What is a neoplasm of fibroblasts?

Nodular fasciitis and fibromatosis
Granular cell tumor
Schwannoma
Neurofibromatosis type 1

The correct answer is: Nodular fasciitis and fibromatosis

Answer A neoplasm of fibroblasts is a type of tumor that develops from cells called fibroblasts, which are responsible for producing the structural framework of our tissues. This type of neoplasm is characterized by the abnormal growth and proliferation of fibroblasts, which can result in the formation of nodules or masses in different parts of the body. Nodular fasciitis and fibromatosis are both examples of neoplasms of fibroblasts, whereas the other options (B, C, and D) refer to neoplasms that involve different types of cells and have different characteristics. For example, granular cell tumors arise from nerve tissue, Schwannomas develop from Schwann cells, and neurofibromatosis type 1 is a genetic condition that affects nerve tissues. Therefore, these options are not considered neoplasms of fibroblasts.
