Abstract
Inflammation and local pressure are common causes of localized acquired hypertrichosis (LAH). The vast majority of cases of LAH in this category described in the literature occurred after the patient underwent surgery or injection or had to wear a plaster cast. Localized acquired hypertrichosis usually disappears over time once the causative agent has ceased. This case report presents the case of a man who acquired LAH of terminal hair through inflammation and local pressure while working in mining for over 20 years. The statistical analysis showed no statistical difference between hair thickness from both shoulders. The photos show the hair under a scanning electron microscope.
