  Abstract 


Localized hypertrichosis is a rare entity characterized by circumscribed patches of terminal hair. It may be associated with many underlying systemic abnormalities. In our case, a 5-year-old girl presented with complaints of multiple patches of hypertrichosis without any systemic abnormality since the last 4 years. We are reporting this case due to the rarity of hypertrichosis at abnormal sites.

Keywords: Hypertrichosis cubiti, hypertrichosis, localized hypertrichosis

  Introduction Top


Hypertrichosis is described as growth of an excessive amount of hair on any area of the body and above the normal for the age, sex, and race of an individual. It can be classified into generalized and localized type.[1] We report a 5-year-old girl with multiple patches of localized hypertrichosis without any pigmentary and systemic abnormality.


  Case Report Top


A 5-year-old girl came to us with multiple patches of localized hair over body. Dermatology consultation was taken due to cosmetic reasons. There was no hair growth at birth, but after a period of 6 months, a patch of hair first developed over back of the right thigh [Figure 1]. Steadily, the hairs increased in size to about 2–3 cm in duration of 2 years. Similarly, hair also developed over the body symmetrically over the arms, face, and on the hip region.

Dermatological examination revealed multiple ill-defined patches of hair over the right thigh and bilaterally symmetrical over the elbows, hip, and face [Figure 2], [Figure 3], [Figure 4]. The hairs were terminal, pigmented of size variable from 2 cm over the face to about 4 cm over the thigh and elbows. The skin over the patch was normal without any pigment abnormality.

On investigating the patient, thyroid-stimulating hormone, cortisol, hormonal profile, routine counts, and ultrasonography abdomen came out to be normal.

As the patient had cosmetic concern predominantly, we counseled the patient to use mechanical removal of hair by scissors and using chemical anti-epilatory creams and advised the patient to go for laser removal after puberty.


  Discussion Top


Primary hypertrichosis has been defined based on the age of onset as congenital or acquired and on the extent of distribution as localized or generalized.[1] Localized hypertrichosis is a rare entity characterized by the presence of hair in an asymmetrical or bilaterally symmetrical similar fashion. Localized hypertrichosis may be found as an isolated clinical lesion or in association with congenital melanocytic nevi, congenital Becker nevi, nevoid hypertrichosis, nevus pilosus, smooth muscle hamartomas, plexiform neurofibromas, and linear epidermal nevi.[2],[3],[4] It may present with an underlying spina bifida occulta, diastematomyelia, or kyphoscoliosis.[5]

There are multiple case reports, of which occurring at special anatomic sites such as hypertrichosis cubiti, hairy palms and soles, hairy pinna, anterior and posterior cervical hypertrichosis, and hypertrichosis of nasal tip. In most of the cases, hypertrichosis is of idiopathic type but in some cases, autosomal dominant and recessive forms had also been reported.[6],[7]

In this patient, hypertrichosis was not present in any of these patterns. The patient had hypertrichosis cubiti with hypertrichosis involving bilaterally symmetrical over face, hip and asymmetrically over right thigh. Due to rarity of this presentation, we are reporting this case.

Treatment generally involves various measures such as bleaching, trimming, waxing, physical and chemical depilatories, electrolysis, intense pulsed light therapy, and laser hair removal.
