• 

  This photograph, taken at autopsy, demonstrates the distribution of neurofibromas on the skin of this patient.

• 

  This is another view taken at autopsy demonstrating the neurofibromas. Some lesions can be seen as subcutaneous swellings (arrow) and others form pedunculated masses. Most are hyperpigmented.

• 

  This is a closer view of neurofibromas on the skin.

• 

  This is a low-power photomicrograph of a subcutaneous neurofibroma (1). Note the increased pigmentation in the skin (2).

• 

  This is a higher-power photomicrograph of the neurofibroma (1) with the overlying skin (2).

• 

  This is a higher-power photomicrograph of the neurofibroma demonstrating the loose pattern of elongated cells making up the tumor mass.

• 

  This higher-power photomicrograph of the neurofibroma shows more clearly the elongated cells (primarily Schwann cells) that make up this tumor.

• 

  This is a high-power photomicrograph of the cells in the neurofibroma.
