Small cell eccrine carcinoma

Last edited: 4/15/2026

Overview

Small cell eccrine carcinoma is a rare variant of eccrine sweat gland carcinoma characterized by its aggressive behavior and neuroendocrine differentiation, often presenting as deeply invasive tumors with potential for metastasis 1.

Diagnosis

  • Histopathological examination essential for diagnosis, identifying small cell morphology 1.
  • Immunohistochemistry typically shows expression of neuroendocrine markers such as chromogranin A and synaptophysin 1.
  • Imaging studies (e.g., CT, MRI) useful for staging and assessing extent of disease 1.

    • Management

  • Surgical resection with wide margins is the primary treatment when feasible 1.
  • Adjuvant radiotherapy often recommended for residual disease or incomplete resection 1.
  • Chemotherapy regimens may include platinum-based agents (e.g., cisplatin) and etoposide, though specific dosing details are not provided in the abstract 1.
  • Supportive care measures tailored to manage symptoms and side effects 1.

    • Special Populations

  • No specific guidelines provided for management in pregnancy, pediatrics, elderly, or patients with comorbidities based on the given abstracts 1.

    • Key Recommendations

  • Perform histopathological examination and immunohistochemistry for definitive diagnosis (Evidence: Expert opinion 1).
  • Consider surgical resection with appropriate margins as the primary treatment approach when possible (Evidence: Expert opinion 1).
  • Utilize adjuvant radiotherapy for cases with incomplete resection or residual disease (Evidence: Expert opinion 1).
