A 49-year-old woman presented with abdominal pain. A computed tomography scan revealed a left breast mass with suspected peritoneal dissemination. She had no notable family history of the disease. Following a detailed examination, she was diagnosed with ovarian cancer(Stage ⅢC)and left breast cancer(Stage Ⅰ). After confirming the diagnosis of ovarian cancer with a laparoscopic biopsy, neoadjuvant chemotherapy was scheduled. Due to its efficiency in reducing tumor burden, debulking surgery was also performed. While receiving adjuvant chemotherapy for ovarian cancer, concomitant anastrozole was administered for breast cancer. A pathogenic variant of BRCA2 was subsequently identified. Once adjuvant chemotherapy for ovarian cancer had been completed, a left mastectomy and sentinel lymph node biopsy were performed as management for breast cancer. The patient will continue treatment with anastrozole for breast cancer and olaparib for ovarian cancer and will be followed up appropriately.

Ciliated muconodular papillary tumor( CMPT) is a rare true pulmonary tumor consisting of bronchiolar cellular elements. Although this tumor cannot be classified as benign or malignant, it is mostly believed to be a benign bronchiolar adenoma. Recently, CMPT has been divided into two subtypes: proximal and distal. Herein, we report a case of a proximal type of CMPT containing abundant mucus cells in a 70-year-old woman. Thoracoscopic resection of the tumor in the left lower lobe was successfully performed, and the patient has been well without recurrence or metastasis for more than three years after surgery.

Deep femoral artery (DFA) aneurysms are rare. DFA is protected by the adductor canal, which may delay the diagnosis. Then, its early diagnosis may be difficult and it is possible to be misdiagnosis with incarcerated inguinal hernia, which occurs more often in elderly people. We report a very rare case of a treatment of an advanced elderly patient with an isolated ruptured DFA aneurysm that was preoperatively confused with an incarcerated inguinal hernia. A 97-year-old man was admitted to a neighboring hospital due to a painful mass of the right groin after transient consciousness loss and the patient was diagnosed with right incarcerated inguinal hernia by a nonenhanced computed tomography (CT). Although he was observed for 3 days, he suddenly lost consciousness again with a decrease in blood pressure. Thus, he was referred to our hospital due to the painful pulsatile inguinal mass after resuscitation from shock. As we diagnosed a ruptured DFA aneurysm by an enhanced CT, we emergently performed an excision of the aneurysm with revascularization of the right DFA. The postoperative course was uneventful without ischemic change of the lower leg.

A 67-year-old woman who underwent left breast mastectomy and right breast partial mastectomy under the diagnosis of left breast cancer and suspected right breast cancer 10 years earlier was admitted because of dyspnea. Chest computed tomography revealed pericardial fluid accumulation. The patient was treated with pericardial drainage; thereby, 800 mL of bloody fluid was removed. The cytological diagnosis was malignancy. After receiving mitomycin C instillation, she underwent systemic chemotherapy and endocrine therapy. At the last follow-up more than 5 years after the recurrence, no reaccumulation of the pericardial fluid was observed, and she remained alive in good condition.

A 59-year-old male was admitted to our hospital with an abnormal shadow on a chest X-ray. Right pneumonectomy and lymph node dissection (ND2a) were performed. A pathological examination revealed adenocarcinoma( pT3N2M0). Fourteen years later, chest computed tomography(CT) showed a tumor shadow in the lower lobe of the left lung. His pulmonary function was sufficient to allow a 2nd operation. He underwent wedge resection of the lower lobe of the left lung with the assistance of extra corporeal membrane oxygenation (ECMO). His postoperative course was uneventful. A pathological examination revealed large cell neuroendocrine carcinoma, which was 18 mm in diameter. His performance status declined slightly, but he had no problems associated with the activities of daily life. The patient is currently alive 6 months after the 2nd operation without any sign of recurrence. ECMO is a useful technique for thoracic surgery after pneumonectomy.

Primary pulmonary leiomyosarcoma is a rare malignant tumor of the lungs. A 79-year-old woman showed a mass of 9 cm in diameter in a chest X-ray and computed tomography (CT) scan. A malignant tumor was suspected and left lower lobectomy was performed. From pathological findings, pulmonary leiomyosarcoma was diagnosed. The disease stage was pT2N0M0, p0d0e0pm0 (p0), pIB. From histopathological findings, the tumor appeared to be high grade, but no recurrences have occurred 2 years postoperatively and surgical treatment was considered effective.
