[Differential diagnosis of non-healing ‘fungal’patches in horses].

The study discusses how skin diseases in horses, specifically Dermatophytosis, if left untreated, are suspected to develop into sarcoids. The study also compares the clinical symptoms and therapeutic interventions for both affections and offers a review of the differential diagnoses.

Overview of Dermatophytosis and Sarcoids

• The study highlights Dermatophytosis as the most common skin disease in horses. Dermatophytosis, commonly referred to as ‘ringworm’, is a type of fungal infection that affects the skin, hair, and nails of the horse.
• The researchers suggest that Mycotic-like lesions, which are persistent and do not heal, could potentially be sarcoids. Sarcoids are a type of skin tumour that is commonly found in horses.

Clinical Symptoms and Therapeutic Interventions

• The study discusses the clinical symptoms of both affections. Dermatophytosis in horses may result in patches of hair loss, itchy and scaly skin, while sarcoids could cause wart-like, firm to the touch, and potentially non-healing skin lesions.
• In terms of therapeutic interventions, the researchers explore treatments suitable for both affections. Typical treatments for Dermatophytosis may include antifungal medications and maintaining a clean environment to prevent the spread of the infection. On the other hand, treatment for sarcoids could range from surgical removal, cryotherapy, to the application of anticancer drugs, depending on the severity and location of the tumour.

Differential Diagnoses

• Lastly, the study provides a short review of the differential diagnoses for Mycotic-like lesions that do not heal. The main goal of a differential diagnosis is to identify other potential diseases or conditions that could cause similar symptoms, hence ensuring the horse receives appropriate treatment.

In conclusion, the researchers emphasize the importance of accurately diagnosing non-healing ‘fungal’ patches in horses to ensure the correct treatment is provided, preventing the development of more serious conditions such as sarcoids.
