A case of pulmonary primary MALT lymphoma with distinctive bronchoscopic findings.

Mucosa-associated lymphoid tissue (MALT) is a low-grade lymphoma, but cases in which it has transformed into a high-grade lymphoma have been reported, necessitating an accurate diagnosis. The patient was a 79-year-old nonsmoking Japanese female with history of ocular sarcoidosis. A computed tomography scan of her chest revealed a 35-mm nodule in the left S1 + 2, contiguous with the lymph nodes.

Adenocarcinoma with mediastinal lymph node involvement developed from a pure ground grass nodule during 14 years.

A 69-year-old female Japanese patient presented with an abnormal shadow on chest computed tomography (CT). She had received a mastectomy 14 years prior. Under the diagnosis of primary lung cancer, left upper lobectomy was conducted.

Differential diagnoses of calcified nodules in pulmonary amyloidosis: A case report.

Pulmonary amyloidosis should be included in the differential diagnosis of calcified lung nodules, and more careful preparation for bleeding should be taken when performing bronchoscopy. While management does not require aggressive treatment, follow-up is necessary to monitor for multiple myeloma and malignant lymphoma.

Ovarian serous carcinoma in which mediastinal recurrence of the cancer was resected 16 years after surgery: A case report.

We report a rare case of ovarian carcinoma in which a mediastinal recurrence was resected 16 years after the initial operation. A 72-year-old woman underwent hysterectomy with adnexectomy for stage IIIC ovarian serous carcinoma after neoadjuvant chemotherapy. Six courses of adjuvant chemotherapy were administered.
