Cutan metastases of neuroendocrine cancer (NET)

Neuroendocrine cancers of the lungs are rare, which can give also cutaneous metastases. These tumors are often delayed accidental. Treatment is different from this in normal lung cancer.

case report in the 83-year-old patient, many bloody repeated indolent masses of facial skin and auricula on the left has been found for years. The patient was free of complaints. Histological moderately differentiated squamous cell carcinoma (G2) of the auricula and a kutaneous metastasis of the neuroendocrine not small cell carcinoma frontal on the left could be detected. In the course of the search for the primary tumor, oesophagogastroscopy, colonscopy and radiographic techniques were carried aut , which showed the detection of the tumor at inferior lobe of left lung. A cutaneous metastasis from bronchial cancer was discussed.

Discussion NET occurs in 1-2/100000 of population. Endocrine active tumors can be detected at an early stage through targeted blood testing. Inactive tumors are often delayed discovered through their size or as a result of metastases. Radiographic techniques can detect the localization of the primary tumor. Treatment options depend on the stage, the localization of the primary tumor and the stage of metastases development.

Konklusion although 75 % of all these tumors are localized in the gastrointestinal system, they can also occur in the bronchial system. Cutan metastases in bronchial cancer should be viewed differently diagnosed if an unclear mass exists . Because NET in the bronchial system are often thought to be normal lung cancer, treatment is sometimes inadequate
