“…7 Our study shows an increase in M. lentiflavum identification in recent years, being the most common mycobacteria isolated (48%) in the last 5 years. Most published cases of M. lentiflavum lymphadenitis have been described in italy, 15,17,19 australia 23,25 and Spain, 16,18,20,21 whereas in other countries, such as the netherlands or israel, this mycobacteria is rarely isolated. 25 therefore, the change that we are describing here may also be taking place in other areas of the world.…”
