Y Hiss, R Shafir

The Journal of Dermatologic Surgery and Oncology

|December 1, 1978

Summary

This summary is machine-generated.

A pigmented lesion mimicking melanoma developed in keloidal scars after partial nevus removal. Complete nevus excision is advised to prevent future diagnostic uncertainty and potential melanoma misdiagnosis.

Area of Science:

Dermatology
Oncology
Pathology

Background:

Intradermal and compound nevi are common benign skin growths.
Partial excision of nevi can lead to scarring, including keloids.
Superficial spreading malignant melanoma is a type of skin cancer.

Observation:

A pigmented lesion resembling superficial spreading malignant melanoma was observed.
This lesion appeared within keloidal scarring.
The scarring resulted from prior partial excision of multiple nevi.

Findings:

The observed lesion mimicked malignant melanoma clinically.
The development occurred in the context of post-surgical scarring from nevus removal.
Histopathological evaluation is crucial for definitive diagnosis.

Implications:

Keloidal scarring after partial nevus excision can obscure or mimic melanoma.
Complete excision of nevi, when feasible, is recommended to avoid diagnostic ambiguity.
Early and accurate diagnosis of skin lesions is critical for effective melanoma treatment.
