Soft Tissue Infection Caused by Rapid Growing Mycobacterium following Medical Procedures: Two Case Reports and Literature Review

Non-tubecrulosis mycobacterium infections were increasingly reported either pulmonary or extrapulmonary in the past decades. In Taiwan, we noticed several reports about the soft tissue infections caused by rapid growing mycobacterium such as Mycobacterium abscessus, Mycobacterium chelonae, on newspaper, magazines, or the multimedia. Most of them occurred after a plastic surgery, and medical or non-medical procedures. Here, we reported two cases of these infections following medical procedures. We also discussed common features and the clinical course of the disease, the characteristics of the infected site, and the treatment strategy. The literatures were also reviewed, and the necessity of the treatment guidelines was discussed.

Borderline mucinous cystic ovarian tumor with mural nodules [carcinosarcoma]

Carcinosarcoma mural nodules arising form a mucinous ovarian neoplasm is very rare and only two published cases have been reported. We report a case of a 29-year-old female patient who suffered from severe lower abdominal pain unrelated to menstruation for 1 year. She came to our [Shin-Kong Hospital] gynecology outpatient department in February 2010. The CT scan revealed a large cystic tumor, measuring approximately 36 cm in greatest dimension and at least 2 solid foci were noted. The patient underwent left salpingo-oophorectomy. A carcinosarcoma mural nodule arising within a mucinous ovarian neoplasm was diagnosed. The patient was treated by further chemotherapy and was free of the disease at time of publication. We reviewed the published studies, and in particular looked at the histology and immunohistochemistry of tumors, in which sarcomatoid carcinoma and carcinosarcomalike nodules were diagnosed. We also discussed the differential diagnosis of the mural nodule in a mucinous cystic neoplasm
