Review
Actinic keratosis (AK) is a common precancerous condition found on chronically sun-damaged skin, particularly on the face, scalp, arms, and legs. Early and effective treatment of AKs is important to prevent progression to squamous cell carcinoma. Many topical treatments for AKs are often limited because of poor tolerability, prolonged treatment duration, and reduced adherence. Tirbanibulin 1% ointment, a new topical field therapy for AKs, reduces these issues. It requires a consecutive 5-day application period and is effective, demonstrating complete (100%) clearance of AK lesions in 49% of patients, partial (>75%) clearance in 72%, and a median reduction in lesion count of 87.5% while exhibiting a favorable safety profile, mild adverse events, improved tolerability, and long-term results.

Trichilemmal or "pilar" cysts are commonly found on the scalp and are derived from the outer root sheath of the hair follicle. Multiple trichilemmal cysts present in an autosomal dominant pattern of inheritance, yet the genetic mechanism has remained elusive. In this issue, Hörer et al. (2019) highlight predisposing variants in PLCD1 in such families and propose a monoallelic mutational mechanism that drives cyst formation.

AIM
To describe in detail the gross anatomy of the superficial temporal artery (STA), its course and branches, its relationships with the branches of the facial nerve, and certain anatomical and surgical landmarks to preserve these structures in daily neurosurgical practice, and to use the STA during revascularization surgery.
MATERIAL AND METHODS
This cadaveric study was conducted on 16 cadaver heads bilaterally, in which 32 silicon/latex-injected STAs were dissected using a microdissection technique in a neuroanatomy laboratory. The distances between the facial nerve, tragus, STA, superficial temporal vein (STV), and imaginary lines created between important anatomical landmarks were measured. The curvilinear lengths of STA and STV were also measured.
RESULTS
The average distances of the most posteriorly located branch of the facial nerve to the frontal region and the tragus at the midpoint of zygoma in the horizontal plane, at the superior border of the zygoma and at the level of the superior border of the parotid gland, were measured as 25.39, 29.84, and 15.56 mm, respectively. The average distance directly measured between the tragus and STA was 39.29 mm, and that between the tragus and STV was 20.26 mm. The average curvilinear lengths of the frontal and parietal branches of STA were 97.63 and 96.45 mm, respectively.
CONCLUSION
Understanding the clinical anatomy of the STA and its branches and its relationships with other structures is of critical importance for a successful and noncomplicated surgery. Our findings will be useful not only for surgical approaches such as pterional craniotomy and orbitozygomatic approaches but also for cerebral revascularization.

Review
Identifying the localization, distribution, and polarity of waveforms are the prime goals of clinical scalp EEG analysis. Appropriate choices of bipolar and referential montages are keys to emphasizing the diagnostic features of interest, and demand some understanding of the spatiotemporal physical behavior of the underlying neuronal generators. Several examples drawn from canonical epilepsy syndromes are used to illustrate this general message.

Review
Scalp is a unique location for pemphigus because of the abundance of desmogleins localized in hair follicles. Scalp involvement is observed in up to 60% of patients in the course of pemphigus. The lesions may occasionally lead to alopecia. Unforced removal of anagen hairs in a pull test is a sign of high disease activity. Direct immunofluorescence of plucked hair bulbs is considered a reliable diagnostic method in patients with pemphigus. Follicular acantholysis is a characteristic histopathological feature of pemphigus lesions localized on the scalp. Trichoscopy may serve as a supplementary method in the diagnosis of pemphigus. This review summarizes the most recent data concerning scalp involvement in pemphigus vulgaris and pemphigus foliaceus. A systematic literature search was conducted in three medical databases: PubMed, Embase, and Web of Science. The analysis included literature data about desmoglein distribution in hair follicles, as well as information about clinical manifestations, histopathology, immunopathology, and trichoscopy of scalp lesions in pemphigus and their response to treatment.
