title: Neck sweat gland cancer hemorrhage. Case study.
abstract: BACKGROUND
  This paper reports a case of an 87-year-old female patient who was admitted for an emergency operation due to massive hemorrhage of an ulceration localized on a huge neck tumor. Post-interventional diagnosis indicated hidradenocarcinoma. Hidradenocarcinoma is a rare skin neoplasm. It can coincide with adenoma, may develop through its malignant transformation or develop as a malignant tumor from the beginning. It may be found in all dermal localizations. It may develop metastases or appear in the diffuse form.
  
  
  METHODS
  Surgical excision of the tumor was performed obtaining a surgical margin, completed with excision of local lymph nodes and multiple layer suturing. Due to lack of the patient's consent, she has not been qualified for adjuvant therapy.
  
  
  RESULTS
  Control examination 6 and 12 months later showed no signs of local recurrence or lymph node metastasis.
  
  
  CONCLUSIONS
  Surgical excision of apocrine hidradenocarcinoma with a surgical margin could present a good therapeutic effect in spite of lack of adjuvant therapy.
