Background:
Blastomycosis is rare in India. Clinically, cutaneous blastomycosis may be mistaken for keratoacanthoma, squamous cell carcinoma, tuberculosis, tertiary syphilis, leprosy or pyoderma.
Case:
A 19-year-old male presented with a soft, fluctuant swelling at the medial canthus of the eye. Fine needle aspiration biopsy (FNAB) showed many single, spherical structures with thick walls. They had basophilic protoplasm and six nuclei in the center. A few of them showed budding with a broad base.
Conclusion:
The cytomorphology of Blastomyces dermatitidis is characteristic, and the organism can be differentiated from other yeast forms. The disease is sensitive to antifungal imidazole derivatives and can be cured.
