Intraoral melanoacanthoma.

J M Wright, W H Binnie, D L Byrd

Journal of Periodontology

|February 1, 1983

Summary

This summary is machine-generated.

Melanoacanthoma, a benign oral tumor, presents as pigmented lesions on the buccal mucosa, often in Black females. Rapid growth can mimic melanoma, necessitating a biopsy for diagnosis.

Area of Science:

Oral pathology
Dermatology
Oncology

Background:

Melanoacanthoma is a benign mixed tumor characterized by keratinocytes and pigment-laden dendritic melanocytes.
Intraoral melanoacanthomas typically appear as pigmented lesions on the buccal mucosa.

Observation:

The presented cases involve melanoacanthoma occurring on oral mucous membranes.
These tumors have been predominantly reported in young to middle-aged Black females.

Findings:

Melanoacanthomas can exhibit rapid growth, potentially mimicking the radial growth phase of intraoral melanoma.
Clinical features of melanoacanthoma are not distinctive, making differentiation from other lesions challenging.

Implications:

Biopsy is essential for the accurate diagnosis of intraoral melanoacanthoma.

Understanding the clinical presentation and potential for rapid growth is crucial for appropriate patient management.
