“…It has to be emphasized that exclamation mark hairs may be present in every type of hair loss associated with development of Pohl-Pinkus constrictions (20), such as chemotherapy-induced alopecia (23), severe recurrent bleeding, or periodical malnutrition (20). We have not observed exclamation mark hairs in tinea capitis.…”

Differential diagnosis of trichotillomania is often difficult in clinical practice. Trichoscopy (hair and scalp dermoscopy) effectively supports differential diagnosis of various hair and scalp diseases. The aim of this study was to assess the usefulness of trichoscopy in diagnosing trichotillomania. The study included 370 patients (44 with trichotillomania, 314 with alopecia areata and 12 with tinea capitis). Statistical analysis revealed that the main and most characteristic trichoscopic findings of trichotillomania are: irregularly broken hairs (44/44; 100% of patients), v-sign (24/44; 57%), flame hairs (11/44; 25%), hair powder (7/44; 16%) and coiled hairs (17/44; 39%). Flame hairs, v-sign, tulip hairs, and hair powder were newly identified in this study. In conclusion, we describe here specific trichoscopy features, which may be applied in quick, non-invasive, in-office differential diagnosis of trichotillomania.

“…The Z hair is a zigzag-shaped hair with sharp bends at multiple points of the hair shaft as a result of focal weakening. Circle hair is a short, vellus hair that is thinned [10, 11]. The scalp biopsy showed basal-cell vacuolization of the follicular epithelium with lymphocytic exocytosis, a typical lichenoid reaction seen in GVHD.…”

“…The facial skin presents a remarkably elevated concentration of follicles in the postcranial anatomy, especially across the nose [25,26,27]. In living subjects, only 2-3mm of the vellus hair is exposed on the skin surface [28]. Following shrinkage, this hair becomes more obvious if not removed.…”

Recently identified features that help to distinguish ceremonial tsantsa from commercial shrunken heads

Highlights 65 shrunken human heads were examined using IRR, CT and microscopic hair analysis. Ten new characteristics for distinguishing ceremonial and commercials heads were identified. Commercial heads may be more reliably identified, than ceremonial tsantsa. AbstractThis is an anthropological investigation into a collection of 65 shrunken human heads, to determine if new characteristics can be identified to facilitate the differentiation between ceremonial tsantsa and commercial shrunken heads. Ceremonial tsantsa refers to shrunken heads mummified as war trophies within the ancient traditions and rituals of the Amazonian Shuar, Achuar, Awajún/Aguaruna, Wampís/Huambisa and CandoshiShapra (SAAWC). Commercial shrunken heads are comparatively modern objects constructed specifically for the collector market of the past. Low earning individuals in South and Middle America, outwith the SAAWC culture, who had access to corpses and appropriate medical or taxidermy provisions, produced these for trade purposes. These heads were made in abundance and do not present the same historical value or heritage as ceremonial tsantsa. The relevance of an accurate provenance for heads may directly impact museums, with regard to identifying the authenticity of a specimen and how they should handle any potential requests to return such artefacts to their cultural homes.Complying with current anthropological standards, a total of 6 ceremonial tsantsa and 36 commercial heads were identified. Greater confidence is prescribed to the assignment of commercial heads as their morphological appearance is at odds with the highly standardised presentation of ceremonial tsantsa. Many indicated that the processor had access to modern resources such as gloves and fine suturing equipment, which were not typically available to the SAAWC. Since traders sometimes closely replicating ceremonial tsantsa when shrinking and decorating heads for trade, limited certainty can be prescribed to this category.Minor deviations in ceremonial design resulted in 23 heads being defined as ambiguous in origin.Each head was examined by manual inspection, infrared reflectography (IRR), CT and microscopic hair analysis, with ten new differentiating characteristics identified.
