androgenic alopecia as a physiologic process and benign prostatic hyperplasia (bph) as a pathologic process in the older population are androgen-dependent processes influenced by 5-alpha reductase enzyme which converts testosterone to dihydrotestosterone. this cross sectional study was done to evaluate the relationship between androgenic alopecia and bph. 150 men older than 50 years old, who pr...

Alopecia areata incognita, also known as diffuse alopecia areata, is a rare form of alopecia areata described predominantly in young women. In cases of alopecia areata incognita, the typical patchy distribution of hair loss in classical alopecia areata is absent, but abrupt and intense hair loss is characteristic. While the clinical picture presented by this disease closely resembles that of te...

we present a 21-years old woman with alopecia universalis, generalized vitiligo, and graves' disease. she had had thyroidectomy in early childhood and was receiving replacement therapy with levothyroxine. the patient was treated with systemic puva and glucocorticoid in combination with topical treatment for alopecia. after 6 months of treatment, alopecia was reversed but vitiligo was unchanged.

Prostaglandin F2α analogs, commonly prescribed for glaucoma treatment, have been shown to induce side effects such as cutaneous hypertrichosis and hyperpigmentation. Therefore, these medications have theoretic applications in the treatment of alopecia and disorders of hypopigmentation. We reviewed the literature to find original studies assessing the use of prostaglandin F2α analogs in these se...

BACKGROUND Alopecia can be a manifestation of mycosis fungoides (MF) and Sézary syndrome (SS), but the prevalence is unknown. OBJECTIVE We sought to describe the clinicopathologic presentation and molecular features of alopecia in patients with MF/SS. METHODS A retrospective chart review of a prospectively collected MF/SS database was used to identify patients with alopecia. The National Al...

Diffuse alopecia is mainly caused by telogen effluvium, diffuse androgenetic alopecia (female-pattern hair loss) and diffuse alopecia areata. Differential diagnosis between the three disorders may be difficult in several occasions. In this second part of our study, chronic telogen effluvium and diffuse alopecia areata are discussed in detail, including clinical, dermoscopic and histological asp...

Androgenetic alopecia is considered to be associated with coronary heart disease but the explanation of this association remains unknown. Hypertension is highly prevalent in patients with coronary heart disease. Essential hypertension is linked to hyperaldosteronism and spironolactone, an antihypertensive drug which is a mineralocorticoid receptor antagonist, has been used for a long time in th...

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...
