“…Barbers interdigital pilonidal sinuses have been reported sporadically (Allington, 1942;Patey & Scarff, 1946;King, 1949;Joseph & Gifford, 1954), and also similar lesions in dog groomers (Price & Popkin, 1976), milkers (Meneghini & Gianotti,t964) and sheep shearers (Matheson, 1951). I can find no trace of reports of hair causing similar lesions on the breasts.…”
