Eccrine Porocarcinoma with Zosteriform Metastasis.

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Eccrine porocarcinoma is a rare adnexal carcinoma with high metastatic potential.
• Diagnosis is primarily histological, posing a challenge due to its rarity.

Observation:

• A case of a male patient with eccrine porocarcinoma presenting with extensive zosteriform skin metastasis and lymph node involvement is described.

Findings:

• The patient's extensive metastatic eccrine porocarcinoma was treated with chemotherapy and concomitant radiotherapy.
• Surgical resection with tumor-free margins and sentinel node biopsy are standard treatments, with chemotherapy and radiotherapy for metastatic disease.

Implications:

• This case contributes to understanding treatment approaches for rare metastatic eccrine porocarcinoma.
• Further research is needed to establish standardized treatment guidelines for this challenging malignancy.
