Subcutaneous phycomycosis mimicking synovial sarcoma

A 6‐year‐old girl presented to the pediatric surgery department with swelling of the right hand of 4 months’ duration. According to the patient’s parents, it started as a small nodule over the dorsum of the right hand which gradually increased in size covering nearly the whole of the hand. There was no history of preceding trauma or insect bite. She had no constitutional symptoms; however, she had limitation of movement of the fingers of the affected hand. The surgeon made a clinical diagnosis of synovial sarcoma. A biopsy specimen from the border of the lesion was obtained for histologic examination. Microscopic examination of the histologic section was not suggestive of this condition. Hence, she was referred to a dermatologist for expert opinion.
