Insights

A Cocker Spaniel with a skin mass showed pyogranulomatous inflammation and Candida parapsilosis complex fungi. The fungal infection was likely secondary to a benign keratinizing lesion, highlighting a rare veterinary finding.

Area of Science:

  • Veterinary Cytology
  • Mycology
  • Dermatology

Background:

  • Candida parapsilosis complex is an emerging pathogen in human medicine.
  • Information on its presence and cytologic features in veterinary patients is limited.
  • Cutaneous masses in dogs can present with diverse cytologic findings.

Observation:

  • Fine-needle aspirates from a Cocker Spaniel's cutaneous mass revealed marked pyogranulomatous inflammation.
  • Fungal organisms were identified within the inflammatory exudate.
  • MALDI-ToF analysis confirmed the fungi as Candida parapsilosis complex.

Findings:

  • Histopathology of the excised mass diagnosed a benign keratinizing lesion.
  • The fungal infection was deemed secondary or incidental to the primary skin condition.
  • Cytologic features of Candida parapsilosis complex in a canine cutaneous mass were described.

Implications:

  • This case increases awareness of Candida parapsilosis complex in veterinary dermatology.
  • It highlights the importance of identifying fungal organisms in cytologic samples, even when secondary.
  • Further research is warranted on the significance of this fungus in animal health.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
