-guided duct excision, 64 had intraductal papillomas and 4 duct carcinoma in situ proved by pathology. All the lesions in these 68 patients were completely resected during biopsy without extra extended resection, and the concordance rate of the pathological result with ductoscopic diagnosis was 100.0%. None of them developed a postoperative breast distortion. In the conventional method localization group, there were 96 intraductal papilloma, 6 duct carcinoma in situ and 4 adenosis. Only 77.4% of the lesions were excised in the primary biopsy, and 22.6% needed extended resection. The concordance rate of the pathological diagnosis with ductoscopic diagnosis was 96.2%. Twenty-six patients had a deformed breast postoperatively.

CONCLUSIONDuctoscopy-guided wire localization is superior to the conventional localization method in the surgical terminal duct excision for women with spontaneous nipple discharge. It is not only helpful for more accurate localization and resection as well as pathologic sampling, but also is minimally invasive. Further studies are still required and this method may deserve to be popularized.
