Summary
This case report details a rare perianal hidradenocarcinoma, a malignant eccrine gland tumor. Early detection of inguinal metastases is crucial for suspecting anal canal tumors.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Eccrine glands are present throughout the skin, with higher concentrations on the hands and feet.
- Nodular hidradenocarcinoma (NH) is an uncommon, aggressive malignancy originating from eccrine glands.
- This study focuses on a rare instance of perianal hidradenocarcinoma.
Observation:
- A 75-year-old female patient with pre-existing diabetes, hypertension, and hypothyroidism presented with a small perianal tumor.
- Initial biopsy suggested perianal hidradenoma, but definitive pathology revealed malignant eccrine acrospiroma.
- Computed tomography indicated adenopathies in the inguinal and right iliac regions.
Findings:
- The definitive diagnosis was malignant eccrine acrospiroma of the perianal region.
- The patient underwent tumor resection and adjuvant chemotherapy.
- The patient unfortunately passed away one month post-treatment.
Implications:
- Metastases in the inguinal region as an initial symptom should raise suspicion for anal canal tumors.
- Highlights the importance of thorough evaluation for rare perianal malignancies.
- Emphasizes the aggressive nature and poor prognosis of advanced nodular hidradenocarcinoma.
