Pseudoatrophic macules associated with neurofibromatosis-1

Area of Science:

• Dermatology
• Clinical Genetics
• Oncology

Background:

• Neurofibromatosis type 1 (NF1) is a genetic disorder characterized by the development of tumors along nerves.
• Cutaneous neurofibromas are common in NF1, but specific clinical presentations can be rare.
• Understanding diverse manifestations is crucial for accurate diagnosis and management.

Observation:

• A 14-year-old male patient with a confirmed diagnosis of NF1 presented with skin lesions.
• The lesions were described as two ill-demarcated, grayish-white, and atrophic patches located on his left back.
• Histopathological examination confirmed the diagnosis of neurofibroma.

Findings:

• The observed clinical presentation of neurofibroma, specifically ill-demarcated, atrophic patches, is infrequently documented in NF1 patients.
• This case adds to the spectrum of cutaneous manifestations associated with neurofibromatosis type 1.
• Histopathology confirmed the nature of the skin lesions as neurofibromas.

Implications:

• This case underscores the importance of recognizing rare clinical presentations of neurofibromas in NF1.
• It may prompt further investigation into the diverse histopathological and clinical variations of neurofibromas.
• Enhanced awareness of such presentations can aid clinicians in diagnosing and managing NF1 patients effectively.
