A rare skin tumor, papillary eccrine adenoma, was diagnosed in a patient presenting with a hand nodule. Histological examination revealed characteristic dilated ducts and papillary projections within the dermis.

Area of Science:

  • Dermatopathology
  • Surgical Pathology
  • Oncology

Background:

  • Skin tumors present a wide differential diagnosis.
  • Eccrine gland tumors are uncommon but important to recognize.

Purpose of the Study:

  • To report a case of papillary eccrine adenoma.
  • To describe the clinical and histological features of this rare skin neoplasm.

Main Methods:

  • Clinical presentation of a solitary nodule on the hand.
  • Histopathological examination of the excised nodule.
  • Microscopic analysis of dermal structures and cellular morphology.

Main Results:

  • Histology showed multiple dilated dermal ducts with branching tubules.

  • Luminal contents were eosinophilic and amorphous.
  • Papillary projections lined by cuboidal cells with peripheral myoepithelial cells were observed.

    • Conclusions:

    • The observed features are diagnostic of papillary eccrine adenoma.
    • This rare tumor requires careful histological evaluation for accurate diagnosis.
    • Understanding the morphology is key to differentiating it from other adnexal neoplasms.
