Tumors of the perionychium

Tumors of the nail bed are not as rare as we might imagine. Frequent marked delay in diagnosis or misdiagnosis not only contributes to these problems, but may even, on occasion, threaten a patient's life. Because the characteristics of these tumors in their earliest stages are subtle and their growth insidious they are easily missed by even careful observers. Special discussions on cysts, dermatofibroma, fibrous tissue lesions, glomus tumor, hemangioma, infection, neurofibroma, and sweat gland tumors are included.
