Unique Skin Metastasis from Recurrent Cancer. Case Report

Area of Science:

• Oncology
• Dermatology
• Pathology

Background:

• Cutaneous metastasis involves malignant cells spreading to the skin from a primary tumor.
• It can occur via direct invasion or hematogenous spread from internal malignancies.
• This case highlights late-onset skin metastasis from breast cancer.

Observation:

• A 75-year-old female presented with isolated papular and nodular skin lesions on the left abdomen.
• No other clinical symptoms or systemic signs of malignancy were present.
• Histopathology confirmed dermal infiltration by tumor cells.

Findings:

• Skin metastasis was the sole presenting clinical sign of recurrent breast cancer.
• Diagnosis was established 8 years post-initial treatment.
• Chemotherapy resulted in complete remission of skin lesions.

Implications:

• Cutaneous metastasis can be an isolated indicator of recurrent internal malignancy.
• Dermatologists play a crucial role in the early diagnosis of metastatic disease.
• Prompt diagnosis and treatment can lead to favorable outcomes.
