Low grade lesions: Carcinoid tumors are neuroendocrine tumors found in many organs of the body. Commonly they are found in the GI tract but can appear in the lung or even pancreas (Steve Jobs). The tumors are derived from endocrine cells producing hormone-like substances and resemble neurons secreting neurotransmitters. There are two types of lung carcinoid tumors: typical and atypical. In lung, typical carcinoids account for about 9 out of 10 lung carcinoids. They grow slowly and rarely spread beyond the lungs. Atypical carcinoids are much rarer. They grow somewhat faster and have a greater chance for metastasis..
