Ovarian cancer is generally primary cancer and less frequently originates from metastasis from non-gynecological cancer. Ovarian metastasis from lung cancer represents only 2~4% of all ovarian metastatic cancers. We report a case of ovarian metastasis of non-small cell lung cancer with epidermal growth factor receptor mutation. The patient underwent cytoreductive surgery for the ovarian mass and erlotinib therapy for the metastatic lung cancer. Erlotinib therapy markedly decreased the size of lung mass.

Radiation recall dermatitis refers to an acute inflammatory reaction in a previously irradiated field triggered by the administration of certain drugs days to years after the exposure to radiation. Gefitinib is an epidermal growth factor receptor tyrosine kinase inhibitor and is an effective treatment for patients with advanced stage of non small cell lung cancer (NSCLC). Here, we report a rare case of gefitinib induced radiation recall dermatitis. A 52-year-old woman with a metastatic NSCLC had received a palliative radiation therapy of 20 cGy on spine metastasis area (C6-T6). After 24 days of receiving radiation therapy, she had started to take gefitinib. Eight months after taking drug, pain, swelling and erythema of skin were occurred on previously irradiated field. These symptoms were resolved after the cessation of gefitinib for 6 days and the topical use of steroid.

Small cell lung cancer accounts for about 20% of all lung cancers. At the time of diagnosis, the majority of patients already have metastasis. The liver is one of the most common sites of distant metastasis of lung cancer. Small cell lung cancer arises from neuroendocrine cells which produce hormone, hormone producing granules can be seen under electron microscope . A 65-year-old male was admitted to hospital because of jaundice and right upper quadrant pain. The chest roentgenogram and chest computed tomography(CT) scan showed a 3 cm mass in right upper lobe with bilateral mediastinal lymphadenopathy and right pleural effusion. The abdomen CT scan revealed multiple masses in the liver with heterogenous pattern suggesting metastatic orgin. Though the immunohistochemistry and electron miscroscopy, he was diagnosed as metastatic small cell lung cancer of liver. We report a case of the Immunohistochemical and Electron Microscopic Observation of Metastatic Small Cell Lung Cancer of Liver.

We report a case of extensive stage SCLC with EAS confirmed by immunohistochemical stain of ACTH in tumor cells who died early due to rapidly progressive acute respiratory distress and pneumonia before the start of chemotherapy and corticosteroid blocking agent. Through our case, we learn how important early diagnosis and treatment of EAS associated with SCLC are and hope to apply to other cases from now on.
