Pulmonary sclerosing pneumocytoma-a case series.

Pulmonary sclerosing pneumocytoma (PSP) is a rare and interesting pulmonary tumour that presents a diagnostic challenge to the surgeon due to its bland symptomatology, indolent course, non-specific radiological features and ambiguous histopathological findings, which could lead to errors in management and prognostication. Herein, we present a series of 4 patients with PSP who were managed in our institution over a period of 8 years and briefly discuss relevant literature.

Aspergillus flavus costochondritis following coronary artery bypass grafting: a case report and a brief review of literature.

Bacterial sternal wound infections following cardiac surgery are not uncommon. However, sternal wound infection by a fungus is a rarity, and it warrants a correct diagnosis followed by specific treatment. We report a case of Aspergillus sternal wound infection with costochondritis following cardiac surgery, and briefly review the relevant literature.

Mediastinal teratoma presenting as a cervical tumor: images.

Benign extra-gonadal germ cell tumors, known as teratoma or dermoid cysts, are commonly found in the anterior mediastinum in association with the thymic gland. This association is due to their common site of embryological origins, from the third and the fourth pharyngeal pouches. Since it is not unusual to find normal thymic tissue in the neck, germ cell tumors arising from here will present as a cervical tumor. We submit the typical images of one such tumor in a young adult. Intraoperatively, the tumor was well encapsulated and was connected to the mediastinal thymus by a long pedicle of thymic tissue. It was not related to the thyroid gland unlike a primary cervical teratoma. We present these typical images of a mediastinal dermoid in this unusual cervical location. The differential diagnoses to be considered clinically are primary cervical teratomas, thyroid tumors, lymph nodal pathologies, and branchial cyst.
