Journal of the American Academy of Dermatology

|June 1, 1983

Summary

This summary is machine-generated.

Multiple large cell acanthomas, a benign skin condition, present similarly to solitary cases. This finding expands the differential diagnosis for keratoses on sun-exposed skin.

Background:

Large cell acanthoma is a benign keratosis.
It typically presents as a hyperkeratotic, demarcated patch on sun-exposed skin.
Clinically, it is often misdiagnosed as seborrheic keratosis or solar keratosis.

Observation:

This report details the first two cases of multiple large cell acanthomas.
Clinical and histological features of multiple lesions were compared to a control group of solitary lesions.
The study observed identical clinical and histological characteristics between solitary and multiple forms.

Findings:

Multiple large cell acanthomas share identical clinical and histological features with solitary lesions.
The occurrence of multiple lesions does not alter the benign nature of large cell acanthoma.

This study expands the understanding of the presentation spectrum for this condition.

Implications:

Large cell acanthoma should be included in the differential diagnosis for both solitary and multiple keratoses.
Accurate diagnosis is crucial to avoid unnecessary treatments for benign lesions.
Awareness of multiple presentations aids clinicians in patient evaluation and management.
