Lung cancer is the most frequent type of major cancer worldwide. Lung cancer is histopathologically divided into small cell carcinoma and non-small cell lung cancer (NSCLC). In, addition, the discrimination of the histological subtype in NSCLC is regarded as highly important when choosing chemotherapy agents, as their effects differ according to the histological subtype [1]. The 2015 World Heal...

Mucinous tubular and spindle cell carcinoma (MTSCC) is rare in renal cell carcinoma (RCC) and usually demonstrates a low nuclear grade and a better prognosis compared with other RCCs. The authors present a case report of MTSCC containing an area of Fuhrman nuclear grade 3, in addition to an area with a micropapillary pattern. An 82-year-old man consulted a hospital due to macrohematuria, and a ...

BACKGROUND We explored correlations between the new International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society classification, epidermal growth factor receptor (EGFR) mutation status, and prognosis. METHODS Data from 293 patients with lung adenocarcinoma were classified according to the new classification. Fisher's exact, χ2 , and log-rank te...

Multiple cancers represent 2.42% of all human cancers and are mainly double or triple cancers. Many possible causes of multiple malignancies have been reported such as genetic alterations, exposure to anti-cancer chemotherapy, radiotherapy, immunosuppressive therapy and reduced immunologic response. We report a female patient with multiple sclerosis and quadruple cancers of different embryologi...

Atypical ductal hyperplasia (ADH) diagnosed by core needle biopsy (CNB) is regarded as an indication for surgical excision. We investigated whether histologic subtype and extent of ADH in a series of 123 CNB specimens can predict the presence of carcinoma on surgical excision. We found that ADH present in more than 2 foci in CNB specimens was a strong predictor of ductal carcinoma in situ (DCIS...

5573 Background: The aim of this study was to determine prognostic factors in a large series of patients with stage II or III serous low malignant potential ovarian tumor (LMPOT) and peritoneal implants. METHODS A retrospective review of patients with a serous LMPOT and peritoneal implants treated or referred in our institution. The slides of ovarian tumors and peritoneal implants were review...

Carcinoma ex pleomorphic adenoma (CXPA) is an unusual epithelial malignancy that develops from a primary or recurrent pleomorphic adenoma (PA), the most common tumor of salivary glands, and constitutes about 11.5% of all carcinomas that affect these glands. Intraoral minor salivary glands and seromucous glands of the oropharynx are uncommon locations of CXPA. On histopathological examination, t...

Breast metastasis from extra-mammary malignancy is rare. Based on the literature an incidence of 0.4-1.3% is reported. The primary malignancies most commonly metastasizing to the breast are leukemia-lymphoma, and malignant melanoma. We present a case of metastasis to the breast from a pulmonary adenocarcinoma, with extensive micropapillary component, diagnosed concomitantly with the primary tum...
