Background and Objective: Non-scarring alopecia is a challenge in the diagnosis and treatment, rarely studied in Asian countries. The current study aimed at evaluating histopathological features including hair count of different subtypes of non-scarring alopecia in Iranian patients.Methods: The current study was conducted on 114 cases diagnosed with...
Alopecia can be either scarring or non-scarring. Non-scarring alopecias tend to have preserved follicular ostia, with no clinically visible inflammation in most presentations, although histologic inflammation may be present. The common types of non-scarring alopecias are androgenic alopecia, telogen effluvium, alopecia areata, trichotillomania and traction alopecia. Scarring alopecias, also kno...
Alopecia areata is an unpredictable, non-scarring hair loss condition. Patchy alopecia areata sparing gray hairs is rare. Here we present 4 cases with patchy non-scarring hair loss, which attacked pigmented hairs only and spared gray hairs. It should be differentiated from vitiligo, colocalization of vitiligo and alopecia areata, and depigmented hair regrowth after alopecia areata.
Hair loss may accompany several endocrine disorders, including hypopituitarism, hypothyreosis, hyperthyreosis, hypoparathyroidism, diabetes mellitus, growth hormone deficiency, hyperprolactinaemia, polycystic ovary syndrome, SAHA syndrome, congenital adrenal hyperplasia, Cushing syndrome, or virilising tumours. Most patients with endocrine disorders present with diffuse non-scarring alopecia, s...

Piccardi-Lassueur-Graham-Little syndrome is a rare entity characterized by progressive scarring alopecia of the scalp and keratotic papules on hairless skin, associated with non-scarring alopecia in the axilla and pubic area or lichen planus lesions. We describe the case of a 70-year-old woman who presented a Piccardi-Lasseur-Graham-Little syndrome, along with frontal fibrosing alopecia.
Alopecia in a linear pattern is very rare with only a few cases reported in the medical literature. We report a case of linear non scarring alopecia involving the scalp in a 17-year-old boy with a histological diagnosis of lupus panniculitis. We report this case because of its rarity and also the inclusion of this entity as one of the rare differential of non scarring alopecia.
UNLABELLED BackgroundAcquired alopecia of the lower legs may occur secondary to friction due to socks, footwear, or both on the lower extremities. There is scant literature that reports on this phenomenon.Methods and MaterialsWe describe 5 patients who presented with alopecia of their lower legs induced by socks, footwear, or both. METHODS AND MATERIALS We reviewed PubMed for the following te...
Temporal triangular alopecia, also referred as congenital triangular alopecia, is an uncommon dermatosis of unknown etiology. It is characterized by a non-scarring, circumscribed alopecia often located unilaterally in the frontotemporal region. It usually emerges at ages 2-9 years. Alopecia areata is the main differential diagnosis, especially in atypical cases. Dermoscopy is a noninvasive proc...
BACKGROUND Alopecia is one of the most important hair follicle (HF) disorders, which is divided into scarring (cicatricial) and nonscarring (noncicatricial) types. OBJECTIVE The aim of this study is to investigate the expression of stem cell (SC) markers such as cytokeratin (CK) 17 and CK19 in scarring and nonscarring alopecia. MATERIALS AND METHODS Thirty patients with scalp alopecia (15 w...
