In a two-year carcinogenicity study with administration of high doses of the partial nicotinic agonist varenicline (recently approved for smoking cessation), mediastinal hibernomas occurred in three male rats. To investigate potential mechanisms for partial and full nicotinic agonists to contribute
In humans, hibernoma is a very rare, benign neoplasm of brown adipose tissue (BAT) that typically occurs at subcutaneous locations and is successfully treated by surgical excision. No single cause has been accepted to explain these very rare human tumors. In contrast, spontaneous hibernoma in rats
Benign symmetric lipomatosis (BSL), also known as Madelung's disease, is a rare condition and characterized by diffuse but painless growth of unencapsulated lipomas. A close correlation to alcohol and nicotine abuse, metabolic disturbances and malignant tumours have been observed. Surgical treatment
BACKGROUND
Therapeutic approach to incidentaloma, in spite of existing algorithms, is not always obvious due to diagnostic difficulties. The aim of the study was to assess the validity of the initial diagnoses of incidentaloma which determined the qualification for the operation.

Approximately one out of 500 chest radiographs shows the incidental finding of a solitary pulmonary nodule and almost one half of these pulmonary lesions are caused by a tumor. Unfortunately, only 2% to 5% of all lung tumors are of benign origin, e. g. lipoma, fibroma, hamartoma, and chondroma, and
Benign symmetrical lipomatosis (BSL), or Madelung's disease, is a rare disease characterized by the progressive growth of diffuse, painless, non-enveloped symmetric lipomas. The etiology of this disease remains unknown, although it was associated in the medical literature with alcohol and nicotine
