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.

Hair Transplant

Androgenetic alopecia is a common condition, accounting for about 95% of all male hair loss. Standard therapeutic solutions recommend the use of minoxidil, finasteride, spironolactone, nutritional supplementation, phototherapy and hair transplant surgery. An increasingly popular alternative method that has been used in the case report is platelet rich plasma (PRP) mesotherapy characterized by autologous character, minimal invasiveness and no serious side effects. A series of 3 treatments was performed at 3-week intervals. The effects of using medical photographic documentation after completing a series of treatments.

Scalp Biopsy

Background: We report on a first case of lichen planopilaris (LPP) mimicking androgenetic alopecia (AGA) in an individual who has been break-dancing on his head for many years. LPP is an autoimmune inflammatory scalp condition that when left untreated can result in scarring and irreversible hair loss. The etiology of LPP is unknown. Different treatment modalities are used for LPP and AGA. Objective: To increase the awareness of physicians to the possibility of scarring hair loss (LPP) presenting like AGA. Results: Scalp examination showed scarring patches of hair loss. A scalp biopsy confirmed the diagnosis of LPP. Conclusion: Chronic scalp trauma due to break dancing may be a trigger for LPP. A meticulous scalp examination should be performed before making a diagnosis of nonscarring conditions of hair loss such as AGA. Early recognition of LPP and appropriate treatment are important before scarring and irreversible hair loss ensue.

Pattern Distribution

Fibrosing alopecia in a pattern distribution is a recently recognized type of scarring alopecia, with hair loss in androgens- dependent area. Loss of follicular openings, perifollicular erythema, perifollicular hyperkeratosis and anisotriquia are the trichoscopic clues and follicular lichenoid inflammatory infiltrate the important finding in histopathology. It shares features of androgenetic alopecia and lichen planopilaris. Dermatologists should be familiarized with this entity in order to optimize the diagnosis and provide early treatment to prevent irreversible follicular damage.

AbstractPreoperative diagnostic confidence and donor site assessment are important for all hair transplant surgery patients. While the majority of patients seek hair transplantation for male or female pattern hair loss (androgenetic alopecia [AGA]), there are mimickers that must be differentiated from patterned hair loss, as they alter the candidacy of the patient for transplantation. They are termed mimickers as they also can present with patterned hair loss. The use of trichoscopy has become increasingly popular for such use. Patterned hair loss mimickers, which include the underappreciated alopecia areata incognita (AAI) and fibrosing alopecia in patterned distribution (FAPD), can be identified clinically with key trichoscopic findings such as yellow dots and peripilar casts, respectively, that correlate with their histologic diagnosis. Donor hair density and putative hair pathology of the safe donor area can also by assessed via trichoscopy. This article discusses the use of trichoscopy, particularly for diagnosing mimickers of patterned hair loss as well as preoperative donor site assessment.

Histopathological Findings

It has been shown in previous studies that the toxin T-514 isolated from K. humboldtiana induces severe damage to the lung in treated rodents. Histopathological findings include edema, and alveolar hemorrage. However, the ultraestructure of the lesion has not been investigated. In this study we used two species of rodents: Hamster and guinea pig, and a primate: Macaca fascicularis. Animals received different single dosis of the toxin via intraperitoneal. Control animals received only the vehicle (propylen glycol). Inmediately after spontaneous death, lung samples were fixed in Karnovsky-Ito fixative, post fixed in osmium tetroxide and embedded in epon. Thin sections were prepared with an Ultratome V LKB, stained with uranly acetate and lead citrate, and studied in an electron microscope Zeiss-EM109.
