AI Article Synopsis
- - A 43-year-old man showed signs of patchy hair loss and re-growth patterns typical of trichotillomania, prompting a biopsy for diagnosis.
- - The biopsy results showed abnormalities associated with trichotillomania, including a unique feature where hair shafts appeared split and contained certain materials, resembling a "hamburger in a bun."
- - This "hamburger bun sign" is a new observation that could help in identifying traumatic injuries in biopsy examinations related to trichotillomania.
Article Abstract
Background: A 43-year-old male presented with the clinical findings of patchy alopecia that contained persistent hair and re-growth of hairs of various lengths, consistent with trichotillomania. A biopsy was performed to confirm the diagnosis..
Results: Histologic evaluation revealed findings consistent with trichotillomania, including trichomalacia. Several hair shafts also showed a vertically oriented split, which contained proteinaceous material and erythrocytes. Morphologically, these were reminiscent of a hamburger within a bun.
Conclusions: The unusual finding reported in this case has not been previously reported. The "hamburger bun sign" provides an additional clue to traumatic injury in the evaluation of biopsies for trichotillomania.

This literature review aims to comprehensively evaluate the clinical and dermoscopic presentations of common pediatric diseases among children with skin of color (SoC) while also addressing potential variations based on racial backgrounds. This review encompasses various conditions, such as nevi subtypes, viral infections, infestations, and inflammatory dermatoses, as well as hair diseases and abnormal vascular formations, occurring in pediatric populations. Overall, we identified 7 studies on nevi subtypes, 24 studies on skin infections, 6 on inflammatory dermatoses, 10 on hair diseases and disorders, and 14 on miscellaneous disorders that also satisfied our SoC- and race-specific criteria.

Article Synopsis
- - Trichodynia is a painful sensation in the scalp often linked to various types of hair loss, including androgenic alopecia and telogen effluvium, and is more common in women with psychiatric issues like anxiety and depression.
- - The exact cause of trichodynia is not well understood, but factors like substance P, inflammation, and mental health conditions may play a role in its development.
- - Currently, there's no specific treatment for trichodynia, but options like botulinum toxin A, antidepressants, and corticosteroids can be explored, prompting a call for more research into effective therapies.

Article Synopsis
- A study analyzed PTSD rates among 209 adults with trichotillomania by using self-report surveys conducted between April and May 2023.
- Results showed that 19.1% of participants had PTSD, with a higher likelihood of being male and having issues with alcohol use and impulsive behaviors like gambling and stealing.
- There was no connection found between PTSD and the severity of trichotillomania symptoms, suggesting that managing trauma could potentially help with related disorders.
Habit-reversal training: a psychotherapeutic approach in treating body-focused repetitive behaviour disorders.
Clin Exp Dermatol
November 2023
Institute of Psychology, Mykoles Romeris University, Vilnius, Lithuania.
Body-focused repetitive behaviours (BFRBs) are recurrent, compulsive, destructive behaviours directed towards the body. Although studies have demonstrated a 12-14% prevalence rate, researchers found that dermatologists and psychiatrists show a lack of knowledge regarding psychodermatology resources and information about BFRB disorders (BFRBDs) such as trichotillomania (TTM). There is limited research about treatments including ones investigating the clinical applications of various self-help training such as decoupling (DC) and DC in sensu (DC-is) as well as about habit-reversal training (HRT).
