Trichothiodystrophy without Associated Neuroectodermal Features in Two Siblings.

Trichothiodystrophy (TTD) is characterized by the common feature of sulfur-deficient brittle hair associated with a constellation of neuroectodermal symptoms. There is a wide phenotypic variation in the severity; ranging from isolated hair defect to multiple neuroectodermal symptoms such as photosensitivity, ichthyosis, intellectual impairment, decreased fertility, and short stature. This case report describes TTD in two sisters with only hair fragility and no other associated feature.

NonScarring Diffuse Hair Loss in Women: a Clinico-Etiological Study from tertiary care center in North-West India.

Background: Diffuse hair loss (DHL) is a common problem in adult women and has a major impact on quality of life. Ascertaining the etiological diagnosis is a challenging task in such patients. Satisfactory treatment can only be instituted after ascertaining the cause of hair loss.

Extensive Donor Site Keloids in Follicular Unit Extraction Hair Transplantation.

Hair transplantation, a generally regarded as a safe surgical modality for the treatment of androgenetic alopecia, is not without its potential risks and complications. A case of an extensive keloid formation at donor site following follicular unit extraction is discussed. Hair transplant surgeons should be aware of this significant potential complication, especially in patients having previous keloidal tendencies to avoid such disastrous outcomes.

An innocent giant.

A cutaneous horn (cornu cutaneum) is a protrusion from the skin composed of a cornified material. It may be associated with a benign, premalignant, or malignant lesion at the base, masking numerous dermatoses. In a 24-year-old female, a giant cutaneous horn arising from a seborrheic keratosis located on the leg is presented.
