A lipoma is a benign tumor of fat cells. It grows under the skin in the subcutaneous tissue which contains many fat cells. It is slow growing and may occur singly or in multiple numbers. Lipoma usually causes no symptoms. Most lipomas require no treatment. Surgical excision is done for large lipoma and for cosmetic purpose. Cure is possible by surgical excision on individual tumor. Neurofibroma is a tumor of nerve. It may be single or numerous. It is also treated by surgical excision. When it occurs in large numbers it is called neurofibromatosis. It is mostly genetic disorders. Neurofibromatosis is not curable as it is not possible to remove large number of tumors. Surgery is recommended to remove the tumors, but tmours keep on developing after removal. As there is a discrepancy in biopsy report, I suggest you for re-biopsy & histo-pathological examination in a different reputed pathological laboratory. Remember, lipoma is curable by surgical excision but neurofibromatosis is not curable. Thanks
