AbstractHistopathological features are important for the practicing hair transplant surgeon to ensure proper case selection, diagnosis, choice of proper treatment, and successful outcome. While the primary focus of the hair transplant surgeon is androgenetic alopecia (AGA), it is important to be aware of other conditions that can mimic AGA, whose treatment may be different. This article outlines some of these conditions such as scarring alopecias, alopecia areata, etc., and how to distinguish them. Proper identification will ensure proper treatment and avoid potential missteps in management.

<b><i>Introduction:</i></b> All types of lupus erythematosus (LE) may cause hair loss. Nonscarring alopecia was correlated with systemic LE, based on its high specificity. Discoid LE can also appear as nonscarring patches in early stages. Patchy alopecia LE-specific may also mimic alopecia areata (AA) – which can co-occur with LE. The distinction is fundamental to early diagnosis and effective treatment. This study aims to analyze clinical, epidemiological, trichoscopic, and histopathological features of patients with patchy LE-specific alopecia, nonscarring type, mimicking AA. <b><i>Methods:</i></b> This is a multicentric retrospective study. We reviewed the medical records of patients with a confirmed diagnosis of LE mimicking AA. <b><i>Results:</i></b> Ten patients were included (90% female) with a mean age of 45.9 years. Clinically, 60% showed erythema and 70% presented incomplete hair loss. The most common trichoscopic findings were interfollicular arborizing vessels (90%) and scattered brown discoloration (80%). On histopathology, perivascular inflammation (85.7%), peribulbar lymphocytes (85.7%), and dermal pigment incontinence (71.4%) were present in most cases. <b><i>Discussion/Conclusion:</i></b> Trichoscopy was found as an essential first step for the patchy alopecia diagnosis, enabling to differentiate LE from AA. Putting it mildly, trichoscopy raises the suspicion that leads to a biopsy, increasing the diagnostic accuracy with better outcome for patients.

Broad Overview

A basic knowledge of the hair growth cycle is needed to evaluate disorders of hair growth. This chapter presents a broad overview of the physiology and evaluation of hair growth, as well as discussions of specific types of alopecia. The epidemiology, pathogenesis, diagnosis, and treatment of androgenetic alopecia, the most common type of nonscarring hair loss, are covered. Diffuse hair shedding is generalized hair loss over the entire scalp. Diagnosis and treatment of telogen effluvium, anagen arrest (anagen effluvium), and other causes of diffuse hair shedding are covered in detail. Alopecia areata, typically characterized by patchy hair loss; cicatricial alopecia, which results from permanent scarring of the hair follicles; and miscellaneous causes of hair loss are also discussed. Tables list the causes of diffuse and cicatricial alopecia, telogen effluvium, and miscellaneous chemicals and categories of drugs that can cause alopecia, as well as miscellaneous causes of hair loss. Included is an algorithm outlining the approach to diagnosing nonscarring alopecia, as well as a variety of clinical photographs. This review contains 9 highly rendered figures, 6 tables, and 42 references.

Androgenetic Alopecia

Diffuse alopecia is mainly caused by telogen effluvium, diffuse androgenetic alopecia (femalepattern 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 aspects. A flowchart presents a practical and objective differential diagnostic approach to diffuse alopecia.
