Follicular red dots: a normal trichoscopy feature in patients with pigmentary disorders? / Pontos vermelhos foliculares: um achado tricoscópico normal em pacientes com distúrbios da pigmentação?

Follicular red dots have been described as a trichoscopic feature of active discoid lupus erythematosus of the scalp and its presence associated with a better prognosis. We report five patients with pigmentary disorders in whom follicular red dots were detected during scalp examination. We suggest that this pattern is probably related to the rich vasculature that naturally envelops the normal hair follicle. The possible implications of such proposition in cases of discoid lupus erythematosus and other scalp disorders are also discussed.

Pontos vermelhos foliculares foram descritos como achado tricoscópico de lupus eritematoso discóide do couro cabeludo em atividade e a presença destes associado a melhor prognóstico. Relatamos cinco pacientes com distúrbios da pigmentação nos quais pontos vermelhos foliculares foram detectados ao exame do couro cabeludo. Sugerimos que este padrão está provavelmente relacionado à rica vascularização que naturalmente envolve o folículo piloso normal. As possíveis implicações desta suposição nos casos de lupus eritematoso discóide e outras doenças do couro cabeludo também são discutidas.

Standard guidelines of care: laser and IPL hair reduction.

Laser-assisted hair removal, Laser hair removal, Laser and light-assisted hair removal, Laser and light-assisted, long-term hair reduction, IPL photodepilation, LHE photodepilation; all these are acceptable synonyms. Laser (Ruby, Nd Yag, Alexandrite, Diode), intense pulse light, light and heat energy system are the different light-/Laser-based systems used for hair removal; each have its advantages and disadvantages. The word "LONG-TERM HAIR REDUCTION" should be used rather than permanent hair removal. Patient counseling is essential about the need for multiple sessions. PHYSICIANS' QUALIFICATIONS: Laser hair removal may be practiced by any dermatologist, who has received adequate background training during postgraduation or later at a centre that provides education and training in Lasers or in focused workshops providing such training. The dermatologist should have adequate knowledge of the machines, the parameters and aftercare. The physician may allow the actual procedure to be performed under his/her direct supervision by a trained nurse assistant/junior doctor. However, the final responsibility for the procedure would lie with the physician. FACILITY: The procedure may be performed in the physician's minor procedure room. Investigations to rule out any underlying cause for hair growth are important; concurrent drug therapy may be needed. Laser parameters vary with area, type of hair, and the machine used. Full knowledge about the machine and cooling system is important. Future maintenance treatments may be needed.
