In veterinary dermatopathology skin biopsy is the essential technique to be able to perform the differential or definitive diagnosis of some diseases.

Skin biopsy

Skin biopsy is a technique which is generally indicated for diagnosing:

  • Neoplastic lesions
  • Persistent ulcers, gall bladders
  • Uncommon, rare or serious lesions
  • Diseases:
    • that do not respond adequately to treatment
    • that require long or dangerous treatment
    • in which diagnosis can only be performed through histopathology

Important: where biopsies are sent from the same animal, but from different pathologies, each of the samples shall be considered an independent biopsy.

Cutaneous cytology and aspirated cytology

  • Cutaneous surface cytology: this allows the diagnosis of some autoimmune diseases, and the presence of bacterial infections and/or infections by Malassezia spp, among others, to be directed.
  • Cytologies of aspirated nodules: these allow information about the origin of the mass, and in certain cases a first prognosis, to be obtained.

Special staining

  • LEISHMANIA IIP: special staining which allows Leishmania amastigotes to be detected.
  • PAS: special staining to diagnose fungal dermatosis.
  • GRAM and Z-N (Ziehl-Neelsen): special staining techniques to detect the presence of bacterial agents and micro-bacteria.
  • IIP for diagnosing neoplasias: Ki 67, c-kit, CD3, CD20.
  • Other staining techniques: check with our laboratory about availability.
