Raoultella ornithinolytica is an encapsulated, Gram-negative, nonmotile aerobic rob which was reclassified from Klebsiella genus belonging to the family of Enterobacteriaceae. It is a rare human infection and few cases have been reported in post thoracotomy patients. Here we present a case of a left lower lobectomy patient that was complicated by pleural effusion, high fever with positive sputum cultures of Raoultella ornithinolytica and positive pleural fluid cultures of Staphylococcus hominis. The disease is related with aquatic life poisoning. There are few cases reported and even fewer postoperatively. The infection is rare in humans therefore the bacteria is still underreported.

The familial occurrence of thymic pathology, even though rare, is widely reported in the literature and mainly concerns cases of familial autoimmune myasthenia gravis. Other less frequent cases of familial occurrence of thymoma, thymic carcinoid and thymic hyperplasia have been described. It seems that the familial occurrence is poorly recorded and thus its prevalence is underestimated. We report two families whose members presented different forms of thymic pathology and discuss the necessity of screening programs in family members of patients presenting a thymic lesion.

Breast reconstruction is a very popular surgical intervention performed either for cosmetic reasons or after oncological resections. Even though silicone is considered to be an inert material, there are side effects that have been reported, such as silicone lymphadenopathy. In the case reported herein, a silicone lymphadenopathy of the internal mammary and the anterior mediastinal lymph nodes were revealed after a thymectomy for autoimmune myasthenia gravis. Silicone lymphadenopathy should always be part of the differential diagnosis of enlarged lymph nodes, in patients with previous cosmetic or oncoplastic surgery with the use of silicone gel breast implants. Special attention should be paid in case of previous breast cancer in order to rule out metastasis.
